Hi,
How do I set the parameters of an SqlDataSource programatically?
I have tried the following...
dsDraftBudgetPI.SelectParameters.Add(new Parameter("@person_id", TypeCode.Int32, pID.ToString()));
But that didn't work. I already have the parameter defined at design time so I don't need to create one I just want to set its value and then bind it to a ListBox to display the result.
Thanks,
Scott
I have an SQLDataSource. The SQL is
SELECT UserName, Category, ItemDescription, Size, Price, Reduce, Donate, Sold, ItemNumber, SoldDate, SoldPrice, PrintedFROM Tags WHERE (Printed = @Printed1 OR Printed = @Printed2 OR Printed = @Printed3) ORDER BY ItemNumber DESCThe bit field "printed" can be NULL, True or False.In the Selecting event of the SQLDataSource I have the following to show ALL records. But it does not work. If I remove these parameters it show ALL records.
e.Command.Parameters("@Printed1").Value = Nothing 'ASP.NET 2.0 using Visual basice.Command.Parameters("@Printed2").Value = Truee.Command.Parameters("@Printed3").Value = False
What am I doing wrong???
Thanks

I have a sqlDatasource with 3 parameters based on the input of 3 text boxes on the page. The datasource returns sales details for a company based on a from and to date. I am attempting to set the value of the 3 parameters in the Selecting event of the datasource control but I'm not getting any data back. If I set the values literally then I get data back. Also when I step through the code I can see the 3 parameters getting their values from the textboxes and the drop down list as they should. This is driving me insane as I'm new to .net and just can't see what is stopping me retrieving the data when using the form fields to set the datasources parameters. Below is the aspx and the code behind for the page.

View 3 Replies View RelatedHello all,
Ok, I finally got my SqlDataSource working with Oracle once I found out what Oracle was looking for. My next hurdle is to try and set the Update Command and Parameters dynamically from a variable or radiobutton list. What I'm trying to accomplish is creating a hardware database for our computers by querying WMI and sending the info to textboxes for insertion and updating. I got that part all working nicely. Now I want to send the Computer name info to a different table column depending on if it is a laptop or desktop. I have been tossing around 2 ideas. A radiobutton list to select what it is and change the SQL parameters or do it by computer name since we have a unique identifier as the first letter ("W" for workstation, "L" for Laptop). I'm not sure what would be easiest but I'm still stuck on how this can be done. I posted this same question in here a few days ago, but I didn't have my SqlDataSources setup like I do now, I was using Dreamweaver 8, it is now ported to VS 2005. Below is my code, in bold is what I think needs to be changed dynamically, basically i need to change DESKTOP to LAPTOP...Thanks for all the help I've gotten from this forum already, I'm very new to ASP.NET and I couldn't do this without all the help. Thanks again!

Hi All,
I'm trying to set the SelectParameters of SqlDataSource from the code behind.

How can I do it??

I am trying to set the value of a SqlDataSource parameter named "InvestmentGroup" with the following code:ProjectData.SelectParameters["InvestmentGroup"] = Request.QueryString[0];ProjectData.DataBind();When I try this, I get an error saying that the right side is a string and the left side is not....but I cannot find a property of the SelectParameters["InvestmentGroup"] object like Value or something that would allow me to set the value of the parameter with a string. Please help!
View 4 Replies View RelatedI need to provide defaults and sometimes overrides for items in SQLDataSource's UpdateParameters. I am attempting to do this in a FormView's ItemUpdating and ItemInserting events as follows: //========================================================================
// FormView1_ItemUpdating:
//========================================================================
protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs e) {
// not sure if this is the bets place to put this or not?
dsDataSource.UpdateParameters["UpdatedTS"].DefaultValue = DateTime.Now.ToString();
dsDataSource.UpdateParameters["UpdatedUserID"].DefaultValue = ((csi.UserInfo)Session["UserInfo"]).QuotaUserID;
}
In the example above I am attempting to set new values for the parameters which will replace the existing values. I have found that using the DefaultValue property works ONLY if there is no current value for the parameter. Otherwise the values I specify are ingnored.The parameters of an ObjectDataSource provide a Value property but SQLDataSource parameters do not.How can I provide an override value without needing to place the value in the visible bound form element???If you can answer this you will be the FIRST person ever to answer one of my questions here!!!Thanks,Tony
I thought this would be easy. I have a repeater control and a sqldatasource control. I am trying to filter the select statement using DateTime.Now.ToString() and keep getting an invalid date string format. The control is on a content page in my asp.net site. On the master page this <%= DateTime.Now.ToLongDateString() %> works to display the current date. If I try and put <%= DateTime.Now.ToString() %> in the Default value of the SelectParameter it does not work. No intellisense either so I am assuming I am missing something. Here is the code... pretty basic really.
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="sqlDSnews">
<ItemTemplate>
<h3><%# Eval("newTitle")%></h3>
</ItemTemplate>
</asp:Repeater>
<asp:SqlDataSource
ID="sqlDSnews"
runat="server"
ConnectionString="<%$ ConnectionStrings:XXXX%>"
SelectCommand="SELECT [newTitle], [newsDetails], [dateExpires], [newsImage], [dateCreated] FROM [News] WHERE (([GroupID] = @GroupID) AND ([dateExpires] >= @dateExpires))">
<SelectParameters>
<asp:QueryStringParameter DefaultValue="0" Name="GroupID" QueryStringField="Gid" Type="Int32" />
<asp:Parameter Name="dateExpires" DefaultValue='<%= DateTime.Now.ToString() %> 'Type="DateTime" />
</SelectParameters>
</asp:SqlDataSource>
** NOTE the DateTime does not show up in blue - if that helps with a solution **
Can you dynamically set the name of the table in the SelectCommand section of the SqlDataSource? (If it is relevant, I code in C#)
For example,
<asp:SqlDataSource runat="server" ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:Test-MySQL %>" ProviderName="<%$ ConnectionStrings:Test-MySQL.ProviderName %>" SelectCommand="SELECT * FROM TestTable">
I would like to replace 'TestTable' with the name of a table that is extracted from a string array in the code-behind.
Appreciatively,Peter
Hi, I have created a search page which needs to perform different
search function in same page. I have setuped a sqldatasource then
manual
setup the connection string and command inside the codefile. So the
select command can be various depends on the event. The problem is
all of those setting will be reset after I click on the pageindex in
the girdview control to go to next pages. Since this gridview is linked
with this sqldatasource control, I need to restore the connection
string/command when user choose decide to view next page of data inisde
the
gridview.
I think I must have done something wrong in here becuase it will end up
retrieving the total amount of data when everytime user choose to
view next
or perivous page.
Can someone give me a hand on this ? Thanks
Here is the code I am trying to use to set a update parameter at runtime. (Depending on what linkbutton a user clicks on the STATUS_ID value will change.)
SqlDataSource1.UpdateParameters("STATUS_ID").DefaultValue = 33332Here are my parameters:

<asp:Parameter Name="CUSTOMER_ID" Type="Decimal" />
<asp:Parameter Name="RECEIVED_BY" Type="String" />
<asp:Parameter Name="CALL_DATETIME" Type="DateTime" />
<asp:Parameter Name="AREA_ID" Type="Decimal" />
<asp:Parameter Name="CLASS_ID" Type="Decimal" />
<asp:Parameter Name="STATUS_ID" Type="Decimal" /></UpdateParameters>Sqldatasource1 is the name of my datasource control. Any thoughts?
Is
it possible to specify different parameters for the
select/update/delete stored procedures used by a sqldatasource? When I
'configure the datasource' it lists the different stored procedures for
each command, but when it comes to specifying the parameters it only
lets me do so for the select command. Is there another way to do this
for the other commands?
I have tried doing it manually in the aspx file (using the
DeleteParemeters etc), but I don't know how to reference a specific
cell in the selected row of the gridview for the controlparameter). Any
thoughts?
Hello I need help withsetting parameters for SqlDataSource

string login = Context.User.Identity.Name;
SqlConnection conn1 = new SqlConnection("server=CR\SQLEXPRESS;database=myData;integrated security=SSPI");
conn1.Open();
SqlCommand cmd1 = new SqlCommand(" SELECT IN_OUT.TIME_START, IN_OUT.TIME_END, FROM IN_OUT INNER JOIN USER ON USER.USER_ID=IN_OUT.RC_USER_ID where USER.LOGIN=@LOGIN", conn1);
cmd1.Parameters.Add("@LOGIN", SqlDbType.NVarChar, 50);
cmd1.Parameters["@LOGIN"].Value = login;
1.Parameters.Add("@LOGIN", SqlDbType.NVarChar, 50);
cmd1.Parameters["@LOGIN"].Value = login;

View 3 Replies View RelatedI need to do some select & update from VB code behind a web page. Using VS2005, ASP.NET.
To me, the most logical approach would be to use a SqlDataSource. I can select the connection string, predefine select, insert and update queries and call the select(), and other commands from this control.
I need to use parameters in the queries but I cannot connect parameters straight to controls, I need to do it from VB. But nowhere can I find how to set the parameter values from code. I can find all kind of examples from VS2003 or using SqlCommand, but it should be possible from this control as well, but the help documentation is very poor in this respect.
Please provide me with some example.

Hello.
I have one dataset with a few parameters.
Each parameter get its available values from the some dataset.
So if I have the main DS whice is:
"select name,age,sex from table1 where age = @age and sex = @sex"
The available values for the parameters "age" and "sex" are those datasets:
"select distinct age from table1" and
"select distinct sex from table1".
The problem is thet the query on table1 takes a lot of time and in this case I need to run her three times.
Is there a way to initialize the parameters values in one query excution and save some time?
Thanks.
I am trying to get familiar with Microsoft neural networks to predict property prices. The results are better but I wanted to amend the default parameters passed to the neural network.
So on MINING MODEL TAB when I right click and go into SET ALGORITHM PARAMETERS, I can't see any parameters there, if I try to enter a parameter for example MAXIMUM_STATES and process the model I get the following error message
"The 'maximum_states' data mining parameter is not valid for the 'My Model' model"
I also added a decision tree model to the same structure and when go into SET ALGORITHM PARAMETERS pop menu it comes with many pre populated parameters with default values.
My question is that why I am unable to add parameters to the NEURAL NETWORK and why it does not come with pre populated parameters like DECISION TREES.
Your help will be much appreciated.
Hello!
I am pulling my hair out over this latest problem. I'm trying to do a simple SQL SELECT statement by taking values from textboxes and inserting them into the WHERE part of the statement. I'm using MySQL and have to use ? prefix for all inserts, that I have working by the way. Now for some reason I cannot get the values from the text boxes to replace the prefixes! Here is my code:
private void submitLogin(object source, EventArgs e) {
if (isPassword(password.Text.ToString()) && isEmail(username.Text.ToString()))
{
ValidateCustomer.SelectParameters["c_email"].DefaultValue = "fish";
ValidateCustomer.SelectParameters["c_password"].DefaultValue = "cakes";
test_label.Text = ValidateCustomer.SelectCommand.ToString();
}
else {
test_label.Text = "Username or Password Incorrect";
}
}
<asp:SqlDataSource runat="server"
ID="ValidateCustomer"
ProviderName="System.Data.Odbc"
ConnectionString ="<%$ connectionStrings:MySQLDatabase %>"
SelectCommand ="SELECT * FROM customer_details WHERE (Customer_Email = ? AND Customer_Password = ?)">
<selectparameters>
<asp:parameter name="c_email" type="String" />
<asp:parameter name="c_password" type="String" />
</selectparameters>
</asp:SqlDataSource>
I have omitted obvious code. The test label, when updated, shows the SQL statement but with the ?. I also use controlparameters that took the values directly from the textboxes but again this did not work. I'm really stuck with this one. Your help is much needed!

I have a GridView bound to a SqlDataSource. On page load I would like to programmatically specify a SelectParameter value based on the role of the user. This SelectParameter will be used in my WHERE clause. The closest post I can find is http://forums.asp.net/thread/1233258.aspx but no answer was posted.
What code would I use to modify a SelectParameters value? Is it possible to reference a parameter by name (SqlDataSource1.SelectParameters["usertype"]) or does it have to be by index? (SqlDataSource1.SelectParameters[0])
Alternatively, perhaps I'm going about this in the wrong way, is there a better way to have dynamic GridView content based on the role of the user?

Hoping someone may be able to help with a problem I'm having with SSRS parameters....
My report has 2 parameters - the User Id used to login to the application and the Department(s) within the organisation. Based upon the User's role, the user may have access to data for one or many Departments.
Thus, the first parameter needs to be set in code based upon the User's login, however, the range of the second parameter (i.e. the range of Departments that the user can access) is controlled by the value of the first parameter.
The second parameter is to appear as a drop-down of Departments to which the User has access.
The report is to be produced for the selected Department.
Are you able to advise how to restrict the range of values for the second parameter based upon the value of the first parameter?
Any help is much appreciated.
I'm passing a parameter to a stored procedure stored on my sqlserver, or trying to atleast. And then firing off the update command that contains that parameter from a button. But it's not changing my data on my server when I do so.
I'm filling a dropdown list from a stored procedure and I have a little loop run another sp that grabs what the selected value should be in the dropdown list when the page loads/refreshes. All this works fine, just not sp that should update my data when I hit the submit button.
It's supposed to update one of my tables to whatever the selected value is from my drop down list. But it doesn't even change anything. It just refreshes the page and goes back to the original value for my drop down list.
Just to make sure that it's my update command that's failing, I've even changed the back end data manually to a different value and on page load it shows the proper selected item that I changed the data to, etc. It just won't change the data from the page when I try to.
This is what the stored procedure looks like:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ALTER PROCEDURE [dbo].[UPDATE_sp] (@SelectedID int) AS
BEGIN
UPDATE [Current_tbl]
SET ID = @SelectedID
WHERE PrimID = '1'
END

And here's my code behind:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Imports System.Data
Imports System.Data.SqlClient
Partial Class Editor
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
Saved_lbl.Text = ""
Done_btn.Attributes.Add("OnClick", "window.location.href='Rpt.htm';return false;")
Dim View1 As New DataView
Dim args As New DataSourceSelectArguments
View1 = SQLDS_Fill.Select(args)
Dim Row As DataRow
For Each Row In View1.Table.Rows
Ver_ddl.SelectedValue = Row("ID")
Next Row
SQLDS_Fill.Dispose()
End Sub
Protected Sub Submit_btn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Submit_btn.Click
SQLDS_Update.Update()
Saved_lbl.Text = "Thank you. Your changes have been saved."
SQLDS_Update.Dispose()
End Sub
End Class

Any help is much appreciated.
If I have a lot of dropdowns of similar type but only differ in one field, is there a way to set parameters so that the dropdownlist can specify what the parameter values are?
For example dropdowns: expenseaccount, incomeaccount, assetaccount
SqlDataSource:
SelectCommand="select accountid,accountname from accounts, accounttypest where accounts.accounttypeid=acounttypes.accounttypeid and accounttypes.accounttypename=? order by accountname"
<SelectParameters>
<asp:Parameter Name="accountTypeName" Type="string" />
</SelectParameters>
-------
I would like expenseaccount to be able to specify "EXPENSE", incomeaccount to specify "INCOME", etc...
Or is sqldatasource reusage bad practice?
(damn vs2k5 colors)
I have a sqldatasource in a wizard. When I click the finishbutton in the wizard I want to insert some values (from textboxes, dropdownlists in my wizard) into a mysql-database. For this I use parameters, I add some values in the design mode and some in codebehind. The parameters in codebehind are added perfectly but the other parameters in designmode (name, email) just inserts null. Why? My datasource: <asp:SqlDataSource
ID="dsInsert"
InsertCommand="INSERT INTO tbltest (name, email, city) VALUES (?name, ?email, ?city)"
runat="server"
ConnectionString="<%$ ConnectionStrings:conn %>"
ProviderName="MySql.Data.MySqlClient">
<InsertParameters>
<asp:FormParameter Name="?name" ConvertEmptyStringToNull="true" Type="string" FormField="name" />
<asp:FormParameter Name="?email" ConvertEmptyStringToNull="true" Type="string" FormField="email" />
</InsertParameters>
</asp:SqlDataSource> The codebehind: protected void finishButtonClick(object sender, EventArgs e) { dsInsert.InsertParameters.Add("?city", TypeCode.Int32, city.SelectedValue); dsInsert.Insert(); }
