Gridview And DropDownList

Oct 18, 2006

Hello:I have add a DropDownList to my GridView and binded the dropdownlist to a field from a select statement in the SQLDataSource. I have EnabledEditing for my GridView. The GridView is populated with information from the select statement. Some of the information returned from the select statement is null. The field where the dropdownlist is binded it is null in some cases and does not have a value that is in the dropdownlist so I get and error when I attempt to do an update. 'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value Is there a way to get around this besides initializing all the columns in the table that are going to be binded to a dropdownlist to a value in the dropdownlist?

Sqldatasource And Dropdownlist

Nov 8, 2006

 
Hi,
I have sqldatasource that i set up in VS2005.  i have a dropdownlist using this source.  Data is added to the db from a different app and i want this dropdownlist to use the latest data on a page refresh. 
However i can not refresh the sqldatasource - the dropdownlist does not show the latest additions to the db - i  hae to rebuild to see them.  i tried turnning 'enable caching' and 'enable viewstate' to false but no luck.
How is this done.
 
Thanks.

Can You Use Substring In ASP.NET On A DropDownList ?

Oct 26, 2007

I'm using the GridView to display some accounting infromation. I have a project where I have a 14 character control number. I would like to have a dropdown list to select the account classification of records to be displayed. The accounting classification is the first two characters of the control number.  So the dropdown list needs to show unique first two characters and the GridView will be filtered on these two characters.  I have been trying to use "substring" in the ASP.NET code; not even sure you can.
Any suggestions on how to accomplish this would be greatly appreciated.  See code below:
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" DataSourceID="SqlDataSource2"
DataTextField="control_num" DataValueField="control_num">
</asp:DropDownList><asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:GPCRReportsConnectionString %>"
SelectCommand="SELECT DISTINCT [substring(control_num,1,2)] FROM [Request]"></asp:SqlDataSource>
ERROR: Invalid column name 'substring(control_num,1,2)'.

Not Inserting Dropdownlist

Populating Dropdownlist

Mar 23, 2006

I've got the following code and it's not really what I want. With the below code I can select in a dropdownlist a value and in the other dropdownlist the correspondending value will be selected. But when I select a value the second dropdownlist won't be filled with all the data in the database. It is filled only with the correspondending value and not with the rest of the value.

Handle Null Value For DropDownList?

Nov 11, 2006

Using asp.net 2.0 and visual studio 2005. The question is regarding the following ER diagram: I've made Firstname, lastname, buildingID and RoomNum all required fields. I've got a modified GridView that displays all of the table Faculty columns.  It's been modified so the BuildingID and DepID are resolved to their actual field names and displayed in a DropDownList.  In the dropdown list I used for inserting (a seperate DetailsView control), I manually inserted an item into the Department dropdownlist which had the text "-- Select a Department --" with a value of -1.  MS SQL didn't like that -1 value so I wrote the following code to fix it:  protected void dsFaculty_Inserting(object sender, SqlDataSourceCommandEventArgs e)
{
if (e.Command.Parameters["@DeptID"].Value.ToString() == "-1")
{
e.Command.Parameters["@DeptID"].Value = null;
}
} That means of course DeptID is null, which is ok.  The problem arises is when I try to edit that row in the GridView.  I get the an error 'ddlDepartment' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: valueIdeally, I'd like to make the dropdown list in the GridView show "-- None --" for the DeptID if it comes across a null value.  I already tried playing around with the Command.Parameters in the dsFaculty_Selected function, but it didn't work.  Ideas?

Clarification For 'WHERE' Statement In A Dropdownlist

Feb 12, 2008

My goal is to populate a dropdownlist with only with users that are "Techs".  I am using the membership database that you ccan set up through VWD.  I added this column to the aspnet_Users table: IsTech as bit datatype. I thought I had the right SQL statement but apparently not, because I get an Invalid column name 'True'.Here is my statement: <asp:SqlDataSource                                     ID="SqlDataSource3"                                     runat="server"                                     ConnectionString="<%$ ConnectionStrings:HRIServiceConnectionString1 %>"                                                                    SelectCommand="SELECT [UserID], [FirstName]+ ' ' + [LastName] AS techid FROM [aspnet_Users] WHERE [isTech] = True ORDER BY [LastName], [FirstName]">                                </asp:SqlDataSource>

DropDownList Inside CreateUserWizard

Mar 25, 2006

I am using the createuserwizard, and have set up my own profile table which hold first name, last etc. In my CreateUserWizard, the field for Vendor is a dropdownlist that is to be populated from a list in a database. I set up the form without the createuserwizard, and everything went skippy, but when I placed it into the wizard, I now cannot access the control of the dropdownlist.
I have tried doing..
Using SqlConnection As New SqlConnection(WebConfigurationManager.ConnectionStrings("Personal").ConnectionString)Dim VendorID As DropDownListVendorID = CType(CreateUserWizard1.FindControl("VendorName"), DropDownList)
Dim MyReader As SqlDataReaderDim sel As String = String.Format("SELECT VendorID, Name FROM Vendors")Dim MyCommand As SqlCommandMyCommand = New SqlCommandMyCommand.CommandText = selMyCommand.CommandType = CommandType.TextMyCommand.Connection = SqlConnectionMyCommand.Connection.Open()MyReader = MyCommand.ExecuteReader(CommandBehavior.CloseConnection)But when I go to databind, it says:Object reference not set to an instance of an object. VendorID.DataSource = MyReaderLine 30:             VendorID.DataValueField = "VendorID"Line 31:             VendorID.DataTextField = "Name"

Dropdownlist Database Search

Mar 19, 2008

Hi all.

I have a huge problem that ive been sitting with for awhile.

I have a web page with 4 dropdownlist boxes on it

Gender:
Race:
Field:
Location:

Now a user can search a SQL db from selecting values from these 4 dropdownlist boxes which are equal to values in the db obviously.

when they have done that and pressed submit a Gridview is populated with the people corresponding details and the user is able to view each row seperately.

Now the problem i am having is that when i havent used all 4 selections for eg

Gender: null (no value selected)
Race: Black
Field: Accounting
Location: Los Angeles

then no information is returned from the db in the gridview.
im using a sqldatasource to populate the gridview and here is the query string that i am using :


Code:

sql
SELECT [title], [gender], [initials], [name], [surname], [birthdate], [postaladdress], [suburb], [city], [zipcode], [criminalrecord], [drivers], [maritalstatus], [dependants], [citizenship], [province], [contactref], [hometel], [cell], [jobtitle], [relocate], [emmigrate], [email], [worktel], [enddate], [startdate], [FIELD], [education], [company], [positionheld], [jobdescription], [contactperson], [contacttel], [startdate2], [contactperson3], [jobdescription3], [positionheld3], [company3], [enddate3], [startdate3], [contacttel3], [other] FROM [cvinformation] WHERE (([race] = CASE WHEN @race IS NOT NULL THEN @race ELSE [race] END) AND ([province] = CASE WHEN @province IS NOT NULL THEN @province ELSE [province] END) AND ([education] = CASE WHEN @education IS NOT NULL THEN @education ELSE [education] END))



what i want to do is whether the user doesnt choose any selection and leaves the choice null that ALL the information in the table of the db be shown and even if they only choose 2 values and leave the others null then it still brings back the information from the criteria chosen..

Is this possible.?

How To Make A Dropdownlist Empty

Nov 18, 2006

I have a listbox that lists countries....and if you choose a country, another listbox show cities in that country (fetched from a sql database)....And if you then chose a city in the second listbox, a dropdownlist will show restaurants in the city....(also fetched from a sql-database)...

Ok...I hope you understand...now to the problem....:

If you first chose a country, a city and a restaurant but then want to chose another country in the first listbox, the dropdownlist for the restaurants is still there filled with restaurants for the first country...I dont know how to "remove" the restaurants so that the dropdownlist is blank if someone switch country....

I think I need to do something in countryListbox_SelectedIndexChange....but I dont know what to write there....

I know that I can make the dropdownlist invisible by entering the following code:

sub countryListbox_SelectedIndexChange

    dropdownlistRestaurants.visible = false

End sub

But I want it to be visible all the time!

Do you know what I could do?

Using DropDownList And TextBox To Filter Results...

Aug 5, 2006

Hey all,
I've been searching for a while and haven't really found an answer for what I'm trying to do. Here it all is and someone can tell me if I'm going in the wrong direction to solve this.
I have a textbox set to a parameter of "SearchString" and a DropDownList with the SelectedValue paramter of "FilterValue". The parameters work, I've tested that. So here is the problem.
I am trying to use the "FilterValue" to pick the field that the "SearchString" searches with a  LIKE statement (e.g. SELECT * FROM dbo.Units WHERE (@FilterValue LIKE '%'+@SearchString+'%'))
This, I've found out, doesn't work. I have this setup with a DataLayer.vb in my App_Code directory handling the SQL calls, while the normal CodeBehind is in the typical "Default.vb" page.
I will post code later as I don't have access to it right now, but if anyone can explain how a filter like this would work I would appreciate it!
Thanks,
 
-Matthew

Is It Possible To Dispaly All Columns For A Record In A Dropdownlist

Jul 27, 2007

Say a record has four columns in { Emp#, firstName, secondName, thirdName, spouseName }.
Now if you configure a sql datasource for a dropdownlist to return all columns, only Emp# will be displayed in the dropdownlist, the other columns wont be listed.
Is there a way to list the  values of all columns in the dropdownlist using the sql datasource or in ADO.net code.
Thanks.

Sep 12, 2007

 Hi All,
In my scenario, I am using one sqldatasource with two columns
1. Code_ID
2. Code + ' - ' + CompanyName As Display

But the problem is when my CompanyName is NULL value, it does not show my Code too....for example
Code = 1098 CompanyName = NULL

Sql query returns me NULL for this combination....and so my dropdownlist shows blank......can anyone show me the alternative.

Conditional Population Of A DropDownList Control

Apr 22, 2008

I have two DropDownList controls, ddlGroup and ddlLocation.
The contents of ddlLocation will be determined by the selection of ddlGroup. A better explanation is as follows:
ddlGroup =



ADVANCED DEVELOPMENT

DESIGN

HEAD TEST

INK R&D

JETTING

PROCESS

RELIABILITY


The SQL query that shows my logic is:
IF @Group = 'ADVANCED DEVELOPMENT'   SELECT Location FROM tblLocations WHERE Location like 'AD%'ELSE IF @Group = 'DESIGN'   SELECT Location FROM tblLocations WHERE Location like 'DE%'ELSE IF @Group = 'HEAD TEST'   SELECT Location FROM tblLocations WHERE Location like 'HT%'ELSE IF @Group = 'INK R&D'   SELECT Location FROM tblLocations WHERE Location like 'INK%'ELSE IF @Group = 'JETTING'   SELECT Location FROM tblLocations WHERE Location like 'JT%'ELSE IF @Group = 'PROCESS'   SELECT Location FROM tblLocations WHERE Location like 'PR%'ELSE IF @Group = 'RELIABILITY'   SELECT Location FROM tblLocations WHERE Location like 'RL%'
I need to define the content of ddlLocation after a selection is made in ddlGroup; how can I accomplish this using Visual Web Developer 2008 Express Edition?

DropdownLIst Box Question, Stored Procedure

Dec 11, 2005

Hi All,
I have a dropdownlist box with values  (All, Paris, London, New York) -- Cities
Another dropdwonlist box with values (All, Bank of America, City Bank, CIBC) -- Banks
And have a stored procedure that populates the info:
CREATE Procedure Search(    @City nvarchar(50),    @Bank nvarchar(50))AS SELECT     * FROM     TableA WHERE city = @city AND bank= @bank GO
If user selects a value anything other than "All" in both dropdownbox, everything is OK.
My question is, if user selects "All" in any of these dropdown combobox, how can I seach for all Cities or Banks.
SQL needs to run as a stored procedure. If it was on client end, it would be alot easier.
Any ideas?
Thanks for your help.

Proper Sorting Of Months In DropdownList

Apr 6, 2006

I'm having an issue getting the data how I want it from SQL to then populate my dropdownlist.
I have a table called SALES_BUDGR_TBL that contains alot of columns but the ones I'm focusing on are SRCURM (Month) and SRACYR (Year). What I need to do is populate a dropdownlist and show the current month first and then work backwards. The data in the dabase goes back 14 months. I created a reference table called MonthOrder that has 3 columns, MonthID, MonthName and MonthAbrv. I did this so I have a way of saying which month belongs where when sorted.
Here is the select statement I currently have. I'm joining the tables and then I want to Order by the MonthID, but I would also like it to show the 2006 records first, then goto 2005, starting with December and going down of course.
Is there anyway to do this? My Select and Results are below...
SELECT DISTINCT SB.SRCURM, SB.SRACYR, MO.MonthID, MO.MonthName FROM SALES_BUDGR_TBL SBINNER JOIN MonthOrder MO ON SB.SRCURM = MO.MonthAbrvORDER BY MO.MonthID DESC
DEC 2005 12 DecemberNOV 2005 11 NovemberOCT 2005 10 OctoberSEP 2005 09 SeptemberAUG 2005 08 AugustJUL 2005 07 JulyJUN 2005 06 JuneMAY 2005 05 MayAPR 2005 04 AprilAPR 2006 04 AprilMAR 2006 03 MarchFEB 2005 02 FebuaryFEB 2006 02 FebuaryJAN 2006 01 January
If I say only get 2006 records it works but I need a better way to do this.

Choose Default Value From DropDownList And SqlDataSource

Apr 15, 2006

Hello everyone
I'm really new to Data Presentation Controls and I already hate them couse I think they are way too complicated. Becouse of that i have already met wall many times. My last one sounds like this.
I'm triing to put a default value from, lets say SqlDataSource1 in a DropDownList that is created by SqlDataSource2. I know how to get value from SqlDataSource1 but I don't know how to use exactly that value as my default value in DropDownList.
 
Two more question.
1. Is it possible to have two different select statements in a SqlDataSource?
2. A SqlDataSource may contain an insert statement, select statement, update and delete. If I bind this SqlDataSource to a control how can I specify which of those statements will be used?
Thanks in advance
