Data Grid Event Handler
I am using .net 2005 beta. I have a basic data grid loading as I would like. I have added a button to each row but cannot seem to create the proper event handler for my code behind.
The closest I think I have come is:
Code:
Sub DataGrid1_MyCmd(ByVal sender As Object, ByVal e As DataGridCommandEventArgs)
Dim bn As Button
If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
bn = CType(e.Item.Cells(4).FindControl("MyCmd"), Button)
bn.Attributes.Add("onclick", "return confirm('Are you sure you want to delete this item?');")
End If
End Sub
This code runs error free but does not execute
If I add a handler
Code:
Sub DataGrid1_MyCmd(ByVal sender As Object, ByVal e As DataGridCommandEventArgs) Handles DataGrid1.Command
Dim bn As Button
If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
bn = CType(e.Item.Cells(4).FindControl("MyCmd"), Button)
bn.Attributes.Add("onclick", "return confirm('Are you sure you want to delete this item?');")
End If
End Sub
I get an error an unmatched signature error.
What should I be doing?
Data Grid's ButtonClick Event..How Can I Drop Down A List?
I've got a DBGrid that I have set a certain Column's Button Property to True. At runtime, when the button is clicked, I would like a drop-down list to be displayed, or something similar to give the user two choices.
For example, I have a column labeled "Processed". When I click on the cell, the cell's button appears and if the user clicks on that button, a list should drop down with two choices, "True" and "False".
I cannot find any information on this, but saw in the MSDN the following:
"Typically, you enable the column button when you want to drop down a Visual Basic control (such as the built-in combo box, a bound list box, or even another DataGrid control) for editing or data entry. When the button in the current cell is clicked, the ButtonClick event will be fired. You can then write code to drop down the desired control from the cell."
How can I create a "built-in" combo box?
Thank You!!
Unable To Change Data In The Data Grid
Dear sir/madam;
I have a form with a data grid written with VB version 8176. The project is working fine with my computer using this version 8176 but when I run the same project at school. The data grid is not allowing me to change any data in any column in the grid at all. The version of VB in school is 9899 and have SP5 as well. Could you please help me resolve this problem. My school project is due in one more week and I have to get this data grid working. Please help, please!
Thank you for your attention.

Data Grid: How To Enter And Change Data?
Hi, folks!
I've added a Datagrid control to my form and have set its properties like this:
AllowAddNew = false
AllowDelete = false
AllowUpdate = false, on the form load event
There's a button called "Add New", with the following module:
MyDatagrid.AllowAddNew = True
Mydatagrid.AddNewMode
But when I click this button, this error message appears:
Invalid use of property (regarding the 2nd line, property .AddNewMode
There's another button called "Changes", with the module:
MyDataGrid.AllowUpdate = True
MyDataGrid.EditActive
And the same error message appears for the .EditActive property.
What I am doing wrong?
I'd like to allow the user to change or add new records only after clicking the proper buttons. I've done with another forms, but that's the 1rst. time I work with the DataGrid Control.
Please, help!
Thanks in advance for any ideas,

Change The Data Field In Data Grid
Hi all,
I have an ADODC control, namely Adodc1, having the sql statement as below :
sqlstr = "select to_char(IN_DATETIME,'dd-mm-yyyy hh24:mi:ss'),
, other_field from table1"
and the Adodc1 is bind to DataGrid1.
Upon clicking the IN_DATETIME column header, i wish to sort the recordset by IN_DATETIME. I use the following codes in the DataGrid1_HeadClick(ByVal ColIndex As Integer) function:
***************************************************************
strColName = DataGrid1.Columns(ColIndex).DataField
Adodc1.Recordset.Sort = strColName & " DESC"
***************************************************************
However, it gave me error as below whenever i click on the IN_DATETIME column :
****************************************************************
run-time error '3265': Ado could not find the object in the collection corresponding to the name or ordinal reference requested by the application.
****************************************************************
I believe it is because of the sql i used in Adodc1 as the data field name in Adodc1 is recognised as :
to_char(IN_DATETIME,'dd-mm-yyyy hh24:mi:ss')
Is there anyway i can set the ADODC recordset field name manually in the code? I tried :
Adodc.Recordset.Fields(ColIndex) = strColName
but it gave me the following error :
****************************************************************
run-time error '91':
Object variable or With block variable not set
***************************************************************
Due to some reasons, i must use to_char(IN_DATETIME,'dd-mm-yyyy hh24:mi:ss') in my sql instead of IN_DATETIME.
Can anyone give me some hints how should i go about it? Thanks in advance.

How To Run Event On Data Change Or Cell Lostfocus?
Hello,
I am trying to use VBA to validate data as the user inputs it, and have XL stop them and run an event if and when they input incorrect data.
The code I am using right now looks like this :
Private Sub Worksheet_selectionChange(ByVal Target As Range)
If Application.activeCell = Worksheets("mysheet").Range("A1") Then
checkTime (Application.activeCell.Value)
Else
End If
End Sub
The checkTime is a simple method that checks to make sure the entered value is less than 24 and greater than 0. If I enter invalid data, XL won't run the event until I click back on the cell I just entered it into (when A1 GAINS focus, in this example). I need it to run the event after the data is entered and before focus is lost on the current cell.
I looked around, and saw that there is a LostFocus event , but I can't seem to get it to work. Also, I cannot seem to use the Target argument in the _selectionChange method for anything. I'd like to use
If Target = Range("A1") Then
.. instead of ..
If Application.Activecell = Worksheets("mysheet").Range("A1") Then.
I realize that if I was able to utilize Target in the above manner, I'd still have the same problem, I'm just curious. All of the examples shown for use of Target are in a different manner, such as
Target.Font.Bold = True (or something like that.)
Am I thinking of this argument in the wrong way ?
Any advice would be appreciated.
Thanks,

Need Help Validating Data In A Textbox W/ Change Event
Every time I type a number in, it gives me the "Subscript out of Range" error.
VB Code:
Private Sub txtAnswer_Change() If txtAnswer.Text <> " " And txtAnswer.Text >= 0 And IsNumeric(txtAnswer.Text) Then cmdCheck.Enabled = True Else MsgBox "Please enter valid data", 16 cmdCheck.Enabled = False End IfEnd Sub
Curious 'Validate' Event Behaviour
Hi folks.
Haven't been around for a bit, so I thought I would throw a good one at you for good measure.
I am writing a front-end to an application, which gathers an amount of input from the user, (via textboxes, checkboxes etc), and then attempts to store this in an Oracle database. To perform step-by-step input validation, I am using the 'Validate' event on the controls.
In the majority of cases, this works a treat, and provides excellent results. However some of the validations contain a small data retrieval, (where the input data is checked against a value in the database).
Now here is the odd part. If I key a value into a box that is validated against the database, and then click on a button somewhere else on the screen, (rather than tabbing to the next control), the following happens.
1. The 'Validate' event of the textbox fires.
2. The button becomes 'depressed' on the screen, but stays that way even with the mouse button released.
3. The 'Validate' event completes its work.
4. The 'Click' event of the button never fires, even if the 'Validate' event allows the focus to shift.
Once in this state, the button remains depressed, so long as the mouse is held over it. If you move the pointer out of the bounds of the button, the button returns to the 'raised' appearance', but sinks in again if you return the pointer to the bounds of the button control.
I know this problem can be cured by setting the 'CausesValidation' property of the button to False, but this defeats the object in my opinion. I need the textbox to validate before it permits the click of the button.
Any ideas?

Datagrid Data Change Failed To Fire Recordset Fieldchangecomplete Event?
Hello,
I have a question about DataGrid and ADO recordset. I am using VB6 with SP5.
I have a DataGrid bind to an ADO recordset. When I change a text data on the DataGrid, the ADP recordset fieldchangecomplete event never fire. Is there anyway to force the ADO recordset fieldchangecomplete event to fire?
On the other hand, I also have textboxes bind to another a ADO recordset, when I change the data on the textbox, the ADO recordset fieldchangecomplete event did fire. It seems to me changing data on the DataGrid will not fire the ADO recrdset fieldchangecomplete event. It is ture?
Thanks.
How To Change The Behaviour Of Close Button
Hello friends
i am making an application which starts in minimised state and it displays an icon in the system tray (taskbar). rightclicking on the icon diaplays a menu . leftclicking on the icon brings up the application.
what i want to do is that when somebody has the application it will show on the screen. then when he click the close button
( the cross on the top right corner ) to close the application the application ahould hide and the icon should appear in the taskbar again
i have made the application but when i click on the close button the application ends and the icon also disappears from the task bar ( i dont want that to happen)
since the application i have made must monitor the systen time constantly and when it matches a particular time it should fire a subroutine.so i dont want it to stop unless the person explicity clicks exit from the menu.
i want something like yahoo messenger, even when the person click in the close cross to close the messenger it still remains working which is shown by the icon in the system tray
please tell me how to do this??

Setting Global Timer Behaviour According To FileListBox Behaviour????
Hi folks, still fresh here so not sure if I'm using the right terms but here goes...
I would like to set my Timer enabled behaviour (globally speaking) on my form according to FileListBox visibility behavour. Something like the code below would do (which of course doesn't work) but that's the idea. Right now I have to insert the if condition every time an event triggers my File1 to be visible or not visible ( which is quite a few times in my current project).
Any sugestion welcomed, thanks
VB Code:
Private Sub Form_Load() With File1 If .Visible = True Then Timer3.Enabled = False If .Visible = False Then Timer3.Enabled = True End WithEnd Sub
KeyPress Event And TextBox Change In Same Private Event
First off, thank you for this forum...I'm extrememly new so be kind as I know this is a simple task but I'm stuck off in the weeds.
My goal is as someone enters an IP address octet in a textbox, when they get to either 3 characters entered or press the "." key, it will move them to the next octet textbox. I figured how to do it as a keypress event or by text length but how do I monitor both?
I've tried the following:
Private Sub txtIPentry1_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtIPentry1.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(46) Or txtIPentry1.Text.Length > 2 Then
e.Handled = True
txtIPentry2.Focus()
End If
End Sub
I just don't know how to combine a txtIPentry1_TextChanged and txtIPentry1_KeyPress event into the same set of code.
Thanks for helping the newbie....
Change Textbox.Text Without Firing Change Event?
This is probably going to be one of those threads that just shoots down the list but I was wondering if there is a way to change the contents of a textbox through code that won't fire its change event. I don't think it is possible but I have seen some pretty cool stuff on the forum and thought I'd give it a shot. Thanks.

Help With MSFlex Grid Or Data Grid
Can anyone direct me to a user-friendly discussion on either MSFlex Grid and data grid controls. I’m trying to mimic the appearance of an excel spreadsheet in a VB form and was told one of those grids would do it. However I have never used either before and cannot find any posts/lessons/pages on MSDN that clearly explain how to do what I want.
Which, in case it helps is this: Currently have an excel spreadsheet with dates across the column headings and room numbers for row headings, cells are filled with patients names for each room and the respective dates they are staying (which is taken from our db).
This is mainly used by our volunteers to quickly see if beds are available for additional patients, however, as the info is entered once in the database and again in the spreadsheet there have been numerous discrepancies. As many of the volunteers are older we don’t want to change the appearance too much.
If the info is in the db I figured there must be some way to mimic the spreadsheet in VB, which I’ve been informed is the aforementioned grids. But I have no idea how to set this up and cannot find a clear explanation.
ANY assistance is greatly appreciated on this one!
Cheers

Change Event
Hi, all!
I'm having problems getting the Change Event to work - that is to say that it does not work for all changes. It works fine if I i.e type in the designated range, but for other changes it does not work. Thing is that I have a live price feed (from Bloomberg) that updates the cells but this does not trigger the Change Event.
The code used is the following:
Sub worksheet_change(ByVal Target As Excel.Range)
Dim vrange As Range
Set vrange = Range("M9:M13")
If Union(Target, vrange).Address = vrange.Address Then
Unload UserForm1
Call UserForm1_Show
End If
End Sub
Please help!
Change Event
brain dead moment....
what is the change event syntax for .Net
Change Event
I have a program that grabs data from an ADO data source.
ie. L_Name Once the data is saved to a form text box (ie. Text1.text), I close the recordset. (not a data aware cont.)
In the change event for the text1 box, I have a command to turn a Cancel button on. The problem is, the button come on right away, before the user changes the contents of this box.
Any ideas?

Change Or Key Up Event
Hi,
I have a Form with 10 Text Boxes, 9 Dropdown Combo Boxes, and 4 List Boxes. On the form is a label (lblCham) whose BackColor I want to have change to grey if the user makes any of the other controls on the page change from their original setting / text.
Do I have to have a Change Event or a Key Down event for every control, or is there a better way?
Change Event
Does anyone know how to determine if the user manually changed something in a textbox or if the change occurred programmatically in a textbox (i.e., clicking on a navigation button like 'next record' and writing that data to the textbox triggers the 'change' event)?
My dilemma is I have a form with three textboxes on it. The form's datasource is an Adodb recordset, so I have to force the txtBoxes to 'change' everytime the user clicks on a navigation button which triggers the 'change' event, right?...because the txtBoxes can't be directly linked to the datasource. In the 'change' event of each of the txtBoxes I have the following flag:
Code:
Private Sub txtBox_Change()
blnDirty = True
End Sub
If blnDirty = True, a msgbox asking the user if they want to save the changes appears. I only want this to happen if the user actually made a change. Any suggestions????
Change Event
hi i need to disable the enter button if there is no characters typed on the text box and when they type then the enter button becomes enabled. i need to use the change event can someone help me out?

I set a boolean to true for every textbox change event but it still isn't working. I've never used this event before so I think I'm just not getting what it does. Could someone please explain?
Change Event
How does the Change3 event actually work?

Ok I know somebody know this how do you detect the change event in a label at run time.
