I do an autopostback from a text box in a datagrid template. How can I
capture the event in the code behind? Handles
DataGrid1.textb oxname.TextChan ged doesn't work, and I don't see any DataGrid
events appropriate for a textchanged event.
Please respond, and save me a $245 support call to MS!

Hi Bruce,
Here's an example of what I use in one of my web apps:
HTML
----------
<asp:TextBox OnTextChanged=" txtCPL_TextChan ged" AutoPostBack=Tr ue
id="txtCPL" runat="server" .....> </asp:TextBox>
CODE BEHIND
----------------------
Protected Sub txtCPL_TextChan ged(ByVal sender As Object, ByVal e As
System.EventArg s)
Try
'do your stuff
Catch ex As Exception
'error handling
End Try
End Sub
Take care,
Michelle
I believe your technique works only for a textbox standing free on the page.
When the textbox control is part of an item template inside a datagrid, my
experience is that the codebehind does not find the textbox to allow the
textchanged event.
Do you believe your method will work on a textbox inside a cell in a datagrid?

Thank you for getting me to look at your code more closely. I realized I
needed to put the OnTextChanged=" txtCPL_TextChan ged" string manually into my
HTML. That works.
THANK YOU!

It's exactly what I use for a textbox inside of a datagrid so I know it
works. If it's not working for you let me know what errors you are
getting.
Here's a very informative site for datagrids:

Hi all,
I have a combobox control, in wich I put an autocomplete code. This code is
in the TextChanged event, but when this event fires, the Text property isn't
updated yet.
For example, if the Text property is "Foo" and I press the letter "d", the
Text property when the TextChanged event runs is "Foo". Only after the
TextChanged event be processed, the KeyDown, KeyUp and KeyPress events fires
and update the Text property.

I posted a question earlier asking whether you can assign information
to a textbox within a datagrid on PageLoad? If so, how?
Have another question, is it possible to have a TEXTCHANGED method
for a textbox within the datagrid. Once again, how?
I am trying to figure out whether I should continue on searching on
how to do thing in a datagrid or just switch to something else. I
can't seem to find solutions for those quations.
THANKS

Hi all,
I am trying to make a UserControl with a TextBox in it.
I have to publish the TextChanged event of the inner TextBox, but I have
some trouble.
If I declare :
public event EventHandler TextChanged;
I get a compiler error saying that TextChanged is already declared and I
have to use :
public new event EventHandler TextChanged;

I used the textchanged event of textbox and set the autopostback property to
true. The textchanged event should fire when the content of the textbox is
changed and user tab out of the textbox control. However, textchanged event
fires whenever there is a postback, even when I click a button that send
postback. Can anybody tell we what change I should make so that textchanged
event only fire when the content is changed?

Hey guys,
I have 2 events on a windows forms datagrid, the mouse move as well as the
double click events.
What's happening is that when I double click on a row in the grid, the mouse
move event gets triggered and the double click is not identified at all.
Is there any way I can invoke the double click when the mouse move also
exists?

Hi,
In my C# Windows form MyForm I have some TextBoxes.
In these TextBoxes, we have to detect if the TextChanged event occurs,
if there're changes in these TextBoxes, it will ask if we want to save the
changes when we close the form.
However, when I run the MyForm, it will fetch data from the system and put
into TextBoxes,
and this incurs the textchanged event.
But I am thinking how do I make the TextBox's TextChanged know the

The original problem was creating a user control and trying to use existing event types like "TextChanged", if you were creating a control that was similar to a text box, for example.
The problem was that the developers at Microsoft decided that this...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
