i think text change only fires on keybord events....

I guess only because there is no a way to change a text only with a mouse... :-)
It does not help to solve the problem. However... unless OP failed to see that the event is actually fired. Such things happen.

laugh... I thought he meant when he change the text in code... I dont think they fire at that event

We can change the text with mouse using OSK ;)

This is what I say. This issue is unrelated to this problem...

Yes :) Agreed.

Empty handler method? How did you make sure it really did not fire? Also, did you check up under debugger if += operator (adding an event handler to the event instance's invocation list) was actually executed before?

Solution 1

You have to specify the AutoPostBack property of the text box to true.

In aspx,

C#

<asp:textbox id="txtTest" autopostback="true" runat="server" ontextchanged="txtTest_Changed" xmlns:asp="#unknown"></asp:textbox>

In code-behind,

C#

protected void txtTest_Changed(object sender, EventArgs e)
{
    // your code goes here
}
