Hello everybody
I have a problem with textbox. I'm initializing a textbox in page load
but every time I change the textbox and Text Changed is fired the text
turned beck to the original value and show the old value instead the
new one
How can I solve it?

Click to expand...

Page_Load is called every time the page is requested from the server:
on initial access plus on postbacks!
You need to check "IsPostBack" to skip assigning on postback.

Assign the value to the text box only if its not a postback.

if (!IsPostBack)
{
txt.Text = <value>;
}
