I want to call Textbox.OnTextChange event without having to click a submit button or any button. How can I do this? As I enter text in the textbox, I want the ontextchange event to fire.

I would elaborate this further.I’ve a function for validating my entry in textbox which I’m calling ontextchange property.Now this function should be called without me changing focus from my textbox.

You can use onkeypress , onkeyup and onkeydown events for this.

Example :

  <asp:TextBox ID="TextBox1" runat="server" onKeyPress="javascript:alert('Key Pressed');"></asp:TextBox>
