onkeyup event asp.net

Question

Hi how can i register and call a server side event for onkeyup event in asp.net textbox.

Is it possible?

thank you

Answer 1

TextBox Web control doesn't provide onkeyXXX events instead subscribe to OnTextChanged event;

    

public void HandleTextbox1OnTextChanged(Object sender, EventArgs e)
    {

    }

But you can provide onkeyXXX behavior from client-side.

You can add client-side handler like :

Textbox1.Attributes.Add("onkeyup", String.Format("onKeyUp({0})", TextBox1.ID));

And in the page

``

Also you could use PageMethods to make a call to server-side web methods (static methods) from javascript functions.
