Hello,
I have a callback panel with a seies of textbox.
When a change a value of a textbox I would create a trigger for callback panel to execute the sum of all text box.
how can I triggering a callback with a textbox change?
thanks
Andrea

Hi,

In order for a control to trigger a Callback, you need to:

1. Make sure the control to raise a server side event;
2. Set the control as a trigger of the CallbackPanel;

In the case of a TextBox, you would set its AutoPostBack to true in order to satisfy #1.

Hope this helps.

Thanks
