There a property AutoPostBack="True". Just use this. I think it will solve your problem.

let the code be:

<asp:button ID="btn2" runat="server" AutoPostBack="True" Text="Delete Selected"
onclick="btn2_Click" />

Hi,

Please add a property AutoPostBack="true" and then check.

Autopostback is the mechanism, by which the page will be posted back to the server automatically based on some events in the web controls. In some of the web controls, the property called auto post back.

If it is set to true,it will send the request to the server when an event happens in the control.

Whenever we set autopostback attribute to true in any of the controls, the .net framework will automatically insert few code in to the HTML generated to implement this functionality.

1.) A Java script method with name __doPostBack (eventtarget, eventargument)
2.) Two Hidden variables with name __EVENTTARGET and __EVENTARGUMENT
3.) OnChange JavaScript event to the control

Hope this helps :)

Regards,
Praneet
