Hi You are making linkbuttons visibility to false in postback condition. Comment out those lines only. Call only the method to bind dropdown inside postback block.

As per code it should work properly. Is there any javascript code which makes impact on button event fire. Please cross that. Here is some sample code: false runat= server ID= grdCustomPagging > RowNumber HeaderText= RowNumber /> View > server ID= lnkView OnClick= lnkView_Click >View Order protected void lnkView_Click( object sender EventArgs e) { GridViewRow grdrow = (GridViewRow)((LinkButton)sender).NamingContainer; } For cross check can you create another button and add click event. See whether event fires. If it doesn't fire the event then restart the Visual Studio and make mode Debug.

Hi You are using updatepanel in your pages. For button clicks to work inside update panel you have to use triggers. Just make your update panel as below - ChildrenAsTriggers=true> Now add below line just after Closing Just go through below links to understand about triggers & updatepanel - http://www.asp.net/web-forms/overview/older-versions-getting-started/aspnet-ajax/understanding-asp-net-ajax-updatepanel-triggers http://www.aspdotnet-suresh.com/2012/05/ajax-updapanel-control-with-triggers.html http://www.aspsnippets.com/Articles/Assign-PostBack-Trigger-Full-PostBack-for-LinkButton-inside-GridView-within-AJAX-UpdatePanel-in-ASPNet.aspx
