"Erro de runtime de JavaScript: Sys.WebForms.PageRequestManagerServerErrorException: The GridView 'GridView1' fired event RowDeleting which wasn't handled"

btw, im pretty new with asp, javascript ... be patient with me and help me pls

You have no handler for the RowDeleting event.

This is c#, but you can convert it ...

<asp:GridView ID="GridView1" runat="server" 

 protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)


His error ...

'GridView1' fired event RowDeleting which wasn't handled

... or am I missing something?

Probably he has an event declared in the ASP/HTML code with no corresponding function in the code behind.
