Exception Details: System.Web.HttpException: The GridView 'GridView1' fired event PageIndexChanging which wasn't handled.

Answer 1

You have to handle the PageIndexChanging event, if you click the grid on the designer and look at the events, double click on the PageIndexChanging event, if you don't need to cancel or do anything special, just rebind the data in the handler

Answer 2

You Should just add the namespace

using System.Collections.Generic;

and write this code only

public void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    BindGridview();
}

it 100% works try it......

Answer 3

You have to provide an event handler for PageIndexChanging, which is where you provide the paging logic.

Answer 4

write like this in GridView1_PageIndexChanging event:

GridView1.PageIndex = e.NewPageIndex;

then again bind the grid. ur prob will solve.
