When I click the page number then error is

The GridView 'GridView1' fired event PageIndexChanging which wasn't handled.
How to handle it?
When I try
this

C#

protected void GridView2_SelectedIndexChanged(object sender, EventArgs e)
        {
            GridView1.PageIndex = e.NewPageIndex;
            GridView1.DataSource = GetData();
            GridView1.DataBind();
        }

during the build error is
'System.EventArgs' does not contain a definition for 'NewPageIndex' and no extension method 'NewPageIndex' accepting a first argument of type 'System.EventArgs' could be found (are you missing a using directive or an assembly reference?)

Solution 58

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
// Set the new page index
GridView1.PageIndex = e.NewPageIndex;

// Rebind the GridView with the updated page index
BindGridView(); // Implement this method to bind data to the GridView

// Optionally, cancel the default behavior by setting e.Cancel to true
e.Cancel = true;
}

Solution 1

You need to handle the PageIndexChanging event for the grid like

C#

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    //Bind grid

}

To use paging in GridView you need to take care of following things
1. Give PageSize
2. write PageIndexChanging event
You have not define GridView1_PageIndexChanging in your codebehind
check following code

C#

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    //Bind grid
}
