Hi Experts,
I have a major issue in ASP.net2.0. I had written a code for PageIndexChanged event in .net .1.1. That worked fine. But when I ported the same code to .net 2.0, the event is not getting fired at all. Can anyone help me on this

can you please share your code so that we can have a look and give you a solution
just telling us that something is not working without any code snipped does not make it easy for us to even suggest anything

Add the following attribute for gridview in .aspx file:----->

OnSelectedIndexChanged="grdView1_SelectedIndexChanged"

Now, use the following code:----->

protected void grdView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        grdView1.PageIndex = e.NewPageIndex;
        BindGrid(); // Write this function for binding gridView.
    }

the code has been migrated from 1.1 framework to 2.0 framework
how can the gridview be there -- the author will be using the datagrid as after migration the control is not changed for backward compatibality and migrated code.

Please share your code so that we can have a look at it and try to help you better

Correction on previous answer:
==================

Add the following attribute for gridview in .aspx file:

OnPageIndexChanging="grdItems_PageIndexChanging"

Now, use the following code:----->

protected void grdView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        grdView1.PageIndex = e.NewPageIndex;
        BindGrid(); // Write this function for binding gridView.
    }

I have added the code snippet for the same.

I have also added OnPageIndexChanged event in .aspx page. I dont have a GridView. Instead I have a DataGrid. I have directly ported from .net1.1 to .net 2.0
<asp:DataGrid id="MyGrid"    OnPageIndexChanged="dgrid_PageIndexChanged">

protected void dgrid_PageIndexChanged(object source, DataGridPageChangedEventArgs e)
        {
            try
            {
                dtgJournal.CurrentPageIndex = e.NewPageIndex;                
 
		//To Store the journal grid visible columns in to the hashtable for sorting purpose.
                colHeaderMap = new Hashtable();
		int idx = 0;
		foreach (DataGridColumn col in dtgJournal.Columns)
		{
			colHeaderMap[col.SortExpression] = idx++;
		}
                
//		Getting Visible Columns and Binding the Journal Data to the Grid.
                BindUIToDataSet(emailsDataSet);//Binds the DS
            }//try
            catch (Exception)
            {
            }//catch
        //}
        }

The code snippet
protected void dgrid_PageIndexChanged(object source, DataGridPageChangedEventArgs e)
        {
            try
            {
                dgrid.CurrentPageIndex = e.NewPageIndex;                
 
		//To Store the journal grid visible columns in to the hashtable for sorting purpose.
                colHeaderMap = new Hashtable();
		int idx = 0;
		foreach (DataGridColumn col in dtgJournal.Columns)
		{
			colHeaderMap[col.SortExpression] = idx++;
		}
                
//		Getting Visible Columns and Binding the Journal Data to the Grid.
                BindUIToDataSet(emailsDataSet);//Binds the DS
            }//try
            catch (Exception)
            {
            }//catch
        //}
        }

try to register the event manually

// Manually register the event-handling method for the PageIndexChanged  
// event of the DataGrid control.
dgrid.PageIndexChanged += new DataGridPageChangedEventHandler(this.dgrid_PageIndexChanged);
