Paging not working

[Appu]

Hi
 I hav one problem for my Radgrid paging..

        while calling the below code the paging or page index changed does not working. As a result i cannot move to next page from my first page displayed as well.

My code snipper is below:
 protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
      RefreshCombos();
      
    }

    //To refresh the resultset
    private void RefreshCombos()
    {
        objDA= new ClassDA();
        DataTable dt= objDA.GetDetails();

        RadGrid1.DataSource =dt;
        RadGrid1.MasterTableView.Rebind();
        
    }

I am used the code what ever it is given by the Telerik help page for filtering controls. But it is not working fine while page moving

Thanks
Appu

Hi Appu,

If you are using inbuilt Paging you do not need to Rebind the Grid in the PreRender event. When you rebind the Grid on each and every PostBack the CurrentPageIndex of the Grid will be set to the first page.

Hi Appu,

Are you trying to implement basic Filtering? If so you just need to bind the Grid using AdvanceDataBinding techniques.

Hi

   I am not using basic filtering instead of i am using the below code

 string filterExpression = "";

        if (e.Value != "All")
        {
            filterExpression = "([Firm_name] = '" + e.Value + "')";
        }
        else
        {
            filterExpression = "([Firm_name] <> '')";
        }

         RadGrid1.MasterTableView.FilterExpression = filterExpression;
      
once ofter the above code is over i cal RefreshCombo function

//To refresh the resultset
    private void Refresh()
    {

        objDataAccess = new DataAccess();
        contactsTable = objDataAccess.GetContacts();

        RadGrid1.DataSource = contactsTable;
        RadGrid1.MasterTableView.Rebind();
        
        
    }

This all done for my filtering. But i am facing the problem in my tradional grouping and paging. Soon after the filtering is over..

Hope u could understand

Hello Appu,

You don't need to set the filtering expression on every postback because this resets the page index. This way you can't reach the second page at all (as already mentioned by Shinu).
