Hello NanthaKumar,

One option is you can temporarily disabling the paging, rebind the grid and retrieve all the items. After getting all the item, you can re-enable the paging for grid.

C#:

protected void GRD_NewsList_PreRender(object sender, EventArgs e)
   {
       GRD_NewsList.AllowPaging = false;
       GRD_NewsList.Rebind();
       foreach (GridDataItem item in GRD_NewsList.Items)
       {
           string key = item.GetDataKeyValue("NewsId").ToString();
       }
       GRD_NewsList.AllowPaging = true;
       GRD_NewsList.Rebind();
   }

    For Each Items As GridDataItem In GRD_NewsList.MasterTableView.Items
        If GetNumeric(Items.GetDataKeyValue("NewsId")) = val Then
            Items.Edit = True
            Exit For
        End If
    Next

    GRD_NewsList.MasterTableView.AllowPaging = True
