paging issue in Radgrid.

[Srikar]

Hi,

I have enabled paging in the "grdReportDataGrid" grid. Which is inside "RadGrid1" grid. When i navigating between "grdReportDataGrid" pages, "RadGrid1" is collapsing.

Expected output: "RadGrid1" should not collapse and user should see the request page in “grdReportDataGrid”

Here is the designer file.

Hi Srikar,

I guess you wan to keep the RadGrid1 expanded.Please try adding the following code snippet with your ItemCommand.

C#:

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.ExpandCollapseCommandName)
    {
        foreach (GridDataItem item1 in RadGrid1.MasterTableView.Items)
        {
            if (item1.Expanded == true)
            {
                item1.Expanded = true;
            }
        }
        GridDataItem item = e.Item as GridDataItem;
        RadGrid RadGrid3 = (item.ChildItem as GridNestedViewItem).FindControl("RadGrid3") as RadGrid;
        dynamic data = new[]
     {
        new { ID = 1, Name ="Naaaame1"},
        new { ID = 2, Name = "Naaaame2"},
        new { ID = 3, Name = "Naaaame3"},
        new { ID = 4, Name = "Naaaame4"},
        new { ID = 5, Name = "Namaaae5"}
     };
        RadGrid3.DataSource = data;
        RadGrid3.DataBind();
    }
}

Thanks,

Hello,

Please try with below code snippet.

protected void grdReportDataGrid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
   {
       GridNestedViewItem item = ((sender as RadGrid).NamingContainer as GridNestedViewItem); // Access Cuurernt Nesttedview

       GridDataItem pitem = item.ParentItem as GridDataItem; // access parent ROw

       dynamic data = new[] {
       new { ID = 1, Name ="Naaaame1"},
       new { ID = 2, Name = "Naaaame2"},
       new { ID = 3, Name = "Naaaame3"},
        new { ID = 4, Name = "Naaaame4"},
       new { ID = 5, Name = "Namaaae5"},
       new { ID = 26, Name = "Naaaame26"}
   };

       (sender as RadGrid).DataSource = data;

   }


   protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
   {
       if (e.CommandName == RadGrid.ExpandCollapseCommandName)
       {
           GridDataItem item = e.Item as GridDataItem;
           RadGrid grdReportDataGrid = (item.ChildItem as GridNestedViewItem).FindControl("grdReportDataGrid") as RadGrid;

           grdReportDataGrid.Rebind();
       }
   }


   protected void mainTab_TabClick(object sender, RadTabStripEventArgs e)
   {

       dynamic data = new[] {
       new { ID = 1, Name ="Name1"},
       new { ID = 2, Name = "Name2"},
       new { ID = 3, Name = "Name3"},
        new { ID = 4, Name = "Name4"},
       new { ID = 5, Name = "Name5"},
       new { ID = 26, Name = "Name26"}
   };

       RadGrid1.DataSource = data;
       RadGrid1.DataBind();
   }
