Hi Manuel,

Please try the below sample code snippet to access a radgrid in nestedview template.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource"
    AllowPaging="true" OnItemCommand="RadGrid1_ItemCommand">
    <MasterTableView DataKeyNames="CustomerID">
        <NestedViewTemplate>
            <asp:Panel runat="server" ID="Panel1" Visible="true">
                <telerik:RadTabStrip runat="server" ID="TabStrip1" MultiPageID="Multipage1" SelectedIndex="0">
                    <Tabs>
                        <telerik:RadTab runat="server" Text="Page 1" PageViewID="PageView1">
                        </telerik:RadTab>
                    </Tabs>
                </telerik:RadTabStrip>
                <telerik:RadMultiPage runat="server" ID="Multipage1" SelectedIndex="0" RenderSelectedPageOnly="false">
                    <telerik:RadPageView runat="server" ID="PageView1">
                        <telerik:RadGrid ID="RadGrid2" runat="server" AllowPaging="true" PageSize="5" OnNeedDataSource="RadGrid2_NeedDataSource" />
                    </telerik:RadPageView>
                </telerik:RadMultiPage>
            </asp:Panel>
        </NestedViewTemplate>
    </MasterTableView>
</telerik:RadGrid>

C#:

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
  {
      RadGrid1.DataSource = GetDataTable("SELECT CustomerID, CompanyName, ContactTitle FROM Customers");
  }
  protected void RadGrid2_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
  {
      GridDataItem parentItem = ((sender as RadGrid).NamingContainer as GridNestedViewItem).ParentItem as GridDataItem;
      (sender as RadGrid).DataSource = GetDataTable("SELECT OrderID, EmployeeID, CustomerID FROM Orders where CustomerID='" + parentItem.GetDataKeyValue("CustomerID").ToString() + "'");
  }
  protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
  {
      if (e.CommandName == RadGrid.ExpandCollapseCommandName && !e.Item.Expanded)
      {
          GridDataItem parentItem = e.Item as GridDataItem;
          RadGrid grid = parentItem.ChildItem.FindControl("RadGrid2") as RadGrid;
          grid.Rebind();
      }
  }

Thanks,

Thank you very much that worked for me :)

Now i have another problem.
as i said before, i have a grid. In this grid there are a radmultipage with radtabs. In the radtabs there are 6 Radgrids for each of my six tabs.
No i want the radgrid to resizetofit, but it doesn´t worked.

Here´s my code snippet from the resize method:

<%--    <script>
                  function pageLoad() {
                      var grid = $find("RadGrid2");
                      var columns = grid.get_masterTableView().get_columns();
                      for (var i = 0; i < columns.length; i++) {
                          columns[i].resizeToFit();
                      }

                          var grid = $find("RadGrid3");
                          var columns = grid.get_masterTableView().get_columns();
                          for (var i = 0; i < columns.length; i++) {
                              columns[i].resizeToFit();
                          }
                              var grid = $find("RadGrid4");
                              var columns = grid.get_masterTableView().get_columns();
                              for (var i = 0; i < columns.length; i++) {
                                  columns[i].resizeToFit();
                              }
                                  var grid = $find("RadGrid5");
                                  var columns = grid.get_masterTableView().get_columns();
                                  for (var i = 0; i < columns.length; i++) {
                                      columns[i].resizeToFit();
                      }
                              }

              </script>--%>

Hi Manuel,

Please try the following code snippet.The issue is in this line  "$find("RadGrid2")". Please correct the code as below and check if the issue persists.

ASPX:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        function pageLoad() {
            var grid = $find("<%= RadGrid2.ClientID %>");
            var columns = grid.get_masterTableView().get_columns();
            for (var i = 0; i < columns.length; i++) {
                columns[i].resizeToFit();
            }
        }
    </script>
</telerik:RadCodeBlock>

Let me know if any concern.

Thanks,
Princy

 Thank you very much, but unfortunately it doesnt work because Radgrid2 is not defined.
 To access the radgrid2 i have the following code:

Dim ChildGrid2 As New RadGrid

Dim nestedItem As GridNestedViewItem = DirectCast(source.mastertableview.items(e.Item.ItemIndex).ChildItem, GridNestedViewItem)
             ChildGrid2 = DirectCast(nestedItem.FindControl("RadGrid2"), RadGrid)
                ChildGrid2.AutoGenerateColumns = True

The Radgrid2 is within a Radpageview, so i have to navigate to the radgrid2

[Princy]

Hi Manuel,

You can resize the child grid by setting the resize method in OnGridCreated event of the Child RadGrid.Please try the below code snippet.

ASPX:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
           <script type="text/javascript">
               //For ParentGrid RadGrid1
               function pageLoad() {
                   var grid = $find("<%= RadGrid1.ClientID %>");
                   var columns = grid.get_masterTableView().get_columns();
                   for (var i = 0; i < columns.length; i++) {
                       columns[i].resizeToFit();
                   }
               }
               //For ChildGrid RadGrid2
               function GridCreated(sender, args) {
                   var grid = sender;
                   var columns = grid.get_masterTableView().get_columns();
                   for (var i = 0; i < columns.length; i++) {
                       columns[i].resizeToFit();
                   }
               }
           </script>

How to update the Tab.Text with some value, from Ajax on Client ( by javascript or jquery )  through Radgrid->NestedViewTemplate->RadTabStrip ?

<script>

function HierarchyExpanding(sender, args) {
   var ROWNUM= args.getDataKeyValue("ROWNUM");
         $.ajax({
          type: "POST",
          contentType: "application/json; charset=utf-8",
          url: "WebServices/GetData.asmx/getCountToParentisize",
 data: "{'ROWNUM':'" + ROWNUM+ "'}",

      ?????????    How update Tab.Text from here ??????            },

Hi Anatoly,

 

The RadTab client-side object provides the set_text and set_value methods you can use to achieve this requirement:
https://docs.telerik.com/devtools/aspnet-ajax/controls/tabstrip/client-side-programming/objects/radtab-object

First, you will need to access the RadTabStrip control using the findControl method:
https://www.telerik.com/support/kb/aspnet-ajax/details/access-telerik-controls-on-client-side

Then, you can get the tab you want.

Finally, you can change its text using the set_text(...) method.

I hope this will prove helpful.

Eyup
