Cannot find controls inside ItemTemplate of RadPanelBar

[Covertix]

Hi

I have a RadPanelBar, and I can't find controls inside the ItemTemplate.
I read:Help documentation for accessing item: Accessing Items
Help documentation for accessing control inside: Accessing Controls Inside Templates
But it doesn't work for me.

here is my code:

 

<telerik:RadPanelBar ID="rpbAddFilters" runat="server">

    <Items>

        <telerik:RadPanelItem Text="RadPanelItem" runat="server">

            <Items>

                <telerik:RadPanelItem Value="test" runat="server">

                    <ItemTemplate>

                        <telerik:RadCodeBlock ID="RadCodeBlock2" runat="server">

 

                                        <asp:Panel ID="pnlValues" runat="server">

 

                                `       </asp:Panel>

                        </telerik:RadCodeBlock>

                  </ItemTemplate> 
                </telerik:RadPanelItem >
            </Items>
         </telerik:RadPanelItem >
    </Items>
</RadPanelBar>

 

 

function find()
{

    var panelbar = $find("<%= rpbAddFilters.ClientID %>");

 

  

    var item = panelbar.findItemByValue("test");

    var pnlValues = item.findControl("pnlValues");

}



I get null value for pnlValues.


Thanks.

Ok i dont have an Example for javascript but i cant show you how you can do it on the server side. So in my case i have a "ReportViewer" inside the item so the following code finds the REportviewer inside an itemtemplate

Dim RadPanelBar1 As RadPanelBar = CType(sender, RadPanelBar)
                Dim InnerPanel As RadPanelItem = CType(RadPanelBar1.FindItemByValue("Impairment"), RadPanelItem)
                Dim rptreportviewer As Microsoft.Reporting.WebForms.ReportViewer = CType(InnerPanel.FindControl("rptImpairment"), Microsoft.Reporting.WebForms.ReportViewer)

             So look at the Value option, i use that to find the control inside the ItemTemplate 

  <telerik:RadPanelBar ID="RadPanelBar1" runat="server" ExpandMode="FullExpandedItem"
      Height="500px" Skin="Hay" Width="862px">
      <Items>
<telerik:RadPanelItem    Text="Impairment">
              <Items>
                  <telerik:RadPanelItem Value="Impairment">
                      <ItemTemplate>
                          <rsweb:ReportViewer Width="100%" Height="500px" ID="rptImpairment" runat="server">
                          </rsweb:ReportViewer>
                      </ItemTemplate>
                  </telerik:RadPanelItem>
              </Items>
          </telerik:RadPanelItem>
      </Items>
  </telerik:RadPanelBar>

Hi Tzach,

To access nested controls client-side, you need to be sure that the control in question has a client  side object. Most Telerik RadControls for ASP.NET AJAX have a client object, but the standard ASP Panel does not have a client object hence the error that you have experienced.

All the best,
