web user control in RadPanelBar not being created

[Mark Bennett]

Hi,

At the moment im swapping over an Ajax accordion to a RadPanel bar, however it doesnt create the user control when its inside the panelbar, but when its outside of it, it works fine, the user control is not ajax.

my code looks like this

    <telerik:RadPanelBar
    ID="radAccordionSheepSales"
    runat="server"
    ExpandMode="SingleExpandedItem">
        <Items>
            <telerik:RadPanelItem runat="server" Text="Sheep Sales">
            <ItemTemplate>
                <table class="SheepSales_Table">
                    <tr>
                        <td>
                            <uc1:ucSheepSales ID="ucSheepSales1" runat="server" />
                        </td>
                        <td>
                            <asp:LinkButton ID="btnAdd" runat="server" SkinID="SheepSales_BtnAdd">Add</asp:LinkButton>
                        </td>
                    </tr>
                    <tr>
                        <td>
                            <div id="scrollDiv" class="SheepSales_Placeholder">
                                <asp:UpdatePanel ID="SheepSales_UpdateContainer" runat="server">
                                    <ContentTemplate>
                                        <asp:PlaceHolder ID="phSheepSales" runat="server"></asp:PlaceHolder>
                                    </ContentTemplate>
                                </asp:UpdatePanel>
                            </div>
                        </td>
                        <td>
                        </td>
                    </tr>
                </table>
            </ItemTemplate>
            </telerik:RadPanelItem>

            <telerik:RadPanelItem runat="server" Text="Sheep Kills">
            <ItemTemplate>
                    <asp:PlaceHolder ID="phKills" runat="server">
                    <uc2:ucSheep ID="ucSheep1" runat="server" DisplayMode="Header" />
                    </asp:PlaceHolder>
            </ItemTemplate>
            </telerik:RadPanelItem>
        </Items>
    </telerik:RadPanelBar>

Hello Mark,

Could you please add the user controls to the first level items (not root items) like this:

<telerik:RadPanelItem runat="server" Text="Sheep Sales">
    <Items>
        <telerik:RadPanelItem Text="">
            <ItemTemplate>
                <table class="SheepSales_Table">
                    <tr>
                        <td>
                           <uc1:ucSheepSales ID="ucSheepSales1" runat="server" />
                        </td>
                        <td>
                            <asp:LinkButton ID="btnAdd" runat="server" SkinID="SheepSales_BtnAdd">Add</asp:LinkButton>
                        </td>
                    </tr>
                    <tr>
                        <td>
                            <div id="scrollDiv" class="SheepSales_Placeholder">
                                <asp:UpdatePanel ID="SheepSales_UpdateContainer" runat="server">
                                    <ContentTemplate>
                                        <asp:PlaceHolder ID="phSheepSales" runat="server"></asp:PlaceHolder>
                                    </ContentTemplate>
                                </asp:UpdatePanel>
                            </div>
                        </td>
                        <td>
                        </td>
                    </tr>
                </table>
            </ItemTemplate>
        </telerik:RadPanelItem>
    </Items>
</telerik:RadPanelItem>

and let us know how it goes.

Hey Yana,

sorry the solution didnt work, the objects in the designer (when they are inside the radpanelbar) are failing to be initialised when the page is accessed, and so when i try to access them in the code behind(vb) file, they are null references :(

[Mark Bennett]

actually, ive noticed that when i use your solution, i cant even access them in the code behind file, as if their runat="server" property was not there(but it is)

Hi Mark Bennett,

I'm sorry for the delayed reply.

I've attached a simple page demonstrating that user control is working inside RadPanelBar template, please download the file and give it a try.

Hi Yana,

i tried your code in the project (exactly the same) and i still cant access the usercontrol in the code behind file :( i can see the panelbar and the sheepsales panelbaritem in the designer but no user control or any place holders or content

Hello Mark,

This is really strange, which version of the controls you are using?

Hello Mark Bennett,

Try this code in my sample to access ucSheepSales1 control:

UserControl ctrl = (UserControl)RadPanelBar1.FindItemByText("Sheep Sales").Items[0].FindControl("ucSheepSales1");

All the best,
