checkbox list inside an itemtemplate for radmenu

[KevinMc]

I am trying to add a checkbox list to an itemtemplate for the radmenu. It binds fine but when the page displays the menu item with the checkbox lists is displayed and does not expand collapse.

<telerik:RadMenuItem runat="server" Text="Marketing">
            <ItemTemplate>
                <div id="MarketingTemplate">
                    <div>
                        Species<asp:CheckBoxList ID="CheckBoxList1" runat="server" DataSourceID="odsSpecies"
                            DataTextField="Name" DataValueField="Name">
                        </asp:CheckBoxList>
                        <asp:ObjectDataSource ID="odsSpecies" runat="server" OldValuesParameterFormatString="original_{0}"
                            SelectMethod="GetSpeciesList" TypeName="Adisseo.Modules.DocumentManagement.KeywordManager">
                        </asp:ObjectDataSource>
                    </div>
                    <div>
                        Feed Type<asp:CheckBoxList ID="CheckBoxList2" runat="server" DataSourceID="odsFeedTypes"
                            DataTextField="Name" DataValueField="Name">
                        </asp:CheckBoxList>
                        <asp:ObjectDataSource ID="odsFeedTypes" runat="server" OldValuesParameterFormatString="original_{0}"
                            SelectMethod="GetFeedTypeList" TypeName="Adisseo.Modules.DocumentManagement.KeywordManager">
                        </asp:ObjectDataSource>
                    </div>
                </div>
            </ItemTemplate>
        </telerik:RadMenuItem>

Hi KevinMc,

Thank you for contacting us.

When you use templates as in your code, you apply the template to RadMenuItem with text "Marketing". If you want to apply a template to its child, use the following approach:

<telerik:RadMenuItem runat="server" Text="Marketing">
                        <Items>
                            <telerik:RadMenuItem runat="server">
                                <ItemTemplate>
                                    <div id="MarketingTemplate">
                                        <div>
                                            Species<asp:CheckBoxList ID="CheckBoxList1" runat="server" DataSourceID="odsSpecies"
                                                DataTextField="Name" DataValueField="Name">
                                            </asp:CheckBoxList>
                                            <asp:ObjectDataSource ID="odsSpecies" runat="server" OldValuesParameterFormatString="original_{0}"
                                                SelectMethod="GetSpeciesList" TypeName="Adisseo.Modules.DocumentManagement.KeywordManager">
                                            </asp:ObjectDataSource>
                                        </div>
                                        <div>
                                            Feed Type<asp:CheckBoxList ID="CheckBoxList2" runat="server" DataSourceID="odsFeedTypes"
                                                DataTextField="Name" DataValueField="Name">
                                            </asp:CheckBoxList>
                                            <asp:ObjectDataSource ID="odsFeedTypes" runat="server" OldValuesParameterFormatString="original_{0}"
                                                SelectMethod="GetFeedTypeList" TypeName="Adisseo.Modules.DocumentManagement.KeywordManager">
                                            </asp:ObjectDataSource>
                                        </div>
                                    </div>
                                </ItemTemplate>
                            </telerik:RadMenuItem>
                        </Items>
                    </telerik:RadMenuItem>

Hope this helps.

Hi Muhammad Nasir,

Please take a look into this help article which discuss about add templates to RadMenu at runtime, using the ItemTemplate property. Let me know if you have any concern.

Thanks,

Unable to cast object of type 'Telerik.Web.UI.RadSearchBox' to type 'System.Web.UI.ITemplate'.

And here is my code

RadMenu1.ItemTemplate = New RadSearchBox()

Hi Muhammad Nasir,

Please try the below C# code snippet which works fine at my end.

C#:

protected override void OnInit(EventArgs e)
{
    RadMenu1.ItemTemplate = new SearchBoxTemplate();
    base.OnInit(e);
}
class SearchBoxTemplate : ITemplate
{
    public void InstantiateIn(Control container)
    {
        RadSearchBox searchBox = new RadSearchBox();
        searchBox.ID = "rsearchItems";
        container.Controls.Add(searchBox);
        Label label1 = new Label();
        label1.ID = "lblItems";
        label1.Text = "Text";
        label1.DataBinding += new EventHandler(label1_DataBinding);
        container.Controls.Add(label1);
    }
    private void label1_DataBinding(object sender, EventArgs e)
    {
        Label target = (Label)sender;
        RadMenuItem item = (RadMenuItem)target.BindingContainer;
        string itemText = (string)DataBinder.Eval(item, "Text");
        target.Text = itemText;
    }
}

Thanks,
Shinu.
