Hello Omar,

Here's a sample code snippet that shows the needed approach.

<form id="form1" runat="server">
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
    </telerik:RadScriptManager>
    <telerik:RadPanelBar ID="RadPanelBar1" runat="server">
        <Items>
            <telerik:RadPanelItem runat="server" Text="Root RadPanelItem1">
                <Items>
                    <telerik:RadPanelItem runat="server" Value="templateHolder">
                        <ItemTemplate>
                            <asp:CheckBox ID="CheckBox2" runat="server" />
                        </ItemTemplate>
                    </telerik:RadPanelItem>
                </Items>
            </telerik:RadPanelItem>
        </Items>
    </telerik:RadPanelBar>
    <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    </form>

using System;
using System.Collections.Generic;

public partial class _Default : System.Web.UI.Page

    {

    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        CheckBox cb = (CheckBox)RadPanelBar1.FindItemByValue("templateHolder").FindControl("CheckBox2");
        Label1.Text = cb.Checked.ToString();
    }
}

Hello Omar,

There you go:

ASPX:

    <form id="form1" runat="server">
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
    </telerik:RadScriptManager>
    <telerik:RadPanelBar ID="RadPanelBar1" runat="server">
        <Items>
            <telerik:RadPanelItem runat="server" Text="Root RadPanelItem1">
                <Items>
                    <telerik:RadPanelItem runat="server" Value="templateHolder">
                        <ItemTemplate>
                            <asp:CheckBox ID="CheckBox2" runat="server" />
                        </ItemTemplate>
                    </telerik:RadPanelItem>
                </Items>
            </telerik:RadPanelItem>
        </Items>
    </telerik:RadPanelBar>
    <asp:Button ID="Button1" runat="server" Text="get" OnClick="Button1_Click" />
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    <asp:Button ID="Button2" runat="server" Text="set" OnClick="Button2_Click" />
    </form>

Code-behind:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        CheckBox cb = (CheckBox)RadPanelBar1.FindItemByValue("templateHolder").FindControl("CheckBox2");
        Label1.Text = cb.Checked.ToString();
    }
    protected void Button2_Click(object sender, EventArgs e)
    {
        CheckBox cb = (CheckBox)RadPanelBar1.FindItemByValue("templateHolder").FindControl("CheckBox2");
        cb.Checked = !cb.Checked;
    }
}
