Hello Anders,

Could you please elaborate a bit more on your scenario so we can test it locally?

Could you provide some information about which templates in your project you are using? Here you can find more information about templates in RadPanelBar control.
Providing a sample project that demonstrates your scenario (the declaration of the templates and the way you apply them) would be really helpful.

Any additional information will be highly appreciated.

Thanks for your reply.
I want to read the values of all the checkboxes in one postback.
Here is an example:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Test_statisk.aspx.vb" Inherits="Test_statisk" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<body>

<form id="form1" runat="server">

<div>

</asp:ScriptReference>

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js">

</asp:ScriptReference>

</Scripts>

</telerik:RadScriptManager>

<telerik:RadPanelBar ID="radPanelBar" Runat="server" style="margin-right: 117px" Width="353px">

<Items>

<telerik:RadPanelItem runat="server" Text="Main 1">

</body>

</html>

Imports Telerik.Web.UI

Partial Class Test_statisk

Inherits System.Web.UI.Page

Protected Sub btnShowSelected_Click(sender As Object, e As EventArgs) Handles btnShowSelected.Click

For Each c As RadPanelItem In radPanelBar.GetAllItems

For Each x As Control In c.Items

lblText.Text &= x.GetType.ToString & "<br>" ' this only returns "Telerik.Web.UI.RadPanelItem"

Next

End Sub

End Class

Hello Anders,

Please note that your last two CheckBox ID are duplicating the CheckBox ID in the first RadPanelBar.
Their ID values should be as following - cb31 and cb32.
Please use the following approach to achieve the desired functionality:

Protected Sub btnShowSelected_Click(sender As Object, e As EventArgs) Handles btnShowSelected.Click

Dim panels As IList(Of RadPanelItem) = radPanelBar.GetAllItems()

For Each panel As RadPanelItem In panels

If panel.Items.Count = 0 Then

Dim checkBox As CheckBox = TryCast(panel.Controls(1), CheckBox)

If checkBox.Checked = True Then

lblText.Text += checkBox.ID

End If

Next

End Sub

Hope that this will lead you into the right direction.

Kind regards,
