Hello!

I add RadPanelItems dynamic and also adding CheckBoxes to each.
How do loop through all RadPanelItems and find CheckBoxes and get there state?

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">

<head runat="server">

    <title></title>

</head>

<body>

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

    <div>

        <telerik:RadScriptManager ID="RadScriptManager1" runat="server">

            <Scripts>

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

                </asp:ScriptReference>

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

        </telerik:RadScriptManager>



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

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

        End If

    Next

End Sub

Hope that this will lead you into the right direction.

Kind regards,
