How to set the SelectedItem in C#

[Frank]

I am trying to selected the PanelBar item when user click on the button. I do not understand why I am not able to set the selecteditem. Thanks for any feedbacks.

RadPanelBar1.SelectedItem.Value = "2";
RadPanelBar1.DataBind();
RadPanelItem test = (RadPanelItem)RadPanelBar1.SelectedItem;

 

 

RadPanelItem parent = (RadPanelItem) test.Parent;

Hi Frank,

Please find below a sample code snippet that shows the needed approach.

ASPX:

<form id="form1" runat="server">
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
    </telerik:RadScriptManager>
    <telerik:RadPanelBar ID="RadPanelBar1" runat="server" DataFieldID="MenuId" DataFieldParentID="ParentId"
        DataSourceID="SqlDataSource1" DataTextField="Text" DataValueField="Value">
    </telerik:RadPanelBar>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:testConnectionString %>"
        SelectCommand="SELECT * FROM [panel]"></asp:SqlDataSource>
    <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
    </form>

Code-behind:

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

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

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        RadPanelItem item = (RadPanelItem)RadPanelBar1.FindItemByValue("3");
        item.Selected = true;
        item.ExpandParentItems();
    }
}
