Trying to utilize the RadPanelBar but I need it controlled by a RadDropDownList.  I am unsure of how to do this via the code-behind because there is no "ID" associated with them.  Currently they are set to visible=false but would like to make them visible when a user changes the DropDownList. 

If option 1 then show these RadPanelBar options
If Option 2 then show these RadPanelBar options,
etc...

Hi Kurt Kluth,

Please have a look into the full code that I tried.

ASPX:

<telerik:RadDropDownList ID="RadDropDownList1" runat="server" AutoPostBack="true"

    OnItemSelected="RadDropDownList1_ItemSelected">

    <Items>

        <telerik:DropDownListItem Text="Mail" />

        <telerik:DropDownListItem Text="Contacts" />

    </Items>

</telerik:RadDropDownList>

<br />

<br />

<telerik:RadPanelBar ID="RadPanelBar1" runat="server" Visible="false">

</telerik:RadPanelBar>

C#:

protected void RadDropDownList1_ItemSelected(object sender, Telerik.Web.UI.DropDownListEventArgs e)

{

    RadPanelBar1.Visible = true;

    RadPanelBar1.Items.Clear();

    RadPanelItem MainItem1 = new RadPanelItem();

    RadPanelItem subitem1 = new RadPanelItem();

    RadPanelItem subitem2 = new RadPanelItem();

    RadPanelItem subitem3 = new RadPanelItem();

    if (RadDropDownList1.SelectedText == "Mail")

    {

        MainItem1.Text = "Mail";

        subitem1.Text = "Inbox";

        subitem2.Text = "SentItems";

        subitem3.Text = "Outbox";

 

        MainItem1.Items.Add(subitem1);

        MainItem1.Items.Add(subitem2);

        MainItem1.Items.Add(subitem3);

 

        RadPanelBar1.Items.Add(MainItem1);

    }

    else

    {

        MainItem1.Text = "Contacts";

        subitem1.Text = "MyContacts";

        subitem2.Text = "PhoneList";

        subitem3.Text = "SharedContacts";

 

        MainItem1.Items.Add(subitem1);

        MainItem1.Items.Add(subitem2);

        MainItem1.Items.Add(subitem3);

 

        RadPanelBar1.Items.Add(MainItem1);

    }

}

Thanks,
Princy.

Princy,

I tried following your code example and was able to get it to work as you outlined, however I should have included code with the original post in order to have it make more sense.  I already have everything I want to show setup, it is just a matter of showing them.  So maybe it is just modifying the code-behind slightly to get what I need?  Not sure.  See code below:

By default the 4 main items are shown: Favorites, CU Info, Financial, Ratio
If the dropdown changes to Primary or Excess: I need to add some more items to those already shown

Let me know if this helps...

Thank you for your help.  That worked perfectly.
