How to expand parent panel item ?

[David Blok]

I've got a problem with selected the active node.

It works on the root nodes but not on child nodes, if a child node is selected the root node is not expanded.

 Protected Sub panelmenu1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadPanelBarEventArgs) Handles panelmenu1.ItemDataBound

        Dim dataRow As DataRowView = DirectCast(e.Item.DataItem, DataRowView)

       If functions.FucGetPageID = dataRow("ID").ToString() Then

            e.Item.Selected = True
            e.Item.Expanded = True

        End If

    End Sub

Also viewstate is disabled if it matters.

Frontside code:

<telerik:RadPanelBar runat="server" EnableViewState="false" CausesValidation="False" EnableEmbeddedSkins="False" ID="panelmenu1" Width="100%" OnPreRender="panelmenu1_PreRender" OnItemClick="RadPanelBar1_ItemClick" />

Anyone has an idea how to select the parent node and expand it ?

Hello David,

The following code will help you in expanding the parent RadPanelItem of a particular item.

Code behind:

         e.Item.Selected = true
        (e.Item.Parent as RadPanelItem).Expanded = true

Yes but im looking how to write it down

(e.Item.Parent as RadPanelItem).Expanded = true

That doesn't work.

this works

Dim parentnode As RadPanelItem = e.Item.Parent
parentnode.Expanded = True
