RadPanelBar Collapse All items is not working

[Amjath]

Hello All,

I want the RadPanelBar to load by collapsing all the items, if the user need to see and they can expand, but collapse all is not happening at all.

In my case my datasource will be like this

Item1

     --Item1.1

     --Item1.2

 

while loading the page I want to see only the Item1 alone

Mark up code:

<telerik:RadPanelBar ID="rdPnlOrgDetail" RenderMode="Lightweight" OnDataBound="rdPnlOrgDetail_DataBound" runat="server" OnPreRender="rdPnlOrgDetail_PreRender" AllowCollapseAllItems="true" ExpandMode="SingleExpandedItem" OnClientLoad="collapseAll">
    
</telerik:RadPanelBar>

 

Dynamically adding the Items 

rdPnlOrgDetail.CollapseAllItems();
           
            var source= getSource();

            rdPnlOrgDetail.Items.Clear();
            RadPanelItem orgItems = new RadPanelItem();
            orgItems.Text = string.Format("{0} : {1}", orgChart.First().OrganisationScope.Scope, orgChart.First().Name.ToString());
            orgItems.Expanded = false;

            for (int i = 1; i < orgChart.Count; i++)
            {
                RadPanelItem orgItem = new RadPanelItem(string.Format("{0} : {1}", orgChart[i].OrganisationScope.Scope, orgChart[i].Name.ToString()));
                orgItem.Expanded = false;
                orgItems.Items.Add(orgItem);
                orgItems.Expanded = false;
            }
            orgItems.Expanded = false;
            rdPnlOrgDetail.Items.Add(orgItems);
            rdPnlOrgDetail.CollapseAllItems();

 

please do the needful.

 

With Thanks

Hello ,

In the attachment, you will find the sample page, that we used to recreate the described scenario. You could use it as a reference.
