Panelbar not collapse/expand if I add it at runtime

[Kaushal]

Hi,

Here I am adding panelbar and panelbaritems at runtime. Also I am applying skin to panelbar while I am creating it. As panelbar and all things creates successfully but when I am clicking on panelbar its not collapsing or expanding. Here is my code:

private RadPanelBar PreparePanelBar()

   {

       RadPanelBar objRadPanelBar = new RadPanelBar();

       objRadPanelBar.ID = Guid.NewGuid().ToString();

       objRadPanelBar.Skin = "PanelbarDup"; //This point to my app_themes and from there it ref. to custom skin library

       objRadPanelBar.EnableEmbeddedSkins = false;

       objRadPanelBar.Width = Unit.Percentage(100);

       objRadPanelBar.ExpandMode = PanelBarExpandMode.MultipleExpandedItems;

       return objRadPanelBar;

   }

 

   private RadPanelItem PrepareRadPanelItem(string _rpbCaption,bool isExpanded)

   {

       //Prepare RadPanelItem under passed RadPanelBar

       RadPanelItem objRadPanelItem = new RadPanelItem();

       objRadPanelItem.Text = _rpbCaption;

       objRadPanelItem.Expanded = isExpanded;

       return objRadPanelItem;

   }

 

   protected void btnOk_Click(object sender, EventArgs e)

   {

       //Prepare Tab

       RadPanelBar objPanelbar = PreparePanelBar();

 

       //Prepare Sections

       RadPanelItem objPanelItem = PrepareRadPanelItem("Basic Information", true);

 

       //Prepare Dynamic HTML Table under Section

       objPanelbar.Items.Add(objPanelItem);

 

       // Add the table to the placeholder control

       ContentPlaceHolder.Controls.Add(objPanelbar);

   }

Hi Kaushal,

If you need to have the expand/collapse functionality you should create a root item and then add a child item to it. Alternatively, you can use content template. More on templates you can learn here.
