RadPanelItem doesnt Collapse

[Levent]

Hi,

I have a  radpanelitem contol and its binding data without any problem.

I inserted manually another radpanelitem into first radpanelitem but second panel doesnt collapse itselfs.

I tried in many way to Expanded = false but It doesnt work.

Thanks for help...

   List<LandingPage> landingPageList = new DepartmentBLL().GetLandingPage(current.ID);
                    if (landingPageList.Count != 0)
                    {
                        RadPanelItem rip = new RadPanelItem()
                        {
                            Text = "Do you know that?",
                            Value = "-5",
                             Expanded = false
                        };

                        foreach (LandingPage lp in landingPageList)
                        {
                            RadPanelItem ripitem = new RadPanelItem();
                            ripitem.NavigateUrl = lp.PageURL;
                            ripitem.Text = lp.LinkName;
                            ripitem.Value = "-5";
                            rip.Items.Add(ripitem);
                            ripitem.Expanded = false;
                        }
                        rip.Expanded = false;
                        RadPanelBar1.Items.Insert(1, rip);
                        rip.Expanded = false;
                     }

Hi Levent,

I have attached the test page where I used your code but I do not seem get the issue that you encounter. Please take a look at it and let me know if I am missing something in your scenario.

Hi,

I'm having the same problem. I'm using the RadPanelBar inside a Sitefinity 3.x project.
I programmatically add items to the panelbar.

Using the code below, the panelbar always opens fully expanded. What should I change to only open the first item?

private void BindData() {

        KtbDataProvider data = new KtbDataProvider(HttpContext.Current);
        IList<KeywordGroup> keywordgroups = data.GetKeywordGroups();
        RadPanelItem rootItem;
        RadPanelItem childItem;

        if (keywordgroups.Count > 0) {

            int index = 0;
            foreach (KeywordGroup item in keywordgroups) {

                rootItem = new RadPanelItem(item.Description);
                rootItem.Style.Add(HtmlTextWriterStyle.Color, item.Color);


                if (item.Keywords.Count > 0) {

                    foreach (Keyword k in item.Keywords)
                    {
                        childItem = new RadPanelItem(k.Description);
                        rootItem.Items.Add(childItem);
                    }
                }

                if (index == 0) {
                    rootItem.Selected = true;
                    rootItem.Expanded = true;
                } else {
                    rootItem.Selected = false;
                    rootItem.Expanded = false;
                }

                this.pnlKeywords.Items.Add(rootItem);
                index++;
            }
        }
    }

This is the markup:

<telerik:RadPanelBar ID="pnlKeywords" runat="server" Skin="Ktb" EnableEmbeddedBaseStylesheet="False"
    EnableEmbeddedSkins="False" ExpandMode="SingleExpandedItem">
</telerik:RadPanelBar>

Hello Daniel,

Try expanding the PanelBar item as described in the following help article - Working With Items Using Server-Side Code.

The problem is that the panelbar items always are expanded. I can't figure out how to collapse them...
