    the dropdown-div of RadDropDownTree is captured within an RadWindow.
    Is there a way to show the dropdown window over the borders of a RadWindow? (ZIndex)

    Thank you

    Hi Stefan,

    I guess you want to show the RadDropDownTree's drop-down over the RadWindow border which is the default behavior. Please check the sample code I tried.

    <telerik:RadWindow ID="RadWindow1" runat="server" OpenerElementID="RadButton1" Width="400px"
            <div style="padding: 10px 10px 10px 15px;">
                <telerik:RadDropDownTree ID="RadDropDownTree1" runat="server" Width="300px" DefaultMessage="Select a product from the list">
    <telerik:RadButton ID="RadButton1" runat="server" Text="Open RadWindow">

    protected void Page_Load(object sender, EventArgs e)
        if (!IsPostBack)
    private static void BindToIEnumerable(RadDropDownTree dropdowntree)
        List<SiteDataItem> siteData = new List<SiteDataItem>();
        siteData.Add(new SiteDataItem(1, 0, "Products", "Value 0"));
        siteData.Add(new SiteDataItem(2, 1, "RadControls for ASP.NET Ajax", "Value 1"));
        siteData.Add(new SiteDataItem(3, 1, "RadControls for Silverlight", "Value 2"));
        siteData.Add(new SiteDataItem(4, 2, "RadGrid", "Value 3"));
        siteData.Add(new SiteDataItem(5, 2, "RadScheduler", "Value 4"));
        siteData.Add(new SiteDataItem(6, 2, "RadEditor", "Value 5"));
        siteData.Add(new SiteDataItem(7, 2, "RadWindow", "Value 3"));
        siteData.Add(new SiteDataItem(8, 2, "RadButton", "Value 4"));
        siteData.Add(new SiteDataItem(9, 2, "RadComboBox", "Value 5"));
        siteData.Add(new SiteDataItem(7, 3, "RadGrid", "Value 6"));
        siteData.Add(new SiteDataItem(8, 3, "RadMenu", "Value 7"));
        siteData.Add(new SiteDataItem(9, 3, "RadEditor", "Value 8"));
        dropdowntree.DataTextField = "Text";
        dropdowntree.DataValueField = "Value";
        dropdowntree.DataFieldID = "ID";
        dropdowntree.DataFieldParentID = "ParentID";
        dropdowntree.DataSource = siteData;
    internal class SiteDataItem
        private string _text;
        private string _value;
        private int _id;
        private int _parentId;
        public string Text
            get { return _text; }
            set { _text = value; }
        public string Value
            get { return _value; }
            set { _value = value; }
        public int ID
            get { return _id; }
            set { _id = value; }
        public int ParentID
            get { return _parentId; }
            set { _parentId = value; }
        public SiteDataItem(int id, int parentId, string text, string value)
            _id = id;
            _parentId = parentId;
            _text = text;
            _value = value;

    Hm, i´m using separate pages within the RadWindow (NavigateUrl) - .

    Seems there is no chance to get a div outside the iframe working (?)

    Hello Stefan,

    Unfortunately the contents of an iframe cannot be displayed outside of the iframe as explained in more details here.
