    I have a problem,
    i have an asp.net panel with scrolling. That panel control is built in layers, so the RadDockLayout is one of its layers. The RadDocks control which are added dynamicly to this layer must be relative to a specific point (Top and Left properties). If I remove the scrolling property of the panel then it is works fine, BUT, if I keep the scrolling property and scroll up, down, right or left then the raddock will stay in its postion and will refer to another point in the map (Please view the attached images).

    aspx page:




    td style="width:76%;" >




    <asp:Panel ID="Panel2" Width="710px" style="margin-top:-18px;" BorderWidth="0" Height="390px" runat="server" >




    <asp:Panel ID="bg" Height="410px" ScrollBars="Auto" runat="server" >




    <asp:Image ID="CMapImage" runat="server" />




    <asp:Label ID="Label1" runat="server" Visible="false" Text="Label"></asp:Label><br />




    <asp:Label ID="Label2" runat="server" Visible="false" Text="Label"></asp:Label>








    <asp:Panel ID="LayerPanel1" runat="server">




    <telerik:RadDockLayout ID="RadDockLayout1" runat="server">













    <asp:Panel ID="content" runat="server">




    <table border="0" cellpadding="0" cellspacing="0" width="100%">








    <td align="left" valign="middle">




    <asp:Panel ID="CityNameOnTheMapPanel" style="margin-left:10px" runat="server">




    <asp:Label ID="CityNameLabel" Font-Size="14pt" runat="server" ></asp:Label>&nbsp;




    <asp:Label ID="OnTheMapLabel" runat="server" Font-Size="14pt" Font-Bold="true" Text="ON THE MAP"></asp:Label>












    <td align="right">




    <asp:Label ID="excuteWindowOpenInFullScreen" runat="server" Visible="false"></asp:Label>




    <asp:ImageButton ID="ImageButton1"




    ImageUrl="~/Common/Img/Buttons/FullScreen.jpg" runat="server"




    OnClientClick="UseRadWindow();return false;" />




    <asp:ImageButton ID="ImageButton2" Visible="false" ImageUrl="~/Common/Img/Buttons/Print.jpg"




    runat="server" />



























    c# code:




    RadDock CreateRadDock(string dockNum, string bsnsName, string website, int top, int left, string colr)





    int docksCount = CurrentDockStates.Count;




    RadDock dock = new RadDock();


    dock.ID =


    string.Format("RadDock{0}", dockNum);


    dock.Title =


    string.Format("Dock {0}", dockNum);


    dock.Width =




    dock.EnableEmbeddedSkins =




    dock.Left =




    dock.Top =





    dock.OnClientInitialize =




    dock.DockMode =




    dock.DockHandle =




    dock.Text =


    "<table border='0' cellpadding='0' cellspacing='0' width='100%'><tr><td style='background-color:#" + colr + "; border-bottom-style:solid; border-left-style:solid; border-right-style:solid; border-top-style:solid; border-bottom-width:thin; border-top-width:thin; border-right-width:thin; border-left-width:thin;'><div style='margin:2px;'" + string.Format("<a href='{0}'>{1}</a> ", website, bsnsName) + "</div></td><td>&nbsp;</td></tr><tr><td>&nbsp;</td><td><img alt='' src='Common/Img/Lines/000000.gif' /></td></tr></table>";


    dock.UniqueName =






    return dock;






    void CommonCheckBox_CheckedChanged(object sender, EventArgs e)





    string _iDs = string.Empty;





    DataLstObjctGetData _dataLstObjctGetData = new DataLstObjctGetData();




    DataSet _myDataSet = new DataSet();


    _myDataSet = _dataLstObjctGetData.GetHotSpots(GetCtgryLst(), City, SmallMapPosition);



    DataTable _myDataTable = new DataTable();


    _myDataTable = _myDataSet.Tables[0];



    "HotSpotsDataTable"] = _myDataTable;


    GridView1.DataSource = _myDataTable;





    foreach (DataRow _row in _myDataTable.Rows)





    RadDock dock = CreateRadDock(_row["HSHotSpotID"].ToString(), _row["BBsnsName"].ToString(), _row["BBsnsWebsite"].ToString(), Convert.ToInt32(_row["HSYCord"]), Convert.ToInt32(_row["HSXCord"]), _row["CCtgryColr"].ToString());





    if (_iDs.ToString().Equals(string.Empty))



    _iDs += _row[










    _iDs +=


    "," + _row["HSHotSpotID"].ToString();




    Label1.Text = _iDs.ToString();


    Please, I need your help to make my raddock refers to the same point even if I scroll.
    It is apprecited to send me the modified code.

    Hello Bader,

    Have you considered the RadToolTip control for this specific scenario? It can be configured to be shown relatively to a given point. The following online demo shows how to show ToolTip for different areas of an image: http://demos.telerik.com/aspnet-ajax/tooltip/examples/imagemaptooltipmanager/defaultcs.aspx.

    Now, regarding your issue with the RadDock control. When the RadDock is with DockMode="Floating", i.e. it is not docked to a zone, the dock has position: absolute and is child to the <form/> element. This means that it does not matter whether the dock is over an element, it will always retain its position relative to the <form/>. That's why when you scroll the <div/> (the panel) the dock will not be scrolled together with the other content, because it is not a child to the <div/>. Essentially this is the solution to your issue. Make the dock, child to the panel (<div/>) and set position: relative to the panel.

    For your convenience I created a sample application that makes the dock child to a given element, when the page is loaded for the first time, and on every movement of the dock. Here is the code:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <head runat="server">

            function OnClientInitialize(dock, args)
                var divMap = $get("divMap");
        <form id="form1" runat="server">
        <asp:ScriptManager ID="RadScriptManager1" runat="server">
        <script type="text/javascript">
            //Put your JavaScript code here.
        <div id="divMap" style="width: 700px; height: 400px; overflow: auto; position: relative;">

    Thank you for last reply, it was very useful.
    I have a question, is there any control in your library which doing the same functionality (displaying panel controls in layers)?

    Hi Bader,

    I think RadWindow or RadToolTip might be suitable for  your scenario. The following demo of the RadWindow control shows how to use it as content container: http://demos.telerik.com/aspnet-ajax/window/examples/internalcontent/defaultcs.aspx.
