Hi All,

I am creating a GIS .net application by using c#, asp.net, MGOS.

I have created my own page as start up page. In start up page I have the
following aspx elements

<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">

    <title>Untitled Page</title>

</head>

<FRAMESET  rows="12%,72%,16%" frameSpacing="0" runat="server" >   

    <frame id="frameTitle" runat="server"  marginwidth="0"
marginheight="0" scrolling="no" src="header_index1.htm" />

      <FRAMESET  cols="40%,60%">    

            <frame id="frameMyTaskList" runat="server" name="frame2"
src="MYTaskList.aspx" />                                      

            <frame id="viewerFrame" name="viewerFrame" runat="server"
marginwidth="0" marginheight="0" scrolling="no" src="MyViewerPage.aspx"
/>

    </FRAMESET>        

    <frame  id="frame4" runat="server" name="frame4"
src="BottomPage.aspx" />                          

</FRAMESET>

<body>

    <form id="form1" runat="server">

    <div>        

    </div>

    </form>

</body>

Now further MYTaskList.aspx page of frameMyTaskList frame is having the
following elements

<body style="background-color: #99ccff">

    <form id="form1" runat="server">

    <div>

    <p style="font-size: 11pt; font-family: 'Book Antiqua'">

    <asp:HyperLink id="lnk1" Text="Task1" NavigateUrl="~/Task1.aspx"
runat="server">

    </asp:HyperLink>

    <br />    

    </div>

    </form>

</body>

Then in Task1.aspx I have the following elements

<script type="text/javascript">

        function MySelection() {

            var selectionXML = '<%= selectionXML %>';

            //alert(parent.parent.frames[1].name);

            parent.parent.SetSelectionXML(selectionXML);      

        }

    </script>

<asp:DropDownList ID="ddlSelectMapName" runat="server"
AutoPostBack="True" OnSelectedIndexChanged=" ddlSelectMapName
_SelectedIndexChanged"></asp:DropDownList>

  <asp:DropDownList ID="myQuery" runat="server" AutoPostBack="true"
OnSelectedIndexChanged="myQuery _SelectedIndexChanged" >

                    <asp:ListItem Text="Item1" Value="
Item1"></asp:ListItem>

                    <asp:ListItem Text=" Item2" Value="
Item2"></asp:ListItem>                </asp:DropDownList>

                <asp:Button runat="server" Text="Show "
ID="btnShowSelection" OnClientClick="javascript: MySelection();" /></td>

On ddlSelectMapName _SelectedIndexChanged  I have generated the map at
run time which is rendering perfecally.

And I have generated the selctionxml in code behind on
SelectedIndexChanged event and is coming pefectally in MySelection
Function of java script, but the problems comes at
parent.parent.SetSelectionXML, I am unable to get the reference of
parent.parent.SetSelectionXML, and also tried in some other ways around
but not getting success in getting the reference of mapFrame or
parent.parent.SetSelectionXML.

I am generating the maps by using the maestro API on run time. So by
setting the MYTaskList.aspx as Initial Task In TaskPane I was not able
to generate the run time maps because it always overwrite my map. so I
had to make my own custom page and call it from my own frame.

Please assist how do I get the parent.parent.SetSelectionXML in my
scenario.

Thanks & Regards,

Ravi
