Hi there

I have been experimenting with loading and saving dock states to a DB but have an issue.

When I run the code the docks are not added to the page - rather they are but the source code has a 'style display:none' so I presume this is hiding the docks?? Its all I can think off as I cant see any other issues.

Can somebody have a look below and see what I am doing wrong........

This is the ASPX.................

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Test Docks.aspx.vb" Inherits="IFM_Code_Testing.Test_Docks" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

            var currentLoadingPanel = null;
            var currentUpdatedControl = null;
            function RequestStart(sender, args) {
                currentLoadingPanel = $find("LoadingPanel1");
                currentUpdatedControl = "TableLayout";
                currentLoadingPanel.show(currentUpdatedControl);
            }
            function ResponseEnd() {
                //hide the loading panel and clean up the global variables
                if (currentLoadingPanel != null)
                    currentLoadingPanel.hide(currentUpdatedControl);
                currentUpdatedControl = null;
                currentLoadingPanel = null;
            }            
        </script>
  
    </telerik:RadCodeBlock>
</head>
<body>
    <form id="form1" runat="server">

                <table id="TableLayout">

                            <telerik:RadDockZone ID="RDZoneLeft" runat="server" Width="300" MinHeight="300" ></telerik:RadDockZone>
                        </td>
                        <td>
                            <telerik:RadDockZone ID="RDZoneRight" runat="server" Width="300" MinHeight="300"  ></telerik:RadDockZone>

    End Sub
  
End Class

And this is the state data from thr db (copied from an example on this site)...

{"UniqueName":"10bcf490-d081-4536-b542-df1564a8cade","DockZoneID":"RDZoneLeft","Width":"300px","Height":"","ExpandedHeight":"203","Top":"0px","Left":"0px","Resizable":"False","Closed":"False","Collapsed":"False","Pinned":"False","Title":"Dock","Text":"Added at 12/3/2009 3:40:54 PM","Tag":"~/Controls/ExchangeRates.ascx","Index":"0"}|{"UniqueName":"35ca0eed-774e-48f6-91ab-91dad4253153","DockZoneID":"RDZoneRight","Width":"300px","Height":"","ExpandedHeight":"138","Top":"0px","Left":"0px","Resizable":"False","Closed":"False","Collapsed":"False","Pinned":"False","Title":"Dock","Text":"Added at 12/3/2009 3:41:05 PM","Tag":"~/Controls/Horoscopes.ascx","Index":"0"}|

I cant seem to find any issues apart from the style one mentioned previously.

Any help greatly appreciated

And this is the source code generated.....

<table id="TableLayout">
                    <tr>
                        <td>
                            <div id="RDZoneLeft" class="RadDockZone RadDockZone_Hay rdVertical" style="width:300px;min-width:10px;min-height:300px;">
        <!-- 2010.2.713.40 --><div class="RadDock RadDock_Default rdPlaceHolder" id="RDZoneLeft_D" style="display:none;">
            <!-- -->
        </div><input id="RDZoneLeft_ClientState" name="RDZoneLeft_ClientState" type="hidden" />
    </div>
                        </td>
                        <td>
                            <div id="RDZoneRight" class="RadDockZone RadDockZone_Hay rdVertical" style="width:300px;min-width:10px;min-height:300px;">
        <div class="RadDock RadDock_Default rdPlaceHolder" id="RDZoneRight_D" style="display:none;">
            <!-- -->
        </div><input id="RDZoneRight_ClientState" name="RDZoneRight_ClientState" type="hidden" />
    </div>
                        </td>
                    </tr>

Ok I have managed to get this working - used an example and went from there.

I set up a simple page and can now load/save from DB.

But.......

When I try and intergrate the working code into a Master Page the docks do not get loaded..

I have a master page setup in which there are 3 ContentPlaceHolders. Then on a child page, based on the Master, I have added the code I have had working.

But when I load the page no docks????

Is there something else I need to do to get it to work with MasterPages?

The code is basically what I have alreayd showed previously.

Thanks in advance
