This Microsoft article talks about this error. http://support.microsoft.com/Default.aspx?id=320268
It specifically talks about a virtual directory using a shared folder but I think your problem is because assembly containing the web control needs to be configured with FullTrust like the web site in the example.

Thanks, Tom. I overcame my ASP.NET trust issue. This article really helped me out: http://forums.asp.net/p/992339/1292466.aspx
But now when I assign the ZoomtoResults control to my pre-existing QueryAttributes task, I get the error: ESRI.ArcGIS.ADF.Web.UI.WebControls.BuddyControlCollection must have items of type 'ESRI.ArcGIS.ADF.Web.UI.WebControls.BuddyControl'. 'ESRI.ArcGIS.ADF.Web.UI.WebControls.BuddyControl' is of type 'System.Web.UI.HtmlControls.HtmlGenericControl'.
Perhaps I need to create a new task from scratch. It seems that nothing is easy for a novice programmer like me.

Success!!! I got it to work. Apparently there is a bug when editing Tasks in the Web ADF, as described here: http://forums.esri.com/Thread.asp?c=158&f=2276&t=209983&mc=4#msgid632784 I changed the BuddyControl code back to "ESRI:BuddyControl" and now everything works! Thank you Tom and Rex!

<p>Does anyone know of any documentation that can be used to help me create context menus for the task results? </p><p>With the out of the box tasks, you get built in functionality where you can right click on a result and get a menu where you can zoom to/pan to a result, remove a result... </p><p>The OOB Find task didnt work for my customer because they wanted some different functionality, with search criteria being dynamically added/removed to the search panel UI with callbacks... Also customized HTML results, not just the standard table.

With a dataset, you get the context menu to remove the result, but no panning/zooming tools. </p><p>How would I go about adding the rightclick context menus for panning/zooming etc? If I can at least get the menu setup I can figure out the callback js and server functions...</p><p>Appreciate any help I can get on this...</p><p>Thx!</p>

<p>The ZoomToResults control expects the Results property of a custom task to be either a System.Data.Dataset that contains DataTables of type ESRI.ArcGIS.ADF.Web.Display.Graphics.GraphicsLayer</p><p>-or-</p><p>a ESRI.ArcGIS.ADF.Web.UI.WebControls.GraphicsLayerNode. </p><p>Thanks,</p><p>-Rex</p>

<p>Hi Roy, </p><p> The only SDK doc that demonstrates the use of ContextMenus is the Common_AddDynamicData sample where a ContextMenu is configured on a Map:</p><p><a rel="nofollow" target="_new" href="http://edndoc.esri.com/arcobjects/9.2/NET_Server_Doc/developer/samples/Web_Applications/Common_AddDynamicData/f80sedfd-ac48-4c81-ba00-5a17e1b09c4b.htm">http://edndoc.esri.com/arcobjects/9.2/NET_Server_Doc/developer/samples/Web_Applications/Common_AddDynamicData/f80sedfd-ac48-4c81-ba00-5a17e1b09c4b.htm</a></p><p> A full discussion of the ContextMenu control and its usage will be provided in 9.2 sp4 and 9.3. I'll write up a blog post on this topic shortly - so look for it coming soon.</p><p>Thanks,</p><p>-Rex </p>

I am having issues with writing a custom task based on the simple task sample, and getting the results formatted to work with this sample...
The problem is the task code is in a seperate project, which doesnt know anything about the mapping application controls. My mapping app sends the value for the Input Property, and the class performs the query and returns the results property and sends it to the taskresults control... That is the only data that is being shared.
How would I pass the Map's current graphicslayer to my task class, so the task can create the featuregraphicslayer? Do I need the current graphicslayer, or can I just create a new one? Is there any sample code available that would do this?
Thank you!

Searching around I found the answer in one of Bryan Baker's posts:
http://blogs.esri.com/Dev/blogs/arcgisserver/archive/2007/05/03/Follow_2D00_up-to-Extending-the-QueryAttributes-Task_3A00_-Zooming-to-selected-features.aspx
This is the key code:
' Get a reference to the Map - have to search the Page since
' task itself has no direct reference to the Map
' (the task's TaskResults does have the ID of the map)
Dim mapCtrl As Map = Nothing
Dim taskResultsId As String =
Me.TaskResultsContainers(0).Name
Dim taskResults As TaskResults = _
CType(FindControlRecursive( _
Me.Page, taskResultsId), TaskResults)
If Not TaskResults Is Nothing Then
mapCtrl = CType(FindControlRecursive( _
Me.Page, taskResults.Map), Map)
End If
and the function it calls:
' Finds the control in the Page's control tree
Public Function FindControlRecursive(ByVal root As _
Control, ByVal id As String) As Control
If root.ID = id Then
Return root
End If
Dim c As Control
For Each c In root.Controls
Dim t As Control = FindControlRecursive(c, id)
If Not t Is Nothing Then
Return t
End If
Next
Return Nothing
End Function
