Toolbar/ToolbarItem have been from 3.0 after being depreciated at 2.3.  So you will need to refactor your application to not use these objects in order to upgrade to 3.0 http://resources.arcgis.com/en/help/silverlight-api/concepts/index.html#//0166000000m9000000 ... View more

Joe, Thanks for the additional information. I decided to stick to the current thread only.So, I fired my all queries one after another.That's heavy operation but it worked. Sanjay, Glad it worked for you.  It really is not a heavy operation because the Silverlight client application is not doing any of the work.  Take a look at http://msdn.microsoft.com/en-us/library/system.net.webclient.aspx.  The ExecuteAsynch methods on a Task are basically wrappers for the WebClient::OpenReadAsych method that build the Url/Query String from the parameters provided.  So all that happens on the Silverlight side is the sending of a message to the server.  All the processing is done by the ArcGIS Server process (a SOC process running on the server) and the Silverlight application just waits around for the results to be sent back. -Joe ...

Kim, I appreciate the time you took setting t on my his up.  I kind of jump between trying to run on the server and working desktop.  I think I may try to reinstall python on my desktop and see what that does.  I basically cannot seem to create a SearchCursor in any way, even just in the py window with an existing table. I have a related question.  I think there is something I am just not grasping here.  I do have the script successfully creating the path output table as a geoprocessing service.  I did finally realize that my output variable should be index 3, as you note in your comments (was thinking output started at 0) So I have the table in my scratch workspace and I want to to just send that table back to the caller of the service as a result how does one go about doing that.  I have tried different ways of defining the output parameter and calling both SetParameter or SetParamaterAsText.  Always get that "Object error in setting parameter....'.  I know there is something really fundamental I am just not getting my head around, could you possibly point me in the right direction? Cheers -Joe ... View more

I am suspicious of your query to open the cursor. Is ObjectID a string? If not it needs to be cast to a string. What happens if the result is no records? Add some print statements to print out what is returned. I have never used the row variable in a cursor, always row.attribute, what does row return? Update and Insert cursors work differently and since you haven't added a new row it probably just does nothing. You also need to close the cursor but I suppose that you are relying on the local variables in the function. I would still explicitly 'del cursor' You may have more success by rearranging your whole script. I would avoid opening and reopening a cursor just to get one record. Maybe get all the values in one pass and put into a python dictionary? That would be much faster. Kimo, Thanks for the reply, perhaps my initial post was not clear this line throws the error ( global name 'gp_' in not defined) . cursor = arcpy.SearchCursor(table, where) It throws the error if the where clause is not in there and if I just pass the table in (but yes objectId is a string).  The table is created in the exportCatalog method so perhaps it has something to do with trying to query a table that was just created. I cannot put in statements to see what is returned because it blows up on that call The purpose of the script is to retrieve only the one value (at this point), so it is not running multiple times to retrieve multiple values.  I am quite inexperienced with python and geoprocessing so I am sure I am not doing this in the most efficient manner but right now I am just trying to get what seems a pretty straightforward script to work as a geopocessing task Cheers -Joe ...

Hi Joe, 1. I've decided to give up on preserving the last tool meanwhile so, at the moment, I don't need the QueryComplete event at the end.    I do need to check, whether the Url of the active layer is equal to X or equal to None and if the answer is yes, do not execute the spatialQueryAction.    Is that possible without writing my own spatialQuery? 2. Please send me the sample of a FeatureDataGrid and FeatureDataForm integrated into a DraggableWindow. I hope I don't nagg too much... So many thanks, Miri The RelatedEdt zip is an example of an app that has a DataGrid and DataForm working together and hosted in a DraggableWindow.  There has been something wrong with ESRI's sample server for the last day so I have not finished a couple tiny spots.  This was actually written to edit records in a related table.  The user clicks on a point and if it has related data in the table the DataGrid is loaded.  When a record in the Grid is selected the form is loaded so the record can be edited.  There is an Add button to add a new record in the related table.  I think it should be relatively straight forward to change to just edit the features not related records I also attached a custom DraggableWindow that does a minimize to just the title bar.  It has a lot of stuff in there that is there as part of the application framework I have developed, so it won't work as is but maybe give some ideas of how to go about it.  I also added some gee-wiz animation to the close.  There is also something you may find interesting in that it can flip from LeftToRight to RightToLeft dynammically Hope that helps ...

Apologizes for not posting a more complete code sample initially import arcinfo import arcpy import sys def main():     global mosaicDb     global pathtable     pathtable = '%SCRATCHWORKSPACE%/Scratch.gdb/Paths'     mosaicDb = '//sdm7/arcgis/Mosaics/imagery_datasets.gdb/'     inputmosaic = arcpy.GetParameterAsText(0)     objectid = arcpy.GetParameterAsText(1)     arcpy.AddMessage('Input Mosaic Dataset: ' + mosaicDb + inputmosaic)     arcpy.AddMessage('Search SourceObjectID: ' + objectid)     deletePathDb()     exportCatalog(inputmosaic)     fs = getMosaicRow(objectid, pathtable)     arcpy.SetParameter(0, fs) def deletePathDb():     try:         arcpy.Delete_management(pathtable)         arcpy.AddMessage('table deleted successfully')     except:         #catch because will throw error if table not there         arcpy.AddMessage('Error attempting delete path table')         arcpy.AddMessage(arcpy.GetMessages()) def exportCatalog(name):     try:         fullname = '//sdm7/arcgis/Mosaics/imagery_datasets.gdb/' + name         arcpy.ExportRasterCatalogPaths_management(fullname, "ALL", pathtable)     except Exception as e:         arcpy.AddMessage("Error export catalog")         arcpy.AddMessage(arcpy.GetMessages()) def getMosaicRow(objectId, table):     where = 'SourceOID = ' + objectId #this is line that explodes     cursor = arcpy.SearchCursor(table, where)         fs = None     for row in cursor:         fs = row         return fs     As I mentioned above, if I replace SearchCursor with UpdateCursor or InsertCursor it works without error, which is the thing that has my head spinning the most.  I have certainly not consciously modified any of the core .  I am using 10.0 with Python26 Thanks for you help ...

Anyone have any ideas about this?  I basically cannot use a SearchCursor in any script, the same error occurs (as expected) in the Python window.  Why would this only occur on a SearchCursor when everything else is working without issue. ... View more

Sanjay, While it is certainly possible to run the queries on multiple threads as andrew points out these are asynchronous operations so you will not achieve any performance improvements by doing so.  As soon as one query launches the next will launch immediately and they will all be running on the server in a multi-threaded fashion, which is where the processing occurs.  Just create an individual method for each query with its own QueryTask object and call each method in sequence, it will be a lot simpler and will perform identical to running each on its own thread. Good luck ... View more

Hi Joe, 1. Now it is finally works. I wasn't aware of all these DataContext issues....I'm studing and programming at the same time so I miss things. I haven't tried the symbol yet but I'm sure it will work. Thanks a lot! Personally for me, understanding how DataContext works took a bit, it does open up a lot more in Silverlight once it makes sense 2. So sweet of you to write this code on action completion. The thing is that if there is so much code for it, I don't see the advantage of using it instead of QueryTask. Can you see any advantage? THe advantage and the nice thing about TriggerActions is it is a good way to separate business logic away from the UserControl code behind, really a design decision more than anything else 3. How do you know what is: Toda Raba? Falls in the things we learned before we were 13 category I guess.;).  I spent one summer in your home back during high school and hope to visit again soon because I am working in the region right now 4. Do you have a tip/sample for wrapping DataGrid (or featureDataGrid) in a draggable/floatingWindow with close button? I saw some threads about it in the forum but couldn't find someting that attracted me. What I do is create a control that inherits from the DraggableWindow in the Template project and use that to implement that behavior.  I find it a lot cleaner than trying to put everything in the MainPage.  I actually have a sample of a FeatureDataGrid and FeatureDataForm integrated into a DraggableWindow I can post an example later Good Luck ...
