[mapguide-users] Problems with selection

Thu Jan 15 13:56:08 EST 2009

I was using RegisterClientScriptBlock in code-behind to set the selectionxml
to the mapframe. This was not working so I changed my logic to do
clientcallback so now I am setting the selectionxml in the aspx page itself.
this seems to work. 

Not sure why the difference. sorry did not get a chance to test the below
scenerio.
Thanks for the response.
