I need to be able to pass a querystring value between user controls in a module. Navigation between the controls is implemented in the normal way using the ModuleActions collection. The value to be passed in the querystring depends on user action (the item selected from a drop down list), therefore the Action url needs to be set in a control event handler, and not during the framework call to the ModuleActions property.

I figured I should be able to do this quite simply like this:

         ModuleActions[0].Url = EditUrl("SupplierId", CurrentSupplierId.ToString());

However, though the EditUrl() function returns the Url I want, the ModuleActions[0].Url property value doesn't change (no exception is thrown). Is this a bug, or do I need to change the Url in a different way?

Any help appreciated, thanks in advance.
