I am exploring some of the new Property code and are trying to use a DataBound control (GridView in this case) for the edit mode. But pretty soon I realize that this is pretty hard since I don't know when to call DataBind since the IsPostBack can be either true or false depending on how you access the edit tab on the EditPanel. The solution to this problem could be to simply set a property on the IPropertyControl that indicates if this is the initial display or to call a method when the PropertyDataForm switches to the Edit tab. Or is there such a Property/Method that I have overlooked?
