cascading dropdowns on an aspx page works fine but does not work when the two cascading dropdowns are templated in a DetailView control ??? ... "Could not find control <name of the first dropdown> in ControlParameter <name of the parameter>" Am I missing something???
I found the answer to my problem Move the DataSource declaration inside of the DetailsViewInsertTemplate field which has a DropDown that's referencing that DataSource's Id andit'll be able to find controls within the details view.
