I have a fairly complex RadScheduler where a user can drop appointments from a RadGrid and the advanced edit form should open on row drop.
This works so far, the form opens. But it seems the form doesn't get initialised correctly. When submitting the form I get a long error message:
"Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors(). Parameter name: scriptControl"
When double-clicking the appointment in RadScheduler, submitting works just fine with the same advanced form, though.
I call this from Page_PreRender(object sender, EventArgs e)
Where would I call "ShowAdvancedEditForm()" correctly?
