Re: Failed to create designer

AlecWhittington:I am creating a very simple control that has the designer
property set to a designer class. After dropping the control onto a page from
the toolbox, it displays "Error creating control" box and the error is
"Failed to create designer..." then the name of the designer class.
The funny thing is, I can right click it and set my custom properties, the
control renders fine when the page is run. 

What the heck am I missing. I have even tried the MS "simpledesigner"
sample with the same results. Any help would be most appreciated.

Lol, it's being almost 4 years since it was opened. 

That means the control is not finding it's designer. People usually refer to the
Designer in a loose manner, that is, as a String. That causes problems like
this. Verify if the namespace is correct and if the class is public
