Web Custom Control default rendering

[kurt sune]

I have quite an annoying error.

I have created a web custom control.

When I put it on a web page I do not get: "The control's default
rendering, which is simply the name of the control followed by its ID,
appears in the Design view. "

Instead I get only the small little green arrow. I do not get "the name of
the control followed by its ID".

What have I done wrong?

When VS.NET is in design mode with a custom control, it actually creates
an instance live in the designer. That live instance is actually rendered,
so my guess is that your Render method isn't doing anything very interesting,
thus the pseudo-blank space.

According to the helpfiles I should at least get some text, something like
"ControlName.ControlId" behind the green arrow.

If your control fails to render in the designer (such as throwing an exception),
then you'll see the behavior you describe.
