Hi, I just start to learn about api control. When I try to add an api control, I got the error:
"topobase" unable to cast object of type 'xxxxxx' to type 'System.Windows.Forms.Control'.

Could anyone tell me the reason? Thanks in advance.

Hi hu,brett

Did you ever figure out what the problem was?

I would post more details if you haven't, like how you added the api control.

how did you add an API control? I agree with D, you should post more details if you haven't found a solution.
Did you cast your control type?
i.e: _BtnMyNewButton = this.Dialog.Controls.ApiItem("$THEAPIBUTTONNAME") as Topobase.Forms.Button;
