Show own UserControl from Smart Client plugin

Hi, I want to show a popup (own UserControl) when I click on a button that is in a workspace plugin.

When I try this, nothing happens:

  private void bttnSelectCams_Click(object sender, EventArgs e)
        {
            SelectCamsUC uc = new SelectCamsUC(AllCameras, Cameras);
            uc.Show();
        }

A UserControl will never work unless hosted by a form. Can you please describe what you want to do?

Indeed, when hosted by a form it works. Forgot about this.

Thanks for your reply!
