Hi @Hans Andersen,

There’s no way to achieve this through the application as of yet. However, you could request this as a customization.

In Designer.cs file, you just have to change the SelectedIndex value to the tab which you want the application to open up when you open the form window. Let’s say you want to open up the 2nd tab in the form window, 

Then,

this.picTab.SelectedIndex = 1;

Note that the indexes start from 0.

Hope this helps!

I was hoping to include the tab in the query string, so I could make a lobby like this: 

I just have to find another solution.

Thanks
