Hi everyone!

I have a windows form which has a UltraExpandableGroupBox control. When the form loads, the control shows collapsed, as it was set at design time. That's fine.

Now I would like to expand/collapse the control at runtime, depending on certain variables on the form. So I tried to set the Expanded property on the control in this way:

     this.grpDetail.Expanded = true;     // (really simple!)

but without any appreciable result.

Curiously, when I debug my application that property is always true, even if the control shows collapsed. Do you have any suggestion? Something I’m missing...?

Thanks, Valentina
