How to handle PopupControlContainer deactivate behaviour in WinForms?

WinForms PopupControlContainer control is a popup type of control and by default, the pop-up will be hidden when the user clicks anywhere outside the pop up besides the control.

For example:

If user would like to restrict this, deactivate behaviour and hide it only based on certain scenario. Consider it is needed to hide PopupControlContainer, when user clicks on close button placed in PopupControlContainer, not in other scenarios.

That can be achieved by handling its event named, BeforeCloseUp.

BeforeCloseUp

This event will be triggered, before popup hides.

Following code examples demonstrates the same.

C#

 
// To ensure whether close button is clicked.        
 
bool CloseButtonClicked = false;
  
void popupControlContainer1_BeforeCloseUp(object sender, CancelEventArgs e)
{
   if (CloseButtonClicked)
   {
       e.Cancel = false;
       CloseButtonClicked = false;
   }
   else
       e.Cancel = true;
}

VB

 
' To ensure whether close button is clicked.
 
Private CloseButtonClicked As Boolean = False
 
Private Sub popupControlContainer1_BeforeCloseUp(ByVal sender As Object, ByVal e As CancelEventArgs)
 
                If CloseButtonClicked Then
 
                                e.Cancel = False
                                CloseButtonClicked = False
 
                Else
                                e.Cancel = True
 
                End If
 
End Sub
