Question

In Winforms you can say

if ( DesignMode ) {   // Do something that only happens on Design mode } 

is there something like this in WPF?

Answer 1

Indeed there is:

System.ComponentModel.DesignerProperties.GetIsInDesignMode

Example:

using System.ComponentModel; using System.Windows; using System.Windows.Controls;  public class MyUserControl : UserControl {     public MyUserControl()     {         if (DesignerProperties.GetIsInDesignMode(this))         {             // Design-mode specific functionality         }     } }
