One example of when you might use DesignMode is for design time specific behavior, for instance is when creating a custom control and you want to set its display text equal to the name of the control:

if (DesignMode && string.IsNullOrEmpty(Text))
  Text = Name;

This is a property that let's you know if you are running in Visual Studio Designer. It is helpful when you are writing a custom control and you want it to behave differently during design time.

The DesignMode property will be set to True when you are editing your asp.net page in Visual Studio. For example if you create a chart control you could show a chart based on dummy data during design-time and at run-time generate a chart based on the provided data.
