Detecting Design-time in C#( Native DesignMode property not telling the full truth )
The DesignMode property for a UserControl object will show that it is in DesignMode only if the immediate parent is viewed in the IDE; if it is a grand child of the object that is being viewed in the IDE, then the DesignMode property will not be true.
The workaround:
///
/// Indicates if the current view is being utilized in the VS.NET IDE or not.
///
public new bool DesignMode
{
get
{
return (System.Diagnostics.Process.GetCurrentProcess().ProcessName == "devenv");
}
}

Doesn’t work in Mono, #Develop, etc.
Doesn’t work if you don’t have premissions to query the process parameters.
If the grandchild thing is bothering you, do this:
public override bool DesignMode
{
get {
Control parent = Parent;
while(parent!=null)
{
if(parent.DesignMode) return true;
parent = parent.Parent;
}
return base.DesignMode;

yes Design time need parent
so use ISupportInitialize
code now - think later
public class foobar : UserControl, ISupportInitialize{
#region ISupportInitialize Members
private bool ISupportInitialize_bInit=false;
public void BeginInit() {
ISupportInitialize_bInit=true;
}
public void EndInit() {
ISupportInitialize_bInit=false;
if (this.DesignMode){
foo();
} else {
bar();
}
}
#endregion
}
