How to get mouseclick from vs designer

How can I determine if a user has clicked on the control in the designer? I would like to change my usercontrol appearance after clicking buttons in that usercontrol.

How can I react on dropping other controls onto my usercontrol? Is there any tutorial for that?

Thank you very much,

mikrogen

Hi mikrogen,

the best way is to derive your own class from
System.Windows.Forms.Design.ControlDesigner (add a reference to
System.Design.dll)

public class MyControlDesigner : System.Windows.Forms.Design.ControlDesigner
{
public override void OnPaintAdornments(PaintEventArgs e)
{
//Design time painting here
//Draw a rectangle around the control
}
}

and add this class to your custom control using the
System.ComponentModel.DesignerAttribute

[System.ComponentModel.Designer(typeof(MyNameSpace.MyControlDesigner))]
public class MyControl : Control
{
public override void OnPaint(object sender, PaintEventArgs e)
{
//Normal painting here
}
}
