(Improvement) The Click Event of usercontrol is valid for both the left and right mouse keys. How does one make it as sensitive to the left mouse button as the button control?

The click event of usercontrol is valid for both the left and right mouse keys. How does one make it as sensitive as the left mouse button control? (Improvement)

Declare this delegate outside the class:

Public Delegate void mouseclickevent (Object sender, mouseeventargs E );

Rewrite some methods in the class:

/// <Summary>

/// Indicates whether the mouse has been lifted by pressing the mouse.

/// </Summary>

Private bool _ ismouseleftbuttondownmoveup = false;

Protected override void onmousedown (mouseeventargs E)
