[Closed] dotnet EventHandler problem

I wrote a basic custom slider that work pretty well
My problem is when i try to use it in max
I call “dotNet.addEventHandler” to add a function like “functionName sender arg”
It doesn’t do anything for mouseMove event!
Works fine with mouseClick event, why?!
here’s my control class source if it’s useful for anyone

public class Slider : UserControl
{
	#region menbers
	private MathControls MathCtrl;
	// mouse
	private int dragPoint;
	private bool dragging = false;
	// values
	private float Maximum;
	private float Minimum;
	private float value;
	private float percent;
	private float dragValue;
	//drawing	 
	private float corn;
	private int fontSize;
	private float cursHeight;
	private float cursWidth;
	private Rectangle cursor;
	private PointF[] slidBar;
	private PointF[] controlCorner;
	private SolidBrush[] slidBrush;
	private Color BaseColor;
	#endregion
