Guys
Hope someone can help me! I'm having real problems getting properties I type against a control I have written at design time
I have written a control by inheriting from the Button control. I am trying to add a feature whereby the control changes to a different color when the mouse floats over it, or when the button has the focus. The color changing works if the 'LightColor' is set at runtime in code. However, if I draw the control on a form at design time, change the 'LightColor' property in the Property viewing window, save the form, then close and reopen the form, the property value (as seen in the window) goes back to the default value for the control. It's driving me mad, since I can't see what I've done wrong, although I suspect that the problem is to do with colors not being serialized?
Here is the code for my control
-------------------------------------------------------------------------------
using System
using System.Collections
using System.ComponentModel
using System.Drawing
using System.Data
using System.Windows.Forms
namespace HCS.Components.Control
public class LightButton : Butto
#region Field
private System.ComponentModel.Container components = null
private Color mBackColor
private Color mLightColor
private bool mIsMouseOver
#endregio
#region Constructo
public LightButton(
// This call is required by the Windows.Forms Form Designer
InitializeComponent()
mBackColor = base.BackColor
mLightColor = base.BackColor
#endregio
#region Clean Up Cod
/// <summary>
/// Clean up any resources being used
/// </summary
protected override void Dispose( bool disposing
if( disposing
if(components != null
components.Dispose()
base.Dispose( disposing )
#endregio
#region Component Designer generated cod
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor
/// </summary
private void InitializeComponent(
components = new System.ComponentModel.Container()
#endregio
#region Propertie
[DesignerSerializationVisibility(DesignerSerializat ionVisibility.Content)
[DefaultValue(typeof(System.Drawing.Color), "System.Drawing.SystemColors.Window")
public new Color BackColo
ge
return mBackColor
se
mBackColor = value
SetColour();
[DesignerSerializationVisibility(DesignerSerializat ionVisibility.Content)
[DefaultValue(typeof(bool), "true")
public new bool Enable
ge
return base.Enabled
se
base.Enabled = value
SetColour()
[DesignerSerializationVisibility(DesignerSerializat ionVisibility.Content)
[DefaultValue(typeof(System.Drawing.Color), "System.Drawing.SystemColors.Window")
public Color LightColo
ge
return mLightColor
se
mLightColor = value
SetColour()
#endregio
#region Protected Override Method
protected override void OnMouseEnter(EventArgs e
base.OnMouseEnter (e)
mIsMouseOver = true
SetColour()
protected override void OnMouseLeave(EventArgs e
base.OnMouseLeave (e)
mIsMouseOver = false
SetColour()
protected override void OnGotFocus(EventArgs e
base.OnGotFocus (e)
SetColour()
protected override void OnLostFocus(EventArgs e
base.OnLostFocus (e)
SetColour()
#endregio
#region Private Method
private void SetColour(
if(mIsMouseOver || base.Focused
base.BackColor = mLightColor
els
base.BackColor = mBackColor
#endregio

Thanks in advance!
