Question

I am trying to customize the controls on my WinForms database application.

So far I have only tried to customize labels and buttons using the following code:

namespace MyNamespace
{
  public class CMSLabel : Label
  {
    private Color cmsLabelBackColor = aSystem.LabelBackColor;

    public CMSLabel()
    {
        this.BackColor = cmsLabelBackColor;            
    } 

    [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]

    public new Color BackColor
    {
        get { return cmsLabelBackColor; }
        set { }
    }
  }

  public class CMSButton : Button
  {
    private Color cmsButtonColor = aSystem.ButtonColor;

    public CMSButton()
    {            
        base.BackColor = cmsButtonColor;
    }

    [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]

    public new Color BackColor
    {
        get { return cmsButtonColor; }
        set { }
    }
  }
}

The Button control works perfectly, but the Label controls exhibit no BackColor at all, yet I’ve used the same code for each control type. Can anyone spot what I have done wrong?

You have to change the “base” color:

public CMSLabel()
{
  base.BackColor = cmsLabelBackColor;            
}
