How do I set the Font color of a label to the same as the caption color of a GroupBox?


Question

I want to have some labels on a form with the same font color as the caption on my group boxes, and furthermore I want these colors to change if the user has applied a different Theme on their system.

Can I do this without changing the GroupBox caption from its default?

UPDATE:

I have tried setting the Label ForeColor to ActiveCaption, this looks okay for the Default (Blue) scheme, but when I change the scheme to Olive Green, the label and group box captions are not the same.

Also, the GroupBox normal behaviour is that setting the FlatStyle to Standard sets the caption colour to ForeColor, however to create a new GroupBox and set its ForeColor to ControlText, you must first set it to something other than ControlText and then set it back again. (If you don't follow what I mean, then try it and see.)

Hmm, same question? I'll repeat my post:

using System.Windows.Forms.VisualStyles;
...

    public Form1()
    {
      InitializeComponent();
      if (Application.RenderWithVisualStyles)
      {
        VisualStyleRenderer rndr = new VisualStyleRenderer(VisualStyleElement.Button.GroupBox.Normal);
        Color c = rndr.GetColor(ColorProperty.TextColor);
        label1.ForeColor = c;
      }
    }

From the looks of it a GroupBox draws it's Caption with SystemColors.ActiveCaption, but you'll have to check that with other Themes.

Strangely this is not reflected in the ForeColor property, but if you set that property it takes over.

So the answer is:

private void Form1_Load(object sender, EventArgs e)
{            
  label1.ForeColor = SystemColors.ActiveCaption;
}
