Controlling tab Colors

[bobebs]

How do I programmically change the color of a tab(s) on the tabstrip depending certain conditions.  I tried changing both the foregcolor and backcolor properties but it does not work.  Do I have to change the "theme"?  if so how?

Hello Bob,

You could use the ClassSelector class to select the fill of the TabItem and then modify the BackColor 
properties of that TabItem. The following code demonstrates how to change the backColor of an instance of TabItem.
   
    ClassSelector fillSelector = new ClassSelector("TabFill");
    FillPrimitive tabFill = fillSelector.GetSelectedElements(this.tabItem2)[0] as FillPrimitive;
    tabFill.BackColor = Color.Red;
    tabFill.BackColor2 = Color.Red;
    tabFill.BackColor3 = Color.Red;
    tabFill.BackColor4 = Color.Red;

The next block demonstrates how to reset the values of the BackColor properties.

     ClassSelector fillSelector = new ClassSelector("TabFill");
     FillPrimitive tabFill = fillSelector.GetSelectedElements(this.tabItem2)[0] as FillPrimitive;
      tabFill.ResetValue(FillPrimitive.BackColorProperty);
      tabFill.ResetValue(FillPrimitive.BackColor2Property);
      tabFill.ResetValue(FillPrimitive.BackColor3Property);
      tabFill.ResetValue(FillPrimitive.BackColor4Property);

I hope this helps.

How would I do the same thing for the various states of the tabs?

Hello BillFugina,

I think the only possible approach here is to handle the Mouse events of the control and apply different colors in the different states. However the best approach is to build your own custom theme using our tool for building themes - VisualStyleBuilder. You can find more information about it here:
