DoubleEditBox Set font color - foreground

Hi Neil,

The problem here is that thre are many foreground and background brushes that come into play with the edit boxes.  You don't really want to do theming with the Foreground/Background properties, as they won't hit all the brushes.  Instead, you want to alter all our Brush theme resources defined in the AssetResourceKeys that apply to edit boxes.  That's how we achieve theming.

These would be resources like:

• AssetResourceKeys.EditBackground*
• AssetResourceKeys.EditBorder*
• AssetResourceKeys.ControlForeground*
• AssetResourceKeys.DropDown*

You can modify the resources per the documentation like this in your App.Resources:

<SolidColorBrush x:Key="{x:Static themes:AssetResourceKeys.ControlForegroundNormalBrushKey}" Color="Red" />
