I have a button with a backgroun image of color white. My button is sitting on the toolbar which has a bacground color of Blue. When the button is sitting on the toolbar, th
You can use the System.Windows.Media.Color
Transparent
, like this:
<Button Background="Transparent" />
Are you sure you want to use an image? If the image is just a solid color, you're probably better off just setting the button's background to white and adjusting its opacity. Like:
<Button Background="White" Opacity="0.5" />
Where Opacity can be any value between 0 and 1.
EDIT: I'm not sure what you mean by "shades." Are you aware that you can set the background of a Button to a gradient? You'll want to change the colors I'm sure, but it will look something like this:
<Button>
<Button.Background>
<LinearGradientBrush>
<GradientStop Color="Yellow" Offset="0.0" />
<GradientStop Color="Orange" Offset="0.5" />
<GradientStop Color="Red" Offset="1.0" />
</LinearGradientBrush>
<Button.Background>
</Button>
You have to make sure your image has transparency, WPF won't try to figure out what parts in your image should be see-through and what parts should be opaque. Check that your image editor can export images with transparency, most likely to PNG.
