I am trying to create a blur effect in WPF, but I want to blur the content located behind the control (such as a Grid), I do not intend to blur the contents of the Grid.
I want to do something like this image.
If you are looking for something like this:
The answer is to use a BitmapEffect
:
<Image Source="http://www.pingminghealth.com/wp-content/uploads/2010/12/cherries.jpg" Stretch="UniformToFill">
<Image.BitmapEffect>
<BlurBitmapEffect Radius="20" />
</Image.BitmapEffect>
</Image>
You can find a tutorial about it on msdn: How to Apply a Blur Effect to a Visual.
