Hi,
I've been using the Image control in the definition of a XAML UserControl,
and I realized that when I set IsEnabled to false, then the bitmap
displayed in the Image control doesn't get grayed out as I was expecting.
I've been trying to create a similar control (or one that inherits from
Image) that I could use from XAML and bind its properties.
The idea is that I am binding the Source property of my image instance to a
property of a data type that I have created (the property is actually a
string of the location in the disk of the jpg file). So I need the new
control to be able to be binded to.
I tried using a FormatConvertedBitmap instance as the ImageSource of the
Image.Source property, and giving it a BitmapImage instance, but I couldn't
bind the BitmapImage to the path of the image on the disk.
I also though on creating my own BitmapEffect, which would be a better
solution, but these are very complicated to write since you need to meddle
with some unmanaged code and COM interfaces, so I gave up this idea.
Has someone succeded in doing something similar?
I would like to end up with something like a control called
GrayeableImage...
TIA
Uriel
