I have an custom control, which has an Image element with its Source property exposed to user, like this:
<ControlTemplate> <Image x:Name="PART_Image" Source="{Binding ImageUri, RelativeSource={RelativeSource TemplatedParent}}"/> </ControlTemplate> where ImageUri is an property in the control class, like this:
public Uri ImageUri { get; set; } This custom control is in an assembly customcontrol.dll, I can reference and use this control in an .exe with no problem, like this:
<cc:MyControl ImageUri="/Resources/Image.png" /> where Image.png is a resource of the .exe project.
But if I reference and use this control in an dll assembly, there is a problem, I have to use a absolute "pack://..." uri to reference an image in the calling dll, if I use an relative uri like "Resources/Image.png", the resource cant be loaded, it turns out, when this uri is applied on the Image element, it resolves the relative uri from customcontrol.dll, not the calling dll assembly, so I want to do this:
public Uri ImageUri { get { ...... } set { if (!value.IsAbsolute) { // Get the assembly name of parent xaml file or code // and construct a "pack://" uri from the assembly name // and value.OriginalString, but how ?????? } } } How can I get the assembly of the XAML code that uses my custom control?
If the control is used in code maybe I can use GetCallingAssembly in my methods, but XAML stuff is called from PresontationCore.dll, how can I find out the XAML assembly???
