Customising ImageEx #24

Closed darshanrampatel closed 6 years ago

darshanrampatel commented 8 years ago

Hi,

I want to customise the ImageEx control - I have copied the 6 files within the ImageEx directory into my Project and amended the namespace to MyProject.Controls.

However, when I try and use my control, I get the following exception:

System.NullReferenceException: Object reference not set to an instance of an object.
   at MyProject.Controls.ImageEx.MeasureOverride(Size availableSize)

Looking into this, it seems as though _progress is still null at this time, so the line _progress.Width = _progress.Height = Math.Min(1024, Math.Min(availableSize.Width, availableSize.Height)) / 8.0; fails

How can I resolve this?

It seems there is something wrong when you copied the files into your solution. I should review that all the files needed are included in your project with the same file properties in visual studio.

Most likely you didn't merged the default ImageEx XAML theme into Themes/Generic.xaml in your project.

Closing this as no longer relevant (using the Windows Community Toolkit now).
