Ellipsis at start of string in WPF ListView

Question

I have a WPF ListView (GridView) and the cell template contains a TextBlock. If I add: TextTrimming=\"CharacterEllipsis\" TextWr

Answer 1

I implemented (copied) the above TextBlockTrimmer code and it worked great for loading but the TextBlock.Text would not update afterwards, if bound to a View Model property that changed. What I found that worked was to

1. Define a DependencyProperty called TextBlockText in TextBlockTrimmer, similar to the EllipsisPosition property above, including an OnTextBlockTextChanged() method.
2. In the OnTextBlockTextChanged() method, set _originalText to newValue before calling TrimText().
3. Bind the TextBlockText property to the View Model property (called SomeText in the XAML below)

4. Bind the TextBlock.Text property to the TextBlockTrimmer.TextBlockText property in the XAML:

It also worked if I bound both TextBlockTrimmer.TextBlockText and TextBlock.Text to SomeText (but doing so bugs me).
