Have a look at this article: http://www.designerwpf.com/2008/02/04/how-do-i-wrap-text-in-the-combobox/[^] I found this using www.live.com and seached for: wpf combobox texttrimming

Hi Karl, Thank you for the reply. I actually did see this article before posting. I could not get it to work. How do I set the DataTemplate for the combobox?

Here is a code snippet from one of my programs. Cheers, Karl » CodeProject 2008 MVP My Blog | Mole's Home Page | XAML Power Toys Home Page Just a grain of sand on the worlds beaches.

hmm. I must have something wrong. My code is below. When I select the item that is longer than the width of the combobox it does not show the ellipsis characters. Any thing that you can see that I am doing wrong? Electronics, Game Systems, Cameras & Photo Computers and Networking Clothing, Shoes, and Accessories Books, Music, Movies, DVDs, and Video Games All Other Categories

I see what you mean. I have a hack, but want to give you a better solution. I'm in the middle to posting a new version of XAML Power Toys, so I'll get back to this tomorrow night after work. For now, move ahead, we'll get this.

Aaron, I've spent the entire weekend updating XAML Power Toys for Silverlight and just published it. I'll hop on this Monday after work. I'm just plain beat and brain is out of gas. I need my creative gas tank full to give you a solution that is not hacky.

Perhaps you can use a valueconverter (erm.. somewhere)

Aaron, I've spent and hour got it to work but it had an unexpected behavior. So I'm retemplating the ComboBox to support this. I had to download Blend to do this. Should be another hour or so.

Below are two solutions. One when the ComboBox ItemSource is data bound. The second when the ComboBox items are added in-line. You can thank Code Project MVP Josh Smith for this solution. He is the real, "Man" and Mr. WPF. Josh's blog: http://joshsmithonwpf.wordpress.com/ <Setter Property="ContentTemplate"> <Setter.Value> <DataTemplate> <TextBlock Text="{TemplateBinding Content}" TextTrimming="CharacterEllipsis"/> </DataTemplate> </Setter.Value> </Setter> Greetings from the planet known as Earth Thanks to Josh Smith for this tip!

I was just checking up on your blog. Good stuff. I really appreciate your help with this. I had a little bit of both in my attempts, I just could never get the right "combo". Thanks again.
