I imagine a world where there are 20 more Robbies…all producing quality additions to Silverlight such as this.

You complete me Robbie..complete…me..

Thanks for that! It is possible that Silverlight 4 will have this particular problem fixed. It has been marked as resolved(fixed) on connect (https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=372910). However, that’s no guarantee something’s fixed. Connect issues get opened and closed all the time with no explanation and no indication if they’re going to be fixed, so you never really know…

Nice moves, my man. The lack of TextTrimming in SL is one of my biggest peeves. Looking forward to trying it out.

@Scott. Ultimately, completing you was the goal. Sweet! I guess I’m done…

@Stefan. That’s fantastic. I would love for this control to not matter.

@Darren. Maybe we’re even now because you’re port of the Penner equations to WPF has been a staple for me!

Interestingly, a few of my co-workers were experimenting with something similar over the past week or two and did something similar, but it would fail if it had to trim a block of text that was too large. Have you considered using a binary algorithm to figure out the length of the text as opposed to removing one character at a time?

@Paul. Yeah, that sounds like a great approach. For me that means dusting off my old CS books. If anyone wants to take a stab at a binary search approach to this, then by all means do so!

For some reason, Silverlight 2 has a limit on the number of layout passes per page. I think the limit is 250 (see Brad’s blog: http://team.interknowlogy.com/blogs/bradcunningham/archive/2009/07/03/texttrimming-in-silverlight-2.aspx ). That’s why a binary search is needed.

Kiener’s solution gets around the problem by using a second TextBlock that is never displayed and therefore no layout passes are used. You might be able to do something similar.

Thanks for the post!

Any chance you’d contribute it to the SilverlightContrib project?

[...] In Silverlight, you always have to deal with various browser size and display something exactly the same across browser. The problem is especially important for text display. Somehow, if you only have a limted size for text display and the drawback is that some texts are cropped. Therefore, we might want to have a solution to display “…” when some texts need to be trim. Here comes to a solution. Original Post [...]

@Shawn. of course! Please feel free to include this. I’ll send you email as well to make sure you see this.

Thank you so much! This saved me a looot of time!

Hi,
Can I pl have the code for your home page 3D space effect images in Silverlight 3? Thanks a lot. Rajiv

Hey, thanks!

I tweaked the ReduceText Method a bit, because i got an exception when the Text.Length is zero:

///
/// Reduces the text.
///
/// The text.
/// The reduced length text
protected virtual string ReduceText(string text)
{
if (text.Length > 0)
{
return text.Substring(0, text.Length – 1);
}
else
{
return String.Empty;
}
}

[...] Before Silverlight 4 if you wanted to dynamically add ellipses (the commonly used … to show that the sentence continues), you have to invent your own implementation which usually involves creating your own control that wraps a text based control and then manipulate the text inside based on the size.  Similar to what Robby Ingebretsen had to do here.

[...] TextTrimming TextBlock for Silverlight This should work in WPF too. (tags: ui wpf silverlight tips controls) [...]

I am relatively new to Silverlight, but I really need to use this control. The question that I had was, it is possible for me to embed ‘More’, in which case the entire text will be displayed, and ‘Less’ will display the TextTrimmimg TextBlock. With html, this is easy, but I was wondering how to do in Silverlight.

Thanks man, works good other than the argument out of range exception as mentioned above.

[...] to get started, I came across an excellent TextTrimming TextBlock on Robby Ingebretsen’s site: http://blog.nerdplusart.com/archives/texttrimming-textblock-for-silverlight which I used as a basis, and so am releasing my control under the same MIT license that he used. I [...]

Hi Robbie,

Great post, and a very useful control. I used it as a basis for a similar control to auto scale the font size of the textblock up or down to fill the available space, hope that’s okay: http://edventuro.us/2010/03/an-auto-scaling-textblock-for-silverlight/

Nice job, well done!
