How to: Enable Text Trimming

This example demonstrates the usage and effects of the values available in the TextTrimming enumeration.

Example

The following example defines a TextBlock element with the TextTrimming attribute set.

<TextBlock 
  Name="myTextBlock" 
  Margin="20" Background="LightGoldenrodYellow" 
  TextTrimming="WordEllipsis" TextWrapping="NoWrap"
  FontSize="14"
>
  One<LineBreak/>
  two two<LineBreak/>
  Three Three Three<LineBreak/>
  four four four four<LineBreak/>
  Five Five Five Five Five<LineBreak/>
  six six six six six six<LineBreak/>
  Seven Seven Seven Seven Seven Seven Seven
</TextBlock>

Setting the corresponding TextTrimming property in code is demonstrated below.

            myTextBlock.TextTrimming = TextTrimming.CharacterEllipsis

myTextBlock.TextTrimming = TextTrimming.CharacterEllipsis;

There are currently three options for trimming text: CharacterEllipsis, WordEllipsis, and None.

When TextTrimming is set to CharacterEllipsis, text is trimmed and continued with an ellipsis at the character closest to the trimming edge. This setting tends to trim text to fit more closely to the trimming boundary, but may result in words being partially trimmed. The following figure shows the effect of this setting on a TextBlock similar to the one defined above.

When TextTrimming is set to WordEllipsis, text is trimmed and continued with an ellipsis at the end of the first full word closest to the trimming edge. This setting will not show partially trimmed words, but tends not to trim text as closely to the trimming edge as the CharacterEllipsis setting. The following figure shows the effect of this setting on the TextBlock defined above.

When TextTrimming is set to None, no text trimming is performed. In this case, text is simply cropped to the boundary of the parent text container. The following figure shows the effect of this setting on a TextBlock similar to the one defined above.
