如何在WPF ComboBox中正确显示太长的文本 [英] How to display too long text properly in WPF ComboBox

问题描述

我有一个ComboBox，可以显示各种长度的文本.对于不长的文本，没有问题.对于长度超过ComboBox宽度的文本，我要修剪文本并在末尾添加"..."(省略号)以正确显示它们.最重要的是，我不想更改ComboBox的宽度.有人知道该怎么做吗?

解决方案

为您的ComboBox使用自定义ItemTemplate，该自定义ItemTemplate使用TextBlock，并且TextTrimming属性设置为CharacterEllipsis./p>

示例:

<ComboBox ItemsSource="..." SelectedValuePath="...">
  <ComboBox.ItemTemplate>
    <DataTemplate>
      <TextBlock 
        Text="{Binding ...}" 
        TextTrimming="CharacterEllipsis" />
    </DataTemplate>
  </ComboBox.ItemTemplate>
</ComboBox>

I have a ComboBox that shows text of various lengths. For texts that are not long there is not a problem. For the texts longer than the width of ComboBox I would like to trim the text and add "..." (an ellipsis) at the end to show them properly. The bottom line is that I don't want to change the width of the ComboBox. Does anyone know how to do this?

解决方案

Use a custom ItemTemplate for your ComboBox, which makes use of a TextBlock with the TextTrimming property set to CharacterEllipsis.

Example:

<ComboBox ItemsSource="..." SelectedValuePath="...">
  <ComboBox.ItemTemplate>
    <DataTemplate>
      <TextBlock 
        Text="{Binding ...}" 
        TextTrimming="CharacterEllipsis" />
    </DataTemplate>
  </ComboBox.ItemTemplate>
</ComboBox>
