对于wpf组合框中的太长的文本 [英] for too long texts in wpf combobox

问题描述

我有一个组合框显示各种长度的文本。对于不长的文本，没有问题，但是文本长于组合框的宽度
我想剪切文本并添加..以正确显示它们。底线是我不想改变组合框的宽度。

推荐答案

为 ComboBox 定制 ItemTemplate ，它使用 TextBlock 将 TextTrimming 属性设置为 CharacterEllipsis 。

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

示例：

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