如果单元格的内容大于其宽度，如何在DataGrid中显示省略号？

Question

如果DataGrid控件中某些单元格的内容大于为该列指定的宽度，是否可以显示...？

类似的东西：

-------------------------------
|   Name   |    Last Name     |
-------------------------------
| LongNa.. |                  |
-------------------------------

Answer 1

TextTrimming正是您要找的。使用DataGridTemplateColumn并使单元格模板使用TextBlock，它提供TextTrimming的支持。样本 -

<DataGrid ItemsSource="{Binding ItemsSourceForYourGrid}">
   <DataGrid.Columns>
      <DataGridTemplateColumn Width="20">
         <DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
              <TextBlock Text="{Binding Name}" TextTrimming="CharacterEllipsis"/>
            </DataTemplate>
         </DataGridTemplateColumn.CellTemplate>
      </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

Answer 2

是的，你可以。

试试这段代码，我认为这是有效的：

public static string StringEllipsis(DataGrid grid, string text, float columnWidth)
{
    // you can customize this variables, for your preferences
    string yourEllipsis = "..."; 
    string yourFontFamily = "Arial";
    float yourFontSize = 9F;
    float yourTolerance = 1F;

    Graphics graphics = grid.CreateGraphics();
    if (graphics.MeasureString(text, new Font(yourFontFamily, yourFontSize)).Width <= (columnWidth + yourTolerance))
        return text;

    while (graphics.MeasureString(text + yourEllipsis, new Font(yourFontFamily, yourFontSize)).Width > (columnWidth + yourTolerance))
        text = text.Substring(0, text.Length - 1);

    return text + yourEllipsis;
}

希望这有帮助！
