请看下面的代码。当我单击 Revert to org order 按钮时，应将列重新排序为原始数据网格顺序。有没有可能？请帮帮我...... //以下是我的代码

您可以在内存中保留一个小字典，并在单击按钮时使用每列的DisplayIndex 属性来重置原始视图。

编辑：添加一个例子

XAML

<Grid>
   <Grid.RowDefinitions>
      <RowDefinition Height="281*" />
      <RowDefinition Height="30*" />
   </Grid.RowDefinitions>
   <DataGrid Name="datagrid1" ItemsSource="12345567" Loaded="datagrid1_Loaded">
      <DataGrid.Columns>
         <DataGridTextColumn Header="Col1" Binding="{Binding}" />
         <DataGridTextColumn Header="Col2" Binding="{Binding}" />
         <DataGridTextColumn Header="Col3" Binding="{Binding}" />
         <DataGridTextColumn Header="Col4" Binding="{Binding}" />
         <DataGridTextColumn Header="Col5" Binding="{Binding}" />
      </DataGrid.Columns>
   </DataGrid>
   <Button Grid.Row="1" Content="Reorder" Click="Button_Click"/>
</Grid>

在你的代码后面：

private Dictionary<int, string> originalOrder;
private void datagrid1_Loaded(object sender, RoutedEventArgs e)
{
   if (originalOrder == null) originalOrder = new Dictionary<int, string>();
   //I will save the header content as a string, 
   //but you can save anything you want to identify each column
   datagrid1.Columns.ToList().ForEach(c => originalOrder.Add(c.DisplayIndex, c.Header.ToString()));
}

private void Button_Click(object sender, RoutedEventArgs e)
{
   originalOrder.ToList().ForEach(k =>
   {
    datagrid1.Columns.FirstOrDefault(c => c.Header.ToString() == k.Value).DisplayIndex = k.Key;
   });
}
