C#datagrid显示列两次 [英] C# datagrid shows column twice

问题描述

<DataGrid Name="DG" >
    <DataGrid.Columns>     
         <DataGridTextColumn Header="Header" Binding="{Binding Path=name}" />
         <DataGridTextColumn Header="Header" Binding="{Binding Path=date}" />
     </DataGrid.Columns>
</DataGrid>

//dt= select * from birthdate
DG.ItemsSource = dt.DefaultView;

但在数据网格中却显示了2次

but in data grid it shows 2 time

Name | date                | Name | date
ABC1 | 2007-10-10 10:10:10 | ABC1 | 2007-10-10 10:10:10
ABC2 | 2007-10-10 10:10:10 | ABC2 | 2007-10-10 10:10:10
ABC3 | 2007-10-10 10:10:10 | ABC3 | 2007-10-10 10:10:10
ABC4 | 2007-10-10 10:10:10 | ABC4 | 2007-10-10 10:10:10
ABC5 | 2007-10-10 10:10:10 | ABC5 | 2007-10-10 10:10:10

如何仅将其加载一次，而xaml文件中没有任何更改


在此先感谢

how to load it for only one time without any change in xaml file


Thanks in advance

推荐答案

如果要定义自己的列，则需要将AutoGenerateColumns设置为false，否则它会认为您想要添加额外的列，例如

You need to set AutoGenerateColumns to false if you want to define your own columns, otherwise it thinks you want to add extra columns, like this

<DataGrid Name="DG" AutoGenerateColumns="False" >
    <DataGrid.Columns>
         <DataGridTextColumn Header="Header" Binding="{Binding Path=name}" />
         <DataGridTextColumn Header="Header" Binding="{Binding Path=date}" />
     </DataGrid.Columns>
</DataGrid>
