问题描述

我已将itemsource绑定到Datatable for Datagrid。它显示了多余的列

我的代码：

 和 Width = *  
 < DataGrid x：Name = dataGrid IsReadOnly = True AutoGenerateColumns = False> 
< DataGrid.Columns> 
< DataGridTextColumn Binding = {Binding OrderId}标题= OrderId宽度= * /> 
< DataGridTextColumn Binding = {Binding ProductId} Width = * Header = ProductId /> 
< DataGridTextColumn Binding = {Binding UnitPrice} Width = * Header = UnitPrice /> 
< DataGridTextColumn Binding = {绑定数量}宽度= *标题= Quantity /> 
< DataGridTextColumn Binding = {绑定折扣}标头=折扣 
 Width = * /> 
< /DataGrid.Columns> 
< / DataGrid> 
  
 解决方案2： 
您可以进行以下设置：您的要求
 < DataGrid HorizontalAlignment = Left Margin = 50,0,0,0 Width = 500 
 Name = dataGrid IsReadOnly = True VerticalAlignment = Top 
 ItemsSource = {Binding Cus} AutoGenerateColumns = True /> 
 
 
 this.dataGrid.AutoGeneratingColumn + = dataGrid_AutoGeneratingColumn; 
 
 void dataGrid_AutoGeneratingColumn（对象发送者，
 DataGridAutoGeneratingColumnEventArgs e）
 {
 e.Column.Width = new DataGridLength（1，DataGridLengthUnitType.Star）; 
}

 解决方案 
Solution 1 : 
Set AutoGenerateColumns="False" and Width="*" for all Columns 
 <DataGrid x:Name="dataGrid" IsReadOnly="True" AutoGenerateColumns="False">
    <DataGrid.Columns>
       <DataGridTextColumn Binding="{Binding OrderId}" Header="OrderId" Width="*"/>
       <DataGridTextColumn Binding="{Binding ProductId}" Width="*" Header="ProductId"/>
       <DataGridTextColumn Binding="{Binding UnitPrice}" Width="*" Header="UnitPrice"/>
       <DataGridTextColumn Binding="{Binding Quantity}" Width="*" Header="Quantity"/>
       <DataGridTextColumn Binding="{Binding Discount}" Header="Discount"
                           Width="*"/>
    </DataGrid.Columns>
</DataGrid>
Solution 2 :You can set like this to achieve your requirement
<DataGrid HorizontalAlignment="Left" Margin="50,0,0,0" Width="500"
          Name="dataGrid"  IsReadOnly="True"  VerticalAlignment="Top"
          ItemsSource="{Binding Cus}" AutoGenerateColumns="True"/>


 this.dataGrid.AutoGeneratingColumn += dataGrid_AutoGeneratingColumn;

 void dataGrid_AutoGeneratingColumn(object sender,
                                    DataGridAutoGeneratingColumnEventArgs e)
 {
     e.Column.Width = new DataGridLength(1, DataGridLengthUnitType.Star);
 }
