C# WPF-如何获取新插入的行数据行网格

默认情况下，我的网格为空，我试图获取用户插入到我的网格中的行数据，在提交更改后，我必须知道如何获取，我尝试使用grid.SelectedItem，但它总是返回null

我的XAML代码如下

 <DataGrid x:Name="grdInfo" Height="373" VerticalAlignment="Top" DockPanel.Dock="Top" Margin="0,10,0,0" RowEditEnding="grdInfoSave" AutoGenerateColumns="False">
            <DataGrid.Columns>
                <DataGridTextColumn Header="No" Binding="{Binding No}" Width="50" />
                <DataGridTextColumn Header="Description" Binding="{Binding Description}" Width="*" />
                <DataGridTextColumn Header="Total" Binding="{Binding Total}" Width="120" />
            </DataGrid.Columns>
 </DataGrid>

生成表的代码

 private void genTable()
 {
        DataTable dtInfo = new DataTable(); 

        dtInfo.Columns.Add(new DataColumn("No", Type.GetType("System.Int32")));
        dtInfo.Columns.Add(new DataColumn("Description", Type.GetType("System.String")));
        dtInfo.Columns.Add(new DataColumn("Total", Type.GetType("System.String")));

        grdInfo.ItemsSource = dtInfo.DefaultView;  
 }

我需要的是，当用户为

No

列输入1，苹果为描述，200为总计时，我希望获得整行数据。

您可以使用以下命令将新插入的行访问到datagrid

private void grdInfoSave(object sender, DataGridRowEditEndingEventArgs e )
 {
      if (e.EditAction == DataGridEditAction.Commit)
      {
        //Try to get the user inserted value and process it
        DataRow newrow= e.Row.DataContext as DataRow; // If datarow does not work, replace will required databind class.
        String new_desc = newrow["Description"].ToString();
        DataRowView row = (DataRowView)grdQuoteDetail.SelectedItem;
        int No = Convert.ToInt32(row["No"]);
      }
 }

用户在哪里输入数据？@AfzaalAhmadZeeshan在GUI中，我允许属性CanUserAddRow，这意味着用户可以自己添加行否，我的意思是，它是动态的吗？还有，您没有任何类来填充数据吗？@AfzaalAhmadZeeshan我已经发布了生成table.Row.DataContext的方法始终返回null

private void grdInfoSave(object sender, DataGridRowEditEndingEventArgs e )
 {
      if (e.EditAction == DataGridEditAction.Commit)
      {
        //Try to get the user inserted value and process it
        DataRow newrow= e.Row.DataContext as DataRow; // If datarow does not work, replace will required databind class.
        String new_desc = newrow["Description"].ToString();
        DataRowView row = (DataRowView)grdQuoteDetail.SelectedItem;
        int No = Convert.ToInt32(row["No"]);
      }
 }
