在DataGrid WPF中获取选定的行项目

问题描述

我有一个 DataGrid 绑定到数据库表，我需要获取DataGrid中所选行的内容，例如，我想显示在 MessageBox 所选行的内容。

DataGrid示例：

所以如果我选择第二行，我的 MessageBox 必须显示如下： 646 Jim Biology 。

谢谢。

解决方案

可以使用SelectedItem属性获取当前选定的对象，然后您可以将其转换为正确的类型。例如，如果您的DataGrid绑定到一系列Customer对象，您可以执行以下操作：

 客户客户=（客户）myDataGrid。 SelectedItem; 
  

或者您可以将SelectedItem绑定到源类或ViewModel。

 < Grid DataContext =MyViewModel> 
< DataGrid ItemsSource ={Binding Path = Customers}
 SelectedItem ={Binding Path = SelectedCustomer，Mode = TwoWay}/> 
< / Grid> 
  

I have a DataGrid, bound to Database table, I need to get the content of selected row in DataGrid, for example, I want to show in MessageBox content of selected row.

Example of DataGrid:

So if I select the second row, my MessageBox has to show something like: 646 Jim Biology.

Thanks.

解决方案

You can use the SelectedItem property to get the currently selected object, which you can then cast into the correct type. For instance if your DataGrid is bound to a collection of Customer objects you could do this:

Customer customer = (Customer)myDataGrid.SelectedItem;

Alternatively you can bind SelectedItem to your source class or ViewModel.

<Grid DataContext="MyViewModel">
    <DataGrid ItemsSource="{Binding Path=Customers}"
              SelectedItem="{Binding Path=SelectedCustomer, Mode=TwoWay}"/>
</Grid>
