推荐答案

让我们假设我们有这样的数据网格：

Let''s assume we have data grid like this:

<DataGrid Name="DataGrid1" SelectionMode="Single"

          SelectionChanged="DataGrid1_SelectionChanged">
</DataGrid>

和代码隐藏中的事件处理程序（xaml.cs文件）：

and event handler in code behind (xaml.cs file):

private void DataGrid1_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    var item = DataGrid1.SelectedItem/* as YourBusinessObject*/;

    if (item != null)
    {
        // Your code here
    }
}

您应该投射所选项目到您的业务对象类型。

如果您使用的是匿名类型 ，您可以结合使用 Selector.SelectedValuePath Property [ ^ ]和 Selector.SelectedValue属性 [ ^ ]。

You should cast selected item to type of your business object.
If you are using anonymous types, you can use combination of the Selector.SelectedValuePath Property[^] and Selector.SelectedValue Property[^].

如果你想在按钮点击中选择行，你可以在按钮点击中写下面的代码

If you want selected row in button click ,you can write the below code in button click

Yourbusinessobject object= this.DataGrid1.SelectedItem as Yourbusinessobject ;

和xaml代码中

and in xaml code put

SelectionMode="Single" and SelectionUnit="FullRow" 

。

in datagrid.
