here i am confused what is your data type. which you are passing to the ItemsSource property of datagrid.
在这里我很困惑你的数据类型是什么。您将其传递给数据网格的 ItemsSource 属性。
if you are usnig DataTable and passing it to datagrid then the below code will work for you.
如果你是 usnig DataTable 并将它传递给 datagrid 那么下面的代码对你有用。
void dataGrid1_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
DataRowView rowview = dataGrid1.SelectedItem as DataRowView;
if (rowview != null)
{
textbox1.Text= rowview.Row.ItemArray[0].ToString();
}
}
and if you are using Typed object for the itemsSource property of DataGrid e.g List of Employees. then here what you can do.
如果您使用 Typed 对象作为 DataGrid 的 itemsSource 属性，例如员工列表。那么在这里你可以做什么。
Employee emp = dataGrid1.SelectedItem as Employee
if(emp !=null)
{
textBox1.Text = emp.Name;
}

private void YourGridName_SelectedCellsChanged(object sender, SelectedCellsChangedEventArgs e)
{
string fc = null;
foreach (var item in e.AddedCells)
{
fc =((System.Data.DataRowView(item.Item)).Row.ItemArray[0].ToString();
}
}

You may try adding a handler for the DataGrid SelectionChanged Event, as follows:
您可以尝试为 DataGrid SelectionChanged 事件添加一个处理程序，如下所示：
private void dataGrid1_SelectionChanged(object sender, RoutedEventArgs e)
{
DataRowView rowview = gv.SelectedItem as DataRowView;
string textNeeded = rowview.Row[0].ToString();
}
