在DataGrid中已选择的选择行上执行C＃WPF执行操作

Question

I am trying to execute an action SelectedItem on row selected with DataGrid . I have a lot of code so I just put here the relevant parts. If you need more information please tell me.

When I click the row it's selected and the action is executed. It opens another window and lets the user do something there. I also want to let one chose this row again and Action this Set method again, but it's doing nothing until I chose another row and only after I chose another row it lets me get the first row.

In short, I want to be able to execute an action on selecting row1 and then execute it again on selecting row1 again.

My XAML code:

<DataGrid IsReadOnly="True" Name="DataGridProject" ItemsSource="{Binding ProjectList}"
AutoGenerateColumns="False" FontSize="22"
SelectedItem="{Binding SelectedRowItem,Mode=TwoWay}" DockPanel.Dock="Bottom" MaxHeight="300"
MinHeight="350" Height="350" SelectionMode="Single"/>

My ModelView Code:

public class PreTestInformationProjectAccessVM : INotifyPropertyChanged
{
    public DataRowView SelectedRowItem
    {
        get
        {
            return _SelectedRowItem;
        }
        set
        {
            _SelectedRowItem = value;
             // ...        
        }
    }
}

Select current item can't Trigger selectedItem changed event,you can try mouse events like:

<DataGrid.RowStyle>
     <Style TargetType="DataGridRow">
           <EventSetter Event="MouseDown"  Handler="Click_Do" />
     </Style>
</DataGrid.RowStyle>
