如何使用CommandParameter传递UserControl？

Question

我使用了DelegateCommand，我希望通过Command传递UserControl。

#region OpenViewCommand
private DelegateCommand<UserControl> _openViewCommand;
public ICommand OpenViewCommand
{
    get
    {
        if (_openViewCommand == null)
            _openViewCommand = new DelegateCommand<UserControl>(new Action<UserControl>(OpenView));
        return _openViewCommand;
    }
}

public void OpenView(UserControl ViewName)
{
    UserControl ctrl = (UserControl)ViewName;
    JIMS.Controls.Message.Show(ViewName.ToString());
}
#endregion

XAML中的命令

<Button Name="btnStockGroups" Command="{Binding OpenViewCommand}" CommandParameter="JIMS.View.Stock.StockGroups">stock group</Button>

Answer 1

如果你给UserControl一个x：Name（例如“MyView”），你应该可以这样做：

<Button Name="btnStockGroups" 
        Command="{Binding OpenViewCommand}" 
        CommandParameter="{Binding ElementName=MyView}">
