我正在尝试在MVVM架构中实现XamDataGrid列visibilty,它似乎不起作用.

我正在做以下事情:

为未绑定字段添加Visiblility属性 -

<igDP:UnboundField Name="gridCustomerId" 
                   Label="ID" 
                   Binding="{Binding customerid, 
                                     Mode=TwoWay, 
                                     UpdateSourceTrigger=PropertyChanged}" 
                   Visibility="{Binding ShowCustomerIDColumn, 
                                        Mode=TwoWay, 
                                        UpdateSourceTrigger=PropertyChanged}">

在我的视图模型中,添加了一个可见性类型的元素:

//ToShow CustomerID Column
private Visibility showCustomerIDColumn; 
public Visibility ShowCustomerIDColumn 
{
    get
    {
        return showCustomerIDColumn; 
    }

    set
    {
        showCustomerIDColumn=value; 
        InvokePropertyChanged("ShowCustomerIDColumn"); 
    }    
}

然后在命令处理程序中使用以下代码:

if(ShowCustomerIDColumn == Visibility.Hidden) 
    ShowCustomerIDColumn = Visibility.Visible; 
else
    ShowCustomerIDColumn = Visibility.Hidden; 

InvokePropertyChanged("ShowCustomerIDColumn");

有人有解决方案吗？

干杯,安舒曼
