Silverlight DataGridTextColumn绑定可见性

问题描述

在我的之后，我现在正在尝试绑定可见性的DataGridColumns到VM通知属性。 建议我可以轻松地做到这一点。

我已经有一个值转换器和VM通知属性，我知道的作品（我有在我的页面上的另一个元素上测试了这些：

 < CheckBox x：Name =chkAllTeamsVisibility ={Binding Converter = {StaticResource BoolToVisibilityConverter}，Path = AllTeams}/> 
  

此复选框控件的可见性反映为当我在DataTextColumn上设置相同的绑定时，我在XAML的 Visibility = 行上得到一个AG_E_BAD_PARSER错误：

 code>< data：DataGridTextColumn 
 Visibility ={Binding Converter = {StaticResource BoolToVisibilityConverter}，Path = AllTeams}
 /> 
  / pre> 
 
 
任何想法任何人？

解决方案
在DataGridTextColumn上的可见性是复选框中的不同的野兽。基本上，它不是依赖属性，不能是数据绑定的。如果您需要此功能，您可以继承DataGridTextColumn并添加您自己的依赖属性来获取行为。
 
 
 
 
 
矩形从UIElement获取其Visibility属性并且是依赖属性
 
 
 DataGridTextColumn从DataGridColumn获取其可见性，不是依赖属性。
 
 
 
Following my earlier post I am now trying now to bind the visibility of DataGridColumns to a VM notification property. MSDN suggests I should be able to do this with ease.

I already have a value convertor and VM notification property that I know works (I have tested these on another element on my page:
<CheckBox x:Name="chkAllTeams" Visibility="{Binding Converter={StaticResource BoolToVisibilityConverter}, Path=AllTeams}"/>
This checkbox control visibility reacts as I would expect. When I set the same binding on the DataTextColumn I get an AG_E_BAD_PARSER error on the Visibility= line of XAML:
<data:DataGridTextColumn
Visibility="{Binding Converter={StaticResource BoolToVisibilityConverter}, Path=AllTeams}"
/>
Any ideas anyone?Thanks,Mark

Visibility on the DataGridTextColumn is a different beast on the checkbox.  Basically, it isn't a dependency property and can't be data-bound.  If you need this functionality, you can subclass DataGridTextColumn and add your own dependency property to get the behavior.
Rectangle gets its Visibility property from UIElement and is a dependency property
DataGridTextColumn gets its Visibility from DataGridColumn and isn't a dependency property.
