Silverlight 3.0：如何将 DataGridColumn 绑定到 ICommand，其中 DataGrid 绑定到 ItemsSource
我有一个绑定到集合的 SL3 DataGrid。数据网格的一列是 HyperlinkButton 列，我想将该列的单击事件绑定到虚拟机中存在的 ICommand。
伪代码：
DataGrid ItemsSource="{Binding someCollection}" DataGridHyperLinkColumn Commands.Command="{Binding myClickCommand}"
现在，在这种情况下，Commands.Command 尝试在 someCollection 中查找 myClickCommand，而不是从 VM myClickCommand 属性获取它。
我还尝试修复 Commands.Command="{Binding Path=DataContext.myClickCommand, ElementName=nameOfUserControl}" 但也失败了。
出路是什么？...我不想使用 BindingHelper 因为 SL3 已经支持 ElementBinding...
I have a SL3 DataGrid bound to a collection. One column of the datagrid is a HyperlinkButton column and I want to bind the click event of the column to an ICommand present in the VM.
pseudo code:
DataGrid ItemsSource="{Binding someCollection}"
DataGridHyperLinkColumn Commands.Command="{Binding myClickCommand}"
Now in this scenario the Commands.Command is trying to locate the myClickCommand within the someCollection instead of getting it from the VM myClickCommand property.
I have also tried the fix Commands.Command="{Binding Path=DataContext.myClickCommand, ElementName=nameOfUserControl}" but that fails as well.
What is the way out...? I don't want to use BindingHelper since SL3 already supports ElementBinding...
