WPF - 帮助转换XAML绑定表达式代码隐藏 [英] WPF - help converting XAML binding expression to codebehind

问题描述

谁能告诉我什么是C＃相当于XAML ??

的片断的

 <我：DataGridTextColumn 
能见度={绑定路径= DataColumns [21] .IsVisible源= {StaticResource的视图模型}，转换器= {StaticResource的VC}}
绑定={结合SdDevDuration}
 /> ; 
  

其知名度结合我不能得到正确的。 DataGridTextColumn不是FrameworkElement的所以没有SetBinding方法。

在此先感谢，

太

解决方案

我工作了这一点

。对于任何人谁是有兴趣的，你可以使用 BindingOperation.SetBinding方法。

完整的代码，

  VAR NEWCOL =新DataGridTextColumn（）; 
 newCol.Binding =新的绑定（SdDevDuration）; 
 
变种visiblityBinding =新的绑定（可见性）; 
 visiblityBinding.Source =关口; 
 visiblityBinding.Converter =新VisibilityConverter（）; 
 BindingOperations.SetBinding（NEWCOL，DataGridTextColumn.VisibilityProperty，visiblityBinding）; 
  

Can anyone tell me what is the c# equivalent of the following snippet of XAML ??

<my:DataGridTextColumn 
                Visibility="{Binding Path=DataColumns[21].IsVisible, Source={StaticResource viewmodel}, Converter={StaticResource vc}}"                    
                Binding="{Binding SdDevDuration}"
                />

Its the visibility binding I cannot get right. DataGridTextColumn is not a FrameworkElement so no SetBinding method.

Thanks in advance,

Matt

解决方案

I worked this out. For anyone who's interested you can use the BindingOperation.SetBinding method.

The full code is,

var newCol = new DataGridTextColumn();
newCol.Binding = new Binding("SdDevDuration");

var visiblityBinding = new Binding("IsVisible");
visiblityBinding.Source = col;
visiblityBinding.Converter = new VisibilityConverter();                        
BindingOperations.SetBinding(newCol, DataGridTextColumn.VisibilityProperty, visiblityBinding);
