如何传递 IValueConverter 参数? [英] How to Pass IValueConverter Parameter?

问题描述

在XAML中，，这里我想把MainGrid3作为IValueConverter.我该怎么做?

In XAML, <Grid x:Name="MainGrid3">, Here I want to pass MainGrid3 as a parameter of IValueConverter. How can I do this?

推荐答案

您的绑定中有 ConverterParameter，您可以在其中使用另一个绑定与网格的 ElementName.

You have ConverterParameter inside your binding, where you can use another binding with ElementName of your grid.

<Grid Name="MainGrid3"></Grid>
<TextBlock Text="{Binding SomeBinding, Converter={StaticResource SomeConverter}, 
           ConverterParameter={Binding ElementName=MainGrid3}}"></TextBlock>

好吧，显然我错了，您不能在 ConverterParameter 中使用绑定，因为它不是依赖属性.可行的解决方案是像这样使用 x:Reference :

Ok, so apparently I was wrong, you can't use bindings inside ConverterParameter as it is not a dependency property. Working solution would be to use x:Reference like so:

<Grid Name="MainGrid3"></Grid>
<TextBlock Text="{Binding SomeBinding, Converter={StaticResource SomeConverter}, 
           ConverterParameter={x:Reference Name=MainGrid3}}"></TextBlock>
