You have ConverterParameterinside your binding, where you can use another binding with ElementNameof your grid.
您有ConverterParameter内部绑定，您可以在其中使用ElementName网格的另一个绑定。
<Grid Name="MainGrid3"></Grid>
<TextBlock Text="{Binding SomeBinding, Converter={StaticResource SomeConverter}, ConverterParameter={Binding ElementName=MainGrid3}}"></TextBlock>
Edit: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:Referencelike so:
编辑：好的，显然我错了，您不能在 ConverterParameter 中使用绑定，因为它不是依赖属性。工作解决方案是这样使用x:Reference：
<Grid Name="MainGrid3"></Grid>
<TextBlock Text="{Binding SomeBinding, Converter={StaticResource SomeConverter}, ConverterParameter={x:Reference Name=MainGrid3}}"></TextBlock>
