如何以编程方式创建WPF Grid.RowDefintion.Height绑定

Question

这应该很简单，但我被困住了！如何在代码中创建以下多重绑定并将其应用于给定的行定义：

DbContext

谢谢！

你去了：

//Create binding
var binding = new MultiBinding
{
    Converter = new MyMultiConverter()
};
binding.Bindings.Add(new Binding("x") { ElementName = "obj1" });
binding.Bindings.Add(new Binding("y") { ElementName = "obj2" });

//create RowDefinition
var definition = new RowDefinition();
//set binding on HeightProperty
definition.SetBinding(RowDefinition.HeightProperty, binding);

//'myGrid' is the name of the grid instance
//add RowDefinition to grid
myGrid.RowDefinitions.Add(definition);

为了能够在代码隐藏中处理网格，您需要为网格添加名称：

<Grid Name="myGrid">
    ...
</Grid>
