如何在Silverlight中将子元素的宽度绑定到父元素的宽度 [英] how to bind width of child element to width of parent element in silverlight

问题描述

我有一个宽度为1 *的网格。所以在运行时我想到的实际宽度。

在该网格中我有另一个网格，其宽度我想设置为父网格的运行时宽度。我怎样才能做到这一点在XAML通过结合

解决方案

什么有关设置子<网格和GT;'的的 Horizo​​ntalAlignment以拉伸中，这是默认的，实际上？

你也可以随时附加到父< Grid>'s SizeChanged事件 [ ^ ]并从 SizeChangedEventArgs [ ^ ]或读取父 ActualWidth Property 。



一般绑定方法应如下所示：

 <   grid     width   =  {Binding ElementName = LayoutRoot，Path = ActualWidth}   < span class =code-keyword> /  >  

但在我测试时，它仅适用于VS设计师和不是在运行时间。为什么？ - 不知道：（

是的，我之前尝试过，问题是一样的。当我添加一个快速监视时，它显示实际宽度为0.0;（

I have a grid whose width is "1*". So the actual width desided at runtime I think.
Within that grid i have another grid whose width i want to set to the runtime width of parent grid. How Can i do that in xaml through binding.

解决方案

What about setting the child <Grid>''s HorizontalAlignment to Stretch, which is default, in fact?
Also you can always attach to parent <Grid>''s SizeChanged Event[^] and get value from SizeChangedEventArgs[^] or read parent ActualWidth Property.

General Binding approach should look like this:

<grid width="{Binding ElementName=LayoutRoot, Path=ActualWidth}" />

but as I tested it, it worked only in VS designer and not in run-time. Why? -don''t know :(

Yes I have previously tried that and the problem is same.And when I add a quick watch it shows actual width 0.0 ;(
