新Blend Preview 5中的绑定问题。 [英] Issue with binding in new Blend Preview 5.

问题描述

自上个月上一次过期以来，我安装了Silverlight 5的新预览版。我现在遇到绑定问题。例如，如果单击旁边的方框以获取元素，请转到数据绑定，单击元素属性选项卡，即使我选择了匹配类型，我的确定按钮
也会显示为灰色。

I installed the new preview for silverlight 5 today since the last one expired last month. I am now having an issue with binding. For example, If I click the square box beside with for an element, go to databinding, click element property tab, my OK button is grayed out even if I have a matching type selected.

所以我将有一个按钮，尝试将其宽度绑定到另一个按钮的宽度，但OK按钮始终显示为灰色。我可以在源中手动键入绑定。然后，如果我回去并尝试对该元素进行数据绑定，则OK按钮将被取消输出
，我可以将数据绑定到正常的其他内容。

So I will have a button, try to bind its width to another button's width, but the OK button is always grayed out. I can type the binding in manually in the source. Then, if I go back and try to do databinding on that element, the OK button is ungrayed out and I can databind to other things like normal.

推荐答案

绑定"确定"使用Windows 8 Consumer Preview评估副本，Blend 4上的按钮也显示为灰色。

The Binding "OK" Button is also grayed out on Blend 4 with the Windows 8 Consumer Preview Evaluation Copy.

Edit...

如果你进入XAML并在XAML代码中开始绑定......

If you go into the XAML and start the binding in the XAML code...

<TextBlock HorizontalAlignment="Left" TextWrapping="Wrap" Text="{Binding }" VerticalAlignment="Top" Margin="0,19.96,0,0"/>

然后该按钮将启用。 

Then the button will become enabled.
