无法单击或选择控件XAML设计 [英] Cannot click or select Control XAML design

问题描述

我在Windows 7的VS2010 WPF上进行开发。我有一个项目不会引发任何错误或警告，可以正常编译，XAML设计可以正常显示，除非我无法在XAML设计视图中单击或选择任何控件。

是什么原因，或者如何找出问题或可能的异常？

解决方案

我通过将一个空网格放置为主 Grid 的最后一个子元素来重现此行为。在VS2010的设计器中，我无法选择任何 Button s。可能是您的问题吗？

 < Window x：Class = WpfApplication1.MainWindow 
 xmlns = http ：//schemas.microsoft.com/winfx/2006/xaml/presentation 
 xmlns：x = http://schemas.microsoft.com/winfx/2006/xaml 
 Title = MainWindow  Height = 350 Width = 525> 
< Grid> 
< Button Content = Button Height = 52 Horizo​​ntalAlignment = Left Margin = 93,74,0,0 Name = button1 VerticalAlignment = Top Width = 113 /> ; 
< Button Content = Button Height = 38 Horizo​​ntalAlignment = Left Margin = 280,100,0,0 Name = button2 VerticalAlignment = Top Width = 96 /> 
 
< Grid>< / Grid> < ;!-这就是问题!!! -> 
 
< / Grid> 
< / Window> 
  

I develop on VS2010 WPF on Window 7. I have a project that does not throw any error or warning, compile fine, XAML design shows fine except I cannot click or select anyone controls in the XAML design view.

What is the reason, or how can I find out the problem or possible exception?

解决方案

I have reproduced this behavior by putting an empty grid as the last child element of my "main" Grid. In VS2010's designer, I cannot select any of the Buttons. Could this be your issue?

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Button Content="Button" Height="52" HorizontalAlignment="Left" Margin="93,74,0,0" Name="button1" VerticalAlignment="Top" Width="113" />
        <Button Content="Button" Height="38" HorizontalAlignment="Left" Margin="280,100,0,0" Name="button2" VerticalAlignment="Top" Width="96" />

        <Grid></Grid>             <!--   THIS IS THE PROBLEM!!!  -->

    </Grid>     
</Window>
