Microsoft.Phone.Controls.Toolkit ListPicker引发XamlParseException [英] Microsoft.Phone.Controls.Toolkit ListPicker throws XamlParseException

问题描述

在被告知无法使用本机ComboBox后，我被告知要查看Silverlight Toolkit ListPicker.所以我确实遇到了问题.

After being advised that the native ComboBox was not the way to go I was told to look at the Silverlight Toolkit ListPicker. So I did and have got a problem.

我打开了一个新项目，并将新的ListPicker拉到MainPage上. ListPicker看起来像:

I opened a new project and pulled a new ListPicker onto the MainPage. The ListPicker looks like:

<toolkit:ListPicker x:Name="Result">
    <toolkit:ListPickerItem Content="Win" />
    <toolkit:ListPickerItem Content="Place" />
    <toolkit:ListPickerItem Content="Lose" />
</toolkit:ListPicker>

尝试运行此代码时，我得到一个XamlParseException，其InnerException为InvalidProgramException.我所做的只是拖动控件，并添加一些ListPickerItem.删除项目仍然会导致错误，完全删除ListPicker控件将使该页面得以正确显示.

When trying to run this I get an XamlParseException with InnerException of InvalidProgramException. All I did was drag the control on, and add some ListPickerItem. Removing the items still results in the error, removing the ListPicker control completely allows the page to be shown with no error.

我确定我已经错过了一些东西，但是我阅读的所有文档似乎都指出该标记是可以的，包括 http://windowsphonegeek.com/articles/listpicker-for-wp7-indepth

I'm sure I've missed something, but any documentation I have read seems to point towards this markup being fine, including http://windowsphonegeek.com/articles/listpicker-for-wp7-in-depth

我可以提供所需的任何其他信息.

I can provide any other info required.

推荐答案

问题是已注册了错误的dll，即7而不是7.1.我必须卸载并重新安装才能使其正确更新，并且可以正常工作.

The problem was that the wrong dlls had been registered, i.e. 7 and not 7.1. I had to uninstall and reinstall to get it to update correctly and it worked.
