Missing example references?      MSearles   |   Edit   |   Show History
Hi,

Possibly not the best place to put this, but pasting the example into a ResourceDictionary throws up errors

The attachable property 'VisualStateGroups' was not found in type 'VisualStateManager'.

and

The type 'primitives:DatePickerTextBox' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.

Could the relevant xmlns's be included in the sample?

Thanks,
Matt


XMLNS for the Sample      Wolf Schmidt - MSFT   |   Edit   |   Show History
Hi: sorry about missing the xmlns. What happens when we compose the example code is we pull that code out of larger projects. The xmlns is almost always on the root and yet we don't want to show you all the XAML including the root for some of the larger files. We have a way to do this but it's tricky and sometimes we ummm forget.

xmlns:local="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"

xmlns:primitives="clr-namespace:System.Windows.Controls.Primitives;assembly=System.Windows.Controls"

xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows"
About the vsm xmlns. The prefix exists because some of the design tools had a glitch about picking up the readonly attached property VisualStateManager.VisualStateGroups without special casing it into a custom namespace. But I'm not positive that the requirement to use vsm for mapping VisualStateManager still exists with the XAML design tools that are released.
