Using namespace in DataTemplate DataType

data-binding, datatemplate, namespaces, wpf, xaml

Solution

The namespace containing your type needs to already be mapped in your `xmlns` attribute, i.e.

xmlns:src="clr-namespace:YouTube_Notifier.Google.YouTube" 

{x:Type src:Video}

See also the namespace mapping reference and the reference for `x:Type`...

Problem

I am trying to show a list of videos from YouTube using a ListBox and the ItemsSource property. What I have right now works (Below), but now I need to format my data. ``` <ListBox Name="lbVideos" ItemsSource="{Binding Source={StaticResource listOfVideos}}"/> ``` For that i'm using a DataTemplate but the problem is that the type is Google.YouTube.Video. ``` <Application x:Class="YouTube_Notifier.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Startup="AppStartup" xmlns:src="clr-namespace:YouTube_Notifier" xmlns:System="clr-namespace:System;assembly=mscorlib"> <Application.Resources> <DataTemplate DataType="{x:Type src:Google:YouTube:Video}"> </DataTemplate> </Application.Resources> </Application> ``` The code above results in me getting the error "Type 'src:Google.YouTube.Video' was not found." What I am asking is how do I use namespaces in a DataTemplate?
