SideDrawerUserCommand namespace?

[Michel]

I want to bind a command to the closed event of the sidedrawer. I added a command property "SettingsClosedCommand" to the viewmodel.
I added this namespace to the xaml:

xmlns:drawer="clr-namespace:Telerik.XamarinForms.Primitives.SideDrawer;assembly=Telerik.XamarinForms.Primitives"

And I added the 3 middle lines of code to the sidedrawer:

<telerikPrimitives:RadSideDrawer DrawerLength="180" DrawerLocation="Top" DrawerTransitionType="SlideInOnTop"  IsOpen="{Binding AreSettingsOpen, Mode=TwoWay}" >

  <telerikPrimitives:RadSideDrawer.Commands>

    <drawer:SideDrawerUserCommand Command="{Binding SettingsClosedCommand}" Id="Closed"/>

  </telerikPrimitives:RadSideDrawer.Commands>  

<telerikPrimitives:RadSideDrawer.MainContent>

etc..

When I try to compile I get this error:

SeverityCodeDescriptionProjectFileLineSuppression State ErrorObject reference not set to an instance of an object.

I found the information here. What am I missing here? Is the namespace correct because it is not mentioned in the article?

Hello Michel,

I cannot be sure what is going wrong with your solution. I tried to recreate it on our side and the code works as expected. I am sending you the page that I used to setup the scenario. The commands are triggered using both approaches. 

Please take a look at the attached file and let us know if you need any further assistance.
