[Solved] RadMosaicHubTile updated visibility to collapsed causes null Reference exception

[mark]

I have a RadMosaicHubTile in my app and I bind its PicturesSource to a dynamically generated collection of string urls. When the collection it is bound to is null, I set the tile visibility to collapsed this produces the below error:

   at Telerik.Windows.Controls.RadMosaicHubTile.ProcessIndividualTile()
   at Telerik.Windows.Controls.RadMosaicHubTile.FlipIndividually()
   at Telerik.Windows.Controls.RadMosaicHubTile.Update()
   at Telerik.Windows.Controls.HubTileBase.OnUpdateTimerTick(Object sender, EventArgs e)
   at MS.Internal.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args)
   at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)

Hi Mark,

Thank you for using our RadControls for Windows 8.

I tried to reproduce this issue locally but everything is working as expected on my side. Can you please elaborate a bit more on your specific scenario or send us a sample project or code snippet which reproduces it. Thank you in advance.

I am looking forward to your reply.

 

All the best,

Hello Timur,

Thank you for contacting us.

A Pivot control is available in Windows Phone, not Windows 8. Are you building your application for Windows 8 or Windows Phone? Additionally, some code snippets and/or sample project would be highly appreciated.

I am looking forward to your reply.
