Ambiguous match found

[Peter]

I have a problem changing a property of the RadTileView control (e.g. IsEnabled) using the properties panel. I get always an error message. I did the following steps:

1. Create a new WpfApplication
2. I dropped a RadExpander control
3. I dropped a RadTileView control
4. Select the RadExpander, click the IsEnabled property in the property panel
   à there is no problem
5. Select the RadTileView, click the IsEnabled property in the property panel
   à I get the message “Property value is not valid”

Error message in MainWindow:

Ambiguous match found.

Hi Peter,
Thank you for the feedback. We'll look into this issue and we'll try to fix it for some of our next releases. I added this as a bug in our PITS under the name "An exception thrown if you try to change some RadTileView property from the property panel" and it will be ready for tracking tomorrow the latest.
I've updated your telerik account and if you have more questions feel free to ask.

Best wishes,
Zarko
the Telerik team
