Have Two Errors using dynamically sized Tile View Control

[Michael]

I've been working with the TIleView control and have no more than bound the control to a data source and have run into not one but two un-handled exceptions being caused by the control.

The first of which is when I switch Item Sources from a populated one to an empty one.  I receive the following error:

Value cannot be infinite or NaN.
Parameter name: System.Windows.CustomDependencyProperty

The second error I receive when I try and maximize an item inside of a Tile Control when there is only one item in the data source.  

UIElement.Arrange(finalRect) cannot be called with Infinite or NaN values in finalRect. 

Both Errors can be stopped by adding MaxHeight property to the TileView control, but that causes the control to be malformed and of course not take up all available space.

I have created a test project that shows both of these behaviors in action, if needed. Since I can't attach the project zip I have included some of the code below.

    {

        {
            InitializeComponent();

            //tileView1.MaxHeight = 400; //This Prevents BOTH Errors, but causes control to be Malformed.

            tileView1.ItemsSource = new List<String> { "Test" }; //This Errors on Maximize.
            //tileView1.ItemsSource = new List<String> { "Test1", "Test2", "Test3", "Test4", "Test5" }; //This Works Fine.
        }

        private void tileView1_TileStateChanged(object sender, RadRoutedEventArgs e)

        private void ResetControl_Click(object sender, RoutedEventArgs e)
        {
            tileView1.ItemsSource = new List<String>(); //This Errors Here, but if you set the Inital Datasource to Empty or null it's fine?
        }
    }
}

I am currently working with the latest version of the trial controls (downloaded less than a week ago) have only been working with the TileView control (the specific control we are interested in) today.  I find it very concerning that it's so easy to cause two un-handled exceptions with so little time.  I'm hoping it is just something i'm missing, but several searches have not yet revealed anything.

Hi Michael,

 Thank you for the bug report. There are some issues with the RadTileView when you try to measure it with infinity(when it's inside a StackPanel or a ScrollViewer) and we advise you to use this only when it's really necessary. We looked into the two scenarios that you provided and I hope that the fixes for them will be available with the SP1 (latter this week or next week the latest).
I've attached your project with some small changes (removed the ScrollViewer - the RadTileView has a build-in one and changed the StackPanel with a Grid) so could you please examine it and see if this behavior is what your're looking for.
I've also updated your telerik account and if you have further questions feel free to ask.  

Greetings,
Zarko

Thank you,

That resolved my issues.
