hello dear telerik team

ive been working with your library for a couple of days the main reason my attention was drawn twards this product was its beautifull tileview but yesterday when i was testing it i ran into an error i couldnt find out the reason of.

well the situation is i have a tile view with a certain number of tiles explicitly named and defined in xaml.all tiles have rad fluid control in them for different states. and i have a number of buttons outside this tile view (two button for each tile). one of these buttons hides the tile if it is shown and the other either shows and mazimizes the tile if its hidden or maximizes it if it is shown but minimized .
well everything is nearly so simple but after i play around with a little showing-hiding-maximising tiles suddenly it jumps out with this error:

Message: Index was outside the bounds of the array.

Hi Sayyed,

I attached the sample project I created based on the code snippets you sent. Unfortunately I wasn't able to reproduce the issue with this solution and as I might be missing something, I wanted to ask you to please test it on your side as well. If you can reproduce the exception in the attached project, we'll appreciate it if you can send us the list of steps that lead to it. Also, if the project should be modified in any way to reproduce the issue, please let us know.

in the project when this annimation is going to take effect i get this error:

exception: [System.Windows.Media.Animation.AnimationException] {"Cannot animate the 'Opacity' property on a 'System.Windows.Shapes.Path' using a 'System.Windows.Media.Animation.ObjectAnimationUsingKeyFrames'. For details see the inner exception."} System.Windows.Media.Animation.AnimationException

inner exception: InnerException {"The animation(s) applied to the 'Opacity' property calculate a current value of '1', which is not a valid value for the property."} System.Exception {System.InvalidOperationException}

thank you in advance for your help and sorry that this is going somehow off topic buty i got the error right after replacing the dlls :)

Hi Sayyed,
The problem is that in WPF when you use ObjectAnimationUsingKeyFrames you have to specify the type of the value (the staticResources specify the type and that's why there's no exception there) like this:

<ObjectAnimationUsingKeyFrames Storyboard.TargetName="OuterBorder" Storyboard.TargetProperty="Opacity">

<DiscreteObjectKeyFrame KeyTime="0:0:0">

<DiscreteObjectKeyFrame.Value>

<sys:Double>0.3</sys:Double>

</DiscreteObjectKeyFrame.Value>

</DiscreteObjectKeyFrame>

</ObjectAnimationUsingKeyFrames>

Another way to do this is to use double animation:

<DoubleAnimation Storyboard.TargetName="somePart"

Storyboard.TargetProperty="Opacity" To="0.3" Duration="0:0:0"></DoubleAnimation>

<DoubleAnimationUsingKeyFrames Storyboard.TargetName="OuterBorder"

Storyboard.TargetProperty="Opacity" Duration="0:0:0">

<DiscreteDoubleKeyFrame KeyTime="0:0:0" Value="0.7" />

</DoubleAnimationUsingKeyFrames>

If you have further questions please feel free to ask.
