FadeTransition problem

[Gunnar]

I have a Grid in a TransitionControl and I want it to fade in or out depending on the Visibility property.

this.LicenseDetailsTransitionControl.PrepareAnimation();
if (this.LicenseDetailsGrid.Visibility == Visibility.Collapsed) this.LicenseDetailsGrid.Visibility = Visibility.Visible;
else this.LicenseDetailsGrid.Visibility = Visibility.Collapsed;
this.LicenseDetailsTransitionControl.StartAnimation();

<telerik:RadTransitionControl x:Name="LicenseDetailsTransitionControl"  Grid.Row="4" Margin="3" Duration="00:00:01.00"  Padding="5" >
    <telerik:RadTransitionControl.Transition>
        <effects:FadeTransition  />
    </telerik:RadTransitionControl.Transition>
    <telerik:RadTransitionControl.Content>
        <Grid  x:Name="LicenseDetailsGrid" Height="400" >
...

When I set Visibility = Visible, the Grid fades in nice and smooth as it should do.
When I set Visibility = Collapsed, the whole Grid first seems to be squeezed into one row and then it fades out.

Why?

Hi Gunnar,

I can suggest you do the following:
- instead of a Grid as a content of the TransitionControl you can use UserControl and set its Content property to be the Grid.
- instead using the Visibility property, I can suggest you to set the Content of the UserControl to null.

Hope this makes sense. Please let us know if that worked for you.

Kind regards,

I found the same problem and I was not able to solve it either by setting a UserControl as the root content for the transition as you suggested...

Hello Mrn,

Could you please give us some more details what exactly is going wrong? Also, are you using the latest available version? If not, which one are you using? Would it be possible to send us some code snippets or ideally a sample project and more details what exactly you are trying to achieve. In that way we will be able to provide you with the best solution for your case.

Looking forward to your reply.
