Memory leak ?

[Jean Ressouche]

Dear Telerik team,

i have a memory leak issue when using the RadTransitionControl with version 2011.1.419.1040.

Here is the XAML, used into a empty usercontrol:

<Grid x:Name="LayoutRoot">

        <telerik:RadTransitionControl x:Name="LblEffect">

 

    <telerik:RadTransitionControl.Transition>

              <telerik:RollTransition />

    </telerik:RadTransitionControl.Transition>

 

    <telerik:RadTransitionControl.ContentTemplate>

           <DataTemplate>

                  <TextBlock HorizontalAlignment="Stretch" Foreground="White" Margin="5" Name="lbl_status" Text="{Binding Content, ElementName=LblEffect}" VerticalAlignment="Center">

                       <TextBlock.Effect>

                            <DropShadowEffect Direction="0" ShadowDepth="1" BlurRadius="4"/>

                       </TextBlock.Effect>

                  </TextBlock>

           </DataTemplate>

     </telerik:RadTransitionControl.ContentTemplate>

 

      </telerik:RadTransitionControl>

       

    </Grid>


 In my .cs code, i have a DispatcherTimer, with this code :

public void SwitchTick(object o, EventArgs sender)
{
    if (DataContext != null)
    {
        LblEffect.Content = null;
        LblEffect.Content = ((ItemsClass) DataContext).Status; // (Status = simple String value)
    {
}

Do you think that my way is incorrect ? (to change the RadTransitionControl.content directly in the code etc..) 

• The leak is really important (1Mo/s under normal usage, with 15 instances of this usercontrol on screen)
• If i remove the RadTransitionControl, i don't leak at all
• I want to keep the cool effects :D

Thanks in advance !

Hi Jean,

 We are not aware of memory leaks in the Docking control. Unfortunately I couldn't understand from the code you sent how do you test for memory leaks. Could you please share with us what makes you suspect that there is a memory leak related to this control and how do you test for memory leaks? If you could send us a sample project that reproduces the problem and some steps that will let us observe the problem this would help us investigate the problem and help you resolve it.

Best wishes,
