Hi,

I am using TabControlExt with 2 tab items in my application. I got the below memory leak only when I switch between tabs and close the tabconrol.

System.Object[]
Syncfusion.Windows.Tools.Controls.TabControlExt
System.Windows.EffectiveValueEntry[]


Please find the attached project solution and kindly let me know what is the issue with TabControlExt when we switch between the tabs.

Thanks,
Swamy.

Hi Rajesh,

After closing the TabItemExt, TabItemAutomationPeer will hold the instance of TabItemExt and it should be forced to release the memory using FakeWindowAutomationPeer. We have modified the sample for the same and you can download it from the following link:

Sample: Memory_leak_AutomationPeer
