[Solved] more on the whole memory leak thing with SL 4...

[Giancarlo Aguilera]

hello,

first of all, thank you for being proactive on the whole memory leak thing with SL4. i downloaded the latest version of the telerik tools and it appears the issue with the inline datatemplates is no longer a problem with radgridview.

i am having another problem now though. please see the xaml below. This is the XAML for radgridview column. In the first couple of lines notice how I am setting the column's header to some content. This content contains a button with an event handler. Currently this button is commented out. However if I put the button back in there my app continues to leak and it appears to leak as a result of the event handler. I have attached a screenshot of an object retention graph produced by the profiler I am using. If you take a look you will see that the EvenCrewSheetMemberGridView is the instance being retained and this instance contains the XAML below. If I comment out the button, then I no longer have a leak. I am not sure who needs to fix what. Do you know if there is something I am doing wrong? Is this yet another SL4 memory leak? Or is this an issue with Telerik? Any ideas are greatly appeciated. Thanks again

Hi Giancarlo,

 You will need to remove the event handler by your own since the grid cannot know (and remove) this handler.
