Memory Leaks?

[Steve Bywaters]

I find that whenever I use RadTabStrip + RadMultipage in a complex FormView, I get:

1. Slower and slower response inside VS2008...
2. Memory bloat - up to about 1Gb used - then...
3. VS crashes (3 times this morning!! Each after use of 1Gb memory)

I only seem to have this problem when using these components in a complex form - otherwise VS etc is quite stable

Ideas?

XP SP3 (4Gb ram)
Telerik 2010 controls
ASP.NET 2.0/3.5

Hi Steve,

We were unable to confirm any link between using the RadTabStrip control and the VS memory usage in our tests. Can you please send us a test project/page that we can use for testing?

Also, can you try disabling all add-ons like ReSharper and others. Does this improve the memory usage?

All the best,

Ok, I've uploaded the page I'm currently working on, plus the required Master page and style sheet.

Simply open up the page in VS2008, go to the FormView ("fvEdit"), set it to open the EditItemTemplate, and start working there (where most of the controls are, within a table) .
Edit some controls, move them around, close the template, re-open the template, etc, etc, etc
Do all the stuff you would do when building up a reasonably complex form.

In my work here, Task Manager showed VS memory use going from an initial 200M or so up to 1G+ in about an hour!
(Then 'bang', as VS falls over)

And here we go with the memory blow-out:

It took me 2 hours to get there - working on the form all the time.

..and here we go again... < 1 hour later!

Hi Steve,

I tested the page and indeed Visual Studio's memory usage gradually grows, but I also tested the same page with the TabStrip and PageView removed and editing the template through the Design mode still causes Visual Studio's memory usage to grow. I don't think this is exactly a memory leak - Visual Studio has some known problems with memory fragmentation and it seems that the amount of Controls/markup causes the memory usage to skyrocket in this case.

I suppose it is true that my biggest forms do always use TabStrip...

So if you're 'pointing the finger' <g> at VS08, do you know if this is improved in VS 2010?

Hello Steve,

I haven't done any 'scientific' tests with VS 2010, but I feel the performance is greatly improved and I prefer it over VS 2008 for my day-to-day work whenever possible. You can always download a trial version to test your scenario.
