Chrome and Edge out of Memory Error With Multiple AspNetPanels


Hi Support,

We have a Dashboard control which we use to display a number of DevExpress charts and Widgets.  We are using the Devexpress WebChartControl so we embed these inside individual AspNetPanels.

Originally I was thinking this was a browser issue but I’m not convinced anymore as we are doing the exact same thing in our VWG application and dont have the issue.

Essentially every few minutes we update the data on the chart by calling panel.Recreate();

This all works perfectly except after a few hours I get an Out of Memory error on both Chrome and Edge.  Our VWG version runs continually without issue.

The Panel is created at Design Time as an FYI.

Any ideas as to why this would be causing an OOM error in WiseJ?

Don’t use panel.Recreate(). It recreates the javascript class on the client and unless you dispose the devex control you leak. Use Update() to simulate the aspnet page cycle.

VWG doesn’t use javascript classes and its aspnet integration was running out of viewstate space all stuffed in the headers, which is the wrong usage of headers.
