Memory Errors with Gannt Chart

[Jeffrey Gilliam]

In our web-based ajaxed application is a page that we know is going to be a resource hog and very slow to render; it contains a large dynamically-generated HTML table, a Telerik Gantt chart and a Telerik bar chart. (Too much for one page, but it’s what our customer wants.) In the past week we have been getting one of two errors (see below) on this page when the size of a Gantt chart gets large, beyond several hundred lines. This has been rendering successfully, slowly but successfully, until this week.

We recently upgraded from Telerik version 2010.1.309.35 to 2010.2.715.35. So, our first attempted solution was to revert the application to the previous Telerik DLL, but seems to have had no effect. Our next attempted solution was to increase the memory on the IIS server. This too had no effect.  We are exploring other IIS settings for memory management, but want to run these errors by you folks to see if you can offer any insights.

Hi Jeffrey Gilliam,

What is the render size of the chart image in pixels? Does changing it have any relation to the error or just the number of series items being drawn? Also, how many series are being rendered with the chart and how many items does each have?

Kind regards,
Vladimir Milev

Vladimir,

Your are going to cringe, but the width of this chart is 2650 pixels! This is being driven by a customer requirement for a very detailed data display above this Gant chart. The height of the chart is dynamic, but gets large also with this particular data source: approx. 900 items with 7 series per item. I suspect we are hitting limits in all three categories. If I reduce any of these numbers the chart does render without errors, unfortunately the number of items and the series are being driven by data and the reqs to display that data. I am hoping to reduce the width but if I can't, I'm looking for other approaches.

Thanks,

Jeff

Hello Jeffrey Gilliam,

By default RadChart uses the Session to store the image which means this is the probable offender in the case. I suggest you give UseSession=false a try. Also, you may consider storing the session in a database (sql). I believe these are two good starting points to work from. I hope this helps.

Best wishes,
