We are using VWG version 6.4.0 and we use moslty just VWG controls, but also devexpress controls. Our performance problems happen mostly on complex forms, where we load many user controls (with VWG controls), but we also have this on devexpress AspxScheduler control. When we type in a textbox, there are some delays until the characters appear. We observed this behaviour only on slow processors.
We have sent a sample application to illustrate this. This is based on the devexpress AspxScheduler control. Here we had a delay in showing characters right from the start, and iexplorer.exe takes 100% of one core. We compared this with the sample from http://demos.devexpress.com/ASPxSchedulerDemos/Templates/DateHeaderTemplate.aspx , where we did not have this behaviour, and there was almost no CPU usage.
Any suggestion is very much appreciated!
Thanks and best regards,
