Hello Sylvester Bos,
First off, I'd like to apologize for the delay in my response.
Regarding the issue you described - it is possible that the heavy content of your smart part (RadGridView
with 6000 rows) causes the effect that you are observing.
The upcoming Q1 2008 release will feature a re-engineered RadGridView
control that will be much faster and more stable. I encourage you to take a look at the beta that we released a couple of weeks ago to get an idea of the performance improvements.
If you are still interested in TCEK I will gladly help you to further investigate your issue. But to be able to do that I will need additional information about the order of loading and displaying your smart part. With this information I will be able to reproduce your scenario locally and identify the reason for this issue.
A code sample will be best, but if you can not send code I suppose that a list of steps will be fine.
I'm looking forward to your response.
