Dear Telerik Team,
We are very disappointed to write this mail. We are using Telerik RadControls for ASP.NET since last 4 years, we were happy to use your controls except in some scenarios related to performance. Intermittantly at some extent it degrades its performance.
Considering above fact in mind still we were suppose to go ahead developing our new big and our dream product on internet. However we have been observing a very degradbale performance of new radcontrols on your demo site itself. We are also afraid to see comments on different sites by users on internet relates such low performance and quite confused what to do ?
And coming to us it is very important decision to select controls before starting developement, we cannot roll it back.
1. What is the cause new radcontrols degrades the performance ?
2. Are you going to work on this issue ? Is it a known issue ?
3. What is an alternative to overcome such performance issues ?
4. Will it work with same performance with cross browsers ?
I hope your honest reply will help me to arrive our decision whether to go ahead with RadControls ?
