Hi,
In deffered scrolling the scroll bar moves there is a continous request for data. Is there a way to request for data only when the scroll bar is stopped at a particular location ans not while it's moving?
Thanks,
Sayali
In addition to the above mentioned question Im having a lot of performance issues as well its taking around 3 seconds to load 100 rows of 5 column data. Even if I change the number of rows to a lower count it still takes as much time. Though if i reduce columns it works faster. For example with a single column is takes 700 millisecods, with 2 columns around 1.3 seconds. Is there any way to increase the performance?
Deferred scrolling will continue to access the data rows, there isn't a way to have it not make requests while its moving.
As for your performance question.
It shouldn't be taking anywhere near that amount of time, especially with only 5 columns and 100 rows.
Area all 100 rows visible?
Can you post your sample?

Hi Steve,
I have modified the existing sample which came with the installation(startup solution). I did a few changes to it. On the server side I have 1 million records now and each record with 5 columns. If you will go to the visualization link I have added a small time which appears at the top of the grid. I have added the modified files. Let me know if you need the whole sample.
Let me know if I'm missing something.
Hi Again,
I forgot to mention for the virtualcollection the loadsize is 5000 in the file attached. But I have even tried decreasing the load size to 100 or even to 12 but still the time remains the same around 3.2 seconds.
I have found the solution to the issue. It had to do with the WCF service. I'm sorry for the incovenience caused. And thanks for your help.
