Hi,

I have a page wich contains left a radgrid with about 750 records (no paging) and right a formview.
The formview is databound on the radgrid, so when you select a row in the radgrid the formview refreshes with the selected record.

Pretty basic so far.

Now when i initialy load the page it takes about 3 seconds for everything to load.
Then, without the ajax it takes about 3 seconds for page to reload after i select a row in the radgrid. As you expect the whole page is reloaded. Something we dont want.

Now i added an Ajax manager in the hope i could cut down on this load time. I set the ajaxmanager so that for request on the radgrid it should only refresh the formview.
But this seems to make the application run slower! It now takes about 5 to 10 seconds for the formview to refresh.
What did i do wrong?

Anybody an idea,

Regards,
Jelte

Hello Jelte,

Tips on how to optimize the RadGrid performance and your page overall performance can be found in the resources pointed below:
http://www.telerik.com/help/aspnet-ajax/gridoverview.html (Chapter 'Performance tips and tricks'
http://www.telerik.com/products/aspnet-ajax/resources/top-performance.aspx
http://www.telerik.com/support/aspnet-ajax.aspx (Section "Performance")

They can help you reduce the loading time of the browser.

Hi Pavlina,

thank you for your response.

I had already read most of what you suggested prior to posting here.
But it seems nothing helps.

as far as i can see it, the radgrid is being databound everytime it is clicked.
This shouldnt happen.
It should only update the formview.
I have already turned caching on on the datasource.

thank you,
Jelte

Hello Jelte,

To further track the issue, it will be best if you open a formal support ticket, and send us a small working project, demonstrating your logic, and the performance issue. You could open a formal support ticket from your Telerik account and attach a ZIP file there. In that way we can reproduce and pinpoint the problems you are facing on our side and provide a solution.

All the best,
Pavlina
