    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

    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
