    Hi,

    We are using the Telerik controls version 2012.3.1308.40(licensed) on our web site. We are using the RadAjaxManager in almost all pages with RadAjaxLoadingPanel.

    We initially had pagination in all rad grids. But the user does not like the pagination and wanted to use the scrolling instead. So we removed pagination from all grids and enabled scrolling,
    <ClientSettings>
        <Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="true" />
        <ClientEvents OnGridCreated="GridScrollCreated" />
    </ClientSettings>
    We have some grids with item template to capture user input (3 columns only). Approximately we may get 200 to 300 records from the database when binding the grid. After making this change, we have encountered a new problem that our application become very very slow. For each post backs the loading panel is running for more than 3 minutes. After the post back the grid is not rendering properly and further post back are not working.

    please see the attachment

    Hi Srikrishnan,

    In case you need to implement radGrid control it bit amount of items without enabling the basic paging mechanism I would suggest you to use the new virtualization feature of the control. See the online demo below:
