    Hi everyone,
    Currently I have around 450 rad comboboxes inside radgrid on web page. The number of comboboxes may increase to any number in future. Issue is the loading of the web page which is taking sometime for current situation. So it will be a big problem in near future when number of comboboxes increases.
    Please help me in this with code or any configuration to be done to handle the performance issue.
    Thanks in advance.

    Hello Anirud,

    The best approach to optimize the performance speed of Telerik RadComboBox  is using the load-on-demand feature. The load-on-demand mechanism loads the items only when the user types or clicks in the field or the drop-arrow image. It filters the Items server-side before they are loaded in the control and the Filter feature performs filtering at client-side.
    And I recommend you to retrieve data in portions - with use of ShowMoreResultsBox and VirtualScrolling options.

    Take a look at the this demo which demonstrates the various Load On Demand Modes.

    Thanks,

    Shinu.

    Hi Shinu,
    Thanks for your response and help. But its not about loading of items in combobox. In my case, no. of items in combobox are fixed and are not going to increase rather it is the no. of comboboxes on web-page which is the problem. More is the no. of comboboxes on page, more is the performance drop of page. So i need help regarding the loading speed of page not combobox.
    Thanks
