I've developed an application with telerik controls. My simple form having only two text boxes and a radgrid with only 2 columns take 8sec to load and on each post back request this time increases. even if i only refresh the page again and again its loading time increases.
i have some very large forms which have a no of controls with 2 or 3 grids and this issue become so worst there
while we see demo of Telerik its speed is good i dnt know what i am missing
i m using shared hosting application is running with good speed locally but have very slow performance on shared or dedicated host. i check it on both host
i think i have some thing missing
I've added the radScriptManager  to the page.
I have set debug mode=false in web.config 
but ..does not seem to help.
Please help me for performance issue as soon as possible

Hello,

By using Custom paging, it is possible to fetch only a fixed number of records and perform operations over this specified set of data. Telerik RadGrid allows such data manipulation through the custom paging mechanism integrated in the control.

Checkout the following link for more information about custom paging in RadGrid.

Custom Paging

I hope the following links also would be of help in improving the performance of RadControls for ASP.NET AJAX:

Thanks for immediate response but i have already read these articles
i am already using custom paging in rad grid
i want to know whether the use of ajax panel can fast the app
when we specified Ajax control id and updated controls in RadAJAXManager what it actually done is it do partial postback or poast back whole form
When should we use AjaxPanel?

Hi Saima,

The RadAjaxManager control allows you to easily create settings that update many controls on the page. Having a large number of updated controls can both help with a performance problem by rendering smaller portions of the page and worsen the situation by triggering unnecessary DOM layout updates.

You can review the following links for additional information:

Manager vs. Panel
