    Are there any limitation in using RadAjaxManager?
    I am getting “A script on this page is causing your web browser to run slowly .  If it continues to run, your ccomputer might become unresponsive.” Stop running this script issue.

    I have a page that is created with all RadControls. Ie., RadTextBox and RadComboBox etc. On my page, I have 2 RadPans. “Mainpan” is for data entry which has RadTabStrip and RadMultipageView and a RadGrid.  “Right pan” holds RadPanelBar which is being used as menu.  

        1) On data entry (MainPan), I needed the Ajax functionality for some of my data elements. Example: State and city. If user selectes state, the city drop down should get the list of cities for the selected state. I have added AjaxSettings for those controls. The functionality works good for the controls.

        2) Now I need Ajax functionality for RadPans. Basically, when user chooses an option from RightPan (RadPanelBar) - menu, I would like to perform database action and show the changes in mainpan – data entry screen. I have added asp panels/RadAjaxPanel in side each RadPans. Added these panels as part of RadAjaxManager.

    Now I am running into the problem, during the data entry. When I choose the State, the process takes long time and I am getting “A script on this page is causing your web browser to run slowly .  If it continues to run, your ccomputer might become unresponsive.” All of the elements that i have on the data entry screen which are part of RadAjaxManager are acting the same way. 

    I need both the functionlaities. How can I achieve this? Are there any limimations on using RadAjaxScriptManager?

    Thanks in advance.

    Hello usr9999,

    We have a lot of optimization techniques for RadControls and I am sure some of them will be of great help for your project.
    Optimizing output, page load time and the overall performance of RadControls for ASP.NET AJAX
    Optimizing client-side performance
    RadControls for ASP.NET AJAX - Top Performance

    Give them a try and let me know if the issue still persists.
