    Hi all,

    I have this scenario:
    - MasterPage with left side menu,
    - center  RadAjaxPanel,
    changing selection on left menu tree change content of the center page.
    Also controls are loaded dynamically. I want handle errors accoured on server by displaying usercontrol. .
    I try'd use  RadScriptManager.AsyncPostBackError and here load my usercontrol with error information, but no luck, Js exception is thrown

    PageRequestManagerServerErrorException

    with error from server. 

    EnableEventValidation is set to "false" on the my MainPage.aspx

    Thanks in advance rafalr

    Hi Rafal,

    The provided information and the error description are rather generic so it  is heard to determine what exactly is causing the issue. Could you please share your application markup as well as the related code behind so that we could further assist?

    Hi Maria,

    I need solution to display server error, i have partial page rendering, also i try to bind RadScriptManager to AsyncPostBackError event.
    Everything work fine, i can display error message on client side using alert or div.
    Is it possible to load custom usercontrol with error description on    AsyncPostBackError event ?
     
    protected virtual void ScriptManagerAsyncPostBackError(object sender, AsyncPostBackErrorEventArgs e)
            {
                
               LoadUserControl(pathtoErrorControl);
               Server.ClearError(); // to not call global.asax application error
            }
    private void LoadUserControl(string ucCtrlPath )
            {
                ctrl = LoadControl(ucCtrlPath);
                RightPane.Controls.Clear();
                if (ctrl != null)
                {
                    string userControlID = ucCtrlPath.Split('.')[0].Replace("/", "").Replace("~", "");
                    ctrl.ID = userControlID;
                    if (ctrl != null && RightPane.Controls.Count == 0)
                    {
                        RightPane.Controls.Add(ctrl);
                    }
                }
            }
