__doPostBack function

[Cemka]

Hello,
I have an ASP.NET Ajax Calendar, with AutoPostBack = false
When client change viewed month I use this event : ClientEvents-OnCalendarViewChanged="postBack"
To call this Javascript function :
           

function postBack(sender, args) {
__doPostBack("<%= RadCalendar1.UniqueID %>", "myArgument");
}

Here is my Page_Load function :

protected void Page_Load(object sender, EventArgs e)

        {

            if (!IsPostBack)

            {

                RadCalendar1.SelectedDate = DateTime.Today;

            }

            else

            {

                string eventTarget = (this.Request["__EVENTTARGET"] == null ? string.Empty : this.Request["__EVENTTARGET"]);

                string eventArgument = (this.Request["__EVENTARGUMENT"] == null ? string.Empty : this.Request["__EVENTARGUMENT"]);

                if (eventArgument.Equals("myArgument"))

                {

                    RadCalendar1.SelectedDate = DateTime.Today.AddDays(-10);
 // Just for test

                }

            }

 

            FillHolidayDataset(RadCalendar1.SelectedDate);

        }

The problem is when I change month, I Have this error :

Invalid navigation argument: [myArgument]

[ApplicationException: Invalid navigation argument: [myArgument]] Telerik.Web.UI.RadCalendar.RaisePostBackEvent(String eventArgument) +864 Telerik.Web.UI.RadCalendar.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +13 System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13 System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +176 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +5563

What's wrong with my doPostBack function ?

Hello Cemka,

You can invoke the ajaxRequest from the function instead of __doPostBack.
aspx:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
</telerik:RadAjaxManager>

javascript:

function postBack(sender, args)
{
var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");
ajaxManager.ajaxRequest("myArgument");//Making ajax request with the argument
}

Thanks,
Shinu.

Thank you for your answer.

What is RadAjaxManager1_AjaxRequest ?
(because I have an error with your code ...)
