RadDatePicker+ajax

[lnu]

Hello,

I'm creating dynamically some web users controls which contains a RadDatePicker. I'm using the DayRender event to disallow weekend selection. When doing full postback everything works fine, but If I use ajax(AjaxPanel or AjaxManager) I can select the weekend.

sample:

 <telerik:RadAjaxPanel runat="server" ID="panel1">
         <telerik:RadDatePicker runat="server" Visible="false" ID="dp1">
         <Calendar OnDayRender="dayRender"></Calendar>
         </telerik:RadDatePicker>
         <asp:Button runat="server" ID="btn1" OnClick="btn1_Click" />
</telerik:RadAjaxPanel>

 protected void btn1_Click(object sender, EventArgs e)
        {
            dp1.Visible = true;
        }

        protected void dayRender(object sender, Telerik.Web.UI.Calendar.DayRenderEventArgs e)
        {
            if (e.Day.IsWeekend)
            {
                e.Day.IsSelectable = false;
                dp1.Calendar.SpecialDays.Add(e.Day);
            }
        }

Am I missing something?

Best regards,

Laurent

I don't think the answer matches the question.

to be clearer.

I take your sample http://demos.telerik.com/aspnet-ajax/ajax/examples/common/showingwebcontrols/defaultcs.aspx.
I add a dayrender events to disallow weekend selection of the radcalendar1. You still can click on the weekend. On the opposite, if you remove the radajaxmanager, it works as expected.

 <telerik:RadCalendar ID="RadCalendar1" runat="server" EnableMultiSelect="false" Visible="false" AutoPostBack="true" OnSelectionChanged="RadCalendar1_SelectionChanged" OnDayRender="dayRender" />

protected void dayRender(object sender, Telerik.Web.UI.Calendar.DayRenderEventArgs e)
        {
            if (e.Day.IsWeekend)
            {
                e.Day.IsSelectable = false;
                e.Day.IsDisabled = true;
                RadCalendar1.SpecialDays.Add(e.Day);
            }
        }

Could you have a try and tell me if I'm wrong?

Hello,

I'm still stuck. None of your links match the problem here.
In fact, the datepicker is added dynamically on a button click registered in a radajaxmanager.
The point is the "DescribeComponent" method of the calendar is called before the dayrender event.
The days added to the specialddays collection in the dayrender event are never written.
 In a non ajax scenarion, everything works as expected but in the ajax scenario the ProxyScriptControl comes around and calls the describecomponent method of each child, and thus my calendar.

Do you have a workaround for this case?

Best regards,

Laurent

Hi lnu,

I tested the provided code and disabling weekend selection of the RadCalendar1 is not working properly even if I set EnableAJAX property of RadAjaxManager to false.

However I suggest you examine this code library which elaborates on this subject and let me know if it helps.
