Hi Team

We have removed the AjaxControlToolkit reference as it is no longer required from our solution.  However, one file, where no changes were made, is now breaking, after we removed the AjaxControlToolkit package. This file uses the Telerik RadCalendar control and is breaking during initialization.

Interestingly, the error disappears when the AjaxControlToolkit package is re-added.  The following error is noticed when toolkit package is removed ,

Uncaught TypeError: Cannot read properties of undefined (reading '_events')

The corresponding ajax and vb file is uploaded here for review.

datePicker.Calendar.ClientEvents.OnLoad = initMethodName;

Hi,

We have upgraded the current 2013 Telerik version to Telerik AspNet Ajax Net45 2021.2.616. Following the upgrade the RadDatepickers have stopped working. Although the calendar popup appears as expected, if a date is clicked (whether it’s on a date or empty cell) the popup closes.

Whilst looking into this we noticed that the older version has a click event attached to the RadCalendarPopup which does not get added when the 2021 version is used. 

The RadDatePicker control used for testing

<asp:Panel id="Wrapper" runat="server">
    <telerik:RadDatePicker ID="RadDatePicker" Style="display: none;" MinDate="01/01/1900" MaxDate="12/31/2200" runat="server" Skin="Cse" EnableEmbeddedSkins="false">
        <Calendar ShowRowHeaders="False" FastNavigationStep="12"></Calendar>
        <ClientEvents OnDateSelected="TelerikRadDateTimePicker_DateSelected" />
    </telerik:RadDatePicker>
</asp:Panel>

The OnDateSelected is fired when the Go button is clicked. The onClosing method used sets the event. set_cancel() to true.

A screenshot attached

• RadCalendarPopup in version 2013
• Version 2013 Scriptresource snippet
• RadCalendarPopup  in version 2021
• Version 2021 Scriptresource snippet

The 2021 version has wrapped the div click event in an If condition which we are unable to satisfy to get the click event added to the RadCalendarPopup div. Due this the calendar click event is treated as a document click event which closes the popup.

Could you please explain why the click event is wrapped around the If condition and help us find a workaround for this.

Thanks

How Can I Set Date Filter Like this in RAD GRID AJAX ( ASP.NET C#)

Please Ref . Below Image

Hello Telerik-Team,

Could you tell me, how I can change the title text of the time selection?
I want to translate it to my language. I added a screenshot, where I marked, what I mean.

Regards

How do i remove the 'Summary' and 'Cellspacing' attributes from the Timeview? This is causing my website to not validate through https://validator.w3.org/.

I have tried setting summary="" and cellspacing="-1", gridlines="None", but nothing happens. I think your 'Summary' attribute is broken.

Hello, please open a demo page https://demos.telerik.com/aspnet-ajax/datetimepicker/overview/defaultcs.aspx?skin=Bootstrap and select Bootstrap skin.

Note that the left top & bottom corners are not rendered correctly. Most likely it's related to the "box-sizing: content-box".

How set default time like "00:12:00" in RadDateTimePicker?

I have set TimePopupButton-Visible="false" and only want to select the date...
