When MultiViewColumns > 2 the the month views of the Calendar are not aligned properly. The problem occurs if the week count in the months is different and the ShowOtherMonthsDays property is set to false.

RadMonthYearPicker is missing form the SkinManager's ControlTypeToApplyskin collection

As I'm using RadDatePicker in my Grid,

In RadGrid for the first time, the image beside the calendar control renders as expected.

As soon as I enter into "InLine" edit mode there would be 2 images rendered beside the control.

And after clicking on cancel there is no change in the image beside the control.

Also attached the screenshot for the same.

Put more than two RadDatePicker with single SharedCalendar on page. some RadDatePicker are in side of UpdatePanel with a button in it. when I press that button RadDatePicker behaviour is strange. 
RadDatePicker inside UpdatePanel not opening Calendar popup while RadDatePicker outside UpdatePanel opens calendar popup but gives javascript error on any date selection. the javascript error is "Unable to get property '_selectedDates' of undefined or null reference".
It looks like it is destroying shared calendar object on partial postback.
Please find below sample code to replicate the issue. after clicking "Submit" button, it doesn't open calendar popup for "Date 2" and for "Date 1" it opens but doesn't allow to select date and gives JavaScript error.

----------------------
<asp:ScriptManager ID="sc1" runat="server" />
<telerik:RadCalendar ID="dtCal" runat="server" EnableMultiSelect="false" />
Date 1:
<telerik:RadDatePicker ID="dt1" Width="103px" runat="server" SharedCalendarID="dtCal" />
<hr />
<asp:UpdatePanel runat="server" ID="up">
	<ContentTemplate>
		Date 2:
		<telerik:RadDatePicker ID="dt2" Width="103px" runat="server" SharedCalendarID="dtCal" />
		<br />
		<asp:Button runat="server" ID="btnDT" Text="Submit" />
	</ContentTemplate>
</asp:UpdatePanel>
----------------------

When i add all controls in UpdatePanel it works properly. but Actual code is much more complex than above sample with too many lines of javascript code and many date pickers on single page and simply all Calendar and DatePicker controls can not be moved in UpdatePanel.

Improve the use of HiddenField inputs' values.

-> When DatePicker renders for the first time, it applies the CSS according to the selected skin.

-> But as soon as I enter into an edit mode or insert than the CSS is not applied to the control and the design of the RadCalender is breaking somehow.

-> Also entering into edit or insert break the design of the other RadCalender control placed in filter panel.

Hi everyone. I got an issue when I used RadCalendar under IE10. There is a big blank area on the right of this control after I clicked next month or next year for navigation. But it displayed OK under Firefox.
Does anyone get this problem? Is there any solution to fix it?  
Thank you.

I placed a RadMonthYearPicker on my page.

<telerik:RadMonthYearPicker DateInput-DateFormat="MMMM, yyyy" DateInput-DisplayDateFormat="MMMM, yyyy" Skin="MetroTouch" ID="MYPickerEnd2" CssClass="MYPickerEnd2" runat="server" />

var monthyearpicker = $find("<%= MYPickerEnd2.ClientID %>");

I am getting null every time.

On my page I am getting this as the client id: ctl00_MainContent_AnalyticOutline_MYPickerEnd2

I was going to use javascript to open the RadMonthYearPicker when clicking on some specific text on our page.

Hi,
Reported & Replicated so far on IE 9.
I have an APS.net user control containing 2 RadDateTimePickers.

The UI gets screwed on IE 9 on first load. (Screenshot attached) Icons become available when we click on Calander icon link for 2-3 times and then after it is available on subsequent loads in same scenario.

I am the one who recommended Telerik in my team and our implementation is pending just because of this as many of our clients use IE 9. Please fix ASAP or suggest simple work around.

Thanks,
Piyush

When the FastNavigationPrevImage and NavigationPrevImage properties are set the font-icon based buttons are replaced with image buttons. However, the Prev and FastPrev-related images are missing the required float: left CSS setting and are rendered in the center of the calendar title bar.

RadCalendar and RadDatePicker cannot pass the following check by https://achecker.ca/checker/index.php

WCAG 2.0 guideline
Section

1.3 Adaptable: Create content that can be presented in different ways (for example simpler layout) without losing information or structure.
Success Criteria 1.3.1 Info and Relationships (A) 

Check 245: Data table with more than one row/column of headers does not use id and headers attributes to identify cells.

Repair: Add id and headers attributes to table cells so they identify the cells that relate to the headers.

=======================================

WORKAROUND:

$telerik.$("table.rcMainTable tbody th").each(function (idx, el) {
    var thId = $telerik.$(el).attr("id");
    $telerik.$(el).siblings("td").attr("header", thId);
})

When using min/max date the invalid dates have almost identical styling as the valid ones, this makes it hard for the user to see what dates are valid.

It would be nice of there was some way of telling them apart except by hovering over them.

Also when using "metro theme" the invalid date overrides the styling for dates belonging to "other month".

Workaround 1) Use .resx files as the attached ones 

Workaround 2) Set properties to ViewState
        RadMonthYearPicker1.MonthYearNavigationSettings.ViewState["_mCancelButtonCaption"] = "my cancel";
        RadMonthYearPicker1.MonthYearNavigationSettings.ViewState["_mTodayButtonCaption"] = "my today";
        RadMonthYearPicker1.MonthYearNavigationSettings.ViewState["_mOkButtonCaption"] = "my ok";
