Fluid and Elastic Capabilities

The RadCalendar including the picker controls provide elastic and fluid capabilities which allow keeping the control’s component proportion on different mobile devices.

note

As of 2016 Q1 SP1 RadCalendar takes the font-size of the page automatically. If the developer does not set it explicitly (Example 1), this is up to the client's browser and a common default value is 16px.

Example 1: Setting default font for the page with the default value for the Telerik controls.

body {
    font-size: 20px;
    font-family: "Segoe UI", Arial, Sans-serif;
}

Fluid capability

The fluid capabilities are simply achievable by setting the control’s width in percentages.

Elastic capability

To take advantage elastic functionality advantage you could set a specific font size based on the application target mobile device and follow three simple steps to transform the RadCalendar/Picker controls to be elastic:

  1. By using specific CSS selectors apply "1em" font size for all the Calendar components like this:

    <style type="text/css">
    /*Calednar*/ html .RadCalendar,
    /*MonthYearPicker, RadDatePicker FastNavigation Popup*/ html .RadCalendarMonthView,
    /*TimeView Popup*/ html .RadCalendarTimeView,
    /*Input, DateInput*/ html .RadInput, html .riTextBox,
    html .RadPicker {
        font-size: 1em;
    }
    </style>
    
  2. Set the RenderMode property of the Calendar, DatePicker, DateTimePicker, MonthYearPicker controls to "Lightweight"

    <telerik:RadCalendar ID="RadCalendar1" runat="server" RenderMode="Lightweight" AutoPostBack="true">
    <SpecialDays>
        <telerik:RadCalendarDay Repeatable="Today" ItemStyle-CssClass="rcToday"></telerik:RadCalendarDay>
        <telerik:RadCalendarDay Repeatable="DayInMonth" Date="6/19/2014" ItemStyle-CssClass="rcSelected"></telerik:RadCalendarDay>
        <telerik:RadCalendarDay Repeatable="DayInMonth" Date="6/17/2014" ItemStyle-CssClass="rcHover"></telerik:RadCalendarDay>
    </SpecialDays>
    </telerik:RadCalendar>
    <telerik:RadCalendar ID="RadCalendar2" runat="server" RenderMode="Lightweight" AutoPostBack="true" MultiViewColumns="2" MultiViewRows="2">
    </telerik:RadCalendar>
    
  3. Set the picker components width in "em". In order to keep the default calendar/pickers proportion on mobile devices we would suggest you to set width="13.3333em" as the default width of the components is "160px" and the font-size is originally set to "12px"See the both images bellow that presents the control's elastic capability

    • DatePicker control's rendering in case the body font size is set to 12px
      mobile-support-12px

    • DatePicker control's rendering in case the body font size is set to 18px
      mobile-support-18px
