  Using C1Calendar from C1.Web.Wijmo.Controls.48.dll
  
  Changes C1Calendar from 2010v1 to 2025v2 399 control.

  Now those properties not appears:

  AllowQuickPick="true"
  
   calendarDate.SelectionMode = C1.Web.UI.Controls.C1Calendar.SelectionMode.Day;

         DropDownButtonAlign="Right" PopupPosition-At-Left="Right" />
  	   
       <%--                    
  		  AllowQuickPick="true"

  Hello Enrique,

  Both properties are still present in C1Calendar:

  • AllowQuickPick
  • SelectionMode

  Please refer to the attached sample with implementation. (see C1Calendar_Sample.zip)

  Whats means is SelectionMode with Month = true?

  <SelectionMode Month="True" />

  Hello Enrique,

  Please refer to the documentation for this information: https://developer.mescius.com/componentone/docs/webforms/online-calendar/selectingcalendarmon.html

  Note that Day and Days are by default true and others are false. So, if you want to enable only Month selection, set Day and Days to false.

  <wijmo:C1Calendar ID="C1Calendar1" runat="server" AllowQuickPick="true" ShowWeekNumbers="true">
      <SelectionMode Day="false" Days="false" WeekNumber="false" WeekDay="false" Month="true" />
  </wijmo:C1Calendar>

  Regards,
  
  Uttkarsh.
