  Hello Enrique,

  • ClientOnAfterClose=“CalendarClosedDesde”: It seems you are referring to when the Calendar is closed in InputDate. If so, you can use “OnClientDropDownClose” in InputDate.
    
    If this is not your requirement, please let us know sharing more information on this requirement and use case.

  • FirstDayOfWeek=“Monday”: We’re sorry but we did not find a direct replacement for this property.
    
    As per our understanding, you are working with Spanish culture. If so, please set the Culture property to “es-ES” and this will automatically set the first day of the week to Monday.

  • CalendarTitle=“{0:dd} de {1:MMMM} de {2:yyyy}”: You can use “TitleFormat” property setting it as “dd ‘de’ MMMM ‘de’ yyyy”.

  • MonthViewTitle=“{0:MMMM} de {1:yyyy}”: You can use “MonthViewTitleFormat” property setting it as “MMMM ‘de’ yyyy”.

  • Legacy Styling properties: Legacy styling properties are not used anymore, please use CSS based styling instead.

  thanks Uttkarsh!

  About ClientOnAfterClose=“CalendarClosedDesde”

  I have legacy javascript functions:

          function SelectDateDesde() {
              var calendar = Sys.Application.findComponent("<%=C1CalDesde.ClientID%>");
              var input = document.getElementById("Text1");
              calendar.popupBeside(input, C1.Web.UI.PositioningMode.bottomLeft);
          }
  
          function CalendarClosedDesde() {
              var calendar = Sys.Application.findComponent("<%=C1CalDesde.ClientID%>");
              var input = document.getElementById("Text1");
              var month;
              month = calendar.get_selectedDate().getMonth() + 1;
              input.value = calendar.get_selectedDate().getDate() + "/" +
                              month + "/" +
                              calendar.get_selectedDate().getFullYear();
          }

  Please, what is

  calendar.get_selectedDate()

  and

  calendar.popupBeside(input, C1.Web.UI.PositioningMode.bottomLeft);

  ?

  for C1Calendar, what is the properties-events (client):

                          OnClientBeforeSlide
                          OnClientAfterSlide
                          OnClientBeforeSelect
                          OnClientAfterSelect
                          OnClientCustomizeDate
                          OnClientSelectedDatesChanged
  

  Thanks in advanced,!

  Hello Enrique,

  → calendar.get_selectedDate()
  
  Instead of get_selectedDate(), you can use “date” option. [ref: https://help.grapecity.com/wijmo/3/webframe.html#Wijmo~wijmo.input.wijinputdate.options~date.html]

  → calendar.popupBeside(input, C1.Web.UI.PositioningMode.bottomLeft);
  
  There is no direct replacement for this. You can set the pop-up position and then call the “Drop” function on wijinputdate to display calendar using code. [ref: https://help.grapecity.com/wijmo/3/webframe.html#Wijmo~wijmo.input.wijinputdate~drop.html]

  → Calendar client-side events:
  
  Please refer to the documentation for their usage: https://help.grapecity.com/wijmo/3/webframe.html#Wijmo~jQuery.fn.-~wijcalendar.html
