  Hi,
  
  Migrate from 2010v1 to 2025v2 399 in ASP.NET WebForms NET Framework 4.8.1.
  
  Using C1Calendar from C1.Web.Wijmo.Controls.48.dll
  
  Changes C1Calendar from 2010v1 to 2025v2 399 control.
  
  Now those properties changes:

  C1Calendar.SelectionMode = C1.Web.UI.Controls.C1Calendar.SelectionMode.Day;

  How-to use C1.Web.Wijmo.Controls.C1Calendar.SelectionSettings.Day now ?

   //Initialice date with current mounth
   C1Calendar.SelectionMode = //C1.Web.Wijmo.Controls.C1Calendar.SelectionSettings.Day; //= C1.Web.UI.Controls.C1Calendar.SelectionMode.Day;
   C1Calendar.SelectedDate = new DateTime(int.Parse(desde.Substring(0, 4)), int.Parse(desde.Substring(5, 2)), int.Parse("01"));

  any suggestion please ?

  Hi,

  In the latest versions of C1Calendar, the SelectionMode property provides separate Boolean properties to enable or disable the supported selection modes. You can configure them as follows:

  'these are enabled by default
  C1Calendar1.SelectionMode.Day = True
  C1Calendar1.SelectionMode.Days = True
  
  'these are disabled by default
  C1Calendar1.SelectionMode.WeekNumber = True
  C1Calendar1.SelectionMode.WeekDay = True
  C1Calendar1.SelectionMode.Month = True

  You can set these properties according to your requirements to enable or disable the corresponding selection modes.

  Best Regards,
  
  Kartik

  In aspx-ascx Markup:

    SelectionMode="Day" 

  latests version:

  SelectionMode-Day="true"
        SelectionMode-Days="false"

  sample:

    <cc1:C1Calendar ID="C1SurveyDateFrom" runat="server" style="font-size: xx-small" 
        Height="180px" Width="230px"
        PopupMode="True"
        WeekDayFormat="Abbreviated"                             
        AllowPreview="false"
        ShowWeekNumbers="false"
        EnableViewState="true"
        SelectionMode-Day="true"
        SelectionMode-Days="false"
        TitleFormat="MMMM 'de' yyyy" 
        MonthViewTitleFormat="MMMM 'de' yyyy">
    </cc1:C1Calendar>

  these are disabled by default, then is FALSE:

  C# sample:

  C1Calendar1.SelectionMode.WeekNumber = false;
  C1Calendar1.SelectionMode.WeekDay = false;
  C1Calendar1.SelectionMode.Month = false;

  and
  
  SelectionMode can be applied using javascript wijmo c1calendar ?

  thanks a lot

  Hello Enrique,

  Regarding the default values for SelectionMode, we have already discussed it on the following thread:

  Regarding setting SelectionMode using JS, please refer to the following option in c1calendar:

  To explore other similar options, please refer to https://help.grapecity.com/wijmo/3/webframe.html#Wijmo~wijmo.calendar.wijcalendar.options.html

  Sample code to set “selectionMode” option using jQuery:

  function selectionMode() {
      var cal = $("#<%=C1Calendar1.ClientID%>");
      
      var selectionModeVal = cal.c1calendar('option', 'selectionMode');
      cal.c1calendar('option', 'selectionMode', {
          day: false,
          days: true,
          month: true
      });
  }
