  Hello Enrique,

  • webcalendar=“C1Calendar2”: We have escalated this to the development team to see if there are any alternative for this property. Could you please share the exact use-case of this property? What was its function and how was it set?
    
    [Internal Tracking ID: C1WEB-30340]

  • webcalendarpopupposition=“Below”: You can use the properties starting with “PopupPosition-*” to configure pop-up position.

  • custombuttonalign=“Right”: You can use the “DropDownButtonAlign” property to set the button position.

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

  Thanks at all.

  webcalendar=“C1Calendar2” references the ID of Calendar control.
  
  C1Calendar2 is the ID of my calendar control in my page.

  Please, which is the alternative value for webcalendarpopupposition=“Below” using PopupPosition?

  PopupPosition-At-Left="Right"

  thanks all in advanced

  Hello Enrique,

  Regarding “webcalendar” property, there is a “Calendar” string-type property in new C1InputDate which determines the calendar element for a date input. Could you please confirm if it works for your use-case? If you face any issues, please let us know the details such as expected (previous) behavior and current behavior.

  For “webcalendarpopupposition=“Below””, we’re not exactly sure how you are displaying the calendar at your end, so we suggested relevant properties that can help you display the calendar at intended position.

  For example, if you want to display the calendar at bottom - starting at center, you can use the following combination:

  PopupPosition-At-Left="Center" PopupPosition-At-Top="Bottom"

  This will result in the following:

  Uttkarsh.

  Hello Enrique,

  The team has provided the following update for “C1WEB-30340”:

  After reviewing both the WebForms wrapper and the underlying Wijmo implementation, we would like to clarify the behavior of the Calendar property in C1InputDate (2025v2).

  In the legacy C1DateInput control (2010v1), the WebCalendar property allowed attaching and synchronizing an external WebCalendar/C1Calendar control with the input. This enabled scenarios where a separate calendar control could be injected and shared.

  In contrast, the current Wijmo-based C1InputDate follows a different architectural model:

  • The calendar is internally created and owned by the InputDate control.
  • The underlying Wijmo InputDate exposes a read-only calendar property that returns a reference to this internally managed Calendar instance.
  • There is no setter, and the internal calendar instance cannot be replaced with an external control.
  • Synchronization between the input and the calendar is automatic because the control directly delegates its value to the internally managed calendar instance.

  Therefore:

  • The Calendar property is not provided for API compatibility only. It is functional, but its purpose is to allow configuration of the internal calendar instance (e.g., formatting, header visibility, item formatting, etc.).
  • However, it does not provide equivalent functionality to the legacy WebCalendar property. Replacing the popup calendar with an externally defined calendar control is not supported in the current Wijmo-based implementation.

  Regards,
  
  Uttkarsh.
