  Hi,

  Migrate from 2010v1 to 2025v2 399 in ASP.NET WebForms NET Framework 4.8.1.
  
  Migrating C1Window to C1Dialog 2025v2 399.
  
  Using C1Dialog from C1.Web.Wijmo.Controls.48.dll

  I have the code javasciprt:

  	var dialog = $("#" + C1WindowClientID);
  	dialog.c1dialog({
  		title: TitleText,
  		modal: true
  	});
  	dialog.c1dialog("open");

  I use open and close, now in C1Dialog 2025v2 399.

  Which is the alternative now, for C1Dialog 2025v2 399
  
  Differences using open or show ?
  
  Differences using close or hide ?

  		dialog.show()

  		dialog.hide()

  Thanks a lot

  Hello Enrique,

  show() / hide() only affect the DOM, not the dialog. They do not initialise the dialog, change its internal state or trigger the events.

  To open/show the dialog, use:

  function openDialog() {
      let dlg = $("#<%= C1Dialog1.ClientID %>");
      dlg.c1dialog("open");
  }

  To close/hide the dialog, use:

  function closeDialog() {
      let dlg = $("#<%= C1Dialog1.ClientID %>");
      dlg.c1dialog("close");
  }

  Please refer to the attached sample for implementation. (see Dialog_Sample.zip)

  Regards,
  
  Uttkarsh.
