  Hi,
  
  Migrate from 2010v1 to 2025v2 399 in ASP.NET WebForms NET Framework 4.8.1.
  
  Using C1GridView from C1.Web.Wijmo.Controls.48.dll

  Changes C1Window to C1Dialog control.
  
  Not working this code (set_x, set_y, set_text… ) with C1Dialog, any alternatives ?

  In my legacy code using C1Window 2012v1, I use C1Window functions:

         var show = function (args) {
          var w = controls.C1Window1;
          //w.set_showModalWindowOnLoad(false);
          
          if (title != '') { w.set_text(title); }
          
          if (width) {
              w.set_width(width);
          }
  
          if (height) {
              w.set_height(height);
          }
          
          w.set_startPosition(1);
          w.set_verticalAlign(1);
          w.set_horizontalAlign(1);
          w.showModal();
          controls.btnAccept.focus();
      };
  	
  	
  	
   dialog.showModal();
  
     dialog.set_x(200);
     dialog.set_y(250);
  
    dialog.get_visible();
  
   dialog.set_text(title);
   dialog.set_startPosition(C1.Web.UI.Controls.C1Window.C1WindowPosition.page);
   dialog.set_verticalAlign(C1.Web.UI.Controls.C1Window.VerticalPosition.middle);
   dialog.set_horizontalAlign(C1.Web.UI.Controls.C1Window.HorizontalPosition.center);
   
  dialog.hide();
  

  which are the new functions ?

  set_showModalWindowOnLoad
  set_text
  set_width
  set_height
  set_startPosition
  set_verticalAlign
  set_horizontalAlign
  showModal
  

  ShowModalWindowOnLoad not exists in C1Dialog:

  Can you help me about those functions, please? Thanks in advanced

  I need the alternative new functions for old functions? :

  set_showModalWindowOnLoad
  
  set_text
  
  set_width
  
  set_height
  
  set_startPosition
  
  set_verticalAlign
  
  set_horizontalAlign
  
  showModal
  
  hide
  
  set_x
  
  set_y
  
  get_visible

  How-to use c1dialog with position for startPosition, verticalAlign, horizontalAlign ?

     // Set value
      var newValue; // Type:  any
      $(".selector").wijdialog("option", "position", newValue);

  I try

  var dialog = $("#" + C1WindowClientID);
  dialog.c1dialog({
  				title: TitleText,
  				modal: true
  });
  dialog.c1dialog({ position: '[200,250]' });
  dialog.c1dialog("open");

  			var dialog = $("#" + clientId);
  			return  dialog.c1dialog("isOpen");

  Align middle + center from VPos + HPos

  dialog.c1dialog({ position: 'center' });

  whats about

     $(".selector").wijdialog("option", "position", newValue);

  Hi,

  Both of the code snippets below are correct, and either one can be used.

  dialog.c1dialog({ position: 'center' });

  $(".selector").wijdialog("option", "position", newValue);

  Regarding the “set_*” JavaScript methods you mentioned above, these are no longer available in the C1Dialog. Therefore, you will need to use either of the above code snippets to set these properties as well.

  c1dialog is valid, in the samples code appears c1dialog
  
  wijdialog is valid too ??

  is the same ?

  dialog.c1dialog({ position: 'center' });

  dialog.wijdialog("option", "position",  'center');

  Hi,

  You can use any of the below

  dialog.c1dialog({ position: 'center' });

  $(".selector").c1dialog("option", "position", newValue);

  The wijdialog is just to showcase the syntax and cannot not be used directly in code
