  Hi,

  Migrate from 2010v1 to 2025v2 399 in ASP.NET WebForms NET Framework 4.8.1.

  Using C1Dialog from C1.Web.Wijmo.Controls.48.dll

  I was used those properties:

  VisualStylePath="~/VisualStyles"
  UseEmbeddedVisualStyles="False"
  VisualStyle="CustomVisualStyle2"
  StartPosition="Page"
  VerticalAlign="Middle"
  HorizontalAlign="Center"
  AllowResize="false" 
  OnClientShown="C1Window1_OnClientShown" 

  By example, OnClientShown not exists now in C1Dialog 2025v2 399.

  Which is the alternative now, for C1Dialog 2025v2 399

  And for the other properties ?

  Thanks a lot

  Hello Enrique,

  • The legacy styling properties such as VisualStylePath, UseEmbeddedVisualStyles and VisualStyle are no longer present or used. Now, you have to use CSS to style your control. Please refer to https://developer.mescius.com/componentone/docs/webforms/online-dialog/dialogforaspnetwijmo2.html for more information.

  • To specify the dialog position, please refer to Position property: https://developer.mescius.com/componentone/docs/webforms/online-dialog/C1.Web.Wijmo.Controls.45~C1.Web.Wijmo.Controls.C1Dialog.C1Dialog~Position.html

  • AllowResize is renamed to Resizable

  • OnClientShown is renamed to OnClientOpen

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

  Regards,
  
  Uttkarsh.

  please, can you put sample about it ?

  this.C1Window1.AllowMove = false;
  this.C1Window1.X = 120;
  this.C1Window1.Y = 280;
  this.C1Window1.StartPosition = C1.Web.UI.Controls.C1Window.C1WindowPosition.Manual;

  How-to put AllowMove now in C1Dialog ?
  
  How-to put StartPosition = Manual now in C1Dialog ?
  
  How-to use X and Y now in C1Dialog , x = 120 and y = 280 ? Position=“[120,280]”

  Position Property (C1Dialog)
  
  Specifies where the dialog should be displayed. Possible values: 1) a single string representing position within viewport: ‘center’, ‘left’, ‘right’, ‘top’, ‘bottom’. 2) a string with array format containing an x,y coordinate pair in pixel offset from left, top corner of viewport (e.g. “[350,100]”) 3) a string with array format containing x,y position string values (e.g. “[‘right’,‘top’]” for top right corner).

  Position="['right','top']"

  but which X and Y values ?

  Can you help me please ?

  Hello Enrique,

  1. AllowMove is renamed to Draggable.
  2. Position=“[120,280]” is correct.

  Please refer to the attached modified sample for the same. (see Dialog_Sample_Mod.zip)
