  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

  Now, this not compiles:

  C1WindowAdd.ShowModalWindowOnLoad = true;
  C1WindowAdd.StartPosition = C1.Web.UI.Controls.C1Window.C1WindowPosition.Page;
  C1WindowAdd.HorizontalAlign = C1.Web.UI.Controls.C1Window.HorizontalPosition.Center;
  C1WindowAdd.VerticalAlign = C1.Web.UI.Controls.C1Window.VerticalPosition.Middle;

  I use

  C1WindowAdd.ShowOnLoad = true;

  Which is the alternative now, for C1Dialog 2025v2 399 for
  
  StartPosition , HorizontalAlign , VerticalAlign ?

  thanks a lot in advanced, regards

  Hi,

  Thank you for sharing all the details.

  You can use the Position property of the C1Dialog to replace the StartPosition, HorizontalAlign, and VerticalAlign properties. Please see the documentation below for reference.

  Position Property (C1Dialog)

  	//     Center of the page.
  	C1WindowPosition: Page = 1,
  	//     Middle region
  	VerticalPosition: Middle = 1,
  	//     Center rgion
  	HorizontalPosition: Center = 1,
  

  C1WindowAdd.ShowModalWindowOnLoad = true;
  C1WindowAdd.StartPosition = C1.Web.UI.Controls.C1Window.C1WindowPosition.Page;
  C1WindowAdd.HorizontalAlign = C1.Web.UI.Controls.C1Window.HorizontalPosition.Center;
  C1WindowAdd.VerticalAlign = C1.Web.UI.Controls.C1Window.VerticalPosition.Middle;
  C1WindowAdd.Text = (string)_textsShown[14];

  I dont know if this will be the new code??

  C1WindowAdd.ShowOnLoad = true;
  C1WindowAdd.Title = (string)_textsShown[14];
  // TODO
  // C1WindowAdd.Position = "center";
  // or
  // C1WindowAdd.Position = "[\"center\",\"center\"]"; ?????????????????????
  

  Please, any help ? thx a lot!!

  Hi,

  Based on your previous code, it appears that C1Window was aligned at the center of the page. To achieve the same behavior with C1Dialog, you can simply set its Position property to center.

  C1Dialog1.Position = "center";
