  Which is the latest version for ASP.NET WebForms ?

  Now, I test trial for ASP.NET WebForms 2025v2 (build 399)

  C1.Web.Wijmo.Controls.48, Version=4.8.20252.399, Culture=neutral, PublicKeyToken=9b75583953471eea

  For your support samples using build 403 ??

  licenses.licx
  
  C1.Web.Wijmo.Controls.C1GridView.C1GridView, C1.Web.Wijmo.Controls.48, Version=4.8.20252.403, Culture=neutral, PublicKeyToken=9b75583953471eea
  
  C1.Web.Wijmo.Controls.C1GridView.C1GridView, C1.Web.Wijmo.Controls.48, Version=4.8.20252.399, Culture=neutral, PublicKeyToken=9b75583953471eea

  I try your samples, and I get

  1>C:\temp\GridView_Sample_Mod.zip__DataFormat\GridView_Pagination\Properties\licenses.licx(2): error LC0004: Exception occurred creating type ‘C1.Web.Wijmo.Controls.C1GridView.C1GridView, C1.Web.Wijmo.Controls.48, Version=4.8.20252.399, Culture=neutral, PublicKeyToken=9b75583953471eea’ System.ComponentModel.LicenseException: No se puede conceder una licencia válida para el tipo C1.Web.Wijmo.Controls.C1GridView.C1GridView. Póngase en contacto con el fabricante del componente para más información.

  I have deleted the line
  
  C1.Web.Wijmo.Controls.C1GridView.C1GridView, C1.Web.Wijmo.Controls.48, Version=4.8.20252.399, Culture=neutral, PublicKeyToken=9b75583953471eea

  and its works.

  4.8.20252.403 is latest version ?

  C1.Web.Wijmo.Controls.48, Version=4.8.20252.403, Culture=neutral, PublicKeyToken=9b75583953471eea

  Hi,

  Yes, the latest version of the C1 WebForms controls is 4.8.20252.403. You can install this version using the ComponentOneControlPanel installer by navigating to the “Web” tab. Please see the attached screenshot for reference - C1ControlPanel.zip

  Regarding the project licensing - To license a WebForms project that uses C1 WebForms controls, you need to embed either a licenses.licx file or a .gclicx file in the project. If the licenses.licx file contains valid entries (like the example below), you should be able to use the C1GridView control without any issues.

  C1.Web.Wijmo.Controls.C1GridView.C1GridView, C1.Web.Wijmo.Controls.48

  Note: The Version, Culture, and PublicKeyToken attributes are not mandatory in the entries.

  Best Regards,
  
  Kartik

  Hi,

  Yes, your new license purchased for the 2025v2 release will allow you to upgrade to the 2025v2.1(403) release as well.
