Hi Chris
Sorry to hear about the inconvenience. Can he try using the 3.3.0.0 version of Essential Studio as we have made changes to make it easier to use and deploy the ASP.NET controls.
If he still wants to use Essential Studio 3.2.1.0:
a) Is he using VS.NET 2003? Version 3.201.1.0 assemblies should be used with VS.NET 2003 and here are all the assemblies he should be using:
<%@ Register TagPrefix="cc4" Namespace="Syncfusion.Grouping" Assembly="Syncfusion.Grouping.Base, Version=3.201.1.0, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" %>
<%@ Register TagPrefix="cc3" Namespace="Syncfusion.Windows.Forms.Grid" Assembly="Syncfusion.Grid.Windows, Version=3.201.1.0, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" %>
<%@ Register TagPrefix="cc2" Namespace="Syncfusion.Styles" Assembly="Syncfusion.Shared.Base, Version=3.201.1.0, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" %>
<%@ Register TagPrefix="ssw" Namespace="Syncfusion.Web.UI.WebControls.Tools" Assembly="Syncfusion.Shared.Web, Version=3.201.1.0, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" %>
<%@ Register TagPrefix="sfwg" Namespace="Syncfusion.Web.UI.WebControls.Grid.Grouping" Assembly="Syncfusion.Grid.Grouping.Web, Version=3.201.1.0, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" %>
b) Also, does he have the LicenseContext.slf in the bin (output) folder? This file is generated during install and is located in the InstallRoot\Templates folder. He should this file to the output directory of your application. Note: You can also use the GenerateSLF.exe utility located in the InstallRoot \Utilities\GenerateSLF folder to generate the LicenseContext.slf file.
c) The scripts and images used by the control are under /Syncfusion/Resources/GroupingGridWeb directory. The ImageFilesPath and ScriptFilesPath property of the GridGroupingControl point to this directory.
Can you ask him to check these out. It would be a better idea to try out the 3.3 version which he can download
here.
Regards
Arun
