I recently had to figure out how to make the detail view in the SalesLogix 7.5.4 web client refresh after running a common task. The common tasks server side code executed within the LinkHandler.cs file in the App_Code directory. This is how to accomplish that.
Sage.Platform.Application.UI.Web.ApplicationPage s = this.Page as Sage.Platform.Application.UI.Web.ApplicationPage;
if (s.PageWorkItem != null)
Sage.Platform.WebPortal.Services.IPanelRefreshService refresher = s.PageWorkItem.Services.Get<Sage.Platform.WebPortal.Services.IPanelRefreshService>();
if (refresher != null)
