SharePoint 2010 Calendar: Remove Custom Commands tab and Add new export event button in view tab

To achieve this functionality we have to first hide the custom commands tab from event list.

  • Open Visual Studio. 
  • Create SharePoint Empty project.
  • Add UserControl give it name CalendarFeature.
  • Include dll in your project from Path : C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI\Microsoft.Web.CommandUI.dll
  • Write the following lines of codes in ascx file.
protected void Page_Load(object sender, EventArgs e)
            SPRibbon ribbon = SPRibbon.GetCurrent(this.Page);
            if (ribbon != null)
  • Open SharePoint Designer edit calendar DispForm.Aspx(edit in advanced mode.)
  • Add the following lines to register TrimCustomAction.ascx in your page. 
<%@ Register src="/_ControlTemplates/CalendarFeature/TrimCustomAction.ascx" tagname="RemoveCalEvent" tagprefix="Trim" %>
  • Then find "PlaceHolderMain" text from DispForm.aspx page after write the following lines.
  • You can also add the above line in v4.master page.
  <Trim:RemoveCalEvent ID="RemoveCalEvent" runat="server" />
  • You will see now there is no command event available any more.
