Removing “Edit Item” from calendar ribbon in sharepoint 2010

Question

I am facing trouble removing the "Edit Item" ribbon button from calendar DispForm.aspx.

I have created a visual studio 2010 user control where i used the method TrimById("Ribbon.ListForm.Display.Manage.EditItem"); and deployed the solution.

Next I went into calendar's master page and used the control created in the Register tag. If it worked the "Edit Item" in DispForm.aspx should not appear, but it does. Please tell me if I did miss any steps.

SharePoint provides ability to remove ribbon elements using custom actions. This method was tested and I think it is more preferrable and much more flexible, than inserting your custom controls into your masterpage. At least, because custom actions approach is available for sandboxed solutions.

In your case, you probably should use following code to define such custom action:

  <CustomAction
   Id="RemoveEditItemButtonFromCalendar"
   Location="CommandUI.Ribbon.DisplayForm"
   RegistrationType="List"
   RegistrationId="106"
    >
    <CommandUIExtension>
      <CommandUIDefinitions>
        <CommandUIDefinition Location="Ribbon.ListForm.Display.Manage.EditItem" />
      </CommandUIDefinitions>
    </CommandUIExtension>
  </CustomAction>

106 here is the ID of Events list template. If you have your custom list template or standard template other than Events, you should use it instead of 106 value.

If you want to attach your ribbon customizations to a single list, rather than to a list template, you can use SPList.UserCustomActions collection. In your feature receiver you should place following code:

public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
    // considering your feature is web-scoped
    var web = properties.Feature.Parent as SPWeb;

    // fetch SPList object, it must have been created before using this code
    var list = web.GetListFromUrl("path/to/list/AllItems.aspx");

    // create new customAction
    var customAction = list.UserCustomActions.Add();

    // this is for cleanup purposes in FeatureDeactivating
    customAction.Name = properties.Feature.DefinitionId.ToString("N") + "_ribbon";

    // setting custom action location, and the CommandUIExtension element
    customAction.Location = "CommandUI.Ribbon.DisplayForm";
    customAction.CommandUIExtension = @"
      <CommandUIExtension>
        <CommandUIDefinitions>
          <CommandUIDefinition Location=""Ribbon.ListForm.Display.Manage.EditItem"" />
        </CommandUIDefinitions>
      </CommandUIExtension>"

    // saving the changes to database
    customAction.Update();
    list.Update();
}

public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
{
    // cleanup code

    SPWeb web = properties.Feature.Parent as SPWeb;
    var list = web.GetListFromUrl("path/to/list/AllItems.aspx");

    bool collectionChanged = false;
    for (int i = list.UserCustomActions.Count - 1; i >= 0; i--)
    {
        var customAction = list.UserCustomActions.ElementAt(i);

        if (customAction.Name.StartsWith(properties.Feature.DefinitionId.ToString("N")))
        {
            customAction.Delete();
            collectionChanged = true;
        }
    }

    if (collectionChanged)
        list.Update();
}
