Bamboo Calendar for SharePoint: a problem with permissions...

Today I have worked with Bamboo Calendar for SharePoint.

It is nice, its main features are:

  • possibility to merge 2 or more calendars
  • possibility to give colors based on metadata

It has two main drawbacks:

  • it is slow; not slow, it is really very slow;
  • it is not consistent with permission in the SharePoint object model.


About the last point, I explain here: I have an Intranet site where public visitors don't have read access on the site, but only on some lists and/or folders and of course pages.

If I use the OOTB calendar, everything works fine. But with Bamboo Calendar, I need to give read access to the site and read access to the list, even if I want to get data from a folder only.

This is terrible, because it changes all the permission model I had prepared (and that was fitting the reality very well, while now I had to break inheritance in almost all the lists, to protect them) and is less secure because new content will have, by default, public access.

Btw I tought it could be a problem of asynchronous calls (maybe AJAX call when changing month) but nope.


My final evaluation is: not so good, and I would avoid using it, unless explicitly requested by the client (as in this case).

SharePoint: iid attribute of a List View web part

SharePoint renders list view web parts giving an attribute iid for each tr in the resulting table.

The structure of this iis is: contextID,itemID,objectType.

I understood alone the itemID, I was not sure about the contextID (even if I've understood that it was the same for all the rows, so useless) and I was not sure about the objectType, if it was instead the versionID.

Anyway the blog post The magical IID attribute in SharePoint List Views has helped me, together with the jQuery selector to retrieve the itemID:

var id = $(“tr.s4-itm-selected”).attr(“iid”).split(“,”)[1];

SharePoint: comments with history

In SharePoint OOTB it is possible, for multi-line text fields (like typically comments and notes) to enable versioning of changes of the field only (without the need to go to the version history of the item).

For this, it is necessary, first of all, to enable versioning in the list itself (from List Settings, Versioning Settings, Item Version History, Yes).

Then, in the multi-line text field, in the Additional Column Settings, set Append Changes to Existing Text to Yes.


SharePoint: access denied to the root site even if granted access to the default page

Today I had a problem: even if visitors had access to the site home page, when pointing to the site url directly, they got an Access Denied error, instead of being redirected to the home page.

I have done some research on Internet and it seems that enabling anonymous authentication at the web application level, and then removing it, is able to fix the problem (!).


Here some links I have found:
