Some helpful CRM 2016 Bookmarklets

I’ve been working in CRM Online (2016) a little for the past few weeks and I found these little bookmarklets to be helpful.

For those that don’t know, a bookmarklet is a snippet of JavaScript that can be saved as a Bookmark in Chrome, IE or Firefox. By prefixing your JavaScript function with javascript: you’re telling the browser to execute JavaScript rather than go to a particular URL

So far I have bookmarklets to

  • Print the current entity’s schema name
  • Print the current entity’s ID
  • Reopen the current entity’s form

The Print ones are quite nice because I used CRM’s in-built notification system.

window.showModalDialog() deprecated in Chrome

Came across this today:

As of Chrome 37, this feature has now been deprecated. This caught me out with some old legacy code, so I thought I’d share

Using SharePoint REST to create a folder

I was tasked with creating some folders in a Picture Library and I thought that this would be the perfect opportunity to use the SharePoint 2013 REST API for the first time.
It was actually quite easy:

function CreateFolder (){
    var url_web;
    var pictureLibrary
    var folder_name;
    var folder_path;

    url_web = _spPageContextInfo.webAbsoluteUrl;
    pictureLibrary = 'Pictures';
    folder_name = 'jasonscript';
    folder_path = pictureLibrary + '/' + folder_name;

        'url' : url_web + "/_api/Web/Folders/Add('"+ folder_path + "')",
        'type' : 'POST',
        'headers' : { 
            'accept' : 'application/json; odata=verbose', 
            'content-type' : 'application/json; odata=verbose',
            'X-RequestDigest' : $('#__REQUESTDIGEST').val()
        'success' : function (evt){
            // folder has been created
        'error' : function (jqXHR, textStatus, errorThrown){
            // handle the error

The biggest problem that I had was that I found that the Add method seems to only accept values wrapped in single quotes.
I typically use single quotes to define my strings

    var myString = 'wrapped in single quotes';

However, when I tried this

    url_web + '/_api/Web/Folders/Add("'+ folder_path + '")'

I kept getting ‘bad request’ errors. Switching the quotes around resolved this problem.

    url_web + "/_api/Web/Folders/Add('"+ folder_path + "')"

JSON and the JavaScriptSerializer

Today I was trying to write a web service method that would allow me to run some stored procedures on my table. Rather than having multiple web service calls for each stored procedure I wanted to come up with some generic functions that could call a range of stored procedures:

  1. Scalar
  2. NonQuery
  3. Retrieve DataTable

Each of these stored procedures require a Stored Procedure name and a collection of SQL Parameters. I decided to instead take a JSON string which would be easy to create from the client and easy to parse on the server.

Here’s the JSON snippet that I came up with

    "procName" : "sp_updateUser",
    "procVars" : 
              "paramName" : "firstname",
              "paramValue" : "jasonscript",
              "paramDirection": "Input"
              "paramName" : "planet",
              "paramValue" : "Earth",
              "paramDirection": "Input"

Pretty simple. Then in my web service I created two classes:

  1. for my container
    internal class Proc
        public string procName;
        public List<ProcArg> procVars;
        public Proc()
            this.procName = "";
            this.procVars = new List<ProcArg>();
  2. for my parameters:
    internal class ProcArg
        public string paramName
        public string paramValue
        public string paramType;
        public ProcArg()
            this.paramName = "";
            this.paramValue = "";
            this.paramType = "";

Next step was to parse the JSON string to these classes

var jsSerializer = new JavaScriptSerializer();
var spInfo = jsSerializer.Deserialize<Proc>(json);

Now I can access everything from my JSON string in my spInfo object

spInfo.procName               == "sp_updateUser"
spInfo.procVars.Count         == 2
spInfo.procVars[0].paramName  == "jasonscript"
spInfo.procVars[1].paramValue == "Earth"

The JavaScriptSerializer will attempt to match the keys of the JSON string to the public properties of each Class.

JSON.procName                 == Proc.procName

These mappings can be altered using DataMember attributes. For example, I could re-write the Proc class as follows:

internal class Proc
    [DataMember(Name = "procName")]      // specify the name to use for serializing
    public string spName;                // renamed so no longer matches JSON snippet
    public List<ProcArg> procVars;

    public Proc()
        this.spName = "";
        this.procVars = new List<ProcArg>();

Thanks to the DataMember property, the JavaScriptSerializer can still map the JSON string to the class property

Javascript and Working with the SharePoint 2013 People Picker

The People Picker in SharePoint 2013 has had a bit of a face-lift.

The ‘Verify Address’ and ‘Address Book’ icons are gone and what’s left is a cleaner, simpler interface.

But new controls means that some of the older approaches to working with the People Picker no longer work.

As usual I’m working with SharePoint 2013 on the client side (CSOM) working with JavaScript and jQuery.

Here are some of the results that I’ve found

SharePoint Dialog Page – Opening a Custom Page

Recently I learned something new while working with SharePoint 2010.

I was working with a SP List’s NewForm page and was restricted to working on the client-side only (i.e. No server side code / web parts).

The basic scenario was that I had a List of Issues. Each individual Issue could then have related Issues.
So our List basically looked like:

  • Issue ID
  • Issue Name
  • Related Issues (IDs)

The customer didn’t like the default lookup controls to select the Related Issues because they could have a LOT of Issues in the system at any one time (600+ Issues) and the default controls don’t really allow the user to filter, sort or do any other wonderful SharePoint things that we can normally do on a List.

The solution that we came up with was to utilise JavaScript and try to improve the UI a little.
