       $(":input").each(function () {                                   
   	var _sInputValue = $(this).val();                                        
   	if (_sInputValue==="Save and Close") $(this).hide();
       });
   });
   </script>
   



8. Go to you NewForm.aspx on the designer, right click and “Check Out” and then “Check In”


9. Do the same with EditForm.aspx

HMTL 5, CSS3 and JavaScript for Windows 8 – Little JavaScript tips

In this post I am going to add these small things I always forget when I work with JavaScript and are quite useful:

1. How do you put a message in the browser’s status bar?: windows.status(“hello world”);
2. What do you use to comment in JavaScript?: // and /* */
3. What is the correct way to write a JavaScript array?: var txt = new Array (“Hello”,”World”, “how”);
4. How do you write something with JavaScript?: document.write(“Hello World”);
5. How does a “while” loop start?: while(i<=10);
6. What is the purpose of DOM (Document Object Model)?: The DOM represents the structure of a web page. You use it to add dynamic functionality to the page.
7. DOM core methods to create new objects for a document:
   • document.createElement(tagname)
   • document.createTextNode(string)
   • document.createAttribute(name,value)
   • document.createDocumentFragment
8. How do you round a number to the nearest integer?: Math.round(7.25);
9. How do you find the Maximum number between two numbers?: Math.max(x,y);
10. How to pass a JavaScript reference into a website: <script type=”text/javascript” src=”alertme.js”></script>
11. Internet Explorer 6,7 and 8 do not support addEventListener() and removeEventListener(). Use similar attachEvent() and detachEvent() functions instead.
    Some events in the HTML DOM ‘bubble’ meaning that if the event occurs on an element (and it is or isn’t handled), the event will then also fire on the element’s parent node and then on its grandparent node and so on until the event reaches an element where it may not bubble any further or it reaches the root node. Both addEventListener and removeEventListener have an optional third Boolean parameter indicating whether or not this is the case.
12. How do you find clients browser name?: navigator.appName
13. How do you open a new window in JavaScript?:mywindow=window.open(“http://www.google.com”);
14. How do you split a large string in two lines in Javascript?:
    document.write(“hello my name is \
    prince”);
15. Microsoft implementation of JavaScript is called JScript.
16. <noscript> tag Alerts the users that your page uses JavaScript, and so the user should enable JavaScript in the browser in order to display your page correctly.
17. Having the following code what does this code returns….(this is a nice exercise):

<script>
var a=””
var b=0;
var c=false;
document.write(a==c);//true
document.write(a===c);//false
document.write(b==c);//true
document.write(b===c);//false
</script>

</script>

HMTL 5, CSS3 and JavaScript for Windows 8 – An unofficial collaboration of Web browser manufacturers and interested parties

WHATWG has become a large community where vendors and users have become key in the project. The Web Hypertext Application Technology Working Group (WHATWG) is a community of people interested in evolving HTML and related technologies. The WHATWG was founded by individuals from Apple, the Mozilla Foundation and Opera Software in 2004.

Since then, the editor of the WHATWG specifications, Ian Hickson, has moved to Google. Chris Wilson of Microsoft was invited but did not join, citing the lack of a patent policy to ensure all specifications can be implemented on a royalty-free basis.

The DOCTYPE declaration for this new standard is:

Embedding Google charts into Sharepoint Web Parts

The other day I was developing a portal and at some point the “client” asked to provide a simple pie chart in the landing page. I said to him; “that should be ok”. At that point I was thinking obviously in the lovely Chart Web Part that comes from default in Sharepoint 2010. After talking with him for a while I realised that requirements where quite high, in terms of data collection. I want to clarify I am trying to avoid PerformancePoint Services because I don’t want to activate the service just for one chart.

Obviously I always have plan A,B,C,D…well sometimes I reach Z. I tried to play around a little bit with the Out Of The Box web part, unfortunately plan A was not good enough, I was looking for something sharp, something elegant, something independent from the whole system, and going for plan A should require to create few extra workflows.

Then I tried to create a Visual Webpart, thinking that the System.Web.UI chart control will work properly in Sharepoint 2010. Unfortunately, it didn’t. Big mistake in my side, I was playing with a .NET 4.0 control, obviously Sharepoint 2010 only support .NET 3.5, so I had to abort plan B.

I asked Trev, one of the web developers, and he suggested me Google Charts. In fact he said that they look much better than the .NET ones, because they use AJAX. I went to the Google Chart Tools website and I was amazed about what I saw. Google provides all the information about the API + all the code required, so with a copy paste you can get a nice example in five minutes.

What I did was to create a nice method where you can pass the parameters , build the JavaScript code and embedded into the Web Part. You can use, either a Web Part or a Visual Web Part. In my case I decided to use a Visual Web Part. There is not a particular reason for that.

I am going to do a Step by Step, so you know how to implement it. The result will be a simple pie chart (remember you can create something similar with another Google chart). I will post the project at the end of the article so you can implement it.

- Step 1
Go to Visual Studio 2010->New Project->Sharepoint->2010->Empty Project->call it CPDPointsWebPart and click OK. Select you want to deploy in your farm.

- Step 2
Go to the project, Right click and add->new item…->Sharepoint->2010->Visual Webpart and call it CPDWebPart.

- Step 3
Go to the Feature (Feature1)-> Right click and rename it to CPDWebPartFeature. Your solution should look like this now:

- Step 4
Go to CPDWebPartUserControl.ascx.cs, remove all the code and paste this one:

using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Collections.Generic;
namespace CPDPointsWebPart.CPDWebPart
{
    public partial class CPDWebPartUserControl : UserControl
    {       
        protected void Page_Load(object sender, EventArgs e)
        {
            
            Dictionary<string, int> _dValues = new Dictionary<string, int>();
            _dValues.Add("CPD Training done", 4);
            _dValues.Add("CPD Training Left to be done", 6);
            
            List<string> _lColumns = new List<string>();
            _lColumns.Add("CPD");
            _lColumns.Add("Hours");
            
            Page.RegisterClientScriptBlock("PieChart", GooglePieChart("CPD Points",_dValues,_lColumns,450,300));
        }        
        public string GooglePieChart(string _sTitle, Dictionary<string, int> _dChartParameters, List<string> _lColumns, int _iWidth, int _iHeight)
        {
            System.Text.StringBuilder _Chart = new System.Text.StringBuilder();
            _Chart.Append(@"<script type='text/javascript' src='https://www.google.com/jsapi'></script>");
            _Chart.Append(@"<script type='text/javascript'> ");
            _Chart.Append(@"google.load('visualization', '1', {packages:['corechart']}); ");
            _Chart.Append(@"google.setOnLoadCallback(drawChart);");
            _Chart.Append(@"function drawChart() {  ");
            _Chart.Append(@"var data = new google.visualization.DataTable();  ");
            _Chart.Append(@"data.addColumn('string', '" + _lColumns[0] + "');");
            _Chart.Append(@"data.addColumn('number', '" + _lColumns[1] + "');");
            _Chart.Append(@"data.addRows(" + _dChartParameters.Count.ToString()+ ");");
    
            int i=0;
            foreach (var item in _dChartParameters)
         {
          _Chart.Append(@"data.setValue("+i.ToString()+", 0, '"+item.Key+"'); ");
                _Chart.Append(@"data.setValue(" + i.ToString() + ", 1, " + item.Value+ "); ");   
                i++;
         }
            _Chart.Append(@"var chart = new google.visualization.PieChart(document.getElementById('chart_div'));");
            _Chart.Append(@"chart.draw(data, {width: " + _iWidth.ToString() + ", height: " + _iHeight.ToString() + ", title: '" + _sTitle + "'}); ");
            _Chart.Append(@"}");
            _Chart.Append(@"</script>");
            return _Chart.ToString();
        }
    }             
}

Notice I use Page.RegisterClientScriptBlock(…) to post the JavaScript code into the Visual Web Part.

- Step 5
Double click on CPDWebPartUserControl.ascx and copy and paste this code. The only line I am going to add is “<div id="chart_div"></div> “ . You can add this line from your code as well, but I think by doing it like this we can see the interaction between the JavaScript code and the ascx code.

- Step 6
Deploy the Visual Web Part, go to your site edit the page, insert the webpart (it will be under custom). This should be the result:

Conclusion: Google can provide a very good solution for your charts. There are more chart engines out there you can use, but I find Google the fastest one in terms of performance.

RESTful, Sharepoint Web Services , JavaScript(SP.js) and ASP.NET all together in a Sharepoint 2010 application form

If you see one of my previous post (http://netsourcecode.blogspot.com/2011/09/using-javascript-spjs-in-web-parts-in.html) you will notice I play around with an ASP.NET Application page and one web part from Sharepoint 2010 to display the current user in a message box. I also query a list with another button. I do all of this with JavaScript(SP.js)

The fact is that Andy, my work mate, came on Friday with the idea of detecting a user, query it by getting the properties of the USER PROFILE in a modal form. Good challenge isn’t it?, he is a good man so I always I accept his challenges. I start studying the documentation for the SP.js library and after hours trying to find the way to access to custom user properties I couldn't find anything. You can only get the name, email etc… basic stuff but if you want something else, forget it.

Andy was looking for two fields he created:
       - Department
       - Title

My limitation was extreme, I didn’t have access to the Sharepoint.Client.dll, JavaScript or the Server Model, so I decided to implement the Sharepoint Web Services against JavaScript and use both platforms JavaScript (SP.js) and Web Services (/_vti_bin/UserProfileService.asmx with the method GetUserPropertyByAccountName()).

I have to admit it was hard work, but at the end I managed to make it work.

In the code I am going to post are three buttons which call 3 functions:

• SayHello(): It says hello.
• DisplauUser(): It displays the current user.
• DisplayList(): Displays the “remaining seats”(custom metadata field) of the Shared Documents list.

What do we need to make this work?

1. Visual Studio 2010.
2. Sharepoint 2010.
3. A list called “Shared Documents” with an extra field called remaining seats.
4. Two extra fields in the user profile (Department, Title).
5. Change the references in the JavaScript to the URLs
6. And good luck…

You need to create an application page to run this thing. You can download the project I create in http://netsourcecode.blogspot.com/2011/09/using-javascript-spjs-in-web-parts-in.html and paste the code in the form, if you don’t want to work.
