SharePoint People Picker Control read Users and Groups

            However one of the things I needed to do was to use the control not just pick people but also to pick AD domain groups. This functionality is provided by the control but is not enabled by default when you create a new PeopleEditor class instance. In order to enable it you need to set the SelectionSet string property of the control to a comma separated list of the entities you want your people picker control to pick. Possible values are User for AD User, SecGroup for AD Group, DL for AD distribution list and SPGroup for a SharePoint group.

Delete sharepoint site group using powershall command

$spWeb = Get-SPWeb "http://trig161:1089"
$spGroups = $spWeb.SiteGroups

$groups = ("Group1","Group2","Group3","Group4","Group5")

ForEach($group in $groups) {
   $spGroups.Remove($group)
}

$spWeb.Dispose()

Get Server side data using jq

public partial class handlerPage : IHttpHandler
    {
        bool IHttpHandler.IsReusable
        {
            get
            {
                return false;
            }
        }

        void IHttpHandler.ProcessRequest(HttpContext context)
        {
            // throw new NotImplementedException();
            System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer();
            string ResultString = string.Empty;
            List<CharEntity> Lst = new List<CharEntity>();
            Lst = GetDataFromList();
            ResultString = js.Serialize(Lst);
            context.Response.Write(ResultString);
        }
    }

 public List<CharEntity> GetDataFromList()
        {
            List<CharEntity> Lst = new List<CharEntity>();
                      for (int x = 0; x <= 2; x++)
                        {
                            Lst.Add(new CharEntity
                            {
                                TaskName = Task[x],
                                TaskValues=val[x]
                            });
                        }
}

 function getChart(val) {
        var ChartData = GetChartData();
}

 function GetChartData() {
        try {
            var Task1 = new Array();

            var url = "/_layouts/15/Igrid_Petronash/handlerPage.ashx";
            var xmlHttp = new XMLHttpRequest();
            xmlHttp.open("POST", url, false);
            xmlHttp.send(null);
            var layerHTML = xmlHttp.responseText;
            var msg1 = JSON.parse(layerHTML);
            return msg1;
}}

Pupop window using 

 $("[id$=linkJobTitle]").live("click", function () {

        var ItemValue = $(this).next('input:hidden[id$=hidden]').val();

            alert(e);

        }

WEBPART PAGE LIFECYCLE

          creating webpart contains various life cycle similar like ASP.net page lifecycle. but based on on your environment it will be differ:

OnInit – Configuration values set using WebBrowsable properties and those in web part task pane are loaded into the web part.

LoadViewState – The view state of the web part is populated over here.

CreateChildControls – All the controls specified are created and added to controls collection. When the page is being rendered for the first time the method generally occurs after the OnLoad() event. In case of postback, it is called before the OnLoad() event. We can make use of EnsureChildControls() – It checks to see if the CreateChildControls method has yet been called, and if it has not, calls it.

OnLoad User Generated Event – for e.g. button click on the web part.

OnPreRender – Here we can change any of the web part properties before the control output is drawn.

RenderContents – Html Output is generated.

SaveViewState - View state of the web part is serialized and saved.

Dispose -UnLoad.
