Dynamically setting Pie Chart DatapointStyle in Silverlight

         Required Namespaces

      

           using System.Windows.Controls.DataVisualization.Charting;

           using System.Windows.Controls.DataVisualization;

               

         first create a chart using the chart class and create the pie series 

              

            Chart  piechart = new Chart();

            PieSeries   ps  = new PieSeries();

                         

         Then map the pieseries to data,here i have used four records ,so  the pie chart

         will have four slices.                

            List<data> DAT = new List<data>();

            DAT.Add(new data() { project="project1",completed=50 });

            DAT.Add(new data() { project = " project2 ", completed = 100 });

            DAT.Add(new data() { project = " project3 ", completed = 20 });

            DAT.Add(new data() { project = " project4 ", completed = 10 });

             

            ps.IndependentValuePath = "project";

            ps.DependentValuePath  = "completed"; 

            ps.ItemsSource = DAT;

            public class data

                {

                     public string project{get;set;}

                     public int completed{get;set;}

                }

         Now u need to create multiple styles for the pie chart DataPoint,

         each style will be applied to each slice in the pie chart.

         Each  Style must be enclosed in ResourceDictionary class   

            ResourceDictionary rs1 = new ResourceDictionary();

            Style datapointstyle1 = new Style(typeof(DataPoint));

            datapointstyle1.Setters.Add(new Setter(BackgroundProperty, "#FF42B444"));

            datapointstyle1.Setters.Add(new Setter(OpacityProperty,"0.8"));

            rs1.Add("DataPointStyle",datapointstyle1);

            ResourceDictionary rs2 = new ResourceDictionary();

            Style datapointstyle2 = new Style(typeof(DataPoint));

            datapointstyle2.Setters.Add(new Setter(BackgroundProperty, "#FFF73110"));

            datapointstyle2.Setters.Add(new Setter(OpacityProperty, "0.8"));

            rs2.Add("DataPointStyle", datapointstyle2);

            ResourceDictionary rs3 = new ResourceDictionary();

            Style datapointstyle3 = new Style(typeof(DataPoint));

            datapointstyle3.Setters.Add(new Setter(BackgroundProperty, "Blue"));

            datapointstyle3.Setters.Add(new Setter(OpacityProperty, "0.8"));

            rs3.Add("DataPointStyle", datapointstyle3);

            ResourceDictionary rs4 = new ResourceDictionary();

            Style datapointstyle4 = new Style(typeof(DataPoint));

            datapointstyle4.Setters.Add(new Setter(BackgroundProperty, "Gray"));

            datapointstyle4.Setters.Add(new Setter(OpacityProperty, "0.8"));

            rs4.Add("DataPointStyle", datapointstyle4);

         Now we add all the resource dictionaries to a single collection,the

         ResourceDictionaryCollection

            ResourceDictionaryCollection coll = new ResourceDictionaryCollection();

            coll.Add(rs1);

            coll.Add(rs2);

            coll.Add(rs3);

            coll.Add(rs4);

         finally we are going to apply the styles to the piechart

                           

            piechart.Pallete = coll;

            

         Now add the Pie Series to the PieChart

             piechart.Series.Add(ps); 

            

Changing ADS User Password Programatically

   First you need to include the reference

            using  System.DirectoryServices;

   then create an object  for the DirectoryEntry Class

        DirectoryEntry de = new DirectoryEntry ();

   Now set  the properties for the DirectoryEntry Object,you  need

   to provide administrative previleges such as UserName and Password.

        de.Path     =    ldap://dc=Name,dc=net/;

        de.Username =   "admin";

        de.Password =   "12345";

        de.AuthenticationType = AuthenticationTypes.Secure;

   Now using a directory searcher we will retrive all the users in the ADS
   the result from directory searcher is placed in a searchresultcollection.

        DirectorySearcher desearch = new DirectorySearcher(de);　

        desearch.SearchRoot = de;
        SearchResultCollection result;

        result = desearch.FindAll();

   From the SearchResultCollection,using for loop we find the appropriate user 

   that we  want to change the  password for, then we invoke  the setpassword 

   method of the particular Directory  Entry to change the password.

  

        foreach (SearchResult s in result)
         {
            DirectoryEntry d = s.GetDirectoryEntry();

            d.Username = "admin";
            d.Password = "12345";

            d.AuthenticationType = AuthenticationTypes.Secure;

            if (d.Properties["Name"].Value.ToString() == "username")
             {

                d.Invoke("SetPassword", new object[] { pass });
                d.CommitChanges();

             }

           }
