My graph doesnt appear on my form...

Israel

Hi!

I cannot see appearing my graph on my form.
The first error message I receive is:

The type or namespace name 'UI' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)

The segond is:

The name 'SeriesChartType' does not exist in the current context

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.Data.SqlClient;

using System.Web.UI.DataVisualization.Charting;//The first Error message it's here

namespace WindowsFormsApplication1

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

SqlConnection conn = new SqlConnection("Data Source=localhost\\sqlexpress;Initial Catalog=master;Integrated Security=True");

string qry = "select Name, salary from salary from employee";

SqlDataAdapter da = new SqlDataAdapter(qry, conn);

DataSet ds = new DataSet();

da.Fill(ds,"salary");

chart1.Series["Series1"].XValueMember="name";

chart1.Series["Series2"].YValueMembers="salary";

this.chart1.Titles.Add("employee salary");

chart1.Series["series1"].ChartType = SeriesChartType.Pie;// the Segond error message it's here

chart1.Series["series1"].IsValueShownAsLabel = true;

}

Hey israel this is not a big problem you just check your code once. i think you are missing some thing once you go throw your code. see try and catch block and every ; (semicolon ).

You don't appear to have set the Chart control's DataSource property:

da.Fill(ds,"salary");
chart1.DataSource = ds.Tables[0];
chart1.Series["Series1"].XValueMember="name"
chart1.Series["Series2"].YValueMembers="salary";

Try changing this line:

using System.Web.UI.DataVisualization.Charting;

to this:

using System.Windows.Forms.DataVisualization.Charting;
