Export RadChart to pdf for winforms

How do I export radchart to pdf for winforms?

Hi Nicky,

RadChart for WinForms does not support exporting to PDF. However you can save the chart into an image:

radChart1.Save("chart.png", ImageFormat.Png);

and then add your image to whatever document you want.

All the best,

Hello Nicky,
 
Simply try calling the DataBind() method.
Below is a sample code demonstrating the approach:

public partial class Form1 : Form
    {
        private DataTable table;

        public Form1()
        {
            InitializeComponent();

            table = GetTable();

            ChartSeries series = new ChartSeries();
            series.Type = ChartSeriesType.Pie;
            series.DataYColumn = "Value";
            series.Name = "1st Series Name";
            //series.DataLabelsColumn = "Title";
            series.Appearance.LegendDisplayMode = ChartSeriesLegendDisplayMode.ItemLabels;

            radChart1.AutoLayout = true;

            radChart1.Series.Add(series);
            radChart1.Legend.Appearance.Visible = false;
            radChart1.DataSource = table;
            radChart1.DataBind();
        }

        public static DataTable GetTable()
        {
            DataTable table = new DataTable();
            table.Columns.Add("Value", typeof(int));
            table.Columns.Add("Title", typeof(string));

            table.Rows.Add(65, "Text1");
            table.Rows.Add(20, "Text2");
            table.Rows.Add(5, "Text3");
            table.Rows.Add(10, "Text4");
            table.Rows.Add(15, "Text5");

            return table;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            int value = (int)this.table.Rows[0][0];
            value += 100;
            this.table.Rows[0][0] = value;

            this.radChart1.DataBind();
        }
    }

Hope this helps.

Kind regards,
