My Code Like as Bellow
private void LoadChart(GraphOutput resGraph)
{
DataSet_Obj.Tables.Add("CandleTable");
DataSet_Obj.Tables["CandleTable"].Columns.Add(new DataColumn("Date", System.Type.GetType("System.DateTime")));
DataSet_Obj.Tables["CandleTable"].Columns.Add(new DataColumn("Open", System.Type.GetType("System.Double")));
DataSet_Obj.Tables["CandleTable"].Columns.Add(new DataColumn("Close", System.Type.GetType("System.Double")));
DataSet_Obj.Tables["CandleTable"].Columns.Add(new DataColumn("High", System.Type.GetType("System.Double")));
DataSet_Obj.Tables["CandleTable"].Columns.Add(new DataColumn("Low", System.Type.GetType("System.Double")));
for (int i = 0; i < resGraph.graphSymbol[0].CandleSticks.Length; i++)
{
DataRow_Obj = DataSet_Obj.Tables["CandleTable"].NewRow();
DataRow_Obj["Date"] = resGraph.graphSymbol[0].CandleSticks[i].CandleTime; //DateTime
DataRow_Obj["Low"] = resGraph.graphSymbol[0].CandleSticks[i].CandleData.Low; //Float
DataRow_Obj["Close"] = resGraph.graphSymbol[0].CandleSticks[i].CandleData.Close; //Float
DataRow_Obj["Open"] = resGraph.graphSymbol[0].CandleSticks[i].CandleData.Open; //Float
DataRow_Obj["High"] = resGraph.graphSymbol[0].CandleSticks[i].CandleData.High; //Float
DataSet_Obj.Tables["CandleTable"].Rows.Add(DataRow_Obj);
DataRow_Obj = null;
}
Tag_Serie_Candle = new Steema.TeeChart.Styles.Candle ();
chart.Series.Add(Tag_Serie_Candle);
chart.Aspect.View3D = Needs3D(chart[0]);
chart.Panel.Transparent = true;
try
{
Tag_Serie_Candle.DataSource = DataSet_Obj.Tables["CandleTable"]; /* here I got Error Like: "Cannot bind to non-supported datasource: CandleTable" */
Tag_Serie_Candle.OpenValues.DataMember = DataSet_Obj.Tables["CandleTable"].Columns["Open"].ToString();
Tag_Serie_Candle.CloseValues.DataMember = DataSet_Obj.Tables["CandleTable"].Columns["Close"].ToString();
Tag_Serie_Candle.DateValues.DataMember = DataSet_Obj.Tables["CandleTable"].Columns["Date"].ToString();
Tag_Serie_Candle.DateValues.DateTime = true;
Tag_Serie_Candle.HighValues.DataMember = DataSet_Obj.Tables["CandleTable"].Columns["High"].ToString();
Tag_Serie_Candle.LowValues.DataMember = DataSet_Obj.Tables["CandleTable"].Columns["Low"].ToString();
Tag_Serie_Candle.LabelMember = "Candle Chart";
Tag_Serie_Candle.CheckDataSource();
chartpie.AddView(chart, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MatchParent, ViewGroup.LayoutParams.MatchParent));
}
catch (Exception exe)
{
exe.Message.ToString();
}
}

You should do something as in the examples here:

I have found that, at the present moment, this is not working. I added the defect (ID566) list to be fixed as soon as possible (now fixed, see update at the bottom of the reply). If you register at Steema Software's Bugzilla system, you will be able to be in the CC List and be notified about status updates. In the meantime you can manually read values from the DataSet using this code:
Tag_Serie_Candle.DateValues.DateTime = true;
for (int i = 0; i < DataSet_Obj.Tables["CandleTable"].Rows.Count; i++)
{
DataRow row = DataSet_Obj.Tables["CandleTable"].Rows[i];
DateTime dt = Convert.ToDateTime(row["Date"]);
Double open = Convert.ToDouble(row["Open"]);
Double high = Convert.ToDouble(row["High"]);
Double low = Convert.ToDouble(row["Low"]);
Double close = Convert.ToDouble(row["Close"]);
Tag_Serie_Candle.Add(dt, open, high, low, close);
}
UPDATE: As of 11th February 2014, the defect has been fixed. Anyone interested in testing the solution please let me know.
