Gant Chart-Color Member Problem

[bora]

Hi,

I developed an application with Evaluation version of Pro2 for .Net... I used gant chart with a datatable as its datasource. Nothing was wrong with this application. But i when i purchased and set up the full version ColorMember attribute didn't work.
Is it a version problem? (I didn't changed the code)
Any idea?

Bora.

Hi Bora,

The problem may be because it is necessary to populate the NextTasks value list as shown here:

Code: Select all

		private void Form1_Load(object sender, System.EventArgs e)
		{
			tChart1.Axes.Bottom.Labels.Style=AxisLabelStyle.Value;
			CreateTable();
			LoadData();		
		}		

		private void CreateTable()
		{
			Random r=new Random(255);
			
			// Create DataTable
			sourceTable = new DataTable("sourceTable");
			colStart = new DataColumn("StartDates",Type.GetType("System.Double"));
			colEnd = new DataColumn("EndDates",Type.GetType("System.Double"));
			colYData = new DataColumn("YData",Type.GetType("System.Double"));
			colTask = new DataColumn("NextTask",Type.GetType("System.Double"));

			colDesc = new DataColumn("Desc",Type.GetType("System.String"));
			colColor = new DataColumn("Color",Type.GetType("System.Object"));

			sourceTable.Columns.Add(colStart);
			sourceTable.Columns.Add(colEnd);
			sourceTable.Columns.Add(colYData);
			sourceTable.Columns.Add(colDesc);
			sourceTable.Columns.Add(colColor);
			sourceTable.Columns.Add(colTask);

			// Add table items.
			DataRow NewRow;
			double lastVal=32000;
			for(int i = 0; i <10; i++)
			{
				Color cc=Color.FromArgb(r.Next(255),r.Next(255),r.Next(255));
				NewRow = sourceTable.NewRow();
				NewRow["Desc"] = "Label"+i.ToString();
				NewRow["StartDates"] = lastVal;
				NewRow["EndDates"] = lastVal+10;
				NewRow["YData"] = r.Next(10);
				NewRow["Color"] = cc;
				NewRow["NextTask"] = 0;
				sourceTable.Rows.Add(NewRow);
				lastVal=lastVal+5+r.Next(5);
			}
		}

		private void LoadData()
		{
			tChart1[0].Clear();
			gantt1.StartValues.DataMember = "StartDates";
			gantt1.EndValues.DataMember = "EndDates";
			gantt1.YValues.DataMember = "YData";
			gantt1.NextTasks.DataMember = "NextTask";
			gantt1.ColorMember = "Color";

			gantt1.DataSource = sourceTable;
			gantt1.CheckDataSource();
		}

Hi,

I'd set the NextTask's DataMember before. As i wrote my application was working in evaluation version. I installed Licensed Version and this problem occured. I didn't make any code change. I think problem is different. But what?

Thanks.

Hi Bora,

Could you please test if it works and if not let us know which error do you get and which TeeChart version are you using? As I mentioned before, the code above works for me here using latest TeeChart for .NET v2 release.
