Example

The code below shows how to initialize tree list and chart mappings.

C#

ganttControl1.TreeListMappings.KeyFieldName = "ID";
ganttControl1.TreeListMappings.ParentFieldName = "ParentID";
ganttControl1.ChartMappings.TextFieldName = "Text";
ganttControl1.ChartMappings.StartDateFieldName = "StartDate";
ganttControl1.ChartMappings.FinishDateFieldName = "FinishDate";
ganttControl1.ChartMappings.BaselineStartDateFieldName = "BaselineStartDate";
ganttControl1.ChartMappings.BaselineFinishDateFieldName = "BaselineFinishDate";
ganttControl1.OptionsView.ShowBaselines = true;
ganttControl1.ChartMappings.PredecessorsFieldName = "Predecessors";
ganttControl1.DataSource = GetTasks();

DataTable GetTasks() {
    DataTable table = new DataTable();
    DataColumn id = new DataColumn("ID", typeof(int));
    DataColumn parentId = new DataColumn("ParentID", typeof(int));
    DataColumn text = new DataColumn("Text", typeof(string));
    DataColumn start = new DataColumn("StartDate", typeof(DateTime));
    DataColumn finish = new DataColumn("FinishDate", typeof(DateTime));
    DataColumn startBaseline = new DataColumn("BaselineStartDate", typeof(DateTime));
    DataColumn finishBaseline = new DataColumn("BaselineFinishDate", typeof(DateTime));
    DataColumn predecessors = new DataColumn("Predecessors", typeof(string));
    table.Columns.AddRange(new DataColumn[] { id, parentId, text, start, finish, startBaseline, finishBaseline, predecessors });
    table.Rows.Add(new object[] { 1, 0, "Task 1", DateTime.Now, DateTime.Now.AddDays(1), DateTime.Now, DateTime.Now.AddDays(1.5), null });
    table.Rows.Add(new object[] { 2, 0, "Task 2", DateTime.Now.AddDays(1), DateTime.Now.AddDays(2), DateTime.Now.AddDays(1), DateTime.Now.AddDays(1.5), 1 });
    table.Rows.Add(new object[] { 3, 0, "Task 3", DateTime.Now.AddDays(2), DateTime.Now.AddDays(3), DateTime.Now.AddDays(2), DateTime.Now.AddDays(3), "1, 2" });
    return table;
}
