Populating with Data Programmatically
Updated over 6 months ago
RadGanttview supports unbound mode as well, which means that you can manually populate it with the summary items, task items and milestone items (if needed). Then just set up the links between tasks and you have your gantt setup. The following example starts by setting the desired start and end range of the graphical element and then we are adding a few task items with sub items. At the end we are adding the links between the items.
C#
this.radGanttView1.GanttViewElement.GraphicalViewElement.TimelineStart = new DateTime(2010, 10, 9);
this.radGanttView1.GanttViewElement.GraphicalViewElement.TimelineEnd = new DateTime(2010, 12, 10);
//setup data items
GanttViewDataItem item1 = new GanttViewDataItem();
item1.Start = new DateTime(2010, 10, 10);
item1.End = new DateTime(2010, 10, 15);
item1.Progress = 30m;
item1.Title = "Summary task.1. title";
GanttViewDataItem subitem11 = new GanttViewDataItem();
subitem11.Start = new DateTime(2010, 10, 10);
subitem11.End = new DateTime(2010, 10, 12);
subitem11.Progress = 10m;
subitem11.Title = "Sub-task.1.1 title";
GanttViewDataItem subitem12 = new GanttViewDataItem();
subitem12.Start = new DateTime(2010, 10, 12);
subitem12.End = new DateTime(2010, 10, 15);
subitem12.Progress = 20m;
subitem12.Title = "Sub-task.1.2 title";
//add subitems
item1.Items.Add(subitem11);
item1.Items.Add(subitem12);
this.radGanttView1.Items.Add(item1);
GanttViewDataItem item2 = new GanttViewDataItem();
item2.Start = new DateTime(2010, 10, 12);
item2.End = new DateTime(2010, 10, 18);
item2.Progress = 40m;
item2.Title = "Summary task.2. title";
GanttViewDataItem subitem21 = new GanttViewDataItem();
subitem21.Start = new DateTime(2010, 10, 12);
subitem21.End = new DateTime(2010, 10, 13);
subitem21.Progress = 10m;
subitem21.Title = "Sub-task.2.1 title";
GanttViewDataItem subitem22 = new GanttViewDataItem();
subitem22.Start = new DateTime(2010, 10, 13);
subitem22.End = new DateTime(2010, 10, 18);
subitem22.Progress = 30m;
subitem22.Title = "Sub-task.2.2 title";
GanttViewDataItem subitem23 = new GanttViewDataItem();
subitem23.Start = new DateTime(2010, 10, 18);
subitem23.End = new DateTime(2010, 10, 18);
subitem23.Title = "Sub-task.2.3 title";
//add subitems
item2.Items.Add(subitem21);
item2.Items.Add(subitem22);
item2.Items.Add(subitem23);
this.radGanttView1.Items.Add(item2);
//add links between items
GanttViewLinkDataItem link1 = new GanttViewLinkDataItem();
link1.StartItem = subitem11;
link1.EndItem = subitem12;
link1.LinkType = TasksLinkType.FinishToStart;
this.radGanttView1.Links.Add(link1);
GanttViewLinkDataItem link2 = new GanttViewLinkDataItem();
link2.StartItem = subitem21;
link2.EndItem = subitem22;
link2.LinkType = TasksLinkType.StartToStart;
this.radGanttView1.Links.Add(link2);
GanttViewLinkDataItem link3 = new GanttViewLinkDataItem();
link3.StartItem = subitem22;
link3.EndItem = subitem23;
link3.LinkType = TasksLinkType.FinishToStart;
this.radGanttView1.Links.Add(link3);
Now we can just add the desired columns to be displayed in GanttViewTextViewElement. During the column initialization we will pass a string to specify the FieldName so the column will know which fields of the tasks to display. In addition this string will also be used as header text.
C#
GanttViewTextViewColumn titleColumn = new GanttViewTextViewColumn("Title");
GanttViewTextViewColumn startColumn = new GanttViewTextViewColumn("Start");
GanttViewTextViewColumn endColumn = new GanttViewTextViewColumn("End");
this.radGanttView1.GanttViewElement.Columns.Add(titleColumn);
this.radGanttView1.GanttViewElement.Columns.Add(startColumn);
this.radGanttView1.GanttViewElement.Columns.Add(endColumn);
