Run Demo: MVCxGantt - Columns

Available column types:

Column Type	Description
GanttCommandColumn	A command column.
GanttCheckColumn	A column that displays Boolean values.
GanttColorEditColumn	A column that displays color values.
GanttDateTimeColumn	A data column that displays DateTime values.
GanttProgressBarColumn	A column that displays a progress bar.
GanttSpinEditColumn	A data column that displays numeric values.
GanttTextColumn	A data column that displays text values.
GanttTimeEditColumn	A data column that displays time portions of DateTime values.

Create a Column

Use the Add method to add a column to the Columns collection. Specify the column’s FieldName property.

C#

settings.SettingsTaskList.Columns.Add(new GanttTextColumn() { FieldName = "Subject", Caption = "Title", Width = Unit.Pixel(360) });
settings.SettingsTaskList.Columns.Add(new GanttDateTimeColumn() { FieldName = "StartDate", Caption = "Start", Width = Unit.Pixel(100), DisplayFormat = "MM/dd/yyyy" });

Access a Column

Use the Item[Int32] property to access individual columns by their index in the column collection.

C#

GanttTextColumn colFirstColumn = (GanttTextColumn)settings.SettingsTaskList.Columns[0];

Specify a Column Width

Use the ColumnMinWidth property to specify the minimum width for all columns in the Gantt.

C#

settings.SettingsTaskList.ColumnMinWidth = Unit.Pixel(45);

To specify the minimum width for an individual column, use the MinWidth property.

C#

settings.SettingsTaskList.Columns.Add(new GanttTextColumn() { FieldName = "Subject", Caption = "Title", MinWidth = Unit.Pixel(50) });

Column Editor

Each data column type has an editor in edit mode. For example, the GanttCheckColumn column allows you to edit Boolean values in a checkbox editor.

Use the column’s Properties[Editor_Name] property to access column editor settings.

C#

settings.Columns.Add(c => {
    c.FieldName = "Passengers";
    c.EditorProperties().SpinEdit(p => {
        p.MinValue = 0;
        p.MaxValue = 400;
    });
});
