Namespace: DevExpress.Web.Mvc

Assembly: DevExpress.Web.Mvc5.v19.1.dll

Declaration

C#

public TreeListCustomColumnDisplayTextEventHandler CustomColumnDisplayText { get; set; }

VB.NET

Public Property CustomColumnDisplayText As TreeListCustomColumnDisplayTextEventHandler

Property Value

Type	Description
TreeListCustomColumnDisplayTextEventHandler	A delegate method allowing you to implement custom processing.

Remarks

Use the CustomColumnDisplayText property to provide custom display text for any cell (for bound and unbound columns).

Initially, the DisplayText parameter returns null. To provide custom display text, assign the required string to this parameter. To get the current cell value, use the Value parameter.

The CustomColumnDisplayText event fires in two cases.

• When the control hierarchy is being built.
• When a grid is sorted by display text (the SortMode property is set to DisplayText).

C#

@Html.DevExpress().Gantt(settings => {
    ...
    settings.ClientLayout += (s, e) => {
        if (e.Column.FieldName != "Subject") return;
        if (Convert.ToString(e.Value) == "test_1")
          e.DisplayText = "test";
    };
    ...
}).Bind(GanttDataProvider.Tasks, GanttDataProvider.Dependencies, GanttDataProvider.Resources, GanttDataProvider.ResourceAssignments).GetHtml()
