Namespace: DevExpress.Web.ASPxGantt

Assembly: DevExpress.Web.ASPxGantt.v21.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

[DefaultValue(DefaultBoolean.Default)]
public virtual DefaultBoolean AllowSort { get; set; }

VB.NET

<DefaultValue(DefaultBoolean.Default)>
Public Overridable Property AllowSort As DefaultBoolean

Property Value

Type	Default	Description
DefaultBoolean	Default	One of the enumeration values.

Available values:

Name	Description
True	true. DefaultBoolean.True has a constant value of 0, while the standard true value corresponds to a value of 1. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
False	false. DefaultBoolean.False has a constant value of 1, while the standard false value corresponds to a value of 0. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
Default	The default behavior determined by the control’s logic.

Remarks

The ASPxGantt allows you to sort data by multiple columns.

Set the AllowSort property to True or False to allow or deny users to sort data in an individual column. If the property value is Default, the setting depends on the AllowSort property value.

Example

Set a column’s AllowSort property to true. Use the SortIndex and SortOrder properties to specify the column’s sort index and order.
