GanttDataColumn.AllowSort Property

Specifies whether users can sort columns.

Namespace: DevExpress.Web.ASPxGantt

Assembly: DevExpress.Web.ASPxGantt.v23.2.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	Return Value
True	The value is true.	0
False	The value is false.	1
Default	The value is specified by a global option or a higher-level object.	2

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.
