public virtual DefaultBoolean AllowSort { get; set; }Property Value
| Type | Default | Description |
|---|---|---|
| DefaultBoolean | **Default** | One of the enumeration values. |
Available values:
| Name | Description |
|---|---|
| True | Corresponds to a Boolean value of true. |
| False | Corresponds to a Boolean value of false. |

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.
