Declaration
Returns
| Type | Description |
|---|---|
| Boolean | true, if an editor allows entering negative values; otherwise, false. The default is true. |
Remarks
Set the AllowNegativeValue property to false to prevent end users from entering negative TimeSpan values.
When a negative TimeSpan value is assigned to the editor’s EditValue directly, and the AllowNegativeValue property is set to false, the EditValue will not be converted to a positive value untill an end-user changes the EditValue using the time span mask.
