BaseEdit.IsNotLoadedValue(Object) Method
Gets whether the specified value is the “Non-loaded Value”. This property is in effect when asynchronous data binding is used.
Namespace: DevExpress.XtraEditors
Assembly: DevExpress.XtraEditors.v18.2.dll
Declaration
Parameters
| Name | Type | Description |
|---|---|---|
| value | Object | A value to be tested. |
Returns
| Type | Description |
|---|---|
| Boolean | true if the specified value is the “Non-loaded Value”; otherwise, false. |
Remarks
During async data loading operations, editors (cells in container editors) may contain invalid values (for instance, if data hasn’t been loaded yet). In this instance, reading the editor’s (or cell’s) value will return a static object (“Non-loaded Value”), that tells you that the editor’s data hasn’t been loaded yet. You can check whether the returned value matches the static “Non-loaded Value” by calling the IsNotLoadedValue method.
