IPersistentObject.GetValue(ISchedulerStorageBase, String) Method

Obtains the value of the data field in the record bound to the current PersistentObject, supplied by the specified storage object.

Namespace: DevExpress.XtraScheduler

Assembly: DevExpress.XtraScheduler.v19.1.Core.dll

Declaration

C#

object GetValue(
    ISchedulerStorageBase storage,
    string columnName
)

VB.NET

Function GetValue(
    storage As ISchedulerStorageBase,
    columnName As String
) As Object

Parameters

Name	Type	Description
storage	ISchedulerStorageBase	A SchedulerStorageBase class instance that stores the data.
columnName	String	A String, that is the name of the data field.

Returns

Type	Description
Object	A Object, that is the field contents.

Remarks

If a persistent object storage is bound to a data source via its PersistentObjectStorage<T>.DataSource property, information about persistent objects (appointments or resources) is obtained from the data source’s data rows. In this case, the GetValue method obtains a value of the field in the data row that corresponds to the current persistent object. The required data field is specified by its name.

The GetValue method together with the IPersistentObject.SetValue and IPersistentObject.GetRow methods can be used to maintain an additional information about a persistent object. In this case, custom information can be stored within specific fields of the data source’s row.
