Namespace: DevExpress.XtraScheduler

Assembly: DevExpress.XtraScheduler.v24.1.Core.dll

NuGet Package: DevExpress.Scheduler.Core

Declaration

C#

void SetValue(
    ISchedulerStorageBase storage,
    string columnName,
    object val
)

VB.NET

Sub SetValue(
    storage As ISchedulerStorageBase,
    columnName As String,
    val As Object
)

Parameters

Name	Type	Description
storage	ISchedulerStorageBase	A ISchedulerStorageBase instance that stores data for the object.
columnName	String	A String, that is the name of the data field.
val	Object	A Object, that is the new field value.

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 SetValue method together with the IPersistentObject.GetValue 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.
