Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v24.1.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public virtual bool? IsObjectFitForCollection(
    object obj
)

VB.NET

Public Overridable Function IsObjectFitForCollection(
    obj As Object
) As Boolean?

Parameters

Name	Type	Description
obj	Object	An object that must be checked against the criteria contained in the Criteria dictionary.

Returns

Type	Description
Nullable<Boolean>	true if the specified object satisfies the criteria contained in the Criteria dictionary; false if the object does not satisfies the criteria; null if it cannot be determined.

Remarks

This method returns a Nullable<Boolean>-type value. So, it can actually return null (Nothing in VB) if the specified object cannot be checked against the criteria contained in the Criteria dictionary.

When implementing a custom Collection Source, override this method to determine whether the specified object satisfies the criteria contained in the Criteria dictionary.

This method is intended for internal use.
