Syntax

public class SourceListDescriptor : DescriptorBase, ICustomTypeDescriptor, IDisposable, ITypedList, IItemPropertiesSource

Constructors

SourceListDescriptor()

Initializes a new empty SourceListDescriptor.

Declaration

public SourceListDescriptor()

SourceListDescriptor(Object)

Initializes a new SourceListDescriptor and initializes the ItemProperties collection from properties of the specified list.

Declaration

public SourceListDescriptor(object list)

Parameters

Type	Name	Description
System.Object	list	A list from which the collection has to be created.

SourceListDescriptor(String, PropertyDescriptorCollection)

Initializes a new SourceListDescriptor and initializes the ItemProperties collection from properties of the specified System.ComponentModel.PropertyDescriptorCollection.

Declaration

public SourceListDescriptor(string name, PropertyDescriptorCollection itemProperties)

Parameters

Type	Name	Description
System.String	name	The name value.
System.ComponentModel.PropertyDescriptorCollection	itemProperties	A collection of properties.

SourceListDescriptor(Type)

Initializes a new SourceListDescriptor and initalializes the ItemProperties collection from properties of the specified type.

Declaration

public SourceListDescriptor(Type type)

Parameters

Type	Name	Description
System.Type	type	The Type value.

Properties

IgnoreSetItemProperties

Gets or sets a property indicating whether subsequent calls to SetItemProperties on this TableDescriptor should be ignored. The default is false. You should set this property True if you manually want to add/merge PropertyDescriptors. It will prevent that the grid does not reinitialize the ItemProperties with results from calls to ITypedList.GetItemProperties later on.

Declaration

public bool IgnoreSetItemProperties { get; set; }

Property Value

Type	Description
System.Boolean

ItemProperties

Gets or sets the System.ComponentModel.PropertyDescriptorCollection with properties for each record in the table.

Declaration

public virtual PropertyDescriptorCollection ItemProperties { get; set; }

Property Value

Type	Description
System.ComponentModel.PropertyDescriptorCollection

ItemPropertiesVersion

Gets or sets the version of the ItemProperties collection. This value is increased each time the ItemProperties collection is modified.

Declaration

public int ItemPropertiesVersion { get; set; }

Property Value

Type	Description
System.Int32

Name

Gets or sets the name of this table.

Declaration

public virtual string Name { get; set; }

Property Value

Type	Description
System.String

SourceListSet

Gets or sets a reference to a SourceListDescriptor. A SourceListSet manages multiple SourceListDescriptor objects (or TableDescriptor objects) that belong to the same Engine object.

Declaration

public SourceListSet SourceListSet { get; set; }

Property Value

Type	Description
SourceListSet

Methods

Dispose(Boolean)

Declaration

protected override void Dispose(bool disposing)

Parameters

Type	Name	Description
System.Boolean	disposing

Overrides

DescriptorBase.Dispose(Boolean)

GetName()

Gets the descriptor name.

Declaration

public override string GetName()

Returns

Type	Description
System.String	Descriptor name.

Overrides

DescriptorBase.GetName()

OnInitializeItemProperties(EventArgs)
