Examples

The following code example demonstrates how the IDReferencePropertyAttribute attribute is applied to a property that evaluates to a string. In this example, the DataSourceID member identifies a data source control and therefore specifies the DataSourceControl type.

// This class implements a custom data source control.
public class SomeDataBoundControl : DataBoundControl
{   
    [ IDReferencePropertyAttribute(typeof(DataSourceControl)) ]        
    new public string DataSourceID {
        get {
            return base.DataSourceID;
        }
        set {
            base.DataSourceID = value;
        }
    }
}

' This class implements a custom data source control.
Public Class SomeDataBoundControl
    Inherits DataBoundControl
    
    <IDReferencePropertyAttribute(GetType(DataSourceControl))>  _
    Public Shadows Property DataSourceID() As String 
        Get
            Return MyBase.DataSourceID
        End Get
        Set
            MyBase.DataSourceID = value
        End Set
    End Property
    
End Class

Remarks

The IDReferencePropertyAttribute class is applied to properties that contain ID references. ContentPlaceHolderID is an example of a property that contains an ID reference. When this attribute is applied, designers can provide additional functionality during design time, such as listing IDs.
