ControlValuePropertyAttribute.DefaultValue Property
.NET Framework (current version)
Gets the default value for the default property of a control.
Assembly: System.Web (in System.Web.dll)
When the property specified by the Name property is not set, use the DefaultValue property to determine the default value for the property.
The following code example demonstrates how to set the DefaultValue property by applying a ControlValuePropertyAttribute attribute to a custom control.
Imports System.ComponentModel Imports System.Web.UI Namespace Samples.AspNet.VB.Controls ' Set ControlValueProperty attribute to specify the default ' property of this control that a ControlParameter object ' binds to at run time. <DefaultProperty("Text"), ControlValueProperty("Text", "DefaultText")> Public Class SimpleCustomControl Inherits System.Web.UI.WebControls.WebControl Dim _text As String <Bindable(True), Category("Appearance"), DefaultValue("")> Property [Text]() As String Get Return _text End Get Set(ByVal Value As String) _text = Value End Set End Property Protected Overrides Sub Render(ByVal output As System.Web.UI.HtmlTextWriter) output.Write([Text]) End Sub End Class End Namespace
