VB.NET property descriptions

bmains · February 12th, 2004, 04:28 PM

Hello,

When creating custom controls, how do you provide a default value and a description for a property in your control that you can see in Visual Studio .NET when the property is selected? I have seen that you can do it through the ComponentModel class, but is this the only way? If so, is there something special you have to be concerned with with that class? I remember trying to use it before, but had problems with it. This was a long time ago though...

I'm writing an ASP.NET control using VB.NET syntax.

Thanks,

Brian Mains

vb file:
---------------------
Imports System
Imports System.Web
Imports System.Web.UI

Namespace myControls

Public Class ShowColor: Inherits Control

Public Text As String
Public Color As String

Protected Overrides Sub Render( objTextWriter As HtmlTextWriter )
objTextWriter.AddAttribute( "Color", Color )
objTextWriter.RenderBeginTag( "Font" )
objTextWriter.Write( Text )
objTextWriter.RenderEndTag()
End Sub

End Class

End Namespace
---------------

HTML page:
<%@ Register TagPrefix="myControls" Namespace="myControls"
Assembly="ShowColor"%>

<html>
<head><title>DisplayShowColor.aspx</title></head>
<body>

<myControls:ShowColor
Text="Hello World!"
Color="Red"
Runat="Server" />

</body>
</html>

This is a very simple example but you should get the idea.

I was thinking more along the lines of how the System.ComponentModel namespace would allow you to do:

Code:

<...  Description:="a description"...>
Property Text As String
...

That's what I was looking for was an alternative way to do this outside the ComponentModel, or if I have to use the component model, are there any special considerations that I need to be aware of? I remember having problems with this class before.

Thanks.
