No problem, Rodolfo ...

First, you have to be sure to compile your project. Then, click on the Browse button (on the Customize ToolBox form) and find your .DLL that you just compiled.

>>Basically, you'll want a class library that contains your sub-classed UI controls, like textbox, button, etc. Something like this:
>>

>>using System;
>>using System.Data;
>>using System.Web;
>>using System.Web.UI.WebControls;
>>using System.Web.UI.HtmlControls;
>>
>>namespace MyCompany.WebUI.MyClasses
>>{
>>	public class MyLabel: System.Web.UI.WebControls.Label
>>	{
>>		private string m_MyProperty;
>>
>>		// properties
>>		public string MyProperty
>>		{
>>		   get {return this.m_MyProperty;}
>>		   set {this.m_MyProperty = value;}
>>		}
>>
>>	}
>>
>>	public class MyTextBox : System.Web.UI.WebControls.TextBox
>>	{
>>		// code here
>>	}
>>
>>	public class MyButton : System.Web.UI.WebControls.Button
>>	{
>>		// code here
>>	}
>>}
>>

>>
>>Add these to the ToolBox by right-clicking on the ToolBox and choosing Add/Remove Items.

>>>How could I create a class based on the system basic class "label", then drag and drop it on a web form, and finally be able to modify its methods and properties through the properties panel as I am used to doing with VFP.
