Hi, I Just need to know the modifications needed in the following  code so that I can make this a "component " in order to drag and drop on a form.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace BLLGeneric
{
    public class ValidateTitleClass
    {
        private static readonly ErrorProvider ErrorProvider = new ErrorProvider();

        public static void Validate(Control parent)
        {
            foreach (Control subcontrol in parent.Controls)
            {
                if (subcontrol is TextBox)
                {
                    var textbox = (TextBox) subcontrol;
                    var controltext = subcontrol.Name;
                    if (controltext == "Tbxdescription")
                    {
                        if (string.IsNullOrEmpty(textbox.Text))
                        {
                            ErrorProvider.SetError(subcontrol, "Field cannot be empty");
                        }
                    }
                    textbox.Text = null;
                }

                if (subcontrol.HasChildren)
                {
                    Validate(subcontrol);
                }
            }
        }

        public static object ClearErrorProvider()
        {
            ErrorProvider.Clear();
            ErrorProvider.Dispose();
            return null;
        }
    }
}

Are you looking for this to be an Extender Provider?

Inherit from Component in your class declaration:

public class ValidateTitleClass:System.ComponentModel.Component

Compile and the component will appear at the top of the Toolbox.

However, I do not see why you would make a component for a class that has only static methods. You gain nothing by doing so, since the methods in the class can be called at anytime in the application.
