[goodmorningsky]

I make Validator : System.Web.UI.WebControls.CustomValidator

class.

and defined ValidationType property which is type of ValidateType.

I want to make the proerty is shown with Extended dropdown menu in properties window of Design mode.

I did following but, it doesn't show.

How can I do it?

 

using System;
using System.Web.UI; 
using System.ComponentModel;
namespace TestControls
{
/// <summary>
/// Summary description for Validator.
/// </summary>
[DefaultProperty("ValidationType")]
public class Validator : System.Web.UI.WebControls.CustomValidator
{
	public Validator()
	{
	}
	private ValidateType _validateType;
	[bindable(true), Browsable(true),
	Category("Appearance"),
	TypeConverter(typeof(ValidateType))]
	public ValidateType ValidationType
	{
		set
		{
			_validateType = value;
			switch(_validateType)
			{
				case ValidateType.Email:
					this.ClientValidationFunction="OnValidate_Email";
					this.ErrorMessage = "Test Error";
					break;
			}
		}
	}
}
}
using System;

namespace TestControls
{

public enum ValidateType
{
	Email = 1,
	Phone = 2,
}
}

You made our property writeOnly, place a "get" to allow "read" as well.
