Web custom control fired event problem

Question

User-266787045 posted

Hi,

i have a fired event problem in a web custom control, that code works with Visual Studio 2003 / framework 1.1.

But if i migrate the same code in Visual Studio 2005 / framework 2.0 it doesn't work.

The webform where i import the control can't catch the event "Conferma_Click_Event".  [:(]

Any solution?
 

using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ComponentModel;

namespace Ave
{
	[ToolboxData("&lt;{0}:CustomButton runat=server></{0}:CustomButton>")]

	public class CustomButton : WebControl
	{
		PlaceHolder oPlaceHolder = new PlaceHolder();
		Button oButton = new Button();

		// * OGGETTI EVENTO *
		private static readonly object Conferma_Click_Event = new object();

		[
		Category("Action"),
		Description("Evento scatenato al Click del bottone Conferma")
		]
		public event EventHandler Conferma_Click
		{
			add
			{
				Events.AddHandler(Conferma_Click_Event, value);
			}
			remove
			{
				Events.RemoveHandler(Conferma_Click_Event, value);
			}
		}


		public CustomButton()
		{
			CreateChildControls();
		}


		protected override void CreateChildControls()
		{
			oPlaceHolder.Controls.Clear();

			oButton.Click += new EventHandler(ConfermaOnClick);

			oPlaceHolder.Controls.Add(oButton);

			this.Controls.Add(oPlaceHolder);
		}

		private void ConfermaOnClick(object sender, EventArgs e)
		{
			if (Events != null)
			{
				EventHandler Evento = (EventHandler)(Events[Conferma_Click_Event]);
				if (Evento != null)
				{
					Evento(sender, e);
				}
			}
		}

		protected override void Render(HtmlTextWriter writer)
		{
			base.Render(writer);
		}
	}
}

Sometimes giving id to the controls will work.

Try with Implementing INamingContainer.
