Assigning disabled image to ImageButton Control

Download demo project - 70.9 Kb

Introduction

As you know, in the ASP.NET ImageButton can not be displayed as disabled. I have written the below code in order to solve this problem.

With this control you can easily show a disabled ImageButton. You can assign four different values for imageURL in this control.

ImageURL
DisableImageURL
MouseOverImageURL
MouseOutImageURL

The code

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

namespace ImageButtonTest
{
    /// <SUMMARY>
    /// Summary description for WebForm1.
    /// </SUMMARY>

    public class WebForm1 : System.Web.UI.Page
    {

        protected msWebControlsLibrary.ExImageButton btnSave;
        protected msWebControlsLibrary.ExImageButton btnCancel;
        protected msWebControlsLibrary.ExImageButton btnNew;
        protected msWebControlsLibrary.ExImageButton btnDelete;
        protected msWebControlsLibrary.ExImageButton btnSearch;
        protected System.Web.UI.HtmlControls.HtmlGenericControl divMain;
        protected System.Web.UI.WebControls.TextBox kontrol;

        private void Page_Load(object sender, System.EventArgs e)
        {
            // Put user code to initialize the page here

            if (!Page.IsPostBack)
            {
                changedefault();
            }
        }

        #region Web Form Designer generated code

        override protected void OnInit(EventArgs e)

            // Web Form Designer.
            //

            InitializeComponent();
            base.OnInit(e);
        }

        /// <SUMMARY>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </SUMMARY>

        private void InitializeComponent()
        {    
            this.btnSave.Click += new
