ContextMenuStrip in c# tray application not reacting correctly when in expanded icon window

I have made a tray application with an icon that opens a ContextMenuStrip on Icon Click. I have three ToolStripMenuItem that can be clicked.
The Tray Application is working fine as long as the icon is visible directly. However if I have to click on the chevron to expand the non visible tray icons, I run into one Problem.
I can open the Menu by click on the Item. If I click on one of the ToolStripMenuItems the Tray-Menu goes into the Background of the Expanded Tray Icons and cannot be clicked anymore. How can I prevent this?
It seems the background is capturing the click rather then the openend form.
Here is the code for the Menu.
class Menu
{
private static ContextMenuStrip contextMenuStrip;
private static NotifyIcon notifyIcon1 = new NotifyIcon();
public Menu()
{
notifyIcon1.Icon = new Icon("icon.ico");
notifyIcon1.Text = "icon";
contextMenuStrip = new ContextMenuStrip();
ToolStripItem stripItem0 = new ToolStripMenuItem("open");
contextMenuStrip.Items.AddRange(new ToolStripItem[] { stripItem0 });
ToolStripItem stripItem1 = new ToolStripMenuItem("stop");
stripItem1.Click += new EventHandler(ToggleTracking);
contextMenuStrip.Items.AddRange(new ToolStripItem[] { stripItem1 });
ToolStripItem line = new ToolStripSeparator();
contextMenuStrip.Items.AddRange(new ToolStripItem[] { line });
ToolStripItem stripItem2 = new ToolStripMenuItem("close");
stripItem2.Click += new EventHandler(Close);
contextMenuStrip.Items.AddRange(new ToolStripItem[] { stripItem2 });
notifyIcon1.ContextMenuStrip = contextMenuStrip;
//notifyIcon1.ContextMenu = contextMenu1;
notifyIcon1.Click += new EventHandler(IconClick);
notifyIcon1.Visible = true;
}
private void ToggleTracking(object Sender, EventArgs e)
{
ToolStripMenuItem stripItem1 = (ToolStripMenuItem)contextMenuStrip.Items[1];
if (stripItem1.Text == "stop")
{
stripItem1.Text = "restart";
Batch.StopTimer();
}
else
{
stripItem1.Text = "stop";
Batch.RestartTimer();
}
}
private void Close(object Sender, EventArgs e)
{
Application.Exit();
}
private void IconClick(object Sender, EventArgs e)
{
Control strip = Sender as Control;
if (contextMenuStrip.Visible)
{
contextMenuStrip.Hide();
}
else
{
contextMenuStrip.Show(Cursor.Position);
}
}
}

I had to use the BringToFront method like this.
{
contextMenuStrip.Show(Cursor.Position);
contextMenuStrip.BringToFront();
}

Show an Icon beside an Item in ContextMenuStrip when its clicked

I wrote a windows form application which can change my GateWay automatically by executing two Batch files.
Problem is that I want to show "check.ico" icon beside the item in ContextMenu list when I click on it.
Here is my code :
public Form1()
{
InitializeComponent();
}
Image MenuStripImage = Image.FromFile(#"C:\Users\ALIENWARE\Documents\Visual Studio 2015\Projects\routerSelect\routerSelect\Check.ico");
NotifyIcon TrayIcon;
ContextMenuStrip TrayMenu;
private void Form1_Load(object sender, EventArgs e)
{
Image MenuStripExit = Image.FromFile(#"C:\Users\ALIENWARE\Documents\Visual Studio 2015\Projects\routerSelect\routerSelect\exit.ico");
this.WindowState = FormWindowState.Maximized;
this.ShowInTaskbar = false;
this.Hide();
TrayIcon = new NotifyIcon();
TrayMenu = new ContextMenuStrip();
TrayMenu.Items.Add("GreenPAcket").Click += new EventHandler(GreenpacketSelect);
//if (DLinkSelectcliced == true && GreenPacketSelected == false)
//{
TrayMenu.Items.Add(MenuStripImage);
//}
TrayMenu.Items.Add("D-Link DSL 2890AL 5GHz").Click += new EventHandler(DLinkSelect);
//if (GreenPacketSelected == true && DLinkSelectcliced == false)
//{
TrayMenu.Items.Add(MenuStripImage);
//}
TrayMenu.Items.Add("Exit", MenuStripExit).Click += new EventHandler(Exit);
TrayIcon.ContextMenuStrip = TrayMenu;
TrayIcon.Visible = true;
TrayIcon.Icon = new Icon(#"C:\Users\ALIENWARE\Documents\Visual Studio 2015\Projects\WindowsFormsApplication2\WindowsFormsApplication2\router.ico");
}
private void Exit(object sender, EventArgs e)
{
System.Windows.Forms.Application.Exit();
}
// bool DLinkSelectcliced = false;
private void DLinkSelect(object sender, EventArgs e)
{
// DLinkSelectcliced = true;
Process Proc = new Process();
Proc.StartInfo.FileName = (#"C:\Users\ALIENWARE\Documents\Visual Studio 2015\Projects\routerSelect\routerSelect\Dlink.lnk");
Proc.Start();
TrayMenu.Items.Add(MenuStripImage);
// GreenPacketSelected = false;
}
// bool GreenPacketSelected = false;
private void GreenpacketSelect(object sender, EventArgs e)
{
// GreenPacketSelected = true;
Process Proc = new Process();
Proc.StartInfo.FileName = (#"C:\Users\ALIENWARE\Documents\Visual Studio 2015\Projects\routerSelect\routerSelect\GreenPacket.lnk");
Proc.Start();
TrayMenu.Items.Add(MenuStripImage);
// DLinkSelectcliced = false;
}

If check.ico is a check mark, you don't need it for ContextMenuItem because it has option to show check mark, just enable CheckOnClick property for that item.
But if you want to show your custom icon instead, you must first convert it to image
You can do it yourself or use this method below to let C# do it for you
Use method here to convert icon to bmp image:
http://www.dotnetfunda.com/codes/show/967/icon-to-bitmap-in-csharp-winforms
Or simply create .png/.bmp version of this icon instead.
But first you should add this icons as resources to your project because if this icons will not exist in the location you gave it won't work (so you won't be able to use it on another PC).
To do it open solution explorer, right click on project and select properties, then go to resources, select icons, click Add Resource and add all icons.
Then to load icons from resources you simply type:
notifyIcon1.Icon = Properties.Resources.iconName
To show icon as image in your ContextMenuItem method in the link like this:
menu1ToolStripMenuItem.Image = ConvertFromIconToBitmap(Properties.Resources.iconName, new Size(16,16))
Btw, I glanced at your code and I think there is a lot of problems there...

Minimize to system tray

i was following the instruction on page
but then, there's no icon attached for the application, so after the form is hidden, i cannot reshow the form, since there's no icon on the system tray,
how do i resolve this ?
here is my code
private void Form1_Resize(object sender, EventArgs e)
{
if (FormWindowState.Minimized == this.WindowState)
{
notifyIcon1.Visible = true;
cmd.cetakSukses(ident.judul_App + " Diperkecil ke dalam System Tray");
notifyIcon1.BalloonTipText = ident.judul_App + " Diperkecil ke dalam System Tray";
notifyIcon1.BalloonTipTitle = ident.judul_App;
notifyIcon1.BalloonTipIcon = ToolTipIcon.Error;
notifyIcon1.ShowBalloonTip(500);
this.Hide();
}
else
{
}
}
update :
i have attached the icon, and the icon still not showing on the system tray
and i figured how to make the form showing, i need to add the following code to notifyicon
private void notifyIcon1_DoubleClick(object sender, EventArgs e)
{
this.Show();
}

You can set the notify icon at design using the Properties sheet:
Or you can add/change the icon property at runtime using the following code:
notifyIcon1.Icon = new Icon("appicon.ico");

This is how i implemented through code behind for a WPF app.
System.Windows.Forms.NotifyIcon m_NotifyIcon;
public StartWindow()
{
InitializeComponent();
m_NotifyIcon = new System.Windows.Forms.NotifyIcon();
m_NotifyIcon.Icon = new System.Drawing.Icon(IconPath);
m_NotifyIcon.Visible = true;
m_NotifyIcon.BalloonTipTitle = "Tip here";
m_NotifyIcon.Text = "Text here";
m_NotifyIcon.DoubleClick += delegate(object sender, EventArgs args)
{
this.Show();
this.WindowState = WindowState.Normal;
};
}
protected override void OnClosing(System.ComponentModel.CancelEventArgs e)
{
try
{
if (m_NotifyIcon != null)
m_NotifyIcon.Dispose();
}
catch { }
base.OnClosing(e);
}
protected override void OnStateChanged(EventArgs e)
{
if (WindowState == WindowState.Minimized)
this.Hide();
base.OnStateChanged(e);
}

You need to give you application an icon either by using visual studio or programatically.
You can do it in VS by going to the project properties and selecting the application tab
Or you can set it at runtime if you have icon files attached to your project already.
private NotifyIcon appIcon = new NotifyIcon();
appIcon.Icon = new System.Drawing.Icon("myApp.ico");

Save window state when application in tray

I have an app that minimizes to the system tray by clicking on "close" button and I want to save it's state (position, all elements (comboboxes, textboxes) with their values, etc).
Now I wrote this code, but it creates a new window from tray (instead of recovering the old one, with its parameters):
# app.xaml.cs:
this.ShutdownMode = ShutdownMode.OnExplicitShutdown;
// create a system tray icon
var ni = new System.Windows.Forms.NotifyIcon();
ni.Visible = true;
ni.Icon = QuickTranslator.Properties.Resources.MainIcon;
ni.DoubleClick +=
delegate(object sender, EventArgs args)
{
var wnd = new MainWindow();
wnd.Visibility = Visibility.Visible;
};
// set the context menu
ni.ContextMenu = new System.Windows.Forms.ContextMenu(new[]
{
new System.Windows.Forms.MenuItem("About", delegate
{
var uri = new Uri("AboutWindow.xaml", UriKind.Relative);
var wnd = Application.LoadComponent(uri) as Window;
wnd.Visibility = Visibility.Visible;
}),
new System.Windows.Forms.MenuItem("Exit", delegate
{
ni.Visible = false;
this.Shutdown();
})
});
How I can modify this code for my problem?

When you hold a reference to your `MainWindow´ then you can simple call Show() again after closing it. Closing the Window will simply hide it and calling Show again will restore it.
private Window m_MainWindow;
ni.DoubleClick +=
delegate(object sender, EventArgs args)
{
if(m_MainWindow == null)
m_MainWindow = new MainWindow();
m_MainWindow.Show();
};
If you´re sure that the MainWidnow is your Applications primary Window then you can also use this:
ni.DoubleClick +=
delegate(object sender, EventArgs args)
{
Application.MainWindow.Show();
};
I would prefer the first variant since it´s explicit.

C# NotifyIcon stays in tray after the Balloon Tip has been closed

after the Ballon Tip of my NotifyIcon has been close the icon still stays in tray.
It vanishes only when I hover it with my mouse cursor.
I have a class Notification.cs which has one component - NotifyIcon.
I call it from my Console Application as I only want to show the notification when certain conditions are fulfilled.
Some code:
how I call the notification from within my program:
Notification not = new Notification("Error occured, do this or that", "Some error", System.Windows.Forms.ToolTipIcon.Error);
not.getIcon().ShowBalloonTip(1000);
the notification class:
public Notification(string baloonTipText, string baloonTipTitle, System.Windows.Forms.ToolTipIcon icon) : this()
{
this.icon.Visible = true;
this.icon.BalloonTipText = baloonTipText;
this.icon.BalloonTipTitle = baloonTipTitle;
this.icon.BalloonTipIcon = icon;
}
public System.Windows.Forms.NotifyIcon getIcon()
{
return this.icon;
}
private void icon_BalloonTipClosed(object sender, EventArgs e)
{
this.icon.Visible = false;
this.icon.Dispose();
}
Any ideas?

Because you're running in a console application, your icon_BalloonTipClosed handler will not be invoked when the balloon tip is closed (no message pump). You will need to call Dispose manually either as your application exits or set a timer (System.Threading.Timer, System.Windows.Forms.Timer will not work) with a timeout longer than the balloon tip's timeout. e.g.:
timer = new Timer(state => not.getIcon().Dispose(), null, 1200, Timeout.Infinite);
