Separating NotifyIcon_Click and ItemMenu_Click events

I have an application which runs mostly within the taskbar, and its icon may be left clicked in order to open a Windows form.
The NotifyIcon also has a few MenuItems which can be accessed by right clicking, and each have their own click events to serve their functionality.
private void menuItem4_Click(object Sender, EventArgs e)
{
if (programEnabled == false)
{
programEnabled = true;
Console.WriteLine("Enabled!");
}
else
{
programEnabled = false;
Console.WriteLine("Disabled!");
}
}
//Icon clicked!
private void notifyIcon1_MouseClick(object Sender, EventArgs e)
{
//Reopen the form
Form f = new TemperForm();
}
Every time a MenuItem click event is activated however, NotifyIcon_Click also runs and I need that event for opening the Windows form. I don't want every time I click any MenuItem to also run the code that I wish to run when the icon is clicked.
How can I still use the NotifyIcon_Click event while not having it run every time I click a MenuItem?
I've been at this for hours and it's driving me up the wall!

Do NOT hide soft keyboard while tapping controls in WP

I have this piece of code for button in my Windows Phone 8.1 Store App project (not the Silverlight):
private void CursorRightButton_Click(object sender, RoutedEventArgs e)
{
if (string.IsNullOrWhiteSpace(QueryTextBox.Text)) return;
QueryTextBox.Focus(FocusState.Keyboard); //also i tried FocusState.Pointer
QueryTextBox.Select((TextBox.SelectionStart + 1) % (TextBox.Text.Length + 1), 0);
}
As you can see, I am tring to move cursor to right in text programmatically and the problem is that it hides soft keyboard and then shows it again after tapping button. I need to have keyboard on while tapping this button.
I tried to tinker with Focus() methods for sender and TextBox objects but I couldn't find any possible solution.
So the question is, how do you force keyboard not to loose focus/not to hide while tapping on controls?

I found out with Sajeetharans help that I need to set IsTabStop value on controls to false. Then keyboard will stay there. I did it in constructor of my page like this
public MainPage()
{
InitializeComponent();
CursorLeftButton.IsTabStop = false;
CursorRightButton.IsTabStop = false;
}
and my button method
private void CursorRightButton_Click(object sender, RoutedEventArgs e)
{
if (string.IsNullOrWhiteSpace(TextBox.Text)) return;
TextBox.Select((TextBox.SelectionStart + 1) % (TextBox.Text.Length + 1), 0);
}

Add a loaded event to your container say grid,
private void Grid_Loaded(object sender, RoutedEventArgs e)
{
this.IsTabStop = true;
set focus on the control , say a textblock
Txtblock1.Focus();
}

C# Tabless Control Previous/Back/Return Button failing?

I am hoping someone here can help me, i have a Tabless Control on my windows forms application and basically because the tabs are purposely hidden i have added 2 buttons to each tab "Next" and "Back".
This is the code snippet i have for my "Next" button:
private void nextbutton1_Click(object sender, EventArgs e)
{
tabControl1.SelectedTab = tabPage3;
this.toolStripStatusLabel8.Text = System.DateTime.Now.ToString();
}
Which works fine, however when i use the exact same theory on the "Back" button it does not work:
private void backbutton1_Click(object sender, EventArgs e)
{
tabControl1.SelectedTab = tabmain;
this.toolStripStatusLabel1.Text = System.DateTime.Now.ToString();
}
So my question is how does one go to a previous tabpage from a button? I have looked through here and tried all of the links that came up but nothing has worked any ideas?

You should use the SelectedIndex property instead of using concrete TabPage instances. This way it will still work when you decide to change the order of the pab pages or add new pages:
private void previousButton_Click(object sender, EventArgs e)
{
if (tabControl1.SelectedIndex > 0)
{
tabControl1.SelectedIndex--;
}
}
private void nextButton_Click(object sender, EventArgs e)
{
if (tabControl1.SelectedIndex < tabControl1.TabCount - 1)
{
tabControl1.SelectedIndex++;
}
}
Since there is no "Tabless" tab control in .NET Framework I can only assume that it works similar to the standard TabControl. If the solution doesn't work you should give us some information about the actual class you use.
BTW: There is no need to repeat the buttons on each page. Why don't you just put the buttons outside the TabControl?
Also: I see that you use a ToolStripStatusLabel to show the current time. Instead of updating it each time the user clicks somewhere add a Timer to your form. Set its Interval to 1000 and handle its Tick event. Update the label there:
private void timer1_Tick(object sender, EventArgs e)
{
toolStripStatusLabel1.Text = DateTime.Now.ToLongTimeString();
}
This way it updates constantly and again there is no need to repeat anything. You need to call timer1.Start() in the form's constructor.

How to detect a MenuStrip's open and close states ?

I need to detect whenever the MenuStrip (NOT a contextmenu) is opened and closed. The Enter and Leave events do not seem to work.
Why I need it:
I use a MenuStrip with options like "File", "Edit", "About", etc. But when the menu strip is active, and the user navigates through it using either the mouse or keyboard the other controls on the Windows Form also respond to it.
For example: I click the "Edit > Paste Special.. > Unformatted text" in my application using the mouse. But below the expanded menu item is a XNA 2d-rendering control that also detects the mouse input and does something that I don't want it to do. Now if I could just detect whenever the menu is opened I could disable/enable the appropriate controls.

Without knowing a little more about what you are doing, you can try the code below:
private void Form1_Load(object sender, EventArgs e)
{
menuStrip1.GotFocus += new EventHandler(MenuStrip1_GotFocus);
menuStrip1.LostFocus += new EventHandler(MenuStrip1_LostFocus);
}
private void MenuStrip1_GotFocus(object sender, EventArgs e)
{
textBox1.Text = "Has Focus";
}
private void MenuStrip1_LostFocus(object sender, EventArgs e)
{
textBox1.Text = "Lost Focus";
}
private void menuStrip1_MenuActivate(object sender, EventArgs e)
{
textBox1.Text = "Has Focus";
}
private void menuStrip1_MenuDeactivate(object sender, EventArgs e)
{
textBox1.Text = "Lost Focus";
}
This seems to be working for what you have described above. If you have the menu strip with tab stop on (true) then the got focus events will handle this case. If you only need to make changes if the mouse is used then Menu Active events should work.

How to determine which form was brought to front by clicking it?

I have an application with a Panel containing children Form objects. When I click one of the children Form it brings to front. I would like to know which one is in front now...
I've looked in event list but cant find proper event form my purpose :(
These methods doesn't work:
protected void OpenedFileForm_Enter(object sender, EventArgs e)
{
MessageBox.Show("enter");
}
protected void OpenedFileForm_Click(object sender, EventArgs e)
{
MessageBox.Show("click");
}
protected void OpenedFileForm_Activated(object sender, EventArgs e)
{
MessageBox.Show("activated");
}
protected void OpenedFileForm_MouseClick(object sender, MouseEventArgs e)
{
MessageBox.Show("mouse click");
}
protected void OpenedFileForm_Shown(object sender, EventArgs e)
{
MessageBox.Show("shown");
}
OpenFileDialog openFile1 = new OpenFileDialog();
openFile1.DefaultExt = "*.txt";
openFile1.Filter = "TXT Files|*.txt|RTF Files|*.rtf";
if (openFile1.ShowDialog() == System.Windows.Forms.DialogResult.OK &&
openFile1.FileName.Length > 0)
{
switch (Path.GetExtension(openFile1.FileName))
{
case ".txt":
txtForm childTXT = new txtForm();
this.childForms.Add(childTXT);
childTXT.Parent = this.mainPanel;
childTXT.richTextBox1.LoadFile(openFile1.FileName, RichTextBoxStreamType.PlainText);
childTXT.Show();
break;
}
}

Have you tried the Form.Activated Event?
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.activated(v=vs.80).aspx
Edit:
If you are in an MDI application, you might need to use MdiChildActivate instead.
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.mdichildactivate.aspx

This code can only work when you set the Form.TopLevel property to false. Which makes it turn into a child control, almost indistinguishable from a UserControl.
This has many side-effects, for one there is no notion of "front" anymore. The Z-order of child controls is determined by their position in their parent's Controls collection. And it affects the events it fires, Activated and Deactivated will never fire. Furthermore, the Form class was designed to be a container control, it doesn't like taking the focus itself. Its child controls get the focus, the Form class doesn't have any use for focus. Which is why the Enter, Click and MouseClick events don't fire, they are events that require focus.
Long story short, what you are trying to do doesn't make a wholeheckofalot of sense. If it is strictly the Z-order you want to fix then write an event handler for the MouseDown event:
void OpenedFileForm_MouseDown(object sender, MouseEventArgs e) {
var frm = (Form)sender;
frm.BringToFront();
}
You could add frm.Select() to get the Enter event to fire, but only do that if the form doesn't contain any focusable controls itself. Do note that there is evidence that you don't assign the events correctly in your code. The Shown event does fire. It is also important that you set the FormBorderStyle to None, the title bar cannot indicate activation status anymore.

Ok, I got this! Thx for help everyone. You gave me a hint to think about equity of my strange MDI idea where Panel is parent for other Forms. I Removed SplitContainer containing Panel and just did standard MDI application, where Forms are MDIChildren of main Form.
childTXT.MdiParent = this;
