VSTO Ribbon - general/abstract button click event?

In a C# VSTO Ribbon, you can design and place buttons and you can program whatever you want each button to do i.e. an action that will occur on each individual button click event can be defined by the programmer.
I have some code I would like to perform every time a button was clicked -
regardless of which button was clicked. A simple example includes measuring the time that the button click event was received: I want this for all my buttons, so, I am looking for a general / abstract event handling all button clicks or something of the sort rather than each event one by one. Does this exist in VSTO or is there a clean implementation to it?
Here is a simple illustration of the problem in code.
I have 3 buttons: btn1, btn2 and btn3. And I have defined what I will do for each click as follows:
private void btn1_Click(object sender, RibbonControlEventArgs e)
{
//same code
//btn1 specific code
}
private void btn2_Click(object sender, RibbonControlEventArgs e)
{
//same code
//btn2 specific code
}
private void btn3_Click(object sender, RibbonControlEventArgs e)
{
//same code
//btn3 specific code
}
The problem is clear: there is part of the code that I want to do that is the same for each click. So is there a general click event where I can define the same code only just once?

How to add an event on a menu in C# project?

I have a C# Windows Forms App that contain a menu bar.
I want to display a Help Message when I press on the "HELP" menu button.
All that I can see when I press view code is this:
private void aboutToolStripMenuItem_Click(object sender, EventArgs e)
{
}
I think that I need to create inside the function a MessageBox or an event that will display the desired message.
Do you have any idea how should I do this, please?

Below should work for what your asking. If you are on your form you can double click the button you want to interact with, and Visual Studio should take you to the empty method.
private void helpToolStripMenuItem_Click(object sender, EventArgs e)
{
MessageBox.Show("This is supposed to be helpful");
}

How do I fire up CellContentDoubleClick in C#?

I'm using VS 2010 C#.
I have a form that only has a grid connected to a table. Basically, my idea is to select a row by double clicking it. Then later copy the ID and close the form to proceed to another form. But it is not working as per my test on doubleclick event on grid. It is suppose to show a Message box but it is not triggering.
I'm still new on C# and I've browsed the net for similar problem but most of the example are in VB, there was even one suggestion for me to make dgv a readonly=false (implemented on code).
Here is my code:
...
private void Form1_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'cISDataSet.tbl_Person' table. You can move, or remove it, as needed.
this.tbl_PersonTableAdapter.Fill(this.cISDataSet.tbl_Person);
this.dataGridView1.ReadOnly = false;
}
private void DataGridView1_CellContentDoubleClick(Object sender, DataGridViewCellEventArgs e)
{
MessageBox.Show("test");
}
...
I do not have any syntax error on my program.

Add this line to your form1_load. (after this.dataGridView1.ReadOnly = false;)
dataGridView1.CellContentDoubleClick += DataGridView1_CellContentDoubleClick;
You only need to tell the data grid view where to go when a double click happens.

How do you PerformClick(); for a button on a different tab?

I'm using Visual c# express 2010, I have 3 tabs and on the first tab there is a button that exits the program. I'm trying to call that button click on the 2nd and 3rd tab with
btnExit.PerformClick();
but since it isn't visible nothing happens. How would I call the invisible button click?
any help would be appreciated
EDIT:
Thanks for the replies, the two answers work great but I found a way that I think is easier and better.
instead of systematically changing tabs or calling a whole different method, I did this
btnExit_Click(sender, e);
I can put that in any other button click and it works great, very simple to.

I think it's better to create a method that actually has the code to exit the program, and call that method from btnExit click event and also other buttons click event, than PerformClick of the exit button.
void ExitApplication()
{
// code to exit the application
}
protected void btnExit_Click(object sender, EventArgs e)
{
ExitApplication();
}
protected void ButtonInOtherTab_Click(object sender, EventArgs e)
{
ExitApplication();
}
This way it's easier to read and understand.

myTabs.SelectedTab = specificTab;
btnExit.PerformClick();

How do I handle an event in C# based on a cell click in a DataGridView?

FYI, I looked at existing postings and I did not find exactly what I needed.
I am using Visual Studio 2008 to write a C# Windows Forms program. I have a DataGridView object that displays data from a table. When a user clicks on a cell I want to be able to grab the contents of that cell.
How do get an action to take place whenever there is a click on any cell in the datagridview. If the user clicks on the same cell 5 times in a row, I want the action to happen five times.
I am not even sure what the name of the event handler would be.
I tried the following, but it didn't work.
This was the code on the FormName.cs file:
private void DATASOURCEDataGridView_CellContentClick(object sender,
DataGridViewCellEventArgs e)
{
MessageBox.Show("clicked");
}
This was the code on the FormName.Designer.cs File:
this.DATASOURCEDataGridView.CellContentClick +=
new System.Windows.Forms.DataGridViewCellEventHandler(
this.DATASOURCEDataGridView_CellContentClick);
Thanks for the help!

Use the CellClickedEvent:
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
MessageBox.Show(dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString());
}
