How to know when a button is clicked in C#

Question

Pls I need your help in some cases about button in C#. How can I know when a particular button is clicked. I want to use the if condition statement to write the event. So I want it to do something when particular button is clicked. I want to put all the code inside one function or class then I can call it anytime. For example

 

private void showPanel()
{
 if (dashPanelButton.Clicked == true)
{
dashPanel.Visible = true;
}
else if(studInfoBtn.Clicked == true)
{
studInfoPanel.Visible = true;
}
else
{
homePanel.Visible = true;
}

}

 Note the above code is just an assumption not really a working code. Just using it to explain myself
