How do i program so that it detect changes in cmb1,cmb2,cm3, tb1,tb2 and then when i click BTN cancel it will PROMPT to save yes/no [which i have already programed] if there is a change in either one of this[cmb1,cmb2,cm3, tb1,tb2] in runtime. and the program will close if there is no changes.

with reference to stored value in text file data.
[when I debug, the value stored in text file is displayed in cmb1,cmb2,cmb3,tb1,tb2]

So i would like to know how to do a program to BTNCANCEL_Click
that when it detected changes:

if (detect change)
{
using (SaveSetting settings = new SaveSetting())
                {
                    //read properties from dialogue
                    //when dialogue is yes it will run save and exit application
                    if (settings.ShowDialog() == DialogResult.Yes)
                    {
                        save();
                        Application.Exit();
                    }
                }
 
              }
else
{
   Close();
}
}

if (detect change) { using (SaveSetting settings = new SaveSetting()) { //read properties from dialogue //when dialogue is yes it will run save and exit application if (settings.ShowDialog() == DialogResult.Yes) { save(); Application.Exit(); } } } else { Close(); } }

There's events detect that
TextBox | TextChanged
ComboBox | SelectedIndexChanged
