Answer 1

Check Modified property of TextBox on the TextChanged event. If true, the changes were made by user, otherwise the text was changed programmatically.

Example:

void Texbox_TextChanged(object sender, EventArgs e)
{
    if (((TextBox)sender).Modified)
        TextboxUserInput();
}

Answer 2

You can use the Key Down event of the text box.

  private void textBox1_KeyDown(object sender, KeyEventArgs e)
  {
      // Insert the code you want to run when the text changes here!
  }

Answer 3

avoid setting the "dirty" flag when done programmatically. Disable the event handler or set a flag that says "this is code, not the user"

Answer 4

try onBlur

this will catch the moment the user leaves the field.

You can work it up in conjunction with onFocus to save the value before editing
