Can someone help me in detecting changes in any form control in C #? I have many controls in one form, and I need to disable the button if any of the control values ​​in the form change.

foreach (Control c in this.Controls)
{
    c.TextChanged += new EventHandler(c_ControlChanged);

void c_ControlChanged(object sender, EventArgs e)

foreach (Control c in this.Controls)
{
    if (c is CheckBox)
    {
        ((CheckBox)c).CheckedChanged += c_ControlChanged;
