Question

There is a check box in the datetimepicker control of winforms .net. But I could not find the event that is triggered when the check box is checked or unchecked . Is there a way

You´ll have to store the old "checked" value in order to compare to the new one, so you´ll be able to determine if the "checked" state has changed:

bool oldDateChecked = false; //if it's created as not checked

private void dtp_filtro_date_ValueChanged(object sender, EventArgs e)
{
    if (this.dtp_filtro_date.Checked != oldDateChecked)
    {
        oldDateChecked = this.dtp_filtro_date.Checked;
        //do your stuff ...

    }
}
