public static string GetControlValue(Control ctl) {
	if (ctl.GetType() == typeof(TextBox)) {
		return ((TextBox)ctl).Text;
	}
	if (ctl.GetType() == typeof(RadioButtonList)) {
		return ((RadioButtonList)ctl).SelectedValue;
	}
	if (ctl.GetType() == typeof(CheckBox)) {
		return ((CheckBox)ctl).Text;
	}
	if (ctl.GetType() == typeof(DropDownList)) {
		return ((DropDownList)ctl).SelectedValue;
	}
	if (ctl.GetType() == typeof(HiddenField)) {
		return ((HiddenField)ctl).Value;
	}

	return "";
}
