遍历页面上所有TextBox控件并给它的Enabled赋值为false

private

void
FindSelecedControl(Control control)







{



if
(control
is
TextBox)







{



TextBox txt
=
(TextBox)control;



txt.Enabled
=

false
;



}



else







{



for
(
int
i
=

0
; i
<
control.Controls.Count; i
++
)







{



FindSelecedControl(control.Controls[i]);



}



}



}

页面调用方法：

foreach (Control control1 in this.Form.Controls)

{

FindSelecedControl(control1);

}
