jqGrid加checkbox,怎样实现动态显示和隐藏列，求大神指教或给个例子，谢谢谢谢。

protected void Page_Load(object sender, EventArgs e)

{

CheckBox chk = new CheckBox()

chk.Text = "testall" // 这里可以换成数据库的内容

chk.CheckedChanged += new EventHandler(chk_CheckedChanged)

chk.AutoPostBack = true

Page.Form.Controls.Add(chk)

for (int i = 0i <10i++)

{

CheckBox chk2 = new CheckBox()

chk2.Text = "test" + i.ToString() // 这里可以换成数据库的内容

chk2.Checked = (i % 3 == 0)// 这里可以换成数据库的内容

Page.Form.Controls.Add(chk2)

}

}

void chk_CheckedChanged(object sender, EventArgs e)

{

CheckBox all = sender as CheckBox

foreach(Control ctl in Page.Form.Controls)

{

if (ctl is CheckBox)

{

CheckBox chk = ctl as CheckBox

chk.Checked = all.Checked

}

}

}

{name:'hdryid',index:'hdryid', hidden:true, editable:true, editrules: { edithidden: true }, edittype:"select", editoptions:{dataUrl:"/jyxt/User/getJSJQComboxData.do"}, align:"center",sortable:true,width:120,formoptions:{rowpos:5, colpos:1}}
