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

}

}

}

Action里面：

private PromotionManageTo promotionManageTo

private List<PromotionManageTo>productClass

get…

set…

SqlMaps里面：

<select resultClass="promotionManage.PromotionManageTo">

……

</select>

JSP里面：

<s:iterator value="productClass" status="productClassLength">

<td>

<input type="checkbox" name="promotionManageTo.productId" value="<fs:property value="productId"/>" <c:if test="${fn:containsIgnoreCase(promotionManageTo.productId, productId)}">checked="checked"</c:if>/>

</td>

</s:iterator>
