怎樣新增設定GridView，CheckBox全選功能
GridView內CheckBox控制元件全選設定
不需要新增後臺程式碼操作，前端即可完成設定，如下：
前端程式碼：
1.設定javascript。
<html xmlns="http://www.w3.org/1999/xhtml" >
<script type="text/javascript">
function CheckAll3(oCheckbox)
{
var GridView3 = document.getElementById("<%=GridView1.ClientID %>");
for(var i = 1; i < GridView1.rows.length; i++)
{
GridView1.rows[i].cells[0].getElementsByTagName("INPUT")[0].checked = oCheckbox.checked;
}
}
</script>
2.body內程式碼：
<asp:GridView ID="GridView1" runat="server" Height="2px" Width="720px" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="1" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging" OnRowDataBound="GridView1_RowDataBound" OnRowDeleting="GridView1_RowDeleting" AutoGenerateColumns="False" PageSize="8" >
<RowStyle ForeColor="#000066" />
<FooterStyle BackColor="White" ForeColor="#000066" />
<Columns>
