【源码】 gridview 里使用checkbox

<script language="javascript" type="text/javascript">
    function checkAll(chkContent)
    {
        var chkArray = document.getElementsByTagName("INPUT");
        var isCheck = chkContent.checked;
        
        for(var i = 0; i < chkArray.length; i++)
        {
            if(chkArray[i].type != "checkbox")
            {
                continue;
            }
            if(chkContent != chkArray[i])
            {
                chkArray[i].checked = isCheck;
            }
        }
    }


    </script>

 <asp:TemplateColumn HeaderText="全选">
    　　<HeaderTemplate>
            全选<asp:CheckBox ID="chkCheckAll" runat="server" onclick="checkAll(this)"/>
        </HeaderTemplate>
        <ItemTemplate>
            　　<asp:CheckBox ID="CheckBox1" runat="server"/>
        </ItemTemplate>
 </asp:TemplateColumn>

取值一 （控件anthem）

    protected void Button1_Click(object sender, EventArgs e)
    {
        bool bl = false;
        
        for (int i = 0; i < DataGrid1.Items.Count; i++)
        {
            bl = ((CheckBox)(DataGrid1.Items[i].Cells[2].FindControl("CheckBox1"))).Checked;
            if (bl)
            {
                string ObjectID = DataGrid1.Items[i].Cells[0].Text;
            }
        }

    }

取值二 

protected void Button1_Click(object sender, EventArgs e)
    {
        bool bl = false;
        
        for (int i = 0; i < DataGrid1.Rows.Count; i++)
        {
            bl = ((CheckBox)(DataGrid1.Rows[i].Cells[2].FindControl("CheckBox1"))).Checked;
            if (bl)
            {
                string ObjectID = DataGrid1.Rows[i].Cells[0].Text;
            }
        }
