DataGrid中的CheckBox处理

<INPUT onclick="SelectDel('Form1')" type="checkbox" >全选

function SelectDel(form)
...{
        var checked = window.event.srcElement.checked;
        var i;
        var obj;
        form = eval(form);
        for(i=0;i<form.elements.length;i++)
        ...{
                obj = form.elements[i];
                if(obj.tagName == "INPUT")
                ...{
                        if(obj.name == "deleteid")
                        ...{
                                if(!obj.disabled)
                                obj.checked = checked;
                        }
                                
                }
        }
}    

 CheckBox的Checked属性为True时，绑定数据字段(id)

<asp:TemplateColumn HeaderText="删除">
<ItemTemplate>
<INPUT type=checkbox value='<%# DataBinder.Eval(Container.DataItem,"id") %>' name=deleteid>
</ItemTemplate>
</asp:TemplateColumn>

<asp:button id="Button_Del" runat="server" Text="删除选中"></asp:button>

private void Button_Del_Click(object sender, System.EventArgs e)
...{
    string delid = Request["deleteid"];
    if(delid != "")
    ...{
        string sql = "delete from Emp_CheckOnWork where id in("+ delid +")";
        DataClass dc = new DataClass();
        dc.ExecuteNonQuery(sql);
        DataGrid.CurrentPageIndex = 0;
        Bind();
        MessageBox.ShowOther(this,"删除成功!");
    }
    else
    ...{
        MessageBox.ShowOther(this,"删除失败!");
    }
}
