datagrid多个checkbox，如何当选择某一个checkbox时，其它都能选择

我们要实现一种效果，比如datagird中一行有多个checkbox，当我们想选择某一个checkbox，而其它也被选择，我们可以这样做
.首先添加3个模版列,分别为Ch1,Ch2,Ch3,如图

 1    <asp:TemplateColumn>
 2                                        <ItemTemplate>
 3                                            <asp:CheckBox  ID="Ch1" Runat="server"></asp:CheckBox>
 4                                        </ItemTemplate>
 5                                    </asp:TemplateColumn>
 6                                    <asp:TemplateColumn>
 7                                        <ItemTemplate>
 8                                            <asp:CheckBox ID="Ch2" Runat="server"></asp:CheckBox>
 9                                        </ItemTemplate>
10                                    </asp:TemplateColumn>
11                                    <asp:TemplateColumn>
12                                        <ItemTemplate>
13                                            <asp:CheckBox ID="Ch3" Runat="server"></asp:CheckBox>
14                                        </ItemTemplate>
15                                    </asp:TemplateColumn>

然后在datagrid的itemCreated事件中绑定程序

 1End Sub

下面为chkChanged绑定程序

 1End Sub

:
最后得到的界面如图所示:
