Question

我正在使用gridview，我的问题是如果用户选择第二个复选框，用户只能在网格中选择一个复选框，我们将取消选中。我尝试javascript，但这不适合我，你能帮我，我怎么能这样做。以下是我的gridview

    <data:EntityGridView ID="gvService" Width="100%"  DataKeyNames="PriceSystemID" runat="server"
                                            OnRowEditing="GridView1_RowEditing" OnRowCommand="gvServices_ItemCommand" AutoGenerateColumns="False"
                                            OnRowDeleting="gvService_RowDeleting" ShowFooter="true" OnRowCancelingEdit="gvService_RowCancelingEdit" 
                                            >

一个基本问题（可能是您的答案）：如果用户只能选择一个，为什么要使用复选框。使用单选按钮代替正确的分组，浏览器将负责单一选择。希望我足够清楚。当用户有多个选择可供选择时，使用复选框，否则，使用单选按钮进行单选。

如何只检查gridview中的一个复选框
