aspxgridview后台如何获取单选框的值，aspxgridview签前台代码如下。

    <dx:ASPxGridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="False" 
        DataSourceID="ObjectDataSource1" KeyFieldName="序列号" Theme="Office2003Blue" 
        Width="100%">
        <Columns>
            <dx:GridViewDataTextColumn FieldName="序列号" ReadOnly="True" VisibleIndex="1">
            </dx:GridViewDataTextColumn>
            <dx:GridViewDataTextColumn FieldName="评价指标" VisibleIndex="2">
            </dx:GridViewDataTextColumn>
            <dx:GridViewDataTextColumn FieldName="备用1" VisibleIndex="3">
            </dx:GridViewDataTextColumn>
            <dx:GridViewDataTextColumn FieldName="备用2" VisibleIndex="4">
            </dx:GridViewDataTextColumn>
            <dx:GridViewDataTextColumn VisibleIndex="5" FieldName="评价">
                <DataItemTemplate>
                    <dx:ASPxRadioButtonList ID="ASPxRadioButtonList1" runat="server" 
                        RepeatDirection="Horizontal" SelectedIndex="0">
                        <Items>
                            <dx:ListEditItem Text="1" Value="1" Selected="True" />
                            <dx:ListEditItem Text="2" Value="2" />
                            <dx:ListEditItem Text="3" Value="3" />
                            <dx:ListEditItem Text="4" Value="4" />
                        </Items>

GridView控件实现CheckBox选中删除数据示例
//GridView设置


asp:TemplateField



/asp:TemplateField






DataFormatString="{0:d}" />







/asp:GridView
//CheckBox设置
Font-Size="9pt" OnCheckedChanged="cbAll_CheckedChanged"
Text="全选/反选" />
Text="部分删除或全部删除" OnClick="btnDeleteMore_Click" onload="btnDeleteMore_Load"
Width="134px" />
OnClick="btnRre_Click" Width="126px" />
//cs页面设置绑定删除信息功能
SqlConnection sqlcon;//加载信息显示数据
