.net RadioButtonList赋值

Repeater中的RadioButtonList如何进行赋值，使之选择某一项。比如数据库中数据为“关闭”，使他选择“关闭”这一项。能否在前台页面Repeater中使用Eval（“”）进行？

<asp:RadioButtonList ID="RadioChanStatus" runat="server" RepeatDirection="Horizontal" >
                            <asp:ListItem>开放</asp:ListItem>
                            <asp:ListItem>关闭</asp:ListItem>
                            <asp:ListItem>隐藏</asp:ListItem>
                        </asp:RadioButtonList>

repeater itemdatabound事件 搞定

protected void Button1_Click ( object sender , EventArgs e ) { if ( this.TextBox1.Text == "1" ) { this.myRadio.SelectedIndex = 1; } else { this.myRadio.SelectedIndex = -1; } }
