下面結(jié)合js實(shí)現(xiàn)單選.

呈現(xiàn)頁：

<asp:GridView ID="GridView1" Width="960px" EmptyDataText="暫無標(biāo)書可操作"
            DataKeyNames="ID" AutoGenerateColumns="false" runat="server" onrowdatabound="GridView1_RowDataBound"
            >
            <Columns>
                <asp:TemplateField HeaderText="選擇">
                    <ItemTemplate>
                    <asp:RadioButton ID="RadioButton1" runat="server"    />
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:BoundField DataField="ID" HeaderText="標(biāo)書編號" />

          </Columns>
  </asp:GridView>

代碼頁：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                RadioButton rb = (RadioButton)e.Row.FindControl("RadioButton1");
                if (rb != null)
                {
                  rb.Attributes.Add("onclick", "single(this)");  //single(obj)為js函數(shù) 
                }
            }

        }

需要添加的javascript函數(shù)：

<script type="text/javascript">
    var last=null;
    function single(obj)
    {
      if(last==null)    //第一次選擇RadioButton時賦id值給last
      {
         last=obj.id; 
      }
      else            //第一次以后的每一次都在這運(yùn)行，把上此的RadioButton.Checked=false,記下此次的obj.name
      {
        var lo=document.getElementById(last);
        lo.checked=false;
        last=obj.id;
      }
      obj.checked="checked";   //添加checked屬性，以便在上邊賦值為false
    }
    </script>
