Javascript实现GridView无刷新选择一行

用Javascript可以实现对GridView中某一行选择，而无需进行页面的刷新。
首先要在GridView的onrowdatabound的event handler中为GridView中的每一行onclick绑定event handler (Javascript)。假如GridView代码如下：
        <asp:GridView runat="server" id="GridViewCategory" AutoGenerateColumns="False"
    Width="100%" BackColor="#CCCCCC" BorderColor="#999999" BorderStyle="Solid"
    BorderWidth="3px" CellPadding="4" CellSpacing="2"
ForeColor="Black" onrowdatabound="GridViewCategory_RowDataBound">
        <RowStyle BackColor="White" />
        <Columns>
            <asp:BoundField DataField="Description" HeaderText="Category" />
        </Columns>
        <FooterStyle BackColor="#CCCCCC" />
        <PagerStyle BackColor="#CCCCCC" ForeColor="Black" HorizontalAlign="Left" />                       
        <HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
</asp:GridView>
onrowdatabound的event handler代码如下：
        protected void GridViewCategory_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            try
            {
                if (e.Row.RowType == DataControlRowType.DataRow)
                {
