gridview中的commandname

前台代码：

        <asp:GridView ID="ClientGridview" runat="server" AutoGenerateColumns="false" DataKeyNames="ClientID"
            Font-Size="Small" OnRowCommand="ClientGridview_RowCommand">
            <Columns>
                <asp:BoundField DataField="ClientID" HeaderText="客户ID" ReadOnly="true" />
                <asp:BoundField DataField="ClientName" HeaderText="客户名" />
                <asp:ButtonField CommandName="ShowTeam" HeaderText="团队信息" Text="团队信息" />
                <asp:ButtonField CommandName="ClientInfo" HeaderText="详细信息" Text="详细信息" />
            </Columns>
        </asp:GridView>

后台代码：

有两种操作：1.查看DetailsView中的信息（CommandName=ClientInfo）

                 2.转向另一个页面（CommandName=ShowTeam）

protected void ClientGridview_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        conn = ConfigurationManager.AppSettings["str"];
        con = new SqlConnection(conn);
        con.Open();
        int index = Convert.ToInt32((string)e.CommandArgument);
        int ClientID = Convert.ToInt32(ClientGridview.DataKeys[index].Value.ToString());
        Session["ClientID"] = ClientID;
        if ((string)e.CommandName == "ShowTeam")
            Response.Redirect("SearchTeamInfo.aspx");
        else
        {
            if ((string)e.CommandName == "ClientInfo")
            {
                da = new SqlDataAdapter("select * from client where ClientID='" + ClientID + "'", con);
                ds = new DataSet();
                da.Fill(ds, "Client");
                ClientDetailsView.DataSource = ds;
                ClientDetailsView.DataBind();         
            }
        }
        con.Close();
    }
