Having difficulty with asp:gridview

Question

I seem to be having difficulty with asp:querystringparameter and asp:gridview. I have the following so far and it just returns "no data available":

    protected void Page_Load(object sender, EventArgs e)
    {
        String strGroup = Request.QueryString["group"];

        switch(strGroup){
            case "Clients":
                ClientSource.SelectCommand = @"select client_code, 
                client_name from table1 where client_name = @phrase";
                break;
            case "Addresses":
                /*different query here*/
                break;
            case "Matters":
                /*different query here*/
                break;
            default:
                break;
        }

    }
</script>

    </div>
    </form>

Solution

you can bind gridview dynamically in code behind also. Try to debug if your query is returning any data. Is there any specific reason to use SqlDataSource?
