Mobile ASP.NET

Mar 15, 2010 11:53 AM|dieseldave|LINK

I am working on supplementing my web site with mobile forms. I am using the 51Degrees mobile detector to redirect mobile devices to pages designed to fit a mobile browser. I am only concerned wit smartphones I guess since they are the newest thing. I am using Keynotes MITE emulator to test. On one page I display a list of results for the current day. Using << >> buttons I increment the date and re-retrieve the list. This works fine when previewed from VS2008 and it does retrieve the first list in the emulator. However if i click >> or << it errors:

unspecified error message > 861 - Unsupported protocol > javascript:__doPostBack('LinkButton3','')

I am not sure which phone i am actually using, not that familiar with the emulator, but it seems to let me login, etc. The error seems to occur on the postback, but i think thathas been executed on other pages? Are there things you cant use on mobile pages?

Code:

public partial class mobi_todaysLogs : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        DateTime getdate;


        if (!IsPostBack)
        {
            getdate = Convert.ToDateTime("12/12/2006");
            //Label5.Text = getdate.ToShortDateString();
            getdata(getdate);


        }


    }


    private void getdata(DateTime getdate)
    {
        DataTable dtlogs = new DataTable();
        SqlConnection objConn = new SqlConnection(SqlDataSource1.ConnectionString);
        SqlCommand objCmd = new SqlCommand();
        objCmd.Connection = objConn;
        objCmd.CommandType = CommandType.StoredProcedure;
        objCmd.CommandText = SqlDataSource1.SelectCommand;
        objCmd.Parameters.Add("@DateStart", SqlDbType.DateTime).Value = getdate;
        objConn.Open();
        SqlDataAdapter objAdapter = new SqlDataAdapter(objCmd);
        objAdapter.Fill(dtlogs);
        objConn.Close();
        

        Repeater1.DataSource = dtlogs;
        Repeater1.DataBind();


    }
    protected void LinkButton1_Click(object sender, EventArgs e)
    {
        DateTime getdate = Convert.ToDateTime(Label5.Text);
        getdate = getdate.AddDays(-1);
        //Label5.Text = getdate.ToShortDateString();
        getdata(getdate);
    }
    protected void LinkButton3_Click(object sender, EventArgs e)
    {
        DateTime getdate = Convert.ToDateTime(Label5.Text);
        getdate = getdate.AddDays(1);
        //Label5.Text = getdate.ToShortDateString();
        getdata(getdate);
    }

Hello,

Try to test you page in Keynotes MITE emulator by selecting latest mobile phone of Blackberry or Nokai? See how it goes there.

Thanks
