Hello everybody again!

I have a little problem with my report, the problem is that I have a
data in a datagridview. and next I import this information in to a
Crystal report but the time data do not appear in the repective column.

Let me show you a image to illustrate this case:




the code that i use is:

1) asign the datagridview source to a global dataset variable:

this.dataGridView2.DataSource = detaDs.Tables["dt"];
dataReport = new DataSet();
dataReport = detaDs;

2) Click button "Imprime" next I open a windows form with the report object and i make all operations to import the data into a report.

new TarjeteroSharp.Form3(this.dataReport).Show();

public Form3(DataSet myData)
        {
            InitializeComponent();
            myDataGlobal = myData;

            object result = TarjeteroSharp.WaitWindow.Show(this.workerMethod2);
            try { System.Console.Out.WriteLine(result.ToString()); }
            catch { System.Console.Out.WriteLine("No se puede imprimir result2"); }

            this.crystalReportViewer1.ReportSource = rpt1;
            this.crystalReportViewer1.Refresh();
            myData.Dispose();
            myDataGlobal.Dispose();

        }

        private void workerMethod2(object sender, TarjeteroSharp.WaitWindowEventArgs e)
        {
            this.showInfo2(myDataGlobal);
        }

        private void showInfo2(DataSet myData)
        {

            /*PREPARANDO LA DATA ANTES DE ASIGNARLA:*/
            myData.Tables[0].TableName = "tarjeta1";
            rpt1.SetDataSource(myData.Tables["tarjeta1"]);
        }

You can look I have a "tarjeta1" is a data_set the columns in this data
set is the same column in the datagridview

Please tell me if a rpt object (crystal object) have a properties and features
that formatting the cells to allow time data. because in my case this data dont appear in the report.

Thanks in advance.
