Greetings. I'll post as I do and see if it helps. First make sure your DataTable is bringing the bank data. Then change the code and test to see if it will work. The only difference I see is that you use DataTable teste and I use Collection .

private void frmRecategoria_Load(object sender, EventArgs e)
{
   DataTable teste = Ncategoria.Mostrar();

   //carrega a tabela do reportviewer
   reportViewer1.LocalReport.DataSources.Add(new Microsoft.Reporting.WinForms.ReportDataSource("NomeDoDataSet_doTablix", teste));

this.ReportViewer1.RefreshReport();
}

Make sure that in your table the columns have the same names as the DataTable , for example: CategoryID , CategoryCategory .
