In such cases you should put your code in a try/catch block and look at Exception and InnerExcception.

Probably you have error in assigning values, for example passing empty or null value to a parameter that is not allowed to be null or empty or a type mismatch.

To figure out the error, put your code in a try{}catch(Exception ex){} block and see ex.InnerException.Message it will show you to the main error.

Then to fix the problem, go to your report designer and make the parameter accept null and empty values or provide a suitable value for that parameter.

For example:

try
{
    ReportParameter param_DateFrom = new ReportParameter("DateTimePickerFrom", DateTimePickerFrom.Value.Date.ToShortDateString(), false);
    ReportParameter param_DateTo = new ReportParameter("DateTimePickerTo", DateTimePickerTo.Value.Date.ToShortDateString(), false);
    ReportParameter paramAccountNo = new ReportParameter("AccountNo", textBoxAccountNo.Text, false);
    ReportParameter paramNamefname = new ReportParameter("NameFname", textBoxName.Text, false);
    ReportParameter paramAddress = new ReportParameter("Address", textBoxAddress.Text, false);

    ReportParameter paramAccountType = new ReportParameter("AccounType", txtAccountType.Text, false);
    ReportParameter paramOpeningBalance = new ReportParameter("OpeningBalance", textBoxOpeningBalance.Text, false);
    //ReportParameter paramBankName = new ReportParameter("BankName",comboBoxBanks.SelectedText,false);

    this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] { param_DateFrom, param_DateTo, paramAccountNo, paramNamefname, paramAddress, paramAccountType, paramOpeningBalance });
    this.reportViewer1.LocalReport.Refresh();
    this.ReportBetweenDatesTableAdapter.Fill(this.DataSet1.ReportBetweenDates, Convert.ToInt32(comboBoxBanks.SelectedValue), DateTimePickerFrom.Value, DateTimePickerTo.Value);
    this.reportViewer1.RefreshReport();
}
catch (Exception ex)
{
    var message = ex.Message;
    if (ex.InnerException != null)
        message += "\n" + ex.InnerException.Message;
    MessageBox.Show(message );
}
