Here is my code. when I am running the application it through an error

An error occurred during a local report processing the definition of the report is invalid. An unexpected error occurred in report processing. The external component has thrown an exception.

private void frmCoopReportviewer_Load(object sender, EventArgs e)
{
try
{
string strDataSourceName = string.Empty;
foreach (ReportDataSource rds in reportViewer1.LocalReport.DataSources)
{
strDataSourceName = rds.Name.Trim();
}

reportViewer1.LocalReport.DataSources.Clear();

ReportDataSource reportDS = new ReportDataSource("CoopDataSet");
reportDS.Value = _datasourcelist.Rows;

reportViewer1.LocalReport.DataSources.Add(reportDS);

this.reportViewer1.RefreshReport();
}
catch (System.Exception err)
{
MessageBox.Show(err.Message);
}
this.reportViewer1.RefreshReport();
this.reportViewer1.RefreshReport();
}

What I have tried:

I need to display the report. before with the same code, I generate a report and download the pdf also but know I face this problem.
