Call the different report "tables" or "datasets" from within the rdlc, swap
the displayed report tables with parameters passed into the reportviewer.
private void ButtonTableA_Clicked(object sender, EventArgs e)
{
SetSelectedTable("TableA", sender, e);
}
private void ButtonTableB_Clicked(object sender, EventArgs e)
{
SetSelectedTable("TableB", sender, e);
}
private void SetSelectedTable(string TableName, object sender,
EventArgs e)
{
ReportParameter p = new
ReportParameter("SelectedTable", TableName);
this.reportViewer1.LocalReport.SetParameters(new
ReportParameter[] { p });
this.reportViewer1.RefreshReport();
}
