Dim SelectFormula As String
SelectFormula = "{TABLE.FIELD1}='" & cmbName.Text & "' OR {TABLE.FIELD2}= '" & cmbName.Text & "' OR {TABLE.FIELD3}='" & cmbName.Text & "'"

CrystalReportViewer1.SelectionFormula = SelectFormula CrystalReportViewer1.ReportSource = CR
CrystalReportViewer1.Refresh()
CrystalReportViewer1.Visible = True
