Filtering

[DayWalker]

Can anyone perhaps tell me why i am getting this error:

An unhandled exception of type System.Data.EvaluateException occurred in system.data.dll

Additional information: Cannot perform = operation on System.Decimal and System.String.

In this code:

With dsDataset.Tables("DataTable")
.DefaultView.RowFilter = "Field = " & txtSerialNum.Text & "%"
If .DefaultView.Count = 0 Then
MessageBox.Show("The Number does not exsist", "No Data", MessageBoxButtons.OK, MessageBoxIcon.Information)
End If
dgCallList.DataSource = .DefaultView
End With
