Hello all. I have a programming issue with the truedbgrid filterbar. I have a custom search function tacked on to my grid so that I can search for numbers and words. That function is below. When I load my form is set the grid.FilterActive = True. When I start typing I get the following error "Missing operand before 'Like’ operator. The error comes from my custom filter function. The function works perfectly when I click on the filterbar and start typing but not when I set filteractive to true and start typing.
Dim sb As New System.Text.StringBuilder()
Dim dc As C1.Win.C1TrueDBGrid.C1DataColumn
For Each dc In _grid.Columns
If dc.FilterText.Length > 0 Then
Select Case dc.DataType.Name
Case "String"
If sb.Length > 0 Then
sb.Append(" AND ")
End If
sb.Append((dc.DataField + " like " + "’*" + dc.FilterText.ToString + "*’"))
Case "Int32", "Double", "Single"
If sb.Length > 0 Then
sb.Append(" AND ")
End If
sb.Append((dc.DataField + " = " + dc.FilterText.ToString))
Case Else
'dc.FilterText = ""
'TODO add other data types
End Select
End If
Next dc
' filter the data
Me.DT.DefaultView.RowFilter = sb.ToString
