I want to filter a text in all columns in a datagridview. So I use Like % in the filter text. However, I found that the text(strFilter in my code) may contain % sometimes. So it have a syntax error. How can I use filter with like clause when the filter text contains %? 

```
    Private Sub PassFilter(ByRef dataTable As DataTable, ByVal strFilter As String)
    Try
        Dim dataview As DataView = dataTable.DefaultView
        Dim strExp As String = ""
        For Each col As DataColumn In dataTable.Columns
            If Not String.IsNullOrEmpty(strFilter) Then
                If strExp = "" Then
                    strExp += "[" & col.ColumnName & "]" & " LIKE '%" & strFilter & "%'"
                Else
                    strExp += " OR " & "[" & col.ColumnName & "]" & " LIKE '%" & strFilter & "%'"
                End If
            End If
        Next

        dataview.RowFilter = strExp

    Catch ex As Exception
        ShowMessage("Unable to filter datagridview." + ex.Message)
    End Try

End Sub

```
