DataGrid Sort
Sorts the records in a datagrid form when clicking on the column header. Toggles between ascending/descending sort order.
Original Author: Daniel Gaudin
Assumptions
I assume that the connection is established and that the recordset has been opened.
Besides that I would really appreciate your feedback. Let me know if you have other ideas on how to accomplish this. I'd specially like to know if there is a "nicer" alternative to the nested if-statement.
Side Effects
Not that I could see ;)
API Declarations
Dim WithEvents adoPrimaryRS As Recordset
Code
Private Sub grdDataGrid_HeadClick(ByVal ColIndex As Integer)
Dim strColName As String
Static bSortAsc As Boolean
Static strPrevCol As String
strColName = grdDataGrid.Columns(ColIndex).DataField
' Did the user click again on the same column ? If so, check
' the previous state, in order to toggle between sorting ascending
' or descending. If this is the first time the user clicks on a column
' or if he/she clicks on another column, then sort ascending.
If strColName = strPrevCol Then
If bSortAsc Then
adoPrimaryRS.Sort = strColName & " DESC"
bSortAsc = False
Else
adoPrimaryRS.Sort = strColName
bSortAsc = True
End If
Else
adoPrimaryRS.Sort = strColName
bSortAsc = True
End If
strPrevCol = strColName
End Sub
