Flexgrid sort indicator

[glerner]

Is there a way to put an indicator on a row header (up or down) that shows which column grid is sorted (ascending/descending - similar to Windows Explorer)?

Thanks,
Glenn

Here is an example which will put ^ or v on a sorted column


' Useful for sorting da es and other occassions where you have
' to click on one column but sort by another
'
' Inputs:'TheForm is the form where you want the
'sorter works, usually its Me.
'ClickCol is the column # that is being clicked
'on and SortCol is the column # that will be
'sorted.
'ParamArray is an array of Booleans that represents how you want each column sorted. True
means sort as a string, False means sort as
numeric, and if you omit the paramter then it is
sorted as generic. Example True,True,,False
means the first two columns are sorted as a
string the third column is sorted as generic,
and the fourth is sorted as numeric. In this
case if there is more than 4 columns then the rest would get sorted as generic since
their parameter is missing.

The IsString array represents
how you want each column sorted. True
means sort as a string, False means
sort as numeric, and if you omit the
paramter then it is sorted as generic.
'' Example True,True,,False means the first two columns are sorted as a string
the third column is sorted as generic
and the fourth is sorted as numeric.



Public Sub SortFlex(TheForm As Form, FlexGrid As MSFlexGrid, ClickCol As Integer, SortCol As Integer, ParamArray IsString() As Variant)
Dim i As Integer
Dim Headline As String
Dim Ascend As Boolean
Dim Decend As Boolean
Const p As String = "^"
Const m As String = "v"

On Error Goto SortErr

TheForm.MousePointer = vbHourglass
FlexGrid.Col = SortCol

'cycle thru all the columns



'example
Call SortFlex(Me, MSFlexGrid1, MSFlexGrid1.Col, MSFlexGrid1.Col)


For i = 0 To FlexGrid.Cols - 1
Headline = FlexGrid.TextMatrix(0, i)
Ascend = Right(Headline, 1) = p
Decend = Right(Headline, 1) = m
If Ascend Or Decend Then Headline = Left(Headline, Len(Headline) - 1)


If i = ClickCol Then


If Ascend Then
FlexGrid.TextMatrix(0, ClickCol) = Headline & m


If UBound(IsString) < LBound(IsString) Then
FlexGrid.Sort = flexSortGenericDescending
Else


If IsString(i) Then
FlexGrid.Sort = flexSortStringDescending
Else
FlexGrid.Sort = flexSortNumericDescending
End If
End If
Else
FlexGrid.TextMatrix(0, ClickCol) = Headline & p


If UBound(IsString) < LBound(IsString) Then
FlexGrid.Sort = flexSortGenericAscending
Else


If IsString(i) Then
FlexGrid.Sort = flexSortStringAscending
Else
FlexGrid.Sort = flexSortNumericAscending
End If
End If
End If
Else
FlexGrid.TextMatrix(0, i) = Headline
End If
Next i
SortErr:
TheForm.MousePointer = vbNormal


If Err.Number <> 0 Then
MsgBox Err.Number & vbCrLf & Err.Description, vbCritical, "Sort Error"
End If
End Sub
