Hey,
I nicked this from http://www.codeguru.com/vb/gen/vb_database/datagrid/article.php/c7587/
There is example code there also.
Quick example
Need a checkbox called cb ; index = 0 ; width & height = 190
datagrid = Grid
Private Sub Form_Load()
'My fourth column is the check box column
SetCheckboxes 3, cb
End Sub
Private Sub SetCheckboxes(ColNdx As Long, ByRef ChkboxArray As Object)
bInSetCheckboxes = True
On Error GoTo ErrorExit
Dim i
Dim obj As Object
Set obj = Grid
Dim OffsetX As Long, OffsetY As Long
If Not ChkboxArray(0).Container Is Grid.Container Then
CalcContainerOffset obj, OffsetX, OffsetY
End If
On Error Resume Next
With Grid
If (ChkboxArray.UBound <> .VisibleRows) Then
For i = ChkboxArray.UBound + 1 To .VisibleRows - 1
Load ChkboxArray(i)
ChkboxArray(i).Width = 190
ChkboxArray(i).Height = 190
Next
For i = .VisibleRows To ChkboxArray.UBound
Unload ChkboxArray(i)
Next
End If
OffsetX = OffsetX + (.Columns(ColNdx).Width - ChkboxArray(0).Width) / 2
OffsetY = OffsetY + 10 ''(.RowHeight - ChkboxArray(0).Height) / 2
.Columns(ColNdx).Alignment = dbgCenter
.Columns(ColNdx).Locked = True
'
If .LeftCol <= ColNdx Then
For i = 0 To .VisibleRows - 1
ChkboxArray(i).Value = Abs(.Columns(ColNdx).CellValue(.RowBookmark(i)))
ChkboxArray(i).Top = .Top + .RowTop(i) + OffsetY
ChkboxArray(i).Left = .Left + .Columns(ColNdx).Left + OffsetX
ChkboxArray(i).Visible = True
ChkboxArray(i).ZOrder
Next
Else
i = 0
End If
For i = i To ChkboxArray.UBound
ChkboxArray(i).Visible = False
Next
End With
ExitPoint:
bInSetCheckboxes = False
Exit Sub
ErrorExit:
Resume ExitPoint
