ListView groups with totals and subtotals

[makis_best]

Hi.

I have a ListView with groups.
Groups have columns with prices.

How I can do subtotals and totals at the end of every column and any group?
Any example?


Thank you.

1) you'll need to make the subtotals yourself. this isn't goign to go "automatically"
If this needs to be at the bottom, then either:
- enable the group footer and put the subtotal in there.
THis may not be visually entirely what you want since it won't be aligned with the columns.
- or add a subtotal item to the group

2) there's no provision in listcontrol for a grand total
you can add an extra "total" group and add a total item
or
have the total displayed outside of the listcontrol.

Thank you.

I find the solution
' Add a group with totals
Dim TotalSum, TotalSum1 As Double
Dim TempDbl As Double
TotalSum = 0
TotalSum1 = 0
For Each strmyGroupname In ListView1.Items
If Double.TryParse(strmyGroupname.SubItems(7).Text, TempDbl) Then TotalSum += TempDbl
If Double.TryParse(strmyGroupname.SubItems(8).Text, TempDbl) Then TotalSum1 += TempDbl
Next
Dim gp As ListViewGroup
gp = New ListViewGroup("total", "total")
ListView1.Groups.Add(gp)
Dim Item1 As New ListViewItem
Item1 = ListView1.Items.Add("total:", 0)
Item1.SubItems.Add("")
Item1.SubItems.Add("")
Item1.SubItems.Add("")
Item1.SubItems.Add("")
Item1.SubItems.Add("")
Item1.SubItems.Add("")
Item1.SubItems.Add(TotalSum)
Item1.SubItems.Add(TotalSum1)
Item1.Group = gp
ListView1.Update()
ListView1.EndUpdate()
