ListView groups with totals and subtotals

ListView groups with totals and subtotals

(OP)
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.

RE: ListView groups with totals and subtotals


You can do this, but it will not be automatic. That is, you will have to calculate the subtotals and totals yourself and add them to the ListView.

For subtotals, you can either:
1) Enable footers for the groups and put the subtotals there. The drawback to this is that the columns won't align.
2) Add the subtotal to the group as the last item.

For the overall Total, you will need to add a group at the bottom of the ListView, name it Total and put the total there.

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()
