I'm now trying a different approuch to my previous problem with the TreeView/ListView issue I had, this new "sollution" seems to be a bit more easy however I still can't solve it. The problem is to add the remaining listview.subitems, everything I try ether a: crashes app, or b: Only adds one subitem. If you take a look at the code you should see where my problem is.
Private Sub tvFolders1_AfterSelect(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles tvFolders1.AfterSelect
Dim id3folder As String
id3folder = e.Node.FullPath()

My concern, however, is that the subitems that are in the item.subitems collection are also a part of the main ListView.items collection.
There are very few examples out there for MS Chart and VS 2008 (the ones provided by MS are for a version different than what I have). What I am trying to do is get the value of the subitems in a listview (1 subitem is Subtotal and the other is Shipping) and put them on the chart. I don't know the best way to do this. I managed to get some code to work with a Datagridview but not with a listview. I have pasted the code for the chart with the datagridview below (to make the code run simply add MS Chart, a Datagridview and a button.Also, I posted a screen capture of a listview with the chart to give a better idea of what I am trying to accomplish.
Imports System.Windows.Forms.DataVisualization.Charting

View 3 RepliesI want to set a color on items and subitems being displayed within the listview control in a detailed view.Using the forecolor property setting would change the color of all the contents in the listview control. All I want is to display different colors on each column of the listview control. If I have four colums on the listview, it should display the contents on each column in a different color. I tried to do it on my own but it was unsuccessful. I'm looking for the exact code to set the color successfully. Currently, the code below is what I have to display the data on the listview. What line of code should I add on the code below to set different colors on items and subitems of the listview?

I'm trying to set a subitem in a listview to bold and a different fore colour. But it doesn't appear to be working, it's not throwing any errors either
lvServers.Items(i).SubItems(4).Font = New Font(lvServers.Items(i).SubItems(4).Font, FontStyle.Bold)
lvServers.Items(i).SubItems(4).ForeColor = Color.Yellow
If it makes any difference, the listview mode is set to "Details". I've also tried refreshing the listview and it makes no difference.In case it matters here is the partial block of code that snippet comes from:
For i = 0 To UBound(strWorldChunk) - 1
If IsNumeric(lvServers.Items(i).SubItems(4).Text) = True Then
If lvServers.Items(i).SubItems(4).Text = intFreeEmpty Then
