I feel like I must be missing something obvious.I have a listview with 6 columns. The first, hidden, is a key value. The other five are FirstName, MI, LastName, Gender, and CurrentGrade.When I go to populate the listview, I pull a datatable and do this:
For Each dr As DataRow In dt.Rows
Dim lvi As New ListViewItem(dr("StudentKey").ToString)
For i As Integer = 1 To 4

But when the form loads, I get the MI in the FirstName column, the First Name in the LastName column, the LastName in the Gender column, and the Gender in the CurrentGrade column. The MI is blank. I've run it in debug, and the correct values are in the correct subitems. But for some reason, when the ListViewItem is added to the ListView, the subitems get all jumbled.

Can someone help me with this code? I just need to make it so there is no limitation on how much data is loaded in the columns or rows, it populates very nicely for smaller comma delimited files , but if I try to load something that goes for example over to AV column, it errors out.I don't care about VIEWING this data, I am just trying to get it into a LISTVIEW so I can access the data for other methods in my code.Index was outside the bounds of the array.

I have started the familiarize myself with WPF and have gotten stuck with the ListView I've read a lot of documentation about binding and I can't seem to find how to populate a ListView programmatically. It seems like a lot of work to create the binding and classes, etc, just to fill a ListView.
1. If you want to populate a ListView with data that a user has inputted, is the correct way in WPF to populate the ListView with binded data?
2. How do you add items and subitems to a ListView in code? (There doesn't seem to be a subitems in WPF.)

View 2 RepliesI'm trying to dynamically create a listview. on reports.aspx user selects a bunch of checkboxes. On the next page, user sees reports.aspx, and should see a table with columns of the checkboxes he selected. My idea was to create a listview, then dynamically change the header row of the LayoutTemplate, then change the select statement depending on which columns selected. This is what I have:
<asp:ListView runat="server" ID="ReportListView" DataSourceID="ReportListViewSDS">
<LayoutTemplate runat="server">
<table runat="server">

Problem is that this doesn't work because i can't put a code block (<%%>) inside the LayoutTemplate. Is there a way in the code behind to edit the LayoutTemplate, or another way to cycle through the Request.Form vars and build the table header row with it?

View 1 RepliesMy main goal is to have an excel spreadsheet that automatically plots the overall success of my stock portfolio over time (% change over time). I've been able to incorporate stock data into my spreadsheet by linking it to the web, but the trouble is the spreadsheet will keep no history of what the previous stock values were, so I can't graph how things change over time. This sounds like it might be too complicated to be built in to excel, so I was wondering if anyone knew how to program this in Visual Basic. Maybe something like this.... If refresh then new cell plus new time stamp. Another possibility would be to have a whole bunch of cells that refresh only once but at longer and longer intervals, e.g.,

I have a combo box bound to a datasource. I need to change one combo box (of many) to order the items in descending order.I'm guessing I could order the collection in the dataset, but that will mean all my combo boxes will be reordered?

But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.
