I have a listbox that calculates interest rates the code is as follows:-
dim amount as double = val(textbox2.text)
dim counter as integer
for counter = 1 to 10
listbox1.items.add(counter & " % " & formatcurrency((amount*counter)/100))
next counter
This works great but i would like to use a listview with two columns. 1 for the counter percentage .2 for the amount calculation.I have tried but am getting stuck with the subitems.

I have seen many examples of populating a listview from a datatable or converting a datatable to a listview but what I am trying to do is exactly the other way around.
How can I convert/copy the contents of a winform listview to a datatable?
[EDIT]
I have a listview with a context menu where users can multiselect items and choose one of the context menu options, I then loop the selected items and extract each selected row (listview item) and serialize it, instead of doing this I wanted to convert the listview to a datatable then add the datatable to a dataset and serialize the dataset.
I know that the "SelectedItems" in a ListView are a collection of items and therefore can not be converted staight away for instance into a string. How does one go about selecting just one of the items in the list view?My list view contains 3 columns/items: First, Last and EMPID. When the user selects a row in the listview, I need to pull out the EMPID item as a string variable.
View 6 Repliesi have never created one and the manual is to difficult to understansi want to create a listview as shown belowhow do i go about doing this,using laymans terms.I dragged a listview control onto the form, but then im stuck. how do you add columns (which are actually displayed on the control), i have added columns in the properties but they cant be seen in the listview.
View 6 RepliesI have a relatively simple Listview that suddenly needs (due to new requirements) to have it's 'layout' extracted to a DataTable so that a common routine can convert it to an Excel spreadsheet for export purposes.The ItemTemplate is just a series of Table Rows with some text, data-bound labels and textboxes with validators in the cells.Usually, when trying to pull out a particular value (like what was entered into a text box), I use the ListViewItem's .FindControl method.
For Each objItem As ListViewItem In lvwOptions.Items
Dim objTextHrsLabor As TextBox = CType(objItem.FindControl("txtHrsOptByLabor"), TextBox)
decHours = CDec(objTextHrsLabor.Text)
Next
In this case, however, I'm trying to take all the data displayed - all the 'rows and columns' of the table that was created.Inside the ForEach / Next loop of ListViewItems, I started a ForEach/Next loop of Controls for each instance's controls but I got some really strange results returned (like controls that had a couple of table cells in them).
I get the sense I'm headed in the wrong direction. All I want is for the nicely-formatted 5-line, 6 column table to be converted to a 5-line, 6-column data table.

View 1 RepliesI've start on another program and I'm confused whether to use a listbox or listview to display output. I have 2 books but neither mention the use of Listviews and they don't cover using Listboxes for displaying output, and will be used in combination with combo boxes as this is how the user will enter the information. I know I want to use a global variable to total scores if this makes any difference at all.

Heres the code:

I have a listview with checkboxes on the left side and 2 columns of data. What I want to do is populate a listbox when the user checks a row in the listview. I've tried code in the Item_Check event. It does not pick up the item checked. It's as though it's behind. For example if my listview has a list of country codes and I check US, the code returns nothing but if I check another item, it picks up US. Same thing happens in the SelectedIndexChanged event. If I use a button, all works as expected.
