The only way I know how to put an item in a list view is to make a new item, which is the first column, then add a sub item for the columns after that and the item is placed in the row.For this Project I am wondering if there is a way to easily add items to individual cells, based on the column and group, not add items in a row at a time.
Something like the following image is what I need to do with code. To get this I manually added the items in the designer. But the logic bases where to put the class on the other classes in that time block (Mon at 8-1030am is one block). However if we have to add them a row at a time it throws off our logic and thought process.
How can I get items in listview? I know how to get the current item if selected but Im trying to put it in a loop where i need to get my three row items there.

For a = 0 To ListView1.Items.Count

I have a system which stores fee's paid for a youth teams players.A textfile stores:player name|trainingsessionsattended|amountpaidin..Each line is a new player's entry.I need to make a form that allows the user to input the amount paid by each player at the end of a training session.I did think of doing a single dropdown box and allowing the user to select a user and enter how much he/she paid and entering each players fee's one by one. But this is not practical, considering there are 20 players, this may take a while.I thought of having a listview with every players name and then using this to add the players fee's but am not entirely sure how to go about this.

I'm running it under a BGW and it works fine but is there anyone who can comment on it and make my code a bit better. I've a background worker and I am running it again and again on the RunWorkerCompleted like this
VB

BGW.RunWorkerAsync()
End Sub
Is it bad coding or is there any alternative to run it?
I need a control that will allow me to do a few things.
The control should be similar to Listview in detail mode, in that it lets me show numerous rows, each row with multiple columns. However, I want it editable in place... that is, the user can (if I let him) click on a column and change what is stored there.
The next thing I need to do is set a graphic in one column, text in another, a playback controller in a third, and a trackbar control in the fourth. Every row will look like that.
The final thing I need to do is be able to control how a row is painted... either the entire line or by putting a graphic image (like a button) in a column when it is not being edited.
Barring all of that, I can put all the controls I need into a single user control, then I need some listview-like control that will allow me to add that control to it.. and have it be operational.
I am writing a windows forms application in Visual Studio 10 on Windows 7.
I am facing little trouble while deleting the listview subitems. I am also using try and catch method to handle the execption but i am keep on getting it.

InvalidArgument = Value of '352' is not valid for index
Parameter name: index
Code is given below.
For i = 0 To lstListview.Items.Count - 1

lvi = lstListview.Items.Item(i)

If lviSubitem = "Error" Then

Ok, I found some code online on how to do this, but they only compare the Listview.item.text, and they don't care what is in the entire ListViewItem. Is there any code to remove duplicates in a ListView that checks to see if all the subitems are the same as well and THEN removes the entry? [Code]

OK, I've been searching for hours trying to find the best way to fill a listview from a comma delimited file but have come up empty handed so far. Currently I am using code I found on the NET, which works, but it is EXTREMELY slow. As a test, I created a file with 5,000 rows, and 10 columns. The column layout is as follows:123,NAME,NAME,NAME,NAME,0.00,NAME,YEAR,NAME,1

The code I am currently using appears to be loading the file and somewhat simultaneously filling the listview at the same time. I feel that I should load the entire file into an array or arraylist and the send the array or arraylist to the listview. However, if this is the best way to do it, I have not been able to find any examples of how to do this.

This is what VB.net did with the converting of the VB6 to .net
