Forms :: Listview Itemactivate Stops Working?
Dec 23, 2009I have two forms frmA, frmB. I have a listview on frmA with a couple items with tags. In the listviews Itemactivate event I get the FocusedItem's tag and open frmB. Everything works fine until I close frmB and come back to frmA. The original item is still selected but the Itemactivate no longer opens frmB. I can step right into the frmB.Show line on frmA, it's just that frmB nevers shows.
Private Sub ListView1_ItemActivate(...) Handles ListView1.ItemActivate
Select Case ListView1.FocusedItem.Tag
Case "showfrmB"

VS 2010 Add Items To ListView Not By Row?
Oct 24, 2011The 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.

VS 2010 Listview And Checkbox's
Dec 19, 2011I 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.

VS 2010 - Editable Listview Control ?
Jun 16, 2011I 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.

VS 2010 : Cannot Get ListView Items To Show
Oct 29, 2011I've used the same method to add items to a listview before but for some reason they're not showing, I even just tried a test:
Dim row As New ListViewItem
row.Text = "test"
row.SubItems.Add("test")
lstvwHistory.Items.Add(row)
in the load and that doesn't show up.Here is what I am trying:
gameDate = HistoryDS.Tables(0).Rows(0).Item("gameDate")
frmGameHistory.NewGroup(gameDate.ToShortDateString)
For Each row As DataRow In HistoryDS.Tables(0).Rows
[code]....
I walked through the code having a message box pop up every time an item was added with the count and it goes up as it should, nothing throws an error, and the item has all the correct parameters. I commented out the making a new group and just plain add the items and it still didn't show. I tried the lstView in all the kinds of views (detail, small icon, etc.)

VS 2010 Faster Way To Load A Listview In .NET?
Nov 4, 2010OK, 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
Dim ofd As New StreamReader(".dataCardData.bct")
Try
Using reader As New Microsoft.VisualBasic.FileIO.TextFieldParser(".dataCardData.bct")
reader.TextFieldType = FileIO.FieldType.Delimited
reader.SetDelimiters(",")
[Code]...
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.
