How can I count the number of items in the listview.
Example scenario.
Today, I added students say, 20 students and tomorrow I added another 15 students, i need to have a breakdown on how many students i have been adding per day.
i have a listview box full of items, image below:
when i click a button i would like a msgbox to pop up displaying how many are alive.
How would i do this ?
Also how would i remove all items that status is "Dead"
I have a project where I am using a listview to display a data received through XML. One of the columns called "STATUS" display only 2 text data, either "ON" or "OFF". I would like to know how to count how many times the word "ON" it is apearing in that column and same for the word "OFF". I am using this code to count how many lines I have in the listview Label1.Text = ListView1.Items.Count() but I couldn't figure out so far how to count of the words "ON" or "OFF" in the column "STATUS" wchich have the index 9.
View 4 RepliesI have a listview that I add items to by loading from a file, and that works fine. I then edit the items or add new ones, and on form dispose, the file is supposed to be saved containing the listview items, but when I step through this process, mylistview.items.count is said to be zero, which I know is not true because I can see the items right on my screen, I added them myself.[code]I use this same method for saving and loading to and from listboxes, and it works fine.
View 3 RepliesI'm making an app on wpf.Basically, I have a list view with 6 columns,For each item of the listview, its details are displayed are displayed in each of the columns, except the first.Basically I want the listview to automatically display a count of the items for the 1st column.[code]I have sorting and other weird stuff happening in the app, and I want to keep the first column constant. All that is needed from the column is that it counts the items.[code]I just realised this isn't vb .net so to speak.I code only on vb .net, but having trouble with that xaml bit atm. Would rather not use vb codes for solving this particular matter if possible

View 3 RepliesOn to my question.I have a List(of String) that contains multiple items in each index.
A list declared as:
Dim NewStrings As New List(Of String)
May contain the following:
item (0) - (1 MKNO ABC 2.45 STND 3.3)
item (1) - (1 MKGO ABC 1.34 STND 2.5)
item (2) - (1 MKNO ABC 2.45 STND 3.3)
item (3) - (1 MKNO ABC 2.45 STND 3.3)

Here is the current code I am using to add files and check the number of lines in each file that was selected (file qty). This is also added into a seperate listbox for viewing.
Dim selectedItems = (From i In ListBox2.Items).ToArray()
For Each selectedItem In selectedItems
ListBox1.Items.Add(selectedItem)
[code].....
I don't know what is wrong with this code, but it is not detecting when there are no items in the listbox. It ALWAYS returns that there is something in the listbox, even when there is not and keeps erroring on the line of code in BOLD.[code]
