I 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.
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 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.
I'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
I have a ListView with the columns 'Name', 'Expected', 'Total', and I want to add another column saying 'Recount' at the end. The 'Recount' column will ideally have a checkbox only if the 'Expected' value is larger than the 'Total' value.
So far I have got the ListView with columns and can add a check box on the left hand side, but that check box is not under a column heading (though I can probably put another column with no values in there to work around that) and it is on all of the records.
i made a media player program and i am having many problems! the main issue is that i have a listview that displays music playlist, how can i get it to navigate to the next item after the clicked one is over that way users don't have to click on the next one to continue their playlist?
How can I save ALL of the items in a listview, items that were added by the user? I tried application Settings and tried creating a settings file but there is not a settings option for listview items.
in a list box which is populated by the end user using this code
Dim lb1s As String = Form1.Folder.SelectedPath Dim di As New IO.DirectoryInfo(lb1s) Dim mydirInfoArray As IO.DirectoryInfo() = di.GetDirectories
[code]....
I have 3 text boxes i want to display the number of items in the list box which contain certain words,So for example in textbox1 i want it to display the total number of items in the list box which contain "(U) or [u] or [ntsc-u]" etc, this will be triggered via page load or a button which ever works best.
Im trying to print out all the items/sub items of a listview into one string.
here is the code i have:
For Each lvwItem In ListView1.Items ' Print the subitems of this particular ListViewItem For Each lvwSubItem In lvwItem.SubItems
[Code]....
How do i just print out the value (MyItem1) without the "ListViewSubItem: {}" part? I know i can use a string function to remove this, but id rather not
I have a listbox which gets populated by listing ftp directories, and when i list them, i have all items in listboxnow, i want toremove items that have extension different than .png .gif .bmp .jpg (or other image fromats)basically, i need to remove items that do not contain one of theese extensions in their name
If tbquantity.Text = "" Or tbdescription.Text = "" Or tbprice.Text = "" Or tbproductcode.Text = "" Then MessageBox.Show("Please Select Items", "Empty", MessageBoxButtons.OK) Else If lvadd.Items.Count = 0 Then lv = New ListViewItem(tbproductcode.Text) lv.SubItems.Add(tbdescription.Text)
I have a List object and I want to remove the duplicated items but leaving at least one of the duplicated items in the list;I wrote something like this however I would optimize this code for better performance, is there something faster?
Const chars As String = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz" Dim rnd As New Random() Dim mylist As List(Of String) = Enumerable.Range(1, 100).Select(Function(i)
[COLUMNHEADER1] [COLUMNHEADER2] [COLUMNHEADER3] [CHECKBOX] Graham [CHECKBOX] Greg [CHECKBOX] David
What i was trying to do is put text in [COLUMNHEADER3] besides each of the names, so if "Graham's" details exist then put "PASSED" beside the name "Graham" and "FAILED" if it's failed, i'm not sure how to access the 3rd columns details to put that in is it:
ok in vb6 i would use this to check all items in a listview.
[Code]...
Now Here's my confusion. And i spotted at least one other person on here who was asking the same thing about this.But got no real clear answer that i could see. as a test to compare i tried his suggestion and loaded the same listview up in both a vb6 app and a vb.net app..The list i used was quit large so the comparison would be very through..my list was in the 80,000 lines range tho..yeah talk about overkill The vb6 app checked/unchecked the items within a matter of milliseconds..the vb.net took an extremely long time tho..well not extreme but was very noticeably slower about doing the loops.
I have a listview with 5 columns want when i click a button to merge some items into each other, like this:
I have 20 items in it. When i click the button it should look after items with the same text in the 2 column.Say it found 3 items that has the same text in the 2 column. Then it should the integers from the 3 column and add to each other.
VB.Net Public Sub LoadXML(ByVal file As String, ByVal ListViewName As ListView) Dim XMLfile As New XmlTextReader(file)
[Code].....
However, no errors are shown, the items are not added to the ListView. Also, if i check the values of "artist", it is populated, as are the rest. It just, for some reason, does not add to a listview on another form.
I'm a student and I have a small project to create for my VB class. For the personal touch, I tried using a ListView to manage a SQL database (on a remote web server).What I need to do right now is determine how many items are selected (if more than one, enable delete and edit buttons, if more than one, disable edit button). I searched a lot for that, but didn't find anything working with me.Do you know a simple way I could get the number of items that are selected in my ListView?
I have the following linq statement to go through a dropdown menu's sub items and get what items are checked: vb Dim UnselectedItems = From xItem As ToolStripMenuItem In tsiSelectObjects.DropDownItems Where TypeOf xItem Is ToolStripMenuItem AndAlso CType(xItem, ToolStripMenuItem).Checked = False
I get this error tho: Unable to cast object of type 'System.Windows.Forms.ToolStripSeparator' to type 'System.Windows.Forms.ToolStripMenuItem'. As you can probably guess i have ToolStripMenuItems and separators in there
However the AndAlso should short circuit in the case where the item is not a ToolStripMenuItem and it doesn't seem to be doing so (as TypeOf xItem Is ToolStripMenuItem=false in this case)?
I am currently using VB 2008 and there is a form I'm using which contains a listview control. I am dynamically filling the listview with groups and items. After I fill it up, it is supposed to look like this:
[CODE]...
Each item is specific for each group. The problem I have is that when I maximize the form to full size, and everything expands, the items change positions into something like this:
[CODE]...
How can I make the listview keep the items in the "row" view always, instead of the "column" view whether I maximize or not?
