ListView - Show Each Item In Separate Row / Add Subitems?
Aug 4, 2010
This is the first time I have used a list view control since vb 6, and I have some basic questions.
1) How do I get the listview to show each item in a seperate row?
2) How do I add sub items to the listview?
Below is the code of the function I am working on to populate the listview. Right now it shows my entry in columns and I dont know how to display the sub items.
Private Sub loadListView()
Dim str As String
Dim SQLString As String
Dim k As Integer
str = ""
[Code] .....
I have 1 table which has columns which include "parent" which says who the parent is if there is a parent, and "name" which has the name of the item. so for example
[Code]...
or something to that affect. the reason being that the user can do the autocomplete by typing a letter or a few letters, it will go to the parent and then they can use the enter key to move down 6 or so down at a time( if possible) or arrow to move 1 at a time down.
Is this possible in DGV or should I go use something else? I have seen this used in a program before but I do not know how it was implemented.
I am trying to save a listview item and 5 subitems to a txt file, I have tried one solution that was posted on here but i could not manipulate the code for all of my sub items.
I am trying to programmatically select all items, including subitems, in a listview and can't seem to get the result I am looking for. I have FullRowSelect = True set and when I click on the items, all is fine. However, if I use the following code, only the ListViewItem is selected and not the item's subitems. Is there a way to achieve this?
i'd like to find/filter listvew item as i type in a textbox, the listviewitemfind doesn't seem to work whe i try it.is this possible without looping through all columns and then all rows?
I am listing folders and folder sizes in a ListView for a VB.NET WinForm program I'm writing. I would like to total the folder sizes in the last entry of the ListView and 'lock' it show it always shows (even if scrolling through the list. Is there a way to do this? I'd really like to avoid adding another control on the Windows Form to display the total.
EDIT:Space is somewhat of an issue as I'm trying to keep this window small enough to work in a min screen resolution of 800x600 (I know, not the standard, but I want to make this available to even those in the elderly community with problematic eyesight.

Private Sub tvFolders1_AfterSelect(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles tvFolders1.AfterSelect Dim id3folder As String
[CODE]...
I'm now trying a different approuch to my previous problem with the TreeView/ListView issue I had, this new "sollution" seems to be a bit more easy however I still can't solve it. The problem is to add the remaining listview.subitems, everything I try ether a: crashes app, or b: Only adds one subitem. If you take a look at the code you should see where my problem is.
Private Sub tvFolders1_AfterSelect(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles tvFolders1.AfterSelect Dim id3folder As String id3folder = e.Node.FullPath()
I'm trying to find out how to Edit/add/read individual subitems in a populated Listview box I seem to be going round and round in circles looking on the "net"
I was attempting to follow a few tutorials for the ListView control. I am able in the designer to add items and subitems but I want to be able to add them in at runtime. I can do ListView1.Items.Add quite fine but when I attemp to input ListView1.SubItems (As the tutorial suggests) I get an error that is: Code: 'SubItems' is not a member of 'System.Windows.Forms.ListView' I am using Visual Basic.NET 2008 Express.
saving a listview with its subitems. I have 2 buttons when one is clicked it loads listview items and then when I click the other button it clears the listview and loads more listview items. My question is how do I save a listview before the listview is cleared and also loading a saved listview?
I am trying to chnage a listviews subitem forecolor but it not seem to be working I can set the text color of the first item but not the second here my code.
vbnet Dim Litem As ListViewItem Litem = New ListViewItem()
I have run into an issue and need help solving it. I know how to go about adding items to My.Settings and I have already created the Specialized String Collection to My.Settings called List but I am having some trouble getting the items and the subitems to save to the list.
I have the following scenario. I need to take a listview that is in details mode and output the data to a tab-delimited file. I've always been perplexed as to how listviewitems and subitems relate to each other. I have the following
For Each Item As Windows.Forms.ListViewItem In ListView.Items For Each subitem As Windows.Forms.ListViewItem In Item.SubItems Next Next
My concern, however, is that the subitems that are in the item.subitems collection are also a part of the main ListView.items collection.
There are very few examples out there for MS Chart and VS 2008 (the ones provided by MS are for a version different than what I have). What I am trying to do is get the value of the subitems in a listview (1 subitem is Subtotal and the other is Shipping) and put them on the chart. I don't know the best way to do this. I managed to get some code to work with a Datagridview but not with a listview. I have pasted the code for the chart with the datagridview below (to make the code run simply add MS Chart, a Datagridview and a button.Also, I posted a screen capture of a listview with the chart to give a better idea of what I am trying to accomplish.
Imports System.Windows.Forms.DataVisualization.Charting Imports System.Globalization Public Class FrmChartTest
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.
The error which I am getting is: InvalidArgument = Value of '352' is not valid for index Parameter name: index
Code is given below. For i = 0 To lstListview.Items.Count - 1 Try lvi = lstListview.Items.Item(i) lviSubitem = lvi.SubItems.Item(3).Text If lviSubitem = "Error" Then lvi.Remove() [Code] .....
I have a multiline textbox in which i add values to.A button is pressed to put these values in a listview in the first column.I then have 5 or 6 other comboboxes and textboxes that will send information as subitems to the listview, only if the original item in the listview has a checked box. The code i currently have is just adding the subitems to however many checkboxes are checked.I am trying to get the subitems to add to all of the items that have checked boxes rather than creating there own rown underneath the checked boxes.[code]
i have an listview containing an normal listviewitem plus one subitem What i want to do is save the info in the listview in a textfile and load when i start my program. So that all the info will be saved, but how do i do this?
