I have 5 columns and the rows are not dependent on each other. I just want to add items to each column. How can I do this? For example, I want to do:
listview1.column(0).add("add something to column 1")
listview1.column(1).add("add something to column 2")
etc
But it's not letting me do this?
I have a listview control that I have a multitude of files displayed, in addition there are 6 columns in the listview that shows information about the file in question.
I have gotten this far, but my question is this: how do I allow the user to sort the listview by clicking on the column headers. Like one can do in list view in a Windows window?
im trying to make the listview sort the listview items by column (whichever column was clicked, sort the list based on that column)
in vb6 it was done by:
Private Sub ListView1_ColumnClick(ByVal ColumnHeader As MSComctlLib.ColumnHeader)

View 4 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 1 RepliesI want to set a color on items and subitems being displayed within the listview control in a detailed view.Using the forecolor property setting would change the color of all the contents in the listview control. All I want is to display different colors on each column of the listview control. If I have four colums on the listview, it should display the contents on each column in a different color. I tried to do it on my own but it was unsuccessful. I'm looking for the exact code to set the color successfully. Currently, the code below is what I have to display the data on the listview. What line of code should I add on the code below to set different colors on items and subitems of the listview?

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 am very new to Visual Basic, and I need to add items from my database to the ListView control. I have a table in the database called tblChannels that I would like to draw the information from and populate the ListView control in VB, in the form of a column. I currently am unsure about how to go about doing this. Previously I have created combo boxes that draw the information from the database, but trying this method for the ListView does not work how I want it to.
View 5 RepliesI have added three columns to the ListView control,
listView1.Columns.Add("id", listView1.Width / 3); listView1.Columns.Add("Name", listView1.Width / 3); listView1.Columns.Add("Address", listView1.Width / 3);
Assume the ListView1.Width is "30", then each column should be in event width of 10. Furthermore thereshould only be three columns becuase i have added only three columns. However, when i resize teh form, the listview controls shows an additional column.
How this was added? How do i fix this, so that when i add 3 columns it will have only three columns even when resized the form or not
I've attached a picture of the list view control that I am using. I've been fine until now, I want to save the entire line of items in the list view control (item_description, price) and dump it into the MySQL database to allow tracking of reciepts. The following code that I have saves the first column worth of information, but I cant figure out a way to save the second column (the price)
Dim li As ListViewItem
For Each li In ListView1.Items
CurItems = CurItems.ToString + li.Text + ", "

Oh right, and I'm making it comma seperated values so I can pull it up in a readable format again.

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.

Dim a As Integer = 0
For a = 0 To ListView1.Items.Count
columname.Text = ListView1.FocusedItem.Text(a)

I have a list view control and for each item I set to display an icon it will change the icons for the other items that already have icons, to the most recently added icon.
Here is my code.

Dim fileandparam As String = IconsInfo(ext).ToString

I'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

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.)
I have a listview in details mode with multiple columns. I want to be able to temporarily hide entries. I know the old Listview.Items(x).hide = true doesn't exist (from research).I'm wondering if there's a way to create a temporary list of every item NOT to display, remove them from the listview, then when I want them back, just re add them from the list

I'm gonna add x number of items to a listbox in form #2 form form #1. When I click the button it opens Form #2 and then I tried this code (which makes the form freeze):
Dim qwe As Integer = 1
Do Until qwe = regKey.GetValue("Count") + 1
PrMaker.ListView1.Items.Add(regKey.GetValue(qwe))
qwe = qwe + 1
Loop
The regKey.GetValue("Count") is a registry key which contains a integer (unknown). What is wrong, or is there another, better way, of doing this?
