How can I get items in listview? I know how to get the current item if selected but I am trying to put it in a loop where I need to get my three row items there. I have 3 columns and I want to get there items and insert it in entry string.
This code is wrong
Dim a As Integer = 0
For a = 0 To ListView1.Items.Count
columname.Text = ListView1.FocusedItem.Text(a)
columntype.Text = ListView1.Items(a).SubItems(1).Text
columnscale.Text = ListView1.SelectedItems(a).SubItems(2).Text
entry = entry + columname.Text + " " + columntype.Text + "(" + columnscale.Text + ")" + vbNewLine + "" & _
""
Next
If I look at all the options for
me.ListView1.Items(index)
one of them is for Name.
So instead of coding
Me.ListView1.Items(index)
I can use
Me.ListView1.Items("Name")
But if I go into the properties of the ListView1 and look at the collection for the Items there is no place to set the Name.I can code Me.ListView1.Items(1).Name = "Name" and then I can code Me.ListView1.Items("Name")Where can you set the "Name" of the Items in a ListView?
Can someone help me about the following code? how can i get the sum total to the label.[code]

What is the best way to save listview items?
View 3 RepliesI have a ListView which might contains a lot of items, so it is virtualized and recycling items. It does not use sort. I need to refresh some value display, but when there are too many items, it is too slow to update everything, so I would like to refresh only the visible items.How could I get a list of all currently displayed items ? I tried to look into the ListView or in the ScrollViewer, but I still have no idea... the solution must NOT go throught all items to test if they can be seen, because this would be too slow.I'm not sure code or xaml would be usefull, it is just a Virtualized/Recycling ListView with its ItemSource bound to an Array.
View 2 RepliesI have a small application. When I click on a ListView row to Edit the details populated from the MS Access DB, I have the Else statement being executed all the time. Initially the code is attached behind a button named Edit. I have a Refresh button also which is clicked before the Edit button is clicked. Thus I just don't want to click on the OK button on the message box generated from the Else part. I just want to switch the Edit option between the ListView data when the ListView is item is clicked.[code]...

View 2 RepliesI have a listview with two columns of data in it. I want to capture all the items in the listview into an array. The array will have two dimensions, one for column 1 and the other dimension for column 2. I am a little lost on how to iterate over the listview items. I figure it would be a for each statement. Its also the actual call that passes the found item and sub item to the array I am struggling with.

I want to add images to listview and the code below should work in theory but it is not working. What should happen is when I select an Image from the openfiledialog it should then show in the listview box with the image plus it's filename underneath it. What happens is when I put 'Openfiledialog.showdialog' in the open button code underneath all the rest of the code and run my program.... it opens twice and only shows the file path but no image with it in the listview box. When I take that line out and press open..... it crashes and highlights any line with '(strFilename)' and says the error "not in legal form".
Here is the code for adding pictures to listview which is placed in the 'form_load' function
