ListView Questions

Posted on 2000-02-29

I am returning data from an AS400 database,

i.e. I click a node in a treeview and then the corresponding data is displayed (at the moment) in a ListBox.

I want to change this to output the data to a ListView, as I do not want the data displayed to be just text; I want to be able to click on the data that my treeview control has retrieved and perform furthur actions on it, (pretty much an emulation of Windows Explorer)

So far I cannot get my ListView to display any output

Can somebody provide with some code to:

i) Display the results of my nodeclick in a ListView, i.e. the nodeclick brings back data from a database, and I want to display it in a Listview.

ii) Code for how to manipulate data once it is in the ListView

Cheers,

Matt.

I am assuming that you had no problems displaying it in a list box, right?

In that case it's likely that you've just done something relatively basic wrong in your listview. If I'm mistaken, I'm sorry - didn't mean to be patronising....

Anyway, your list view's View property should be lvwReport

To add an item, check out the YourListView.ListItems.Add procedure

Make sure your list view has column headers.
use Yourlistview.ColumnHeaders.Add to add one


To set the text in a list item
ListItems(Index).Text = "Value"
This corresponds with the first column.

To set further columns, use the SubItems
SubItem(N) corresponds with column N+1

ListItems(Index).SubItems(1) = "hello"
ListItems(Index).SubItems(2) = "world"
etc.

You can't have more subitems than .ColumnHeaders.Count - 1

Er....

Also, check out the .SelectedItem property,


Some simple loops:

Dim objItem as ListItem

For lngCounter = 1 to YourListView.ListItems.Count
    Set objItem = YourListView.ListItems(lngCounter)
    With objItem
        .Text = "hello"
        .SubItems(1) = "World"
    End With
Next

to iterate through all items.

etc. etc. etc.

Does this help at all?
