Hi, All
I have ListView1 populated with one column (.NET 2003 version 1.1, SP3)
I need to populate second ListView2 with a few columns when user selects row
from ListView1.
I tried to extract the value of the selected row in
ListView_SelectedIndexChanged() event and ListView_ItemActivate(), but seems
it doesn't work.
What event fires when row selected in the ListView? Or how can i activate
event?
Please, advice
Thank you
 
You'll have to show us your code to show what "doesn't work".
SelectedIndexChanged occurs whenever the user selects a different item in
the list or removes a selection - you must check the SelectedIndices
property to make sure a selection was made. ItemActivate occurs when the
user first selects an item. If you tap an already selected item it won't
raise another event.

Hi, Peter
the following code doesn't work:

Private Sub ListView1_ItemActivate(ByVal sender As Object, ByVal e As
System.EventArgs) Handles ListView1.ItemActivate
MsgBox(ListView1.FocusedItem.Text)
End Sub

This one display message:

Private Sub ListView1_SelectedIndexChanged(ByVal sender As Object, ByVal e
As System.EventArgs) Handles ListView1.SelectedIndexChanged
Dim item As ListViewItem

For Each item In ListView1.Items
If item.Selected = True Then
ClickIndex = item.Index
MsgBox(ClickIndex.ToString)
Exit For
End If
Next
End Sub

Please, advice
Thank you
 
You don't need to loop through the collection to find the selected items -
use the SelectedIndices property. e.g.

If ListView1.SelectedIndices.Length > 0 Then
MessageBox.Show(ListView1.SelectedIndices(0).ToString)
End If

An item may be selected but not currently have the focus (indeed the focus
may be on another control).
