vb.net - backgroundworker & listview.items.add()
I'm using a vb.net backgroundworker thread for processing and I need to periodically add items to a listview (with multiple columns) during the thread processing.
I can easily use the following code for delegating the task to add an item to a listview, but I can't figure out how to additional info to other columns on the same row.
Anyone help me?
In the thread, I'd execute the following to trigger the invoke to add to listview:
AddListItem(ListView1, filepath)
Here is the delegate code, if someone can show me how to add the text2 to a 2nd column I'd appreciate it HUGE:
Delegate Sub AddListItem_Delegate(ByVal [Label] As ListView, ByVal [text] As String)
Private Sub AddListItem(ByVal [ListView] As List开发者_运维知识库View, ByVal [text] As String, Optional ByVal [text2] As String = "")
If [ListView].InvokeRequired Then
Dim MyDelegate As New AddListItem_Delegate(AddressOf AddListItem)
Me.Invoke(MyDelegate, New Object() {[ListView], [text]})
Else
ListView1.Items.Add([text])
End If
End Sub
Create ListViewItem
s explicitly as shown here with all necessary subitems and use ListViewItemCollection.Add
overload that accepts ListViewItem
as arguments.
