Hi,
I want to create a listview, which include in each row a button in the last column. To click on the button starts a handle (VB.NET), that should use the values of the other columns of the same row of the listview. To refer to this values I haves used SelectedItem, but I see this is not correct because the user can click on a button in a row that is not selected. Please what is the right property?
Thanks

Hello,
thank you for your answer. I've tried this:
strText = "Ebene 1 " & VisualTreeHelper.GetParent(sender).ToString & vbCrLf & _
"Ebene 2 " & VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(sender)).ToString & vbCrLf & _
"Ebene 3 " & VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(sender))).ToString & vbCrLf & _
"Ebene 4 " & VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(sender)))).ToString & vbCrLf

and get
Ebene 1 System.Windows.Controls.ContentPresenter
Ebene 2 System.Windows.Controls.GridViewRowPresenter Content:System.Data.DataRowView Columns.Count:7
Ebene 3 System.Windows.Controls.Border
Ebene 4 System.Windows.Controls.ListViewItem: System.Data.DataRowView

What would be the next step, please?

Best greetings
Peter

Hello,

now I solve the problem with your help:

So the VisualTreeHelper say me, the parent of the parent of my button is a System.Windows.Controls.GridViewRowPresenter I do this:

Dim myGrid As GridViewRowPresenter
Dim LstRow As DataRowView
myGrid = VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(sender))
Me.m_PlanRow = CType(myGrid.Content, DataRowView)
strText = LstRow("ANZAHL") & " " & LstRow("ERR_CODE")
...

Thanks
Peter :)

Hello,

You surely can get the sender of the event to get the button and use the VisualTreeHelper (http://msdn.microsoft.com/en-us/library/system.windows.media.visualtreehelper.aspx[^]) to get the clicked row.

Hope this helps you !
