How to Get Value from Selected Item in Listview

Submitted by admin on Tuesday, April 21, 2009 - 12:06.

I am struggling before on how to get value from selected item in a listview. As you've seen in my Hotel Reservation System (VB.NET Version) I use the following code to get the value from a Listview.

Dim FolioNumber As String
For Each sItem As ListViewItem In lvList.SelectedItems
     FolioNumber = sItem.Text
Next

Although it is working fine but the succeding code will generate an error in the IDE of VB.NET.

        With frmCheckIn
            .State = modGlobal.FormState.adStatePopupMode
            .FolioNumber = FolioNumber '< = Variable "FolioNumber" is used before it has been assigned a value. A null reference exception could result at runtime.
 
            .ShowDialog()
 
            Call FillList()
        End With

After searching the internet I found a good solution to this problem. Just change the code above with this code:

.FolioNumber = lvList.SelectedItems(0).Text
