Dim index As Integer = LV.SelectedIndices(0) But unfortunately "selectedindices" is not a member of the stratalistview. Thanks a lot and Merry Christmas for all of you Thomas

Here is a sample code of how I populate one of my StrataListView with a checkbox column: For Each bo As bizTransactionItems In .BusinessObject.GetEnumerable() '-- Create a new item. The item is actually the first column as well. ' The first column will have an icon and a checkbox item = New StrataListViewItem(String.Empty, String.Empty, MicroFour.StrataFrame.UI.Rendering.Enums.StrataCheckBoxSupportType.TwoState, MicroFour.StrataFrame.UI.Rendering.Enums.StrataCheckedState.Unchecked) '-- Create the sub items. A sub-item is ultimately nothing more than a column. item.SubItems.Add(bo.cfp_CardDescription, String.Empty) item.SubItems.Add(Format(bo.ItemQty, "n0"), String.Empty) item.SubItems.Add(bo.CardStartSerialNumber.ToString, String.Empty) Dim groupTitle As String = String.Format("Reference #: {0} Processed by {1} on {2}", bo.CurrentRow.Item("ReferenceNo"), bo.CurrentRow.Item("ReceivedBy"), bo.CurrentRow.Item("ReceivedOn")) item.Group = .Groups(groupTitle, True, False) '-- Create a custom data item that stores the primary key of this record item.CustomData.Add("PrimaryKey", bo.PK_TransactionItems) '-- Add the item to the list Me.lstCSVActivationExport.Items.Add(item) Next Notice how I create a CustomData item named "PrimaryKey" and store the business object primary key value. Then to read it use something like this: If Me.lstCSVActivationExport.SelectedItems.Count > 0 Then '-- Attempt to navigate to the selected record in the list view. Me.bizCSVActivationExport.NavigateToPrimaryKey(Me.lstCSVActivationExport.SelectedItems(0).CustomData("PrimaryKey")) End If It has been a while, but I posted a message on 9/21/2010 with some enhancements I did to a subclass of the StrataListView that could be useful to you. Today I am using DevExpress grids for 99% of my list needs, but the SF StrataListView is very powerful and fast. Here is the link for that post: http://forum.strataframe.net/FindPost28459.aspx Also search the forums for "StrataListView" for great posts that will also help you out. Good luck!!!! Edhy Rijo

I get bibliographical data through a Rest-API, assign it to an objects, than save These objects in a List of Objects, which populate the listview. Works all fine but I want to move and remove and add objects so I need the index. But I found an easier way: LV.Items.RemoveAt(LV.Items.IndexOf(LV.SelectedItems(0))) By now, this seems to work. Best regards Thomas
