Hello,
I am knee deep converting our business app over to Telerik (which is an awesome suite of tools I wish I would have gotten it sooner!) and am running into an issue with the RadListView in detail view. I really need the ItemMouseHover event to work so I can show a custom form while the mouse is over the item but for some reason it's not firing. I have tested the ItemMouseEnter and ItemMouseLeave events and they fire correctly. Is there something I am missing to enable this event?
My test code is really simple:
Private Sub lvBusinessApps_ItemMouseHover(sender As Object, e As ListViewItemEventArgs) Handles lvBusinessApps.ItemMouseHover
Debug.Print("Hover")
End Sub
Thank you

When RadListView is used in DetailsView, it uses cell elements, not visual item elements. That is why the ItemMouseHover wouldn't be fired. The possible solution that I can suggest is to subscribe to the RadListView.MouseHover event and detect what is the element under the mouse. If it is a cell element, perform the desired action, for example, show a form:
AddHandler Me.RadListView1.MouseHover, AddressOf RadListView1_MouseHover
Private Sub RadListView1_MouseHover(sender As Object, e As EventArgs)
Dim pt As Point = Me.RadListView1.PointToClient(MousePosition)
Dim hoveredCell As DetailListViewCellElement = TryCast(Me.RadListView1.ElementTree.GetElementAtPoint(pt), DetailListViewCellElement)
If hoveredCell IsNot Nothing Then
Dim form As New RadForm()
form.Text = hoveredCell.Text
form.Show()
End If
End SubOff topic, since you mentioned that you are converting your business app, please have in mind that Telerik UI for WinForms offers a WinForms Converter. This tool allows you to convert the standard .NET Windows Forms controls for all projects in a particular solution to their equivalent in Telerik UI for WinForms. It aims to speed up the conversion process and save time when such projects are modernized.
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
