I use a listview to display an image in a row and a description in another row. I'm trying to change the height of a smaller description but not work.

  
Private Sub RadListView1_VisualItemFormatting(sender As Object, e As ListViewVisualItemEventArgs) Handles RadListView1.VisualItemFormatting
    e.VisualItem.ImageLayout = ImageLayout.Stretch
 
    If Convert.ToInt32(e.VisualItem.Tag) / 2 = 0 Then 'images
        e.VisualItem.BackColor = Color.Azure
        e.VisualItem.Size = New Size(950, 259)
    Else 'descripcion of image
        e.VisualItem.BackColor = Color.Black
        e.VisualItem.Font = New Font("Consolas", 20, FontStyle.Bold)
        e.VisualItem.Size = New Size(950, 50)
    End If
 
End Sub

Hi Manuel,

Thank you for writing.

Due to the virtualization in RadPageView visual items are being only created when needed and reused later on. In order to properly be able to mark certain items, you could use the Taproperty of the data items:
e.VisualItem.Data.Tag

Depending on where you are setting the tag, the way to set it would vary. For example, here is how to set it when creating an item:
Dim dataItem As New ListViewDataItem()
dataItem.Tag = 2

I hope this helps.

Regards,
George
