    Hey Community,

    I create a list with the UltimateListView and fill the list with my layout, on this layout are 3 Buttons and any labels.

    Here a small section:

    How can i give the first label +1 when i press the smylie? the Smylie is an Button.

    I've tried it, but do not come any further:

    Sub ulv_ItemClick(ItemID As Long, Position As Int, ClickedPanel As Panel)
       Dim pnl_main As Panel = ClickedPanel.GetView(0)
    Dim btn_up As Button = pnl_main.GetView(6)
    Dim lbl_counter As Label = pnl_main.GetView(5)
    'if counting = 1 Then
            'opo = lbl_counter.Text
            'ToastMessageShow(opo, True)
            'lbl_counter.Text = opo +1
            'counting = 0
        'End If
    '    counting = lbl_counter
    End Sub
    Thanks for help!

    Sub clv2_LayoutCreator(LayoutName As String, LayoutPanel As Panel)
    End Sub

    Sub clv2_ContentFiller(ItemID As Long, LayoutName As String, LayoutPanel As Panel, Position As Int)
    Dim Panel1 As Panel = LayoutPanel.GetView(0)
    Dim lbl_content As Label = Panel1.GetView(0)
        lbl_content.Text = 
    "Nur mit Seil und Haken gesichert auf einem schmalen Grat balancieren."

    Sub clv2_ItemClick(ItemID As Long, Position As Int, ClickedPanel As Panel)
    '    Log(ItemID)
        Dim pnl_main As Panel = ClickedPanel.GetView(0)
    Dim btn_up As Button = pnl_main.GetView(6)
        btn_up.Tag = btn_up
    ToastMessageShow(btn_up.Tag, True)
    Dim lbl_counter As Label = pnl_main.GetView(5)
    'btn_up.Tag = clv2.
    'ToastMessageShow(ItemID, True)

    'if counting = 1 Then
    '        opo = lbl_counter.Text
    '        ToastMessageShow(opo, True)
    '        lbl_counter.Text = opo +1
    '        counting = 0
        'End If
    '    counting = lbl_counter
    'ToastMessageShow( clv2.GetItemID(Position), True)
    End Sub

    Sub clv2_ItemSelectedStateChanged(ItemID As Long, Position As Int, Selected As Boolean)
    'Log("SelectionChanged ID=" & ItemID & ", Pos=" & Position & ", Selected=" & Selected)
    End Sub

    Sub btn_up_Click
    'Dim Index As String = Sender
    'Log("Index: " & Index)

    Dim b As Button = Sender
    ToastMessageShow(b, True)
    'Log("Button: " & b)
    'ToastMessageShow(counting, True)
    'Dim btn_up As Button = Sender
    'Dim ID As Int =  btn_up.Tag
    'ToastMessageShow(ID, True)

        counting = 
    End Sub
    End Sub
    I load a Layout from the designer, on this layout are the labels and buttons.

    If i press "btn_up" should on "lbl_counter" +1
    I have no idea, because I do not know how I get the ID of the button in the "btn_click" event to then change the label.

    To get the click event of a button, you just have to declare the _Click event sub as usual. To get the ID of the item in this sub, please read the documentation or look at examples.
