Hi Piro,

To attach tooltips to the XAxis items you should register for the RadChart BeforeLayout event. Here is a sample code:
RadChart1.BeforeLayout += new EventHandler<EventArgs>(RadChart1_BeforeLayout); 
    void RadChart1_BeforeLayout(object sender, EventArgs e) 
    { 
        foreach (var item in RadChart1.PlotArea.XAxis.Items) 
        { 
            item.ActiveRegion.Tooltip = "Item " + RadChart1.PlotArea.XAxis.Items.IndexOf(item); 
        } 
    } 

Hope this helps!
