A TileView can display context buttons for each tile (see the TileView.ContextButtons property description to learn more). The CustomContextButtonToolTip event allows you to customize a tooltip for each context button. Primarily, this applies to RatingContextButtons and TrackBarContextButtons. The following code sample illustrates how to assign a different tool-tip for each of the 5 rating button grades.

void tileControl1_CustomContextButtonToolTip(object sender, TileContextButtonToolTipEventArgs e) {
    if(e.ContextItem.GetType().ToString() == "RatingContextItem") {
        int rating = (int)e.Value;
        switch(rating) {
            case 1: e.Text = "Very Bad"; break;
            case 2: e.Text = "Bad"; break;
            case 3: e.Text = "Average"; break;
            case 4: e.Text = "Good"; break;
            case 5: e.Text = "Excellent"; break;
            default: e.Text = String.Empty; break;
