Remarks

The CustomContextButtonToolTip event is designed to modify a context button’s tool-tip according to the value of the hovered point. 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.

C#

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;
        }
    }
}

VB.NET

Imports System

Private Sub tileControl1_CustomContextButtonToolTip(ByVal sender As Object, ByVal e As TileContextButtonToolTipEventArgs)
    If e.ContextItem.GetType().ToString() = "RatingContextItem" Then
        Dim rating As Integer = CInt((e.Value))
        Select Case rating
            Case 1
                e.Text = "Very Bad"
            Case 2
                e.Text = "Bad"
            Case 3
                e.Text = "Average"
            Case 4
                e.Text = "Good"
            Case 5
                e.Text = "Excellent"
            Case Else
                e.Text = String.Empty
        End Select
    End If
