Example

This example demonstrates how to specify the width and height of digital gauge symbols in fixed and proportional values.

For this, it is necessary to create an instance of the SymbolLength structure with required values and then assign it to the SymbolViewBase.Height and SymbolViewBase.Width properties.

In this example, the symbol length can be set either in fixed or proportional values depending on which of the buttons has been clicked.

View Example: Set the Width and Height of Symbols in the Digital Gauge Control

MainWindow.xaml.cs

private void button1_Click(object sender, RoutedEventArgs e) {
    // Specify fixed values for symbol height and width.
    matrixView.Width = new SymbolLength(SymbolLengthType.Fixed, 44);
    matrixView.Height = new SymbolLength(SymbolLengthType.Fixed, 50);
}

private void button2_Click(object sender, RoutedEventArgs e) {
    // Specify proportional values for symbol height and width.
    matrixView.Width = new SymbolLength(SymbolLengthType.Proportional, 2);
    matrixView.Height = new SymbolLength(SymbolLengthType.Proportional, 5);
}

MainWindow.xaml.vb

Private Sub button1_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
    ' Specify fixed values for symbol height and width.
    matrixView.Width = New SymbolLength(SymbolLengthType.Fixed, 44)
    matrixView.Height = New SymbolLength(SymbolLengthType.Fixed, 50)
End Sub

Private Sub button2_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
    ' Specify proportional values for symbol height and width.
    matrixView.Width = New SymbolLength(SymbolLengthType.Proportional, 2)
    matrixView.Height = New SymbolLength(SymbolLengthType.Proportional, 5)
End Sub
