How to: Use Custom Elements in the Linear Gauge Control

  • 2 minutes to read

This example illustrates how to add two buttons as custom elements to the linear scale and use them to increase or decrease the current scale value.

For this, create two ScaleCustomElement objects and add a button control to each custom element.

Finally, to provide the capability for end-users to change the scale’s value, handle the button1_Click and button2_Click events and write code that will increment and decrement the scale value.

View Example

<Window x:Class="LinearGauge_CustomElement.MainWindow"
        Title="MainWindow" Height="450" Width="325">
        <dxga:LinearGaugeControl Name="linearGaugeControl1" Width="170" >
                <dxga:LinearScale >
                        <dxga:ScaleCustomElement VerticalAlignment="Top" HorizontalAlignment="Right">
                            <Button Name="button1" Content="Up" Width="40"  Click="button1_Click" />
                        <dxga:ScaleCustomElement VerticalAlignment="Bottom" HorizontalAlignment="Right">
                            <Button Name="button2" Content="Down" Width="40" Click="button2_Click" />
                    <dxga:LinearScale.LevelBars >
                        <dxga:LinearScaleLevelBar x:Name="bar"  Value="50" />
                    </dxga:LinearScale.LevelBars >
                        <dxga:LinearScaleLayer />
                <dxga:LinearCleanWhiteModel />
