[Solved] Gauge control customization help

[Madhan]

Hi Team,

This is Madhan and I am building sample Windows 8 Store Application using Xaml and C#.I would like to change Gauge the control parameters dynamically through the code behind file.

for example I would like to change the BarIndicatorSegment Length value dynamically through the code behind file how can I apply these changes. Please help me.

I tried like this rdscrngMtd1Revenue.Length=70 and also ndlBusiness.Value=80 but it is not working.

<telerikDataViz:RadRadialGauge x:Name="rdscMTDRevenue" Width="140" Height="200" MinValue="0" MaxValue="100" LabelStep="10" Margin="0 40 0 0" TickStep="10" telerikDataViz:RadRadialGauge.MinAngle="-30" telerikDataViz:RadRadialGauge.MaxAngle="210" LabelRadiusScale="1.10">

<telerikDataViz:SegmentedRadialGaugeIndicator x:Name="rdscMTDRevenueTemp" StartValue="0" Value="100">

<telerikDataViz:BarIndicatorSegment Thickness="2" x:Name="rdscrngMtd1Revenue" Stroke="Red" Length="40"/>

<telerikDataViz:BarIndicatorSegment Thickness="2" x:Name="rdscrngMtd2Revenue" Stroke="Yellow" Length="30"/>

<telerikDataViz:BarIndicatorSegment Thickness="2" x:Name="rdscrngMtd3Revenue" Stroke="Green" Length="20"/>

</telerikDataViz:SegmentedRadialGaugeIndicator>

<telerikDataViz:ArrowGaugeIndicator x:Name="ndlBusiness" IsAnimated="True" Value="50" Brush="Gray" Thickness="3" telerikDataViz:RadRadialGauge.IndicatorRadiusScale="0.83"/>

 </telerikDataViz:RadRadialGauge>

Please help me. Thanks in advance.

Hello Madhan,

Thank you for your question.

Due to limitations of the WinRT framework, sometimes the names of items in collections cannot be resolved and this is the case with the gauge indicators. Nevertheless, you can access the properties of the indicators through the RadRadialGaude properties, for example here are the steps to access the Length of a BarIndicatorSegment:

1. The RadRadialGauge has an Indicators property that holds a collection of all indicators currently added to the gauge. You can access the SegmentedRadialGaugeIndicator through this property as you iterate through all items and check their types. 
2. Then you can access the BarIndicatorSegment collection through the Segments property of the SegmentedRadialGaugeIndicator.
3. Finally you can change the Length property of the BarIndicatorSegment items.

Analogically, you can access every other property of the gauge indicators. I have also prepared a runnable sample application, based on your code, that demonstrates how you can achieve this in practice.

I hope this was useful and let me know if there is anything else we can help you with.
