Hello Umer,

Thank you for writing.

You can refer to our Demo application >> Gauges >> First look example where on a Timer.Tick the RadRadialGauge.Value is updated. Additionally, you can have a look at our Gauges >> Getting started help article >> Clock example. If you are still unable to achieve the exact requirement, please specify in details what you are trying to accomplish. Thus, we would be able to assist you further.

I hope this information helps. Should you have further questions, I would be glad to help.

Regards,

Hello Umer,

Thank you for writing back.

Following the examples from the referred Demo application and online documentation, I have prepared a sample code snippet demonstrating how to manipulate the RadRadialGauge.Value property on a Timer.Tick. Note that the RadialGaugeNeedle.BindValue property is set to true in order to indicate that the needle's value is bound to the gauge's value. In the code snippet below the value is set to a random generated number just for the example. You can use any custom object's property according to your specific requirement:
Random rand = new Random();
public Form1()
{
InitializeComponent();

Timer timer = new Timer();
timer.Interval = 1000;
timer.Tick+=timer_Tick;
timer.Start();

}

private void timer_Tick(object sender, EventArgs e)
{
}

The attached gif file illustrates the behavior on my end. If it does not suit your scenario, it would be greatly appreciated if you give us more details about the exact requirement that you trying to achieve when manipulating the needle. Thank you.

I hope this information helps. If you have any additional questions, please let me know.
