Hi there, I have installed several gauges with Inner gauge in my program. I need to update the gauges periodically. The program I have is as below: // update gauges private void timer2_Tick_1(object sender, EventArgs e) { radialGauge4.BeginInvoke((MethodInvoker)delegate { radialGauge4.MainValue = ReceiveSCSStatus.SCMDUCMtrspd_val; }); radialGauge1.BeginInvoke((MethodInvoker)delegate { radialGauge1.MainValue = DynoRPM_val; }); . . . } The problem for above code is: this periodic call slows down my program performance. So I tried to update the gauges only when there is a change of the main value. The new code is as below: // update gauges private void timer2_Tick_1(object sender, EventArgs e) { if (ReceiveSCSStatus.SCMDUCMtrspd_val != Last_SCMDUCMtrspd_val) { radialGauge4.BeginInvoke((MethodInvoker)delegate { radialGauge4.MainValue = ReceiveSCSStatus.SCMDUCMtrspd_val; }); } if (DynoRPM_val != Last_DynoRPM_val) { radialGauge1.BeginInvoke((MethodInvoker)delegate { radialGauge1.MainValue = DynoRPM_val; }); } . . . } This way is theoretically correct. But when I run the program and change the main value, the Inner gauge display does not got changed automatically. Only when I break inside the loop, and run program again, then the new value comes out on the Inner gauge display . Do you know why this happens? Also, when I design the gauges, the '.MainValue' is defaulted to
