I have problem. I placed RadNumericUpDown control and set its value to 15 for default.
Now, I added event for ValueChanged:
sender, RadRangeBaseValueChangedEventArgs e)
HSdValue.Value = 0.2 * FVSdValue.Value;
When I start application I'm getting NullReferenceException - the object couldn't be found (Object reference not set to an instance of an object.
This happens also for other controls. What am I doing wrong?
The HSdValue is also RadNumericUpDown, located below the FVSdValue.
