Hi there!
I'm using a XamNumericEditor to edit a decimal property on my ViewModel. The ValueType is set to System.Decimal. While debugging from visual studio, the control is extremely unresponsive. I investigated using profiling tools and such and discovered that the control was causing a lot of exceptions to be thrown. I disabled the "Just my Code" setting and enabled managed breakpoints and discovered that this exception is thrown nearly constantly (10-15 times per keystroke):
System.FormatException occurred Message=Input string was not in a correct format. Source=mscorlib StackTrace: at System.Number.ParseDouble(String value, NumberStyles options, NumberFormatInfo numfmt) Infragistics3.Wpf.Editors.v10.1.dll!Infragistics.Windows.Editors.FractionPart.GetFractionValue() + 0x13b bytes Infragistics3.Wpf.Editors.v10.1.dll!Infragistics.Windows.Editors.FractionPart.CanSpin(bool up = true) + 0x52 bytes Infragistics3.Wpf.Editors.v10.1.dll!Infragistics.Windows.Editors.EditInfo.CanSpin(bool up = true, object amount) + 0x130 bytes Infragistics3.Wpf.Editors.v10.1.dll!Infragistics.Windows.Editors.EditInfo.CurrentState.get() + 0x396 bytes
It performs much better outside of the debugger which probably explains why it was missed during testing (assuming you tested the scenario :-)).
Hello,
You can set the ValueType property of the editor to Decimal so that it does not try to parse from Double (which is the default for XamNumericEditor).
xmlns:sys="clr-namespace:System;assembly=mscorlib"
<igEditors:XamNumericEditor Value="{Binding Decimal}" ValueType="{x:Type sys:Decimal}" />
You can also use XamCurrencyEditor directly.
