float property of custom user control are not handled correctly if negative

[stefanofraccaro]

I have an UserControl (WinForms) that has a MinValue and MaxValue properties. Seems that both properties are setted to zero only switching from Source/Design.

I have a test case : www.stefanofraccaro.org/sd_bug.zip

How to reproduce :

[stefanofraccaro]

Set MinValue to -80 Set MaxValue to -20 Switch to Source Code Switch to Design Mode MinValue is 0 (expected -80) MaxValue is 0 (expected -20)

SharpDevelop Version : 5.1.0.4936-Beta-3ea20cfa .NET Version : 4.5.50938 OS Version : Microsoft Windows NT 6.1.7601 Service Pack 1 Current culture : Italian (Italy) (it-IT) Running under WOW6432, processor architecture: x86-64 Working Set Memory : 89828kb GC Heap Memory : 10793kb

The same project works correctly with SD 4.4 :bug:

There was a similar Bug in the WPF Designer! There were the Min/Max values of the Up/Down Controls wrong! Maybe something similar in Winforms?

Any news about this bug? I have a custom control with MinValue -100 and MaxValue +100 that changes everytime to 0-100 :-( If you don't have enough time, tell me please where I can look inside the SharpDevelop code

Similar problem with Chart.ChartArea.Axis.Minimum in particular (and other properties in the Chart). Currently I work round the problem by setting the properties in the form constructor

Any news about that?

I written a "patch" 2 year ago : is it possible to merge the patch? It is very small and seems to workaround the problem. Maybe a developer can write better the patch in no more than 5 minutes.
