[Mono-dev] Patch for different behavior on Auto-Check RadioButton

[jingnan si]

Hi,
   When using several auto-check RadioButton, the order of event notify has
problem which prevent my applcation work correctly. for example
RadioButtonA (checked) RadioButtonB (unchecked)

when user clicked on RaidoButtonB, the current implementation is
1) RadioButtonA CheckedChangedEvent
2) RadioButtonB Checked = true
3) RadioButtonB CheckedChangeEvent

so when user test RadioButtonA.Checked and RadioButtonB.Checked property in
the event handler of RadioButtonA.CheckedChange event, both of them are
false.

It is not the same behavior as MS .Net framework.

I create a simple patch to make the same as MS .net. just update the check
state before call UpdateSibling

Reagards,

diff -r
mono-2.0/mcs/class/Managed.Windows.Forms/System.Windows.Forms/RadioButton.cs
original/mono-2.0/mcs/class/Managed.Windows.Forms/System.Windows.Forms/RadioButton.cs

<                     check_state = CheckState.Checked;

>                     check_state = CheckState.Checked;
