http://bugzilla.novell.com/show_bug.cgi?id=624915#c0 Summary: calling ExpandAll() on a TreeView contain in a small panel can throw ArgumentOutOfRangeException. Classification: Mono Product: Mono: Class Libraries Version: SVN Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Windows.Forms AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: --- Blocker: --- Created an attachment (id=377907) --> (http://bugzilla.novell.com/attachment.cgi?id=377907) Test case showing bug. User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.0.249.43 Safari/532.5 Adding a TreeView with DockStyle.Fill to a Form with height of 50, then calling ExpandAll() on the Tree, throws a ArgumentOutOfRangeException. The Vertical scrollbar gets set to a negative value. This happens in a block of code labeled: /// /// Everything below this is basically an emulation of a strange bug on MS /// where they don't always scroll to the last node on ExpandAll /// So I think making this more robust might be a good way to fix it. ie. : vbar.Value = Max(vbar.Minimim, vbar.Maximum - VisibleCount + 1) This block of code sets vbar.Value directly in one place and indirectly via a call to SetTop(). Reproducible: Always Steps to Reproduce: 1. Compile and Run Small Test Program 2. Click button that says ClickMe Actual Results: System.ArgumentOutOfRangeException: '5' is not a valid value for 'Value'.
