Summary: ListControl etc: AOOREx on first add to bound
IBindingList
Product: Mono: Class Libraries
Version: unspecified
Platform: Other
OS/Version: Other
Status: NEW
Severity: Normal
Priority: P5 - None
Component: Windows.Forms
AssignedTo: mono-bugs at ximian.com
ReportedBy: andyhume32 at yahoo.co.uk

With code of the following form ComboxBox/ListControl throw
ArgumentOutOfRangeException when first adding to the list
[[
IBindindList ibl = new BindingList<int32>();
ComboBox cb = new ComboBox()
cb.DataSource = ibl;
// ...
// list is empty and bound, first add -> exception
ibl.Add(99); //**
]]
Note that except for this particular case the data binding seems to work well
for my purposes. Adding items updates any bound controls, navigating the list
in one control causes navigation in the others, etc. So fixing this corner
case would allow one to use this functionality.
The sample app can be configured to start with an non-empty list (give it any
dummy command-line option) and you'll see the working behaviour. Run without
any command-line options hit <Do Fill> and see the exception.
The exception in full is
[[
Unhandled Exception: System.ArgumentOutOfRangeException: Argument is out of
range.
Parameter name: SelectedIndex0

The same occurs if using a ListBox too.
Repro is
[[
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
using System.ComponentModel;
class ListControlIBindingList
{
static void Main(string[] args)
{
bool nonEmptyWhenBound = false;
//
if (args.Length > 0)
nonEmptyWhenBound = true;
//
Foo(nonEmptyWhenBound);
}
static IBindingList m_ibl;
static void buttonDoFill_Click(object sender, EventArgs e)
{
// The bug occurs here, the list is empty and bound,
// now add an item to it. Crash. Occurs when empty list ->
item added.
m_ibl.Add(new Version(3, 1));
m_ibl.Add(new Version(3, 2));
m_ibl.Add(new Version(3, 3));
}
private static void Foo(bool nonEmptyWhenBound)
{
Form f = new Form();
f.Text = "ListControlIBindingList";
FlowLayoutPanel flp = new FlowLayoutPanel();
f.Controls.Add(flp);
//
m_ibl = new BindingList<Version>();
bool skipBug = false || nonEmptyWhenBound;
if (skipBug) {
m_ibl.Add(new Version(0, 99));// NON-EMPTY at bound Add
}
//
ListControl cb = new ComboBox();
cb.DataSource = m_ibl;
flp.Controls.Add(cb);
//
Button b = new Button();
b.Text = "Do Fill";
b.Click += buttonDoFill_Click;
flp.Controls.Add(b);
//
//cb = new ComboBox();
cb = new ListBox();
cb.DataSource = m_ibl;
flp.Controls.Add(cb);
//
Application.Run(f);
}
}//class
