RadioButton column in System.Windows. Forms.DataGrid

[Dmitry V. Markin]

Good day!

Here is my problem: I need to have a radiobutton column in my DataGrid for a
representation of a bool column, where only row can be checked at one
time(only one value in bool column can be true). So I've created a class
inheriting from DataGridColumnS tyle and added the following code to the class:

protected RadioButton [] rb ;

....
protected override void Paint(
Graphics g,
Rectangle bounds,
CurrencyManager source,
int rowNum,
Brush backBrush,
Brush foreBrush,
bool alignToRight)
{
Rectangle rect = bounds;
g.FillRectangle (backBrush,rect );
if(Convert.ToBo olean(GetColumn ValueAtRow(sour ce, rowNum)))
rb[rowNum].Checked = true;
else
rb[rowNum].Checked = false;
rb[rowNum].Bounds = new Rectangle
(bounds.X + 2, bounds.Y + 2,
bounds.Width - 4, bounds.Height - 4);
}

protected override void SetDataGridInCo lumn(DataGrid value)
{
base.SetDataGri dInColumn(value );
if(value != null)
{
if(value.DataSo urce!=null)
{
CurrencyManager source =
(CurrencyManage r)value.Binding Context[value.DataSourc e];
rb = new RadioButton[source.Count];
for(int i=0;i<source.Co unt;i++)
{
rb[i] = new RadioButton();
rb[i].Visible = true;
rb[i].CheckedChanged +=new EventHandler(Ra dioButtonValueC hanged);
value.Controls. Add(rb[i]);
}
}
}
}

private void RadioButtonValu eChanged(object sender, EventArgs e)
{
RadioButton rb1 = (RadioButton)se nder;
CurrencyManager source =
(CurrencyManage r)((DataGrid)rb 1.Parent).Bindi ngContext[((DataGrid)rb1. Parent).DataSou rce];
for(int i=0; i< source.Count; i++)
{
source.Position = i;
if(rb1.Equals(r b[i]))
SetColumnValueA tRow(source, i , true);
else
SetColumnValueA tRow(source, i, false);
}
}
So here I've faced some problems:
1. when I sort the datagrid, the checked radiobutton doesn't change it's
positions, seems like CurrencyManager stays the same.
2. when I use dataview with some rowfilter as a source for my datagrid,
checking radiobutton constanly throws Out of Index exception.
3. do I really have to change source.position in cycle(otherwise , it
throws an exception)?

Thanks in advance.

Found out solutions to most of my problems, except for one: after I click on
the column header of DatGrid control, Sort property of the DataView I'm using
as a source for a DataGrid doesn't seem to change :(
