Control oControl = null;

Then later...

oControl = new MyRadioButton();
oControl.Text = sCaption;
oControl.Checked = Convert.ToBoolean(_DataRow[1]);

I'm getting

'System.Windows.Forms.Control' does not contain a definition for 'Checked' and no extension 
method 'Checked' accepting a first argument of type 'System.Windows.Forms.Control' could be found

Here's MyRadioButton

class MyRadioButton : RadioButton
{
}

So why isn't the Checked property there?
