OpenFileDialog Behaviour

[QQ]

I have the following code :

OpenFileDialog filedlg = new OpenFileDialog();

filedlg.InitialDirectory = directory.Text;

filedlg.Filter = "lvl files (*.lvl)|*.lvl" ;
filedlg.FileName = "*.lvl";
filedlg.ValidateNames = false;

if (filedlg.ShowDialog() == DialogResult.Cancel)
return;

string dirname = Path.GetDirectoryName(filedlg.FileName);

I set the property ValidateNames to false. I didn't select any file when
the dialog box pop-ups. When I click the "Open" button, the dialog box was
closed. The problem is filedlg.FileName doesn't not contain anything. I
expect it to have something like this c:\Test\*.lvl (with Win32
OpenFileDialog, it will). The protected member of OpenFileDialog namely
fileNames and FileNameInternal do have the value but as it is a protected
member, the value is inaccessible. ). Can anyone help ?
