Customize the SaveFileDialog

[sureshkumar_kc]

In C#, I am trying to create a windows control library using FileDialog.

public class UserControl1 : System.Windows.Forms.FileDialog
{

}

When I doing this I am getting the following error .

does not implement inherited abstract member 'System.Windows.Forms.FileDialog.RunFileDialog(Sys tem.Windows.Forms.NativeMethods.OPENFILENAME_I)'

But I could not noticed this RunFileDialog member in FileDialog member list.
Can you help me create sub class of the FileDialog

i.e....

I want to add a ComboBox to the SaveFileDialog, The SaveFileDialog class is sealed, and the documentation declares that its impossible to inherit from the FileDialog either . Is there a way around, or should I write a whole new form?

You can't inherit from a sealed class.

Don't create a whole new form, simply create a custom control that implements (but does not inherit from) a savefiledialog and a combobox.

Thanks RobertStout
But I am not getting how to implements that..

I want to add a ComboBox/textbox to the SaveFileDialog.
