I have several applications that open a SaveFileDialog, but it always comes up in "List" mode and I had not found a way of configuring the dialog to display in "Details" mode. This is a kludgy work-around, but it seems to work OK. After Declaring the dialog in your code and just prior to calling the dlg.ShowDialog() method I include the line:
That seems to work to bring the dialog up in the "Details" mode.
I use it on XP, have not tried it on Vista or W7.
Enjoy! - hground
