C# OpenFileDialog Lock To Directory

Question

I am making a software that needs to ONLY be able allow people to select files and folders using the OpenFileDialog that are in the same directory as the program and that are in deeper folders. I don't want the OpenFileDialog to be able to select stuff outside of the program's current directory. Is this possible to do in C# using the OpenFileDialog?

Please let me know

Thanks

Answer 1

I don't see any out of the box support by the OpenFileDialog Control. However, you can try the following,

Set the InitialDirectory property to your program path. Then if a user selects a particular path outside of your program path, use the FileOk event to check this and bring him back to the InitialDirectory.

If you want much more control then you will have to write your custom dialog.

This is how I did it.

   openFileDialog1.InitialDirectory = Path.Combine(Path.GetDirectoryName(Application.StartupPath), "FolderName");

        if (openFileDialog1.ShowDialog() == DialogResult.OK)
        {            
                while(Path.GetDirectoryName(openFileDialog1.FileName) != Path.Combine(Path.GetDirectoryName(Application.StartupPath), "FolderName")){

                    MessageBox.Show("Please select .EXE which is in the default folder", "Wrong folder", MessageBoxButtons.OK, MessageBoxIcon.Information);
                openFileDialog1.ShowDialog();

            }                       
        }
