OpenFileDialog control - multiselect 2

[Katy44]

I am using an OpenFileDialog, and want the users to ba able to select many files in one go. I think the Multiselect property is what I want, but I'm not sure if I understand it exactly. Does it allow, opening the explorer window once, the user to select many files by holding down the Ctrl key while they select the files? If that is the case then it's not working for me - holding down Ctrl doesn't allow multiple selections, the usual Windows 'lasoo' isn't available etc.
Have I got the completely wrong idea?
Thanks for any help.

Yes, it is the multiselect property that should do what you are looking for. Here's some example code that opens up a OpenFileDialog and allows a use to select multiple files, then adds them to a listbox named lstAdditionalFiles.

OpenFileDialog myDialog = new OpenFileDialog();
myDialog.RestoreDirectory = true;
myDialog.Multiselect = true;

if (myDialog.ShowDialog(this) == DialogResult.OK)
{
     foreach(string file in myDialog.FileNames)
     {
        // Fill in location selected
        this.lstAdditionalFiles.Items.Add(file); 
     }
}

If you set the multi-select property to true, it should allow you to pick multiple entries with the control key.

Thank you that's what I thought. Do you have any idea why it's not working?
I'll start a completely new, very small windows app to test it.
Thanks for your help.

That's weird - it works perfectly.
Well now I know it can work as I want, I will get it to work!
Thanks a lot.
