DialogResult with FolderBrowserDialog in WPF

Question

First time I\'m implementing a FolderBrowserDialog in WPF and I\'m not loving it one bit...

Aside from the issues I had figuring out that Windows.Forms wasn\'t refer

Answer 1

Okay so it turns out all answers other answers here were right.

They just missed out one thing and I think that was my fault...

Every time I saw DialogResult in Intellisense when trying to use it in my if statement (as I've been told to use, I saw this:

bool? Window.Dialog.Result
Gets or sets the dialog result value, which is the value that is returned from the
System.Windows.Window.ShowDialog() method.

Exceptions:
System.InvalidOperationException

This particular DialogResult object isn't the one I was looking for.

What finally worked was the following:

DialogResult result = fbd.ShowDialog();

if (result == System.Windows.Forms.DialogResult.OK)
{
    // do work here
}

It's worth noting that I do have System.Windows.Forms referenced in my usings which is why I never thought to reference the class from System as in the above snippet. I thought it was using this anyway.

Answer 2

DialogResult.(OK, Cancel whatever you want to check),

if (result == DialogResult.OK) // DialogResult.(Your desired result, select from the list it generates)
{
    txtSource.Text = fbd.SelectedPath;
}

Answer 3

Late answer here but why not just . .

private void SelectFolder()
{
    var dialog = new FolderBrowserDialog();
    var status = dialog.ShowDialog(); // ShowDialog() returns bool? (Nullable bool)
    if (status.Equals(true))
    {
        SelectedFolderPath = dialog.SelectedPath;
    }
}

You can see the result in debugging session. It returns false when the Cancel button is clicked.

Answer 4

DialogResult is an enumeration and defines values to indicate the return values of dialogs.

In your code you should check for DialogResult.OK to init your variable with the path selected in the dialog. DialogResult.OK is returned when the "OK"-Button is pressed in the dialog, otherwise is DialogResult.Cancel returned.

if (result == DialogResult.OK){
  txtSource.Text = fbd.SelectedPath;
}
