trouble with combobox selectedIndex

Okay, the user chooses something from the child window's combobox, presses the button and in the main window canvas is filled with a color. that is the point, but the same thing happens if a user presses "X" also. I want for the computer to see the difference in "X" and the button i created for that purpose.

Questionnaire q = new Questionnaire();
        q.ShowDialog();


        var color = q.comboBox1.SelectedIndex;
        switch (color)
        {
            case 0:
                Canvas.Background = new SolidColorBrush(Color.FromArgb(255, 0, 128, 0));
                break;
            case 1:
                Canvas.Background = new SolidColorBrush(Color.FromArgb(255, 128, 128, 128));
                break;
            case 2:
                Canvas.Background = new SolidColorBrush(Color.FromArgb(255, 211, 211, 211));
                break;
            case 3:
                Canvas.Background = new SolidColorBrush(Color.FromArgb(255, 255, 127, 80));
                break;
            case 4:
                Canvas.Background = new SolidColorBrush(Color.FromArgb(255, 128, 128, 0));
                break;
            case 5:
                Canvas.Background = new SolidColorBrush(Color.FromArgb(255, 255, 222, 173));
                break;

this code is written in MainWindowButton_ClickEvent which opens up the child Window. Also i have tried with Window_Closed and Window_Closing to fix the problem by setting SelectedIndex to -1, But all it does is always return -1 and not filling canvas regardless of the button pressed. I have also tried with DialogResult to false. None of it work.

Try to set the DialogResult property of the Questionnaire window before you close it in the button click event handler:

private void CloseButton_Click(object sender, RoutedEventArgs e)
{
    DialogResult = true;
    Close();
}

You can then check the value that is returned from the DialogResult method to determine whether the button was clicked:

Questionnaire q = new Questionnaire();
bool? result = q.ShowDialog();

if(result.HasValue && result.Value)
{
    //button was clicked
    var color = q.comboBox1.SelectedIndex;
    switch (color)
    ...
}
