How to check multiple elements for an empty string in WPF?

Question

WPF

Good afternoon! In my WPF project, there are several TextBlocks included in a StackPanel (Name = MainPanel), how can I loop through all of them for an empty string?

Answer 1

bool isEmpty = MainPanel.Children
    .OfType<TextBlock>()
    .Any(s => string.IsNullOrWhiteSpace(s.Text));
