Question

I have this query to collection:

Panel thePanel = menuCell.Controls.OfType<Panel>()
                    .Where(panel => panel.Controls.OfType<HyperLink>().Any(
                        label => label.ID == clas))
                    .FirstOrDefault();

This gets only the Panel that has an hyperlink with a certain id. I need to get not only the firstOrDefault but the matched element (only the first) and the 2 next within the sequence. I didn’t try anything because don’t know how.

Answer 1

This will return first three panels, which have hyperlinks with a certain id

var thePanels = menuCell.Controls.OfType<Panel>()
                    .Where(panel => panel.Controls.OfType<HyperLink>()
                                         .Any(label => label.ID == clas))
                    .Take(3);

If you need first panel which have hyperlinks with a certain id, and next two panels whatever they have:

var thePanels = menuCell.Controls.OfType<Panel>()
                        .SkipWhile(panel => !panel.Controls.OfType<HyperLink>()
                                                 .Any(label => label.ID == clas))
                        .Take(3);
