Fixed (anchored) columns can improve data readability as they remain visible when a user scrolls the TreeList horizontally.

The DevExpress Blazor TreeList allows you to anchor columns to the TreeList's left or right edge. To introduce this capability in your next DevExpress-powered Blazor app, set the column's FixedPosition property to Left or Right.

Just as with standard columns, users can display/hide fixed columns or change order and size. However, users cannot move standard columns to a fixed column zone and vice versa.

In this demo, the Name and Type columns are anchored to the TreeList's left and right edges, respectively. Scroll the TreeList horizontally to view how this affects data readability.
