Remarks

Use the EnableImprovedColumnSizing property to switch between legacy and updated column width calculation modes:

• legacy mode - column width changes dynamically depending on TreeList settings and node levels.
• updated mode - the TreeListColumn.MaxWidth and TreeListColumn.MinWidth settings work as expected, meaning you can set a column to a specific size that will remain unchanged.

The figure below illustrates the difference between these modes. The “Name” column’s width equals 120 , TreeListColumn.MinWidth is 30 , and the TreeListOptionsView.BestFitNodes is set to Visible. When the EnableImprovedColumnSizing setting is off, this “Name” column ignores its width setting and behaves according to the BestFitNodes property: shrinks when collapsed. If the EnableImprovedColumnSizing setting is enabled, column widths are constant in both expanded and collapsed states.
