Declaration

Public Property EnableImprovedColumnSizing As Boolean

Property Value

Type Description
Boolean

true if the updated mechanism is enabled; otherwise, false.

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.
