The progressiveTimeHeaderRenderingMargin property (number) specifies how many extra horizontal pixels of time headers are rendered on each side of the viewport.
Declaration
DayPilot.Gantt.progressiveTimeHeaderRenderingMarginDefault Value
200Notes
Applies when progressiveTimeHeaderRendering is enabled. Increase the margin if custom headers appear too late during scrolling. A larger margin uses more memory and can increase loading time.
Accepts a finite, nonnegative number. Invalid values use the default of 200. A value of 0 removes the extra margin.
Available since version 2026.4.7080 of DayPilot Pro for JavaScript.
