On these larger screens, it makes sense to scale the page to the width of the container or to fit a whole page into the visible area to use the complete space of the screen. TX Text Control provides the [ZoomFactor](https://docs.textcontrol.com/textcontrol/windows-forms/ref.txtextcontrol.textcontrol.zoomfactor.property.htm) property that sets the zoom factor, in percent, for a TextControl. The following method fits the current page to fill it's container: ``` private void FitToWindow() { textControl1.PageUnit = MeasuringUnit.Twips; int iVisibleGap = 65; // get resolution to calculate convert twips 1/100 inch Graphics g = textControl1.CreateGraphics(); int iTwipsPerPixel = (int)(1440 / g.DpiX); SectionFormat currentSection = textControl1.Sections.GetItem().Format; double widthZoom = 100 * textControl1.Width / ((currentSection.PageSize.Width / iTwipsPerPixel) + iVisibleGap); double heightZoom = 100 * textControl1.Height / ((currentSection.PageSize.Height / iTwipsPerPixel) + iVisibleGap); if (widthZoom < heightZoom) textControl1.ZoomFactor = (int)widthZoom; else textControl1.ZoomFactor = (int)heightZoom; } ``` The next method shows how to set the zoom factor to fill the whole width of the container: ``` private void FitToWidth() { textControl1.PageUnit = MeasuringUnit.Twips; int iVisibleGap = 200; // get resolution to calculate convert twips 1/100 inch Graphics g = textControl1.CreateGraphics(); int iTwipsPerPixel = (int)(1440 / g.DpiX); SectionFormat currentSection = textControl1.Sections.GetItem().Format; double widthZoom = 100 * textControl1.Width / ((currentSection.PageSize.Width / iTwipsPerPixel) + iVisibleGap); textControl1.ZoomFactor = (int)widthZoom; } ``` --- ## About Bjoern Meyer As CEO, Bjoern is the visionary behind our strategic direction and business development, bridging the gap between our customers and engineering teams.
