If you increase the font size in the sheet tabs larger than the default, you might want to use the HorizontalScrollBarHeight property to change the height of the tab strip.
FarPoint.Win.Spread.SheetTab st; st = fpSpread1.TabStrip.ActiveSheetTab; st.Font = new Font("Comic Sans MS", 12);
Dim st As FarPoint.Win.Spread.SheetTab st = FpSpread1.TabStrip.ActiveSheetTab st.Font = New Font("Comic Sans MS", 12)
