In this example, only the data cells of the first split are affected. This is because the split caption, column headers, and column footers inherit their fonts from the built-in styles Caption, Heading, and Footing, respectively.

The following code affects data cells only in the first split:

To write code in Visual Basic

Dim myfont As Font        
myfont = New Font(Me.C1List1.Splits(0).Style.Font, FontStyle.Bold)        
Me.C1List1.Splits(0).Style.Font = myfont

To write code in C#

Font myfont;        
myfont = new Font(this.c1List1.Splits[0].Style.Font, FontStyle.Bold);        
this.c1List1.Splits[0].Style.Font = myfont;
