Hi,
I tried to set FontSize of a RadSplitButton in the designer, or set it in the code like: this.radSplitButton1.Font = new System.Drawing.Font(...).
But nothing changed.
Finally I found the way which works:
this.radSplitButton1.DropDownButtonElement.ActionButton.Font = new System.Drawing.Font(...).
It's so complex just to change a Font.
