ControlFormat Object (Excel)
Contains Microsoft Excel control properties.
Example
Use the ControlFormat property to return a ControlFormat object. The following example sets the fill range for a list box control on worksheet one.
Note
If the shape isn’t a control, the ControlFormat property fails; and if the control isn’t a list box, the ListFillRange property fails.
Worksheets(1).Shapes(1).ControlFormat.ListFillRange = "A1:A10"
