ListBox.CellType Property
Syntax
CellType as Integer
Parameters are row, column (Integers). The first cell is 0,0.
Use the following class constants to set the CellType:
TypeDefault (0): Default, same as column type
TypeNormal (1): Normal
TypeCheckBox (2): Add checkbox
TypeEditable (3): Inline editable
For example:
lb1.CellType(1,1)=ListBox.TypeCheckBox
The values of CellType > 0 override ColumnType. For example, if ColumnType is 2, but a cell in the column has CellType set to 1, the cell will be normal.
