## Description Used to get or set the state of the cell with the coordinates of *row*, *column* (zero-based). This assumes that the passed cell is a CheckBox cell. Use the CellType property to set a cell to a CheckBox cell. CheckedStates Enumeration is an `Enum` of the `CheckBox` class. ## Sample code The CellState method enables you to get or set the value of a tri-state Checkbox cell. Any cell of type TypeCheckbox box can store one of three values: Checked, Unchecked, and Indeterminate. To set up a cell as TypeCheckbox, use code such as this in the Open event: ``` xojo Me.CellType(1, 0) = ListBox.TypeCheckBox ``` --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- To change the state of the cell, use the CheckedStates enum of the `CheckBox` control: ``` xojo ListBox1.CellState(1, 0) = Checkbox.CheckedStates.Indeterminate ``` ## Compatibility All projects types on all supported operating systems.
