public bool ThreeState {get; set;}

Property Value

Boolean: true if check box has three states; false if only two
Remarks

Check boxes can be either two-state (with true and false) or three-state (with true, false, and indeterminate).

If you want to allow the check box to be three-state, set the value to true.

Example
This example sets the properties of a three-state check box in a cell and specifies the text for each state.
FarPoint.Win.Spread.CellType.CheckBoxCellType ckbxcell = new FarPoint.Win.Spread.CellType.CheckBoxCellType();
ckbxcell.ThreeState = true;
ckbxcell.TextTrue ="Checked";
ckbxcell.TextFalse ="Unchecked";
ckbxcell.TextIndeterminate = "Not Sure";
fpSpread1.Sheets[0].Cells[1,2].CellType = ckbxcell;
Dim ckbxcell As New FarPoint.Win.Spread.CellType.CheckBoxCellType()
ckbxcell.ThreeState = True
ckbxcell.TextTrue = "Checked"
ckbxcell.TextFalse = "Unchecked"
ckbxcell.TextIndeterminate = "Not Sure"
