Glossary Item Box

Gets or sets whether to allow the user to enter formulas in a cell in the component.


Visual Basic (Declaration) 
Public Property AllowUserFormulas As Boolean
Visual Basic (Usage)Copy Code
Dim instance As FpSpread
Dim value As Boolean
instance.AllowUserFormulas = value
value = instance.AllowUserFormulas
public bool AllowUserFormulas {get; set;}

Property Value

Boolean: true to allow users to enter formulas in cells; false otherwise


When this property is set to true, the user can press the equal sign key to type, display, or make modifications to formulas in cells. Even if this property is set to false, you can still provide formulas for cells programmatically using the Formula property (in the Cell, Row, or Column object). This property simply prevents users from entering formulas.

For more information on formulas, refer to the Formula Reference.


This example specifies that users are allowed to type formulas into cells in the Spread component.
