Syntax

Visual Basic
C#

'Declaration
 
Public Overrides Function IsValid( _
   ByVal value As Object _
) As Boolean

'Usage
 
Dim instance As PercentCellType
Dim value As Object
Dim value As Boolean
 
value = instance.IsValid(value)

public override bool IsValid( 
   object value
)

Parameters

value: Value to validate (as object)

Return Value

Boolean: true if the value can be converted to a double-precision, floating-point value and is between the minimum and maximum value; false otherwise

Remarks

The valid range of values is defined by the MinimumValue and MaximumValue properties.

Example

This examples returns if the value in the cell is valid.

FarPoint.Win.Spread.CellType.PercentCellType p = new FarPoint.Win.Spread.CellType.PercentCellType(); 
bool b; 
fpSpread1.ActiveSheet.Cells[0, 0].CellType = p; 
fpSpread1.ActiveSheet.Cells[0, 0].Value = 0.05; 
b = p.IsValid(fpSpread1.ActiveSheet.Cells[0, 0].Value); 
MessageBox.Show(b.ToString());

Visual Basic

FarPoint.Win.Spread.CellType.PercentCellType p = new FarPoint.Win.Spread.CellType.PercentCellType(); 
bool b; 
fpSpread1.ActiveSheet.Cells[0, 0].CellType = p; 
fpSpread1.ActiveSheet.Cells[0, 0].Value = 0.05; 
b = p.IsValid(fpSpread1.ActiveSheet.Cells[0, 0].Value); 
MessageBox.Show(b.ToString());
