Determines whether the specified value can be converted to a double-precision, floating point value and is between the minimum and maximum allowed values.

Syntax

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

Visual Basic (Usage)	Copy Code
Dim instance As PercentCellType Dim value As Object Dim value As Boolean value = instance.IsValid(value)

C#
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.
