UploadedFile.IsValid Property

Gets a value indicating whether the uploaded file passes the validation criteria defined via the ASPxUploadControl.ValidationSettings property.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v23.1.dll

NuGet Package: DevExpress.Web

Declaration

C#

public bool IsValid { get; set; }

VB.NET

Public Property IsValid As Boolean

Property Value

Type	Description
Boolean	true if the file is valid; otherwise, false.

Remarks

Use the IsValid property to verify whether the uploaded file has passed the built-in validation whose criteria can be defined using the ValidationSettings property. Typically, the IsValid property can be used to determine whether a file is valid before saving the file (using the SaveAs(String) method, for instance).

Note that if an uploaded file’s validation fails, the IsValid and isValid properties are also automatically set to false.
