SpreadsheetFileManagerValidationSettings.MaxFileSize Property

Gets or sets the maximum size of an uploaded file.

Namespace:DevExpress.Web.ASPxSpreadsheet
Assembly:DevExpress.Web.ASPxSpreadsheet.v17.2.dll

Expanded Syntax

Property value

Type: Int64
An Int64 value that specifies the maximum file size, in bytes.
The default is 31457280.

Expanded Remarks

By default, the FileManagerSettingsUpload.UseAdvancedUploadMode (accessed via the SettingsDocumentSelector.UploadSettings) is set to true, and the Advanced Upload Mode is used by Spreadsheet to upload files. In this mode, use the MaxFileSize property to specify the maximum size for uploaded files.

To ensure that file uploading works properly in advanced mode, ASPxUploadProgressHttpHandler should be registered in the web.config file. You can register it manually (see the ASPxUploadProgressHttpHandler topic) or use the DevExpress Project Converter that registers the handler in the web.config file automatically when it converts a project.
