#Remarks
Handle the FileUploadStart event to control file upload before it is started. Use the event argument’s FileInfo property to get information about the file (its name, type, size, and so on). Set the event argument’s Cancel
property to true
to cancel file upload.
The following snippet prohibits upload of files whose size exceeds 1MB.
<DxUpload Name="myFile" UploadUrl="https://localhost:10000/api/Upload/Upload/"
FileUploadStart="@OnFileUploadStart">
</DxUpload>
@code {
void OnFileUploadStart(FileUploadStartEventArgs e) {
if (e.FileInfo.Size > 1048576)
e.Cancel = true;
}
}
