When file upload is in progress, users can click the cancel button to interrupt file upload. Handle the FileUploadAborted event to respond to this action.

Use the CancelFilesUpload method to cancel specific files upload in code. The snippet below allows users to upload multiple files and displays a button that cancels upload of the first two files on click.

<DxUpload UploadMode=UploadMode.OnButtonClick
          SelectedFilesChanged="@SelectedFilesChanged" 
          AllowMultiFileUpload="true"
          @ref="MyUpload" >
</DxUpload>

<DxButton Text="Cancel Upload of Two Files" Click=OnButtonClick />

@code {
    bool UploadVisible { get; set; } = false;
    IEnumerable<UploadFileInfo> Files { get; set; }
    IEnumerable<UploadFileInfo> FirstFiles { get; set; }
    DxUpload MyUpload { get; set; }

    protected void SelectedFilesChanged(IEnumerable<UploadFileInfo> files) {
        Files = files;
        UploadVisible = files.ToList().Count > 0;

        InvokeAsync(StateHasChanged);
    }

    void OnButtonClick(){
        FirstFiles = Files.Take(2);
        MyUpload.CancelFilesUpload(FirstFiles);
    }
}
