DxFileInput.RemoveAllFiles() Method

In This Article

Clears the file list.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

#Declaration

C#
public void RemoveAllFiles()

#Remarks

Note

RemoveFile, RemoveFiles, and RemoveAllFiles methods ignore files that are being uploaded.

Once a user selects files in the Open dialog or drags files onto a drop zone, the File Input component adds these files to the file list. The file list displays each file’s upload status and upload, cancel, reload, and remove buttons. On the image below, the file list contains 4 files in different states:

file list

Handle the SelectedFilesChanged event to access the collection of files in the file list. Call the following methods to manage these files in code:

Start Upload Cancel Upload Restart Canceled Upload Remove Files from List
One File UploadFile CancelFileUpload ReloadFile RemoveFile
Multiple Files UploadFiles CancelFilesUpload ReloadFiles RemoveFiles
All Files UploadAllFiles CancelAllFilesUpload ReloadAllFiles RemoveAllFiles

The following example displays a button that removes all files from the file list:

Razor
<DxFileInput @ref="MyFileInput"
             AllowMultiFileUpload="true"
             UploadMode=UploadMode.OnButtonClick
             FilesUploading="OnFilesUploading" />

<DxButton Text="Remove All Files" Click="OnRemoveButtonClick" />

@code {
    DxFileInput MyFileInput { get; set; }

    void OnRemoveButtonClick() {
        MyFileInput.RemoveAllFiles();
    }
    async Task OnFilesUploading(FilesUploadingEventArgs args) {
        foreach (var file in args.Files) {
            /* The following code is intended for demonstration purposes only.
            Do not read a stream directly in memory to avoid performance and security-related issues. */
            using var stream = new System.IO.MemoryStream();
            await file.OpenReadStream(file.Size).CopyToAsync(stream);
        }
    }
}
