File Input

[0xor1]

The existing file input seems to restrictive in its usage. It would be nice to have a more basic version that simply returns a list of IBrowserFile OnChange, and lets you do what you need to do with it, rather than giving you back just the name and base64 string.

Check RadzenFileUpload. It supports that already.

maybe I'm missing something super obvious but the existing one only seems to support a single file and requires binding individual properties for file name and file size:

        /// <summary>
        /// Gets or sets the image file name.
        /// </summary>
        /// <value>The image file name.</value>
        [Parameter]
        public string FileName { get; set; }

        /// <summary>
        /// Gets or sets the FileName changed.
        /// </summary>
        /// <value>The FileName changed.</value>
        [Parameter]
        public EventCallback<string> FileNameChanged { get; set; }

        /// <summary>
        /// Gets or sets the image file size.
        /// </summary>
        /// <value>The image file size.</value>
        [Parameter]
        public long? FileSize { get; set; }

        /// <summary>
        /// Gets or sets the FileSize changed.
        /// </summary>
        /// <value>The FileSize changed.</value>
        [Parameter]
        public EventCallback<long?> FileSizeChanged { get; set; }

wouldn't it be more flexible and generic to have the value as List<IBrowserFile> Value and enable support to toggle multiple file selection? the existing implementation seems to be pretty hardcoded to a single file I've tried this in the examples on the docs page and it doesn't pick up the multiple selected files when I try:

@using RadzenBlazorDemos.Data
@using RadzenBlazorDemos.Models.Northwind

@inherits DbContextPage

<div class="container-fluid">
    <div class="row px-3">
        <div class="col-lg-6 offset-lg-3 p-3">
            <RadzenCard>
            <RadzenFileInput @bind-Value=@files TValue="List<IBrowserFile>" class="w-100" 
                Change=@OnChange Error=@(args => OnError(args, "FileInput")) InputAttributes="@(new Dictionary<string,object>(){ { "aria-label", "select file" }, { "multiple", true }})"/>
            </RadzenCard>
        </div>
    </div>
</div>

<EventConsole @ref=@console />

@code {
    List<IBrowserFile> files = new ();
    EventConsole console;

    string fileName;
    long? fileSize;

    void OnChange(List<IBrowserFile> value)
    {
        console.Log($"value: {value?.ToString()} files: {files?.ToString()}");
        console.Log($"value: {value?.Count} files: {files?.Count}");
    }

    void OnError(UploadErrorEventArgs args, string name)
    {
        console.Log($"{args.Message}");
    }
}
