Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v23.1.dll

NuGet Package: DevExpress.Blazor


public string UploadUrl { get; set; }

Property Value

Type Description

The upload URL.


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).

The Upload component’s UploadUrl property specifies a path of a server-side controller’s action that processes all the upload requests. Use the event argument’s UploadUrl property to change the controller action based on conditions. The snippet below changes the upload URL for PNG files.

<DxUpload Name="myFile" UploadUrl="https://localhost:10000/api/Upload/Upload/" 

@code {
    void OnFileUploadStart(FileUploadStartEventArgs e) {
        if (e.FileInfo.Type == "image/png")
            e.UploadUrl = "https://localhost:10000/api/Upload/UploadPng/";
