Class UploaderFiles

Represents a component that specifies the list of files that will be preloaded on rendering of the SfUploader component.

Inheritance

System.Object

UploaderFiles

Namespace: Syncfusion.Blazor.Inputs

Assembly: Syncfusion.Blazor.dll

Syntax

public class UploaderFiles : OwningComponentBase

Remarks

The UploaderFiles component allows you to define files that should be displayed as already uploaded when the SfUploader component is initially rendered. This is useful for scenarios where you want to show previously uploaded files or files that exist on the server. The component manages a collection of UploaderUploadedFiles objects that represent the preloaded files.

Examples

The following example shows how to use the UploaderFiles component to preload files in an uploader.

<SfUploader>
    <UploaderFiles>
        <UploaderUploadedFiles Name="document.pdf" Size="1024000" Type="application/pdf"></UploaderUploadedFiles>
        <UploaderUploadedFiles Name="image.jpg" Size="512000" Type="image/jpeg"></UploaderUploadedFiles>
    </UploaderFiles>
</SfUploader>

Constructors

UploaderFiles()

Declaration

public UploaderFiles()

Properties

Files

Gets or sets the collection of uploaded files that are preloaded in the SfUploader component.

Declaration

public List<UploaderUploadedFiles> Files { get; set; }

Property Value

Type	Description
System.Collections.Generic.List<UploaderUploadedFiles>	A System.Collections.Generic.List<> of UploaderUploadedFiles objects representing the preloaded files. The default value is an empty list.

Remarks

This property contains the list of files that will be displayed as already uploaded when the SfUploader component is rendered. Each file in the collection is represented by an UploaderUploadedFiles object that contains file metadata such as name, size, and type. The files in this collection are automatically added to the uploader's file list during component initialization.

Examples

The following example shows how to access and work with the Files collection.

// Access the files collection
var uploaderFiles = new UploaderFiles();
uploaderFiles.Files.Add(new UploaderUploadedFiles 
{ 
    Name = "document.pdf", 
    Size = 1024000, 
    Type = "application/pdf" 
});

Methods

BuildRenderTree(RenderTreeBuilder)

Declaration

protected override void BuildRenderTree(RenderTreeBuilder __builder)

Parameters

Type	Name	Description
Microsoft.AspNetCore.Components.Rendering.RenderTreeBuilder	__builder

ComponentDispose(Boolean)

Releases the unmanaged resources used by the UploaderFiles component and optionally releases the managed resources.

Declaration

protected void ComponentDispose(bool disposing)

Parameters

Type	Name	Description
System.Boolean	disposing	true to release both managed and unmanaged resources; false to release only unmanaged resources.

Remarks

This method is called when the component is being disposed to clean up resources and prevent memory leaks. When disposing is true, the method releases managed resources including clearing the Parent reference and the Files collection. This ensures proper cleanup of component references and prevents potential memory leaks in the application.
