Provides information about the BeforeRemove event callback.

Inheritance

System.Object

BeforeRemoveEventArgs

Namespace: Syncfusion.Blazor.Inputs

Assembly: Syncfusion.Blazor.dll

Syntax

public class BeforeRemoveEventArgs : Object

Remarks

This event is triggered before files are removed from the uploader component. It provides an opportunity to cancel the removal operation, modify the request parameters, or perform custom validation before the files are actually removed from the server.

Constructors

BeforeRemoveEventArgs()

Declaration

public BeforeRemoveEventArgs()

Properties

Cancel

Gets or sets a value indicating whether the file removal action has been canceled.

Declaration

public bool Cancel { get; set; }

Property Value

Type	Description
System.Boolean	true to cancel the file removal operation; otherwise, false.

Remarks

Setting this property to true will prevent the file removal operation from proceeding. This allows for conditional removal based on custom logic or user confirmation.

CurrentRequest

Gets or sets the XMLHttpRequest instance associated with the file removal operation.

Declaration

public object CurrentRequest { get; set; }

Property Value

Type	Description
System.Object	An object containing XMLHttpRequest details, or null if no request is associated.

Remarks

This property provides access to the underlying HTTP request object that will be used for the file removal operation. It allows for customization of request headers, authentication, and other HTTP-specific settings before the removal request is sent to the server.

CustomFormData

Gets or sets additional custom data in key-value pair format to be submitted with the removal request.

Declaration

public object CustomFormData { get; set; }

Property Value

Type	Description
System.Object	An object containing key-value pairs of additional data, or null if no custom data is provided.

Remarks

This property allows developers to include additional parameters or metadata with the file removal request. Common uses include authentication tokens, user identifiers, or other application-specific data required by the server-side removal handler.

FilesData

Gets or sets the list of file details that will be removed from the server.

Declaration

public List<FileInfo> FilesData { get; set; }

Property Value

Type	Description
System.Collections.Generic.List<FileInfo>	A System.Collections.Generic.List<> containing the details of files to be removed, or null if no files are specified.

Remarks

This property contains information about all files that are scheduled for removal, including file names, sizes, and other metadata. This information can be used for logging, validation, or displaying confirmation messages to users before removal.

PostRawFile

Gets or sets a value indicating whether the selected raw file data should be sent to the server during removal.

Declaration

public bool PostRawFile { get; set; }

Property Value

Type	Description
System.Boolean	true to send the raw file data to the server; otherwise, false. The default is true.

Remarks

When set to true, the complete file information including binary data is sent to the server. When set to false, only the file metadata (such as filename and size) is sent. Setting this to false can improve performance when only file identification is needed for removal operations.
