# [Upload Version Button Component (Workaround)](../../../lib/content-services/src/lib/upload/components/upload-version-button.component.ts "Defined in upload-version-button.component.ts")
|
|
|
|
Activates a file version upload.
|
|
|
|
Until further backend API improvements are implemented, this component is meant to be used
|
|
to enrich the features and decrease the restrictions currently applied to node version uploading.
|
|
|
|
## Basic usage
|
|
|
|
```html
|
|
<adf-upload-version-button
|
|
staticTitle="Upload new version"
|
|
[node]="node"
|
|
[rootFolderId]="node.parentId"
|
|
[versioning]="true"
|
|
(success)="onUploadSuccess($event)"
|
|
(error)="onUploadError($event)">
|
|
</adf-upload-version-button>
|
|
```
|
|
|

## Details
|
|
|
|
This component extends the [Upload Button component](upload-button.component.md). The
|
|
properties and events are the same except for the `node` property that specifies the node
|
|
to be versioned (this is a _required_ input parameter). However, some properties don't make
|
|
sense when applied to the [Upload Version Button component](upload-version-button.component.md) so they are simply ignored.
