Upload

Component for uploading files in Universal Dashboard.
The UDUpload component is used to upload files to Universal Dashboard. You can process files the user uploads. You will receive the data for the file, a file name and the type of file if it can be determined by the web browser.
This component works with UDForm and UDStepper.

Uploading a File

Uploads a file and shows the contents via a toast.
New-UDUpload -OnUpload {
Show-UDToast $Body
} -Text 'Upload'
The body of the OnUpload script block is a JSON string with the following format.
{
data: "base64 encoded string of data",
name: "file name of the file uploaded",
type: "file type as determined by the browser"
}
The $EventData is an object with the following structure.
public class Upload
{
public string Name { get; set; }
public string FileName { get; set; }
public DateTime TimeStamp { get; set; }
public string ContentType { get; set; }
public string Type => ContentType;
}

Uploading a File with a Form

Uploads a file as part of a UDForm.
New-UDForm -Content {
New-UDUpload -Id 'myFile' -Text 'Upload File'
} -OnSubmit {
Show-UDToast $Body
}
The body of the OnSubmit script block is the same one you will see with any form and the file will be contains as one of the fields within the form.

Example: Uploading a file and save to it the temp directory

This example allows a user to upload a file. Once the file is uploaded, it will be saved to the temporary directory.
New-UDUpload -Text 'Upload Image' -OnUpload {
$Data = $Body | ConvertFrom-Json
$bytes = [System.Convert]::FromBase64String($Data.Data)
[System.IO.File]::WriteAllBytes("$env:temp\$($Data.Name)", $bytes)
}
