Documentation:Upload/Download files and images in MDriven Turnkey

Upload/Download files

To upload files into your Turnkey application you should create an attribute with type of Blob.

You can set it in the properties area in MDriven Designer.

MDriven Turnkey will render Blob as the upload button component. Text inside the button depends on your ViewColumn name. Don't forget to use <MyColumn>_FileName and <MyColumn>_ContentType to save your name and content type of the uploaded file.

When you upload your file you will see the progress bar inside the button which will indicate uploading percentage. When uploading is done the button will turn into the green color and file name will place under the button.
