    Hi,
    For this, we need to override the OnModifiedDocument method for SupportApi and save the document at the required place. We also need to add the custom save button to save the changes on the server and load the PDF from server.

    Please refer to the attached sample for reference.

    Hi Patrick,
    With reference to the following demo sample:
    https://www.grapecity.com/documents-api-pdfviewer/demos/ui-customization/save-changes/purejs

    The following code should be avoid:
    // viewer.toolbarLayout.viewer.default.splice(0, 0, 'download');
    // viewer.toolbarLayout.viewer.mobile.splice(0, 0, 'download');

    var annotationEditorButtons = ['custom-save', 'edit-select', 'edit-sign-tool', '$split', 'edit-text', 'edit-free-text', 'edit-ink', 'edit-square',
    'edit-circle', 'edit-line', 'edit-polyline', 'edit-polygon', 'edit-stamp', 'edit-link',
    '$split', 'edit-redact', 'edit-redact-apply', 'edit-erase', '$split', 'new-document', '$split', 'new-page', 'delete-page'];



    In the same way, you may customize the layouts as per your need.

    Hi Patrick,
    As we understand, you would like to save the modified document in the localstorage on a button click. You would not like to save the PDF in the client machine.

    If yes, please refer to the following demo sample:
    https://www.grapecity.com/documents-api-pdfviewer/demos/ui-customization/save-changes/purejs

    In the sample, the custom save button saves the modified document and load in the PDFViewer the updated document. On completing the updated document load, you may call the localstorage API to save the PDF on client localstorage.

    Hope it helps!

    Hi thanks for the reply.
    I tested the sample and it works fine as expected.
    is there any sample code for Support API with ASP.NET web forms.
    I need to implement this in very old project but still running using ASP.Net framework 4.5.
    Please give some advise.
    Thanks

    Hi Patrick,
    The SupportApi is dependent on GcPdf which supports NETFramework >=4.6.1. So please upgrade the NetFramework to 4.6.1 if possible.


    The Framework up-gradation may work for you correctly.
