Open SharePoint list item attachment in view mode

Question

Wanted to open list item attachments in View Mode in browser.

"<SiteURL>/Lists/<ListName>/Attachments/<ListID>/<filename>?web=1&action=View" is opening the document in edit mode only even though action=View is appended to the query.

Is there any parameter that helps in opening the attachments in View mode in browser?

Hi @Varghese, Ajith (Cognizant),

Thank you for posting in this community.

It seems, you would like to make the attachment in SharePoint list as Read-only mode.

I understand that it would be more convenient if can open the attachment in Read-only mode. Unfortunately, there is no out of box feature to achieve the requirement at this moment.

We are always looking for ways to improve SharePoint, and your feedback and suggestions are very valuable. We suggest that you can make suggestions on this SharePoint Feedback portal for opening SharePoint list item attachment in view mode. Your contribution will be highly appreciated.

Meanwhile, after research a lot based on your requirement. Some users mentioned workaround by created a read-only document with custom workflow.

For your reference: Setting attachments to Read Only after upload to an item on a custom list

Please make sure that you completely understand the risk before retrieving any suggestions from the above link. 

In addition, I also found that creating a flow in Power Automate (Microsoft Flow) may be able to achieve this target. For your information: Set an item to read only in flow, attachment cannot be read anymore

I appreciate your understanding and stay safe!!

How can we get the SP list item attachment GUID using code?

Below URL will open the attachment in View mode. Wanted to know how we can get this DocGUID.

Hi @Varghese, Ajith (Cognizant),

Thank you for posting in this community.

Here’s a sample code snippet using JavaScript and the SharePoint REST API to get DocGUID:

// Get the list item by ID
var itemId = 1; // Replace with your item ID
var listTitle = "YourListTitle"; // Replace with your list title
$.ajax({
    url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getbytitle('" + listTitle + "')/items(" + itemId + ")/attachmentFiles",
    type: "GET",
    headers: { "Accept": "application/json; odata=verbose" },
    success: function(data) {
        var attachments = data.d.results;
        attachments.forEach(function(attachment) {
            console.log("Attachment Name: " + attachment.FileName);
            console.log("SourceDoc ID: " + attachment.UniqueId); // This is the sourcedoc ID
        });
    },
    error: function(error) {
        console.log("Error: " + JSON.stringify(error));
    }
});
