Image Gallery - Overwrite existing image during upload? - Sitefinity - General Discussions

Posted by Community Admin on 14-Feb-2011 00:00

I understand that Sitefinity will store images in the database, so upon upload an image is assigned a GUID and is no longer unique identified by name. However, users of the system are expecting that when they upload a file with a name that already exists in the gallery they uploading to they will be prompted to overwrite the existing file. Is there somehow to set this as an option for the Image Gallery module, or is this functionality not supported?

Hi Anthony,

There is a replace image button when you are editing a widget, which lets you reupload the image. Please refer to attached screen shot.

Hi,

May be you would have found a solution for this. But, here's a custom library provider that helps you overwrite the documents.
Note: This is for documents library only. You can modify this for image provider.

using System;

using System.Reflection;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Diagnostics;

using Telerik.Sitefinity.Fluent;

using Telerik.Sitefinity;

namespace SitefinityWebApp.Custom

public class LibraryProvider : Telerik.Sitefinity.Modules.Libraries.Data.OpenAccessLibrariesProvider

public LibraryProvider() : base()

/// <summary>

/// </summary>

/// <param name="content"></param>

/// <param name="source"></param>

/// <param name="extension"></param>

public override void Upload(Telerik.Sitefinity.Libraries.Model.MediaContent content, System.IO.Stream source, string extension)

if (content is Telerik.Sitefinity.Libraries.Model.Document)

DocumentOverwrite(content, source, extension);

else

base.Upload(content, source, extension);

private void DocumentOverwrite(Telerik.Sitefinity.Libraries.Model.MediaContent content, System.IO.Stream source, string extension)

var masterId = GetMasterId(content, extension);

if (masterId.HasValue)

Publish(masterId.Value, source, extension);

//Get master doc

var master = GetDocument(masterId.Value);

//Delete new content

Delete((Telerik.Sitefinity.Libraries.Model.Document)content);

//Overwrite

content = master;

else

base.Upload(content, source, extension);

private void Publish(Guid masterId, System.IO.Stream source, string extension)

var manager = Telerik.Sitefinity.Modules.Libraries.LibrariesManager.GetManager();

var master = manager.GetDocument(masterId);

//Create draft version of master

var temp = (Telerik.Sitefinity.Libraries.Model.MediaContent)manager.Lifecycle.CheckOut(master);

//Upload file into draft

base.UploadDataOnly(temp, source);

//Check in draft, updates master

manager.Lifecycle.CheckIn(temp);

//Publish

manager.Lifecycle.Publish(master);

private Guid? GetMasterId(Telerik.Sitefinity.Libraries.Model.MediaContent content, string extension)

Guid? id = null;

Telerik.Sitefinity.Libraries.Model.Document master = null;

using (var fluent = App.WorkWith())

master = fluent

.DocumentLibrary(content.Parent.Id)

.Documents()

.Get()

.Where(doc => doc.Status == Telerik.Sitefinity.GenericContent.Model.ContentLifecycleStatus.Master)

.ToList()

.FirstOrDefault(

doc =>

doc.Title == content.Title

&& doc.Extension == extension

&& doc.Id != content.Id);

if (master != null)

id = master.Id;

return id;

Not sure why, but this request has been in for many years now yet sitefinity has not implemented a solution.

Hope this helps.
Thanks,
