Kurniawan,

I have created one for a page title its same principle, when you publish a page it will check all other published pages to ensure that the page title for the current page is unique.

I am going to release it at some point when i get 5 minutes

Is umbraco has a GUID data type like in .NET?

Can we generate incremental ID (int) in umbraco?

Thanks

We often have a requirement to utilise a completely unique ID on a document type. 

Thinking of the most recent example, we want to generate a unique ID to syndicate content to a remote source.

We chose to achieve this by creating a label (read only) data type on the document and then using a dcoument event handler to generate a GUID on the first save of the document.

The unique ID is in the format below and is guaranteed unique to some silly order by Microsoft :)

The document event handler is a file that stis in the app_code directory, here's a quick example of how we achieve this:

if (sender.ContentType.Alias == "mkNewsItem")
            {

                string stGuid = sender.getProperty("mkNewsGUID").Value.ToString();


                if ( String.IsNullOrEmpty(stGuid) ){               
                    sender.getProperty("mkNewsGUID").Value = System.Guid.NewGuid().ToString();
                    Log.Add(LogTypes.Save, sender.Id, "Generated GUID for news item");
                }
            }

Hope this helps - if you need more info - get in touch :)

Good Luck,
David :)
