Changing Document Property Value in Before Save

API Questions

Hello,

I would like to see an example for changing document property value in the Before save event.

Could any one help me on this.

This is what I am currently doing and it is not getting the desired result.

using System;
using umbraco.BusinessLogic;
using umbraco.cms.businesslogic.web;
using Examine;

public class UmbracoEvents: ApplicationBase
{
/// <summary>Constructor</summary>
public UmbracoEvents()
{
Document.BeforeSave += new Document.SaveEventHandler(Document_BeforeSave);
}

private void Document_BeforeSave(Document sender, umbraco.cms.businesslogic.SaveEventArgs e)
{
if (sender.ContentType.Alias == "Article")
{
if(sender.getProperty("articleDate").Value.ToString().Trim().Length>0)
{
if(sender.getProperty("expiryDate").Value.ToString().Trim().Length==0)
{

DateTime startDate= (DateTime)sender.getProperty("articleDate").Value ;
sender.getProperty("expiryDate").Value = startDate.AddMonths(12).AddDays(-1);
sender.Save();
}
}
}
}
}

Any help on this will be appreciated.

thanks,

Rajeev

Hi Rajeev,

Have you had a look at Richard Soetemans blog about it? :)

http://www.richardsoeteman.net/PermaLink,guid,f470b6cf-40da-4aa9-a0d9-7b984fe9bf59.aspx

Just out of curiousity: what is the result (if there is any) do you get from your code?

Hi Bo,

Thank you for the udpate. I will look in to the blog.

Nothing happening for now in save. I am not sure about if any mistakes in the code or any restriction for doing that.

Thanks,

Rajeev

Hi Rajeev,

Have you tried to simply add something to the umbraco log table in the event? Just to see if the event actually fires :)
```
umbraco.BusinessLogic.Log.Add(logtype, nodeid, comment);
```

Hi Bo,

Apologies for the delay in updating as I was on something else, I have tried logging into the table.

Actually in the Before Save event getProperty is not giving the values as desired.

I am getting the values in the after save event and I am changing the values there now. Is there a way to refresh the UI in the event. The changes are visible only after reloading the nodes. Not sure if this is the right approach. Thank you again.

This is the working code:

Document.AfterSave += new Document.SaveEventHandler(Document_AfterSave);

private void Document_AfterSave(Document sender, umbraco.cms.businesslogic.SaveEventArgs e)
{
    if (sender.ContentType.Alias == "Article")
    {
    Log.Add(LogTypes.Custom, sender.Id, "After Save Event raised");
    if(sender.getProperty("articleDate").Value.ToString().Trim().Length>0 && sender.getProperty("expiryDate").Value.ToString().Trim().Length==0)
       {
        DateTime articleDate=Convert.ToDateTime(sender.getProperty("articleDate").Value.ToString());
        sender.getProperty("expiryDate").Value = articleDate.AddMonths(12).AddDays(-1);
        sender.Save();
       }
    }
}

Thank you Again.
