Hmm bit confused now, I've looked up the property delete in the Umbraco source:

foreach (cms.businesslogic.property.Property p in this.getProperties)
                    if (p.PropertyType.DataTypeDefinition.DataType.Id == uploadField.Id &&
                        p.Value.ToString() != "" &&
                        System.IO.File.Exists(System.Web.HttpContext.Current.Server.MapPath(p.Value.ToString()))
                        )
                    {

                        System.IO.File.Delete(System.Web.HttpContext.Current.Server.MapPath(p.Value.ToString()));

From which I created my code to this:

if (System.IO.File.Exists(System.Web.HttpContext.Current.Server.MapPath(ddlDocList.SelectedValue.ToString())))
        {
            System.IO.File.Delete(System.Web.HttpContext.Current.Server.MapPath(ddlDocList.SelectedValue.ToString()));
        }   

However this does not seem to do anything at all.

Any help?

Cos the file didn't exist, duh!, Anyway I updated the code to this:

string docPath = Server.MapPath("/media/" + ddlDocList.SelectedValue + "/" + ddlDocList.SelectedItem.ToString());

        if (System.IO.File.Exists(docPath))
        {
            System.IO.File.Delete(docPath);
        }             

        string docName = ddlDocList.SelectedItem.ToString();

        messages.Text = "The document <i>" + docName + "</i> was deleted successfully.";
        umbraco.library.RefreshContent();

Which successfully removes the file from the file system, of course, but the filename remains on the media content. I tried p.delete on the property, but that appeared to delete the property node and caused a problem with that media. 

Still not working :(

if (System.IO.File.Exists(docPath))
        {
            System.IO.File.Delete(docPath);
            Media m = new Media(Convert.ToInt32(HttpContext.Current.Session["nodeid"]));
            m.getProperty(HttpContext.Current.Session["property"].ToString()).Value = String.Empty;
            umbraco.library.UpdateDocumentCache(m.Id);            
        }   

Darryl,

Whats the exception? (If any)

Chris

Working now Chris, thanks for your response. Here's the code I managed to get it working with:

if (System.IO.File.Exists(docPath))
        {
            System.IO.File.Delete(docPath);            
            Media m = new Media(Convert.ToInt32(ddlDocList.SelectedValue));

            nodeId = Convert.ToInt32(HttpContext.Current.Session["nodeid"]);

            if (nodeId == 1303 || nodeId == 1740 || nodeId == 1745 || nodeId == 1183 || nodeId == 1752)
            {
                m.delete();
            }
            else
            {
                m.getProperty(HttpContext.Current.Session["property"].ToString()).Value = String.Empty;
                m.Save();
            }
            m.XmlGenerate(new System.Xml.XmlDocument());           
        }

Darryl,

Not sure if you have multiple environments, if you do be careful the nodeId's in your if statement remain constant.

We use courier here, so the nodeId's on the production box do not match that of the dev box.

Thanks,

Chris.

Thanks for the advice. They are the same fortunately. The reason for the programmatic deletion is we do not give the users access to the Umbraco back-end.

is working on a reply...
