HttpContext & SPContext is always null when Uploading Multiple document libraryin sharepoint : I'm tring to get a value from the session and update a custom field when uploading multiple documents to my sharepoint document library.
I faced an issue when I was tring to update some custom fields of my document library when uploading multiple documents, the field was ( ProjectID ) which I put it inside a session in my custom webpart (the step before uploading the documents).
What I did is : I put the projectID into the cache ( per user which acts as a session) inside the custom webpart as follows :
if (Request.QueryString["ProjectID"] != null)
HttpRuntime.Cache.Add(SPContext.Current.Web.CurrentUser.LoginName, ProjectID, null, DateTime.UtcNow.AddMinutes(60), System.Web.Caching.Cache.NoSlidingExpiration, System.Web.Caching.CacheItemPriority.Normal, null);
then I implemented the ItemAdded event and I get the value of the cached projectId through :
Note that I get the cached key through the created by field which is the same key name that I cached it from inside my custom webpart.
public override void ItemAdded(SPItemEventProperties properties)
string ProjID = "";
string CreatedBy = null;
if (properties.ListItem["Created By"] != null)
CreatedBy = properties.ListItem["Created By"].ToString().Split(';').Replace("#","");
if (HttpRuntime.Cache[CreatedBy] != null)
ProjID = HttpRuntime.Cache[CreatedBy].ToString();
if (properties.ListItem["Project"] == null)
properties.ListItem["Project"] = new SPFieldLookupValue(ProjID);
catch (Exception ex)
