Hi All,
I am having issues when Updating an item field of a list in SharePoint 2013 site from a visual webpart in a different site collection. Posted the code below.
I am the administrator for both the site but I added elevated rights so user can update items.
The problem is when I deploy and run the code there is no error. But the field is not updating.
When I add "itemToUpdate.Update();" after setting the field , I get "Object reference not set to an instance of an object" . I have posted the exception below as well.
Am I missing anything ??? Any help is much appreciated. Thank you in advance.
private void setReviewStatus()
{
SPSecurity.RunWithElevatedPrivileges(delegate()
{
string strURL = string.Empty;
int listItemId;
using (SPSite oSPsite = new SPSite("XXXX"))
{
using (SPWeb oSPWeb = oSPsite.OpenWeb())
{
oSPWeb.AllowUnsafeUpdates = true;
// Fetch the List
SPList Employeelist = oSPWeb.Lists["Employee"];
foreach (SPListItem item in Employeelist.Items)
{
try
{
SPFieldUrlValue lnkFieldUrlValueurl = new SPFieldUrlValue(item[EmployeeFieldNameAndReviewStates.strURLField].ToString());
strURL = lnkFieldUrlValueurl.Url.ToString();
}
catch (Exception ex)
{
}
if (!string.IsNullOrEmpty(strURL.ToString()))
{
if (strURL == getCurrentSiteURL())
{
try
{
listItemId = item.ID;
SPListItem itemToUpdate
= Employeelist.GetItemById(listItemId);
itemToUpdate["Employee Number"] = "458XXX8687";
Employeelist.Update();
oSPWeb.AllowUnsafeUpdates
= false;
}
catch (SPAlertUpdateException ex)
{
}
break;
}
}
}
}
}
});
}
