Workflow is not triggering when the sharepoint list item is updated programmatically

Question

I am using the following code to update the list item and trigger the workflow. But the workflow is not triggering when the item is updated. Any thoughts on this.

 using (SPSite site = new SPSite("http://spweb02:91/test"))
                {
                    using (SPWeb web = site.OpenWeb())
                    {


                        SPUserToken tokentemp = web.SiteUsers[@"i:0#.w|testdomain\" + "gs-test-r"].UserToken;


                        using (SPSite sitetemp = new SPSite("http://spweb02:91/test", tokentemp))
                        {
                            using (SPWeb webtemp = sitetemp.OpenWeb())
                            {

                                try
                                {
                                    sitetemp.AllowUnsafeUpdates = true;
                                    webtemp.AllowUnsafeUpdates = true; 
                                    SPList parentlist = webtemp.Lists["Test"];
                                    SPListItem parent = parentlist.Items[0];
                                    parent["Title"] = DateTime.Now.ToString();                           

                                    parent.Update();
                                    webtemp.AllowUnsafeUpdates = false;
                                    sitetemp.AllowUnsafeUpdates = false;

                                }
                                catch (Exception ex)
                                {


                                }
                            }
                        }
                    }
                }

Updates to items made by the system account will never fire a workflow. Is this the case here? — Morten K

It is not system account, I am using the normal user account as mentioned in the code but still the workflow is not triggering. — user17274

Ok that wasn't clear to me if it was a system account. I afraid I won't be of much help then. The only thing I can add is if you choose to use Jquery I have a working example that's triggering the workfloow on the newly created item. — Morten K

Actually the workflow has to be triggered when the item is updated pro-grammatically. Users are not updating the items from UI. — user17274

Then you have to make sure that whatever user as triggering the workflow isn't considered a system account. It doesn't matter if a user is updating an item from the UI or for Access for instance (Since it runs under the user credentials) — Morten K

Run the following code after SPListItem.Update().

SPSite.WorkflowManager.Dispose();

For example:

using(SPSite site = new SPSite(url))
{
    using(SPWeb web = site.OpenWeb())
    {
        SPList list = web.GetList(url);
        SPListItem item = list.Items[1];
        item[updateField] = DateTime.Now.ToLongDateString();
        item.Update();
        site.WorkflowManager.Dispose();
    }
}

Refer to:
