SharePoint 2013 Designer Workflow does not resumes

Question

I have a SharePoint 2013 designer workflow. it has an action "Wait for Item Update". Workflow does not resumes when i update the item through Code(C#) but when item is updated from out of the box edit form it resumes.

SPList listUpdate = web.Lists["Registration"]; SPListItemCollection items = listUpdate.GetItems(new SPQuery() { Query = @"" + Convert.ToString(newItemid) + "" }); web.AllowUnsafeUpdates = true; items[0]["Title"] = "1"; items[0].Update(); web.AllowUnsafeUpdates = false;

Answer 1

Without seeing your code, one wonders if you executed the query?

class UpdateListItem
{
    static void Main()
    {   
        string siteUrl = "http://MyServer/sites/MySiteCollection";

        ClientContext clientContext = new ClientContext(siteUrl);
        SP.List oList = clientContext.Web.Lists.GetByTitle("Announcements");
        ListItem oListItem = oList.Items.GetById(3);

        oListItem["Title"] = "My Updated Title.";

        oListItem.Update();

        clientContext.ExecuteQuery(); 
    }
}
