Question

我为每个分配给用户的角色创建任务。每个角色都有几个资源。我需要为每个资源向Workflow自定义任务表单添加动态组合框。组合框将包含所有帐户。这可以通过自定义的infopath任务表单来实现吗？

甚至可以在infopath任务表单中添加代码（是否需要管理员批准）？

Answer 1

可以将代码添加到自定义InfoPath任务表单。应该确保将dll与表单一起部署。

还可以在重复表中添加组合框（所有组合框都具有相同的数据源）。重复表的行在PageLoad上创建，其数据由Workflow提供，方法是将其作为XML嵌入到表单字段中。

    public void InternalStartup()
    {
        EventManager.FormEvents.Loading += new LoadingEventHandler(FormEvents_Loading);
    }

    public void FormEvents_Loading(object sender, LoadingEventArgs e)
    {
        string myNamespace = NamespaceManager.LookupNamespace("my");

        XPathNavigator repTable = MainDataSource.CreateNavigator().SelectSingleNode("/my:RoleAssigmentExecution/my:Resources", NamespaceManager);
        if (repTable == null)
        {
            XPathNavigator node = MainDataSource.CreateNavigator().SelectSingleNode("/my:RoleAssigmentExecution", NamespaceManager);
            using (XmlWriter writer = node.AppendChild())
            {
                writer.WriteStartElement("Resources", myNamespace);
                writer.WriteEndElement();
                writer.Close();
            }

        }
        repTable = MainDataSource.CreateNavigator().SelectSingleNode("/my:RoleAssigmentExecution/my:Resources", NamespaceManager);
        if (repTable != null)
        {
            using (XmlWriter writer = repTable.AppendChild())
            {

                XPathNavigator inst = MainDataSource.CreateNavigator().SelectSingleNode("/my:RoleAssigmentExecution/my:Instructions", NamespaceManager);
                writer.WriteStartElement("ResorceAccounts", myNamespace);
                writer.WriteElementString("resource", myNamespace, inst.Value);
                writer.WriteElementString("accountCombo", myNamespace, "");
                writer.WriteEndElement();

                writer.Close();
            }
        }
        else 
        {
            string path = "/my:RoleAssigmentExecution/my:Remarks";
            XPathNavigator node = MainDataSource.CreateNavigator().SelectSingleNode(path, NamespaceManager);
            node.SetValue("can not access Repeating Table");
        }
    }
