In my asp.net page I have a formview.  In the formview's InsertItemTemplate I declare a dropdown list as below:

                                    <asp:DropDownList ID="DropDownList6" runat="server" text='<%# Bind("District") %>'
                                    DataSourceID="SqlDataSource6" DataTextField="District"

Attach Workflow to Task List, don't get option to manually start workflow via dropdown on task item



I am running WSS 3.0 with other workflows which are functioning correctly.  I created a new workflow in Visual Studio 2008 and was able to successfully run it in my dev environment.  I attached the workflow to a task list in my dev environment and was able to manually start the workflow by using the drop down workflow option and using the menus to manually start it.  I installed this workflow in our production environment and attached it to the task list (which had a SPD workflow attached to it which stopped working about a month ago).  I made sure that the option to manually start the workflow was checked.  When I tried to manually start the workflow, (hover mouse over title, drop down) there isn’t a workflow option.  The workflow also will not start automatically when a task is changed.


I attached this same workflow to a different task list in production and get the option to start it.


I have tried creating a small workflow in SPD 2007 and attaching it to the task list.  It shows that it is attached, when I look at the workflows that are attached to the task list, but I still don’t get the option to manually start it.


I have checked my security and I have fu

Assigning users when creating a list item in a workflow


I'm using a workflow to assign tasks to users.  When I try to assign the task to a group (set in the workflow designer), the workflow gives me an error.  When I change the assign to property to a single user, the workflow works perfectly.  How do I get the workflow to assign the task to the group?  Or if that's not possible, can I get it to assign it to more than one user?

Concurrent update in sharepoint list item



How the concurrent for sharepoint list item are are handled.

if two or more users are working on same item. Then how sharepoint process multiple update request for particular list item.

link from one list item to another item in the same list?


I have a list in which it is possible for one item to be related to another list item in the same list.  I am trying make a column in the list which would contain a hyperlink to the related list item.  The primary column is called Bill Number, and the secondary column is Companion Bill Number .  The Companion Bill Number is the one I want to be a hyperlink to the list time in which that number is the primary Bill Number.  (hope that made sense!). 

I thought I could create a hypertext link out of the Companion Bill Number dynamically in a workflow action that runs on item creation.  I tried this by using the string builder to create a string for the hypertext link that I set to a workflow variable.  It looks like this  <a href="listURL.aspx?ID=[%Bill:CompanionBill%]">[%Bill:CompanionBill%].  Then in another action in the same workflow I tried to set the CompanionBill column to the variable value. 

What I ended up with was, instead of the number as a hyperlink, the text in the column reads as [%Bill:CompanionBill%].  I'm thinking this is failing because of the workflow process doesn't have the value of CompanionBill at the time I am asking it to set the variable value.

Any ideas on how I might make this dynamic link creation work?

When editing a list item the fields are not blank.


This is a recent issue that I have in which I have a "Issue Tracking" List that maintains the workflow of contract renewals.

When an person goes to edit an existing list entry, the description field (standard) has the original text in the box. Prior to this the original - or any older text from a prior change was listed outside and just below the box - and non editable.

That's not the case anylonger.

Any thoughts?

Update SharePoint List item using UpdateListItem web service with javascript

I'm using the Custom_AddListMenuItems function in a CEWP to add a menu item to each list item to Archive that item. This is achieved by updating a choice field in the item to 'Archived'. I'm trying to do this using the web service UpdateListItem web service to update the item using Javascript, but I can not find the correct code that updates the list item. I'm using this code:     var ctx=currentCtx;     var ciid=currentItemID;     var xmlHttp=null;     if (confirm("Are you sure you want to Archive this item?"))     {         var soapRequest = '<?xml version="1.0" encoding="utf-8"?>'+             '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">'+             '    <soap:Body>'+             '        <UpdateListItems xmlns="http://schemas.microsoft.com/sharepoint/soap/">'+
