I think I'm going mad - this seemed like an easy thing to do but I can't find any info on it at all.
I have created a Custom List and added 4 columns to it. Created By and Modified By are already in the list but hidden from the view.
I want to add a Date Modified column (which is a built in field) to this Custom List. How do I do this programmatically?
Are you trying to add the column to the list or to a view? The Date Modified column should be added to the list by default. To add it to the view (i.e. so it shows up when you navigate to the list) you can use code similar to the following:
using (SPWeb web = new SPSite("http://intranet/").OpenWeb())
{
SPList customList = web.Lists["CustomList"];
SPView defaultView = customList.DefaultView;
defaultView.ViewFields.Add("Modified");
defaultView.Update();
}
With sharepoint sometimes you must do ugly things... stuff you would not want your children know when they grow up.
Here is a pitifull solution:
- you create a DateTime field just like any other.
- you create a workflow when data changes, workflow starts, updates that your custom modified field and then stops.
ANYWAY, I know it is possible to show the default Modified field, perhaps you wanna go in that direction a little bit more.

We use Sharepoint Services 3.0 as a project tracking tool. We have a list set up that contains your basic information (description, etc.) plus we have a "assigned person" column that is of type Person or Group that we use to associate list items with individuals. This column supports multiple selections.
We would like to set up alerts such that each person gets an alert email only if they are assigned to a list item. The approach we have taken is to set up a view on this list that is filtered to show list items where the assigned person equals [Me], and then to create an alert on this list that is set to send an email when someone changes an items that appears in the view.
This works well when there is only one person in the assigned person column. It does not work when there is more than one person in the assigned person column.
Does anybody know why this wouldn't work, or what I can do to troubleshoot? Is there a better way to achieve the end result? We could make several "assigned person" columns and not allow multiple selections, but that seems kind of kludgy.
Try this info site,
http://www.sharepointalert.info
it has a good alert trouble shooting guide.
The reason it works for one person but not multiple people is because the check is specifically against an individual. The comparison your view does is whether Assigned is equal to [Me], not if Assigned has [Me] as one of its entities.
Instead of using a list filter of is equal to, use the list filter contains. That should do the trick.
EDIT IN RESPONSE TO COMMENTS
To access the object model, you'll need to use Visual Studio. I'm unaware of a method to accomplish this kind of thing using SharePoint Designer, but maybe there's some sort of crazy Datasheet View thing you can do. Anyway... onto your actual needs...
The following code sample illustrates a very basic method for achieving your goal.
using (SPSite site = new SPSite("yourwebsiteurlhere"))
{
using (SPWeb web = site.OpenWeb())
{
SPList list = web.Lists["titleoflist"];
SPView view = list.Views["filteredviewname"];
view.Query = "<Where><Contains><FieldRef Name=\"assignfield\"/><Value Type=\"Integer\"><UserID Type=\"Integer\" /></Value></Contains></Where>";
view.Update();
}
}
Replace "yourwebsiteurlhere" with the website url, "titleoflist" with the title of your list in question, "filteredviewname" with the name of the view, and "assignfield" with the internal name that you used for your assignment field. If you created it through the standard SharePoint UI, this should be the name of the field without any spaces.
As far as where to run the code, you could put this kind of thing in a one-time workflow. I sometimes do that just to make sure I have necessary privileges. Hope this helps!
If you're not able to/allowed to use Visual Studio, then your solution will probably have to be to look into a 3rd party solution.
I'm working on a SharePoint publishing site and I want to "log" all the changes made by users in a SharePoint list.
Some searches on the web guided me to the EventReceiver.
But my EventReceiver must be generic and attached to all lists in the site collection. The "log list" has several columns like the name of the list in which the event occurred, the name of the modified item, its old value and its new value.
Can someone guides me on how to achieve this?
There's already a provided answer for you on StackOverflow, hurrayy!!
It sounds possible. Create a class that inherits from SPItemEventReceiver and override ItemUpdating. You can use the following code to get the list:
using (SPWeb web = properties.OpenWeb())
{
SPList list = web.Lists[properties.ListId];
}
You can then use list to grab the list's title and URL. Next, compare each DictionaryEntry entry in properties.AfterProperties to the corresponding value in properties.ListItem to get your differences. Then save it to your log list. The trick would be automatically attaching your Event Receiver to each newly created list. Perhaps a timer job would work.
That said...
Before trying any of that, go to your site collection's Site Settings. Under Site Collection Administration, click Site collection audit settings. Under Specify the Document and Item events to audit, check Editing items. Only go with a custom solution if that does not give you what you need.
Would Version history not achieve the same functionality?
You can see what fields were changed by who and when. Though you would have to look at a list by list basis.
You can also access the version history information via the object model if you want to generate reports web part.
Otherwise using Janis Veinbergs link on how to attach a event handler to all lists and Rich Bennema method of getting the values from the updated item in a generic way, though I would use ItemUpdated as you don’t want to change the data that was updated only copy it to another location so there is no need to catch the data before it is submitted to the SharePoint database
I have a SharePoint site that's being created from a custom site definition. The site definition has the following Features:
A custom content type.
A custom list template whose schema.xml file refers to that content type.
A list instance feature which refers to my above list template feature.
During the site provisioning process, I activate each of these features (each is at the SPWeb level) through C# code in the order above. My resulting site looks as I expect and seems to work fine, but it has the weird artifact that the "all site content" page for my site shows my custom list twice.
My list acts okay -- its item receivers fire correctly and only once. In SharePoint Manager (SPM), I also see the list show up twice, and when I expand the tree to look at the attributes, they appear identical across the two lists (even the list items inside the lists). I suspect that I may be fooling myself and SPM might be just looking at the same list twice, while some actual rogue list lies in the dark shadows of my site.
So, what could have gone wrong here? How could I have created multiple lists of the same name? How can I correctly create this list? And how can I properly clean up the weirdness in existing sites that exhibit this behavior?
Edit:
In response to Michael Stum's question, I created this console app to loop through the site's lists and get the ID:
using (SPSite site = new SPSite("http://myserver/projects/myproject"))
{
using (SPWeb web = site.OpenWeb())
{
var lists = web.Lists;
foreach (SPList list in lists)
{
Console.WriteLine(list.ID + ": " + list.Title);
}
}
}
This code shows my list twice -- same title, same ID.
Another edit:
I looked in the SharePoint content database for this site, and I executed this query:
SELECT * FROM AllLists where tp_webid = '<my SPWeb guid>'
This reveals that there's only one actual list with the title and GUID that I retrieved from my C# code above. So what is causing these multiple entries to show up when I'm browsing through my site?
I've come across with this issue several times. It's not a bug, most likely you have semantic errors in the elements.xml of your list template.
If a list definition contains more than one default view, the symptoms you described above will show up. Check the elements.xml file of your list template and make sure you don't have more than one View-Element with in it.
Kind regards

I suggest you put a call in to Microsoft, this sounds like a bug.
P.S. without seeing the actual solution that creates the list we can't determine what's happening, perhaps a feature got activated twice...
Today I came across this issue and after reading the above answers I came up with an easy solution. Just create a new Default view and the Document library will show up normally again.
Kind regards,
Thijmen Groenewegen
P.s
I "created" the same two libraries by migrating the library from one place to another. At the old place the library was only showed once. If I look at the default views on that library two views are checked as Default.
Groenewegen is spot on.
I ended up with two Announcements lists on a site after I ran Export-SPWeb on a subsite and then Import-SPWeb to move it to a new site collection.
To fix it, I created a new default view for the list, All List Items, selected one of the two All Items views and deleted it, and the issue was fixed.
The Announcements list was being displayed twice on the View All Site Content page, and the data was being shown twice when viewing the All Items page.
Also, an intermediate step that you have to take before creating a new default view, is to open the list or library and add "?contents=1" to the URL so you can open the web part maintenance page and "Close" one of the duplicates. You have to do this because the web part ribbon will not show up on the Announcements page if multiple web parts exist, and you need the ribbon to access the view drop down and create a new view.
Have you tried with:
list.RootFolder.Name
(which shows the "internal" name - a part of the url)
list.Title shows the displayname (which can appear twice or more).
This could also be the explanation why you get multiple lists. You have maybe added them with the same displayname but dirrerent "internal" names?
I've got a requirement to hold a DateTime value in a SharePoint field but to customise the display in a list view so that it shows as a mmmm string. The underlying value must remain as the DateTime so the sort is chronological rather than alphabetical.
So I think that a Custom Field is the way to go, I'll also get some added benefit in restricting the user interface to a month picker so even if there is another solution I'll likely go down this route to get that.
I've read that I can apply custom templates to the new, edit and display actions but I can't seem to find anything saying how to alter the list view (display patterns doesn't seem to be enough).
Anyone got any ideas?
Thanks
Justin
I dont know if this is what you are looking for but I have used a solution with a custom fieldcontrol that overrides RenderFieldForDisplay like:
protected override void RenderFieldForDisplay(HtmlTextWriter output)
This is a similar post:
How to manage column based access control in Sharepoint lists?
Ended up using a bit of an ugly series of <IfSubString> within the RenderPattern...
I'm looking to add a new field onto my NewForm.aspx, EditForm.aspx and DispForm.aspx pages in Sharepoint Designer 2007. I've managed to add a new textbox webpart and have edited the Common Textbox Tasks to make the Data Field my new field (Contacts..)
But how do I edit Edit.aspx and DispForm.aspx to display this new field?
I've looked around already answered questions on the site but I haven't run across what I'm really looking for -- sorry if I missed it!
Thanks!

It doesn't count as "development", but wouldn't creating a new List column, Site Column or Content Type add this additional field to all your list forms just fine? How does this not work in your particular case?
You have to use SharePoint Designer to access the site and edit those aspx (in the 'Forms' subfolder of the folder named after the list)
You are probably going about this the wrong way. You should not need to change the edit and new forms for a list just because you want a new field. You do need to add the field to the underlying list and rely on the code in the forms to display the field correctly.
IN SPD choose the Table tab on the far right, then Select a row, then you can Insert Above or Insert Below, then you can add your new field.
New item, edit, and display forms aren't attached to lists so much as they attached to content types. If you can't use InfoPath or Designer to set these up, what you do is the following:
Create the form in question as an application page. For whatever reason, SharePoint application pages won't render on-screen, so to get an idea of what I'm looking at I generally make them in a visual web part or separate ASP application first, then copy and paste the ASP/HTML over, then delete the original.
In the case of edit and display forms, SP will pass you a query string with the ID in it. I capture the item in question thusly:
NameValueCollection nvQueryString = Page.Request.QueryString;
taskID = Convert.ToInt32(nvQueryString["ID"]);
ViewState["TaskID"] = taskID;
SPWeb thisWeb = SPContext.Current.Web;
SPList taskList = thisWeb.Lists["Job Request approval tasks"];
SPListItem taskItem = taskList.GetItemById(taskID);
After adding on whatever it is you need to add on, you do need to add logic to the .cs page or a separate class that actually edits/adds the item in question. Probably pretty obvious...
From here you have three options: either create an event receiver that points the editformURL/displayformURL/newformURL of the content type in question to your application page, create a brand new content type and add the URL for your application page in its XML definition, or add it manually via Powershell.
