I'm currently deploying a SharePoint solution with publishing pages. These pages allow the user to select "Do not update the modified-date".
This is solved by a small controll placed on the page.
<ctrl:ModifiedFieldManager FieldName="Modified" runat="server" id="modifiedmanager">
</ctrl:ModifiedFieldManager>
This control creates a checkbox the user can check or not.
If checked the modified field should stay the same.
The control derives from "BaseFieldControl".
public override void UpdateFieldValueInItem()
{
base.EnsureChildControls();
if (this.ModifiedFieldManagerBox.Checked)
{
this.Value = this.Item["Modified"];
base.UpdateFieldValueInItem();
}
else
{
this.Value = DateTime.Now;
}
}
The code above is responsible to write the "old" Modified-Date back to the item if checked.
The funny thing about this code is - it works if I'm logged in as admin.
As a normal user this code gets executed but the modified date is still the current date and time.
Could anyone give me some advice how to solve this for normal users?
Thx in Advance
Steve
Generally, you use SystemUpdate to ensure the modified fields are not changed on teh SPListItem

I want to prevent the user that he will loose his changes in an EditView when changing the view to another.
I use MVP4G in my project and the project is divided as mvp's structure (one package for the template another one for views ..) is there any solution to detect the EditView in the eventBus. or detect the current View shown to user
Thanks in advance
Thanks to the Navigation Event feature in mvp4g, the presenter will get control before the view changes. At this point the presenter can decide if the navigation will be done or not. This is the correct place in a mvp4g application to save your data.
First zu have to mark all events in the eventbus that will change your view with:
#Event(..., navigationEvent = true)
void goToPage1();
Next your presenters have to implement the NavigationConfirmationInterface and the requires confirm-method:
public class Presenter extends ... implements NavigationConfirmationInterface {
public void confirm(NavigationEventCommand event) {
//pseudo method to verify if the view has changed
if (isViewModified(){
//Window shouldn't be used inside a presenter
//this is just to give a simple example
if (Window.confirm("Are you sure you want to leave?")){
event.fireEvent();
}
} else {
event.fireEvent();
}
}
}
And the last thing to do, is to set the presenter of the current view to the confirmation presenter by calling:
event.fireEvent(false);
This is usually done when the presenter gets control.
You will find the documentation here:
https://github.com/FrankHossfeld/mvp4g/wiki/03.-Defining-EventBus#navigation-event
Thanks to MVP4G's team including El Hoss who gives me a hint to check the MVP4G's blog.. I've solved my problem by following this example

We have a solution that deploys a number of lists and pages. We wan't to create links for them on the Quick Launch menu automatically when a feature is activated.
The structure could be something like this.
Customers
Active
Inactive
Sales
Quotes
Orders
And so on. The site collection admin might add another link between the "Active" and "Inactive" links. When the feature is deactivated I don't want to remove the items, but if the feature is activated again i don't want the navigation to be added again :)
Is there a built in API that you can use? I know about the SPWeb.Navigation.QuickLaunch and the SPNavigationNode(Collection) structure etc. But is there another way?
Hope you can help :)
What kind of other way would you be looking for?
public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
SPWeb web = (SPWeb)properties.Feature.Parent;
// Check for an existing link to the list.
SPNavigationNode listNode = web.Navigation.GetNodeByUrl(list.DefaultViewUrl);
// No link, so create one.
if (listNode == null)
{
// Create the node.
listNode = new SPNavigationNode(list.Title, list.DefaultViewUrl);
// Add it to Quick Launch.
web.Navigation.AddToQuickLaunch(listNode, SPQuickLaunchHeading.Lists);
}
}
We have used the method above for a while and it tends to work out just fine.
If you can let me know what kind of thing you are trying to accomplish that manipulating SPWeb.Navigation wont let you do, I might be able to be of some more help
I have a site in SharePoint and I want to custom delete from a list. So, I'm creating the
public class ListItemEventReceiver : SPItemEventReceiver
{
public override void ItemDeleting(SPItemEventProperties properties)
{
if (properties.ListTitle.Equals("Projects List"))
{
Projects pr = new Projects();
string projectName = properties.ListItem["Project Name"].ToString();
pr.DeleteProject(projectName);
}
}
}
Where 'Projects' class has 'DeleteProject' method who deletes the item.
But it's doing nothing :(
I mention that everything it's ok in Feature.xml
Where am I wrong?
Edit (from 'answer'):
Yes, I've tried this:
properties.ErrorMessage = "projectName :" + projectName;
properties.Cancel = true;
in if clause and the event it's firing and displays the project name corectly.
I'm the farm administrator, and site administrator with full control over this site.
DeleteProject method it's right, because I've tried it in some other application (c#) and it's works fine.
A couple of things to check:
Is your list item reciever connected to the list, so that it fires?
Does the user that causes the trigger to fire have the the right to delete items?
Is there any programming error in DeleteProject?
Try putting in some logging to see how far it is running.
Edit
Could the problem be here:
string projectName = properties.ListItem["Project Name"].ToString();
Is the list item called "Project Name" with a space in the name?
Edit 2
From your comments, the combination of authentication and connection string means that it is the security context of the logged on user that is being used against the database. Check the rights of your user.
If event is firing and the only method pr.DeleteProject(projectName); is not working properly then it is difficult to guess what is wrong. If it is not confidential, please post your code and then I shall be in better position to identify what is wrong.
By the way, are you calling .Update() Method on list?
Please check out this link http://msdn.microsoft.com/en-us/library/ms431920.aspx
One more thing to care about is Itemed and Iteming events. It is better to use Before or After properties as appropriate in case of Item*ing events.

I have not worked with webparts for sharepoint before, but need to make change to a webpart, that needs to be propagated to some 700 websites. It is a change to one of the properties of the webpart, the value needs to be changed. Is there a way to get metadata for a webpart and change it directly in the database (I assume that is where it is stored.)?
Here is the scenario: Webpart contains a comma delimited list of document types (internal type) that it should display. Now there are new doc. types that need to be added to all 700 websites. I need a way to enumerate websites, get the webpart metadata, and add these new doc types to webpart. Currently they go manually to each website, click on edit, type in new doc type, and save it.
As others have said the correct approach is to programmatically achieve this rather than edit the content database which will make your installation unsupportable. I regularly use a console application to do this in a site collection made up of sites created from a site template.
Here is an example that changes the Title property of a ListViewWebPart. Updated to include code for recursive loop. I haven't tested this but it should work.
private static void ProcessSiteCollection(string url)
{
using (SPSite siteCollection = new SPSite(url))
{
SPWeb rootWeb = siteCollection.RootWeb;
ProcessWebs(rootWeb);
}
}
private static void ProcessWebs(SPWeb parentWeb)
{
foreach (SPWeb web in parentWeb.Webs)
{
try
{
UpdateWebPart(web); // Set web part properties
ProcessWebs(web); // Recursively loop through children
}
finally
{
web.Dispose();
}
}
}
private static void UpdateWebPart(SPWeb web)
{
using (SPLimitedWebPartManager webPartManager =
web.GetLimitedWebPartManager("default.aspx", PersonalizationScope.Shared))
{
try
{
foreach (WebPart webPart in webPartManager.WebParts)
{
if (webPart.Title == "My Web Part")
{
ListViewWebPart listViewWebPart = (ListViewWebPart)webPart;
listViewWebPart.Title = "Updated Web Part";
webPartManager.SaveChanges(listViewWebPart);
web.Update();
break;
}
}
}
finally
{
webPartManager.Web.Dispose();
}
}
}
Directly accessing the sharepoint content databases is a big "no no." That's the official answer. :)
That being said, I have only ever looked in the content databases and never tried to actually change anything manually.
My suggestion, would be to modify the existing web part to modify the property based on currently set property(s). (I am assuming that some currently set property is invalid or needs to be updated based on changes to the infrastructure.) ... If this is the case, you can validate the property; making sure that current property is changed to what it needs to be, and/or making sure future property changes are valid.
Good luck!
DON'T
Seriously, do not go into the content databases and edit it. That way you are not supported anymore if anything should happen and Microsoft will not support you anymore (not until you revert the database back to an earlier version from a backup that is).
You can use the API to access webparts in your sites, here's some code that should get you started:
Enumerate page webparts
I want to use the MultipleLookupField control in a web page that will run in the context of SharePoint. I was wondering if anyone would help me with an example, which shows step by step how to use the control two display two SPField Collections.
I'm not entirely sure I understand your question, especially the bit about displaying two SPField collections. Sorry if this turns out to be the answer to a completely different question!
Anyway here's a quick demo walkthrough of using the MultipleLookupField in a web part.
Create a team site. Add a few tasks to the task list. Also put a document in the Shared Documents library. Create a new column in the Shared Documents library; call it "Related", have it be a Lookup into the Title field of the Tasks list, and allow multiple values.
Now create a web part, do all the usual boilerplate and then add this:
Label l;
MultipleLookupField mlf;
protected override void CreateChildControls()
{
base.CreateChildControls();
SPList list = SPContext.Current.Web.Lists["Shared Documents"];
if (list != null && list.Items.Count > 0)
{
LiteralControl lit = new LiteralControl("Associate tasks to " +
list.Items[0].Name);
this.Controls.Add(lit);
mlf = new MultipleLookupField();
mlf.ControlMode = SPControlMode.Edit;
mlf.FieldName = "Related";
mlf.ItemId = list.Items[0].ID;
mlf.ListId = list.ID;
mlf.ID = "Related";
this.Controls.Add(mlf);
Button b = new Button();
b.Text = "Change";
b.Click += new EventHandler(bClick);
this.Controls.Add(b);
l = new Label();
this.Controls.Add(l);
}
}
void bClick(object sender, EventArgs e)
{
l.Text = "";
foreach (SPFieldLookupValue val in (SPFieldLookupValueCollection)mlf.Value)
{
l.Text += val.LookupValue.ToString() + " ";
}
SPListItem listitem = mlf.List.Items[0];
listitem["Related"] = mlf.Value;
listitem.Update();
mlf.Value = listitem["Related"];
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
EnsureChildControls();
}
Granted, this is borderline ridiculous -- everything is hard-coded, there is no error-handling at all, and it serves no useful purpose -- but it's only meant as a quick demo. Now build and deploy this web part and add an instance of it to your team site's homepage; it should allow you to get and set the tasks which are associated with the first document in the library.
The strange bit towards the end of the button Click handler, where we read a value from mlf.Value and then write it back again, appears to be required if you want the UI to stay in sync with the actual list values. Try omitting the last line of bClick to see what I mean. This has been driving me nuts for the last hour or so, and I'm hoping another commenter can come up with a better approach...
Hm. Works fine on mine, so let's see if we can work out how your setup is different...
It looks as though it's having trouble populating the control; my first guess would be that this is because the code makes so many assumptions about the lists it's talking to. Can you check that you've got a plain vanilla Team site, with (assume these names are case-sensitive):
A list called Tasks, with several items in it
A library called Shared Documents with at least one document
A column called Related in the Shared Documents library
The Related column is a Lookup field into the Title column of Tasks, and allows multiple values.
The first document in Shared Documents has a value for Related
Then add the webpart. Fingers crossed...
Hm. OK, I'm still trying to break mine... so I went to the layouts directory and created a file foo.aspx. Here it is:
<%# Page Language="C#" Inherits="System.Web.UI.Page" MasterPageFile="~/_layouts/simple.master" %>
<%# Register Tagprefix="foo" Namespace="Foople" Assembly="Foople, Version=1.0.0.0, Culture=neutral, PublicKeyToken=9f4da00116c38ec5"%>
<asp:Content ContentPlaceHolderId="PlaceHolderMain" runat="server">
<foo:WebPart1 id="fred" runat="server" />
<foo:WebPart1a id="barney" runat="server" />
</asp:Content>
WebPart1 is the webpart from before. WebPart1a is the exact same code, but in a class that inherits directly from WebControl rather than from WebPart.
It works fine, apart from a security validation problem on the postback that I can't be bothered to debug.
Changing the masterpage to ~masterurl/default.master, I uploaded foo.aspx to the Shared Documents library, and it works fine from there too -- both the WebControl and the WebPart behave properly, and the security problem is gone too.
So I'm at a loss. Although I did notice this page with an obscure might-be-bug which is also in SPFolder.get_ContentTypeOrder(): http://forums.msdn.microsoft.com/en-US/sharepointdevelopment/thread/63baf273-7f36-453e-8293-26417759e2e1/
Any chance you could post your code?
