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'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

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 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 have written an event receiver that is activated on the 'ItemAdded' event of a 'Pages' list. The code runs fine, but my issue is this - during the call to my Sub ItemAdded, I want to change the value of a field belonging to the current list item (in this case an aspx page).
The idea is that I can configure the 'Title' field to be another value, which my event receiver configures, and by the time the user sees the page in edit mode, the new title will have been saved for the page. Here is my current attempt:
Public Overrides Sub ItemAdded(ByVal properties As Microsoft.SharePoint.SPItemEventProperties)
Dim newItem As SPListItem = properties.ListItem
Dim currentSiteTitle As String = properties.OpenWeb().Title
UpdateItemTitle(newItem, currentSiteTitle)
newItem.Update()
'newItem.SystemUpdate()
End Sub
As you can see, I've tried both Update() and SystemUpdate(), but in each case, when the user tried to check in the page, they get a message that the page has been modified externally. Plus, when viewing the page, the title field value has not changed.
Is what I'm trying to do at all possible, or is there a better way?
Cheers.

changing the properties.afterproperties will get around the save conflict. note that the afterproperties is a hashtable, but you can access it so:
properties.AfterProperties["Title"] = "My New Title";
ItemAdded Name says it all. It a Asynchronous Event that happens after the Items has been added, so is the issue with your calse. I suggest you to hook the ItemAdding event unless you have reason not to do so.
Refer the Link for Details on Asynchronous & Synchronous
The best way to accomplish this is use the ItemAdding event. This will allow you to change the Title value before it is saved to the database. Trying to change them in ItemAdded is possible but will cause the headaches you are experiencing.
Have you tried ItemAdding?
Now following on from the above, I found that when I was working with a discussion group the only place I could change any fields in the list item was in the ItemUpdating method, where I could assign the new value into the properties.AfterProperties hash corresponding to the item name as mentioned previously.
Unfortunately this didn't seem to automatically be run when a new reply was added to the discussion ( maybe it is in other list related scenarios ) but if I put code into the ItemAdded method ( ItemAdding was not being triggered either ) I found that it was being run but that I couldn't change the item from there, so I ended up with something like this in itemAdded:
public override void ItemAdded(SPItemEventProperties properties)
{
SPListItem item = properties.ListItem;
item.Update();
}
The outcome of this is that the field is updated but not before it is shown so that when the user is directed to the output page the list will look as it did before but if you change view or look at the details for the reply you will find that it has actually changed as it was supposed to.
This is good enough for me as I'm expecting most of my replies to arrive by email.
I've googled it, but came out empty. And the worst thing is that I know it is possible.
Anyway, I'm developing an application that uses the WebBrowser control to display information regarding an object (like Outlook does with the Rules and Alerts dialog box).
My question is how do I do for the click on a, say, hyperlink in the WebBrowser execute some function within the Windows Form?
For instance, say I have a link like this and when I click it I want the application to display an specific form, like the Outlook does when you click on hyperlinks like People and Distribution List
This looks useful: How to: Implement Two-Way Communication Between DHTML Code and Client Application Code
ChrisW's answer will work, but there's another way if you're just relying on hyperlinks.
In Comicster, I have links in my WebBrowser control like this:
New Collection
And then in the WebBrowser's Navigating event, I have some code to check if the user has tried to navigate to an "action:" link, and intercept it:
private void webBrowser1_Navigating(object sender,
WebBrowserNavigatingEventArgs e)
{
if (e.Url.Scheme == "action")
{
e.Cancel = true;
string actionName = e.Url.LocalPath;
// do stuff when actionName == "FileNew" etc
}
}
With a little bit of code you can even parse the URL parameters and "pass them through" to your host application's action, so I can do things like:
Edit this issue
... which will open a properties dialog for the issue with ID 1.
