Delete not working on List.aspx - out of box

Posted By:      Posted Date: August 24, 2010    Points: 0   Category :ASP.Net


I'am trying to use Dynamic data web site on my project. I have Visual Studio 2010 enf Framework 4.0. I create the default project with the wizard. I add my own Entity Data Model.

When I try to use the "delete" autogenerated button on List.aspx, on the table ServerSetting (see image below), I receive a null exception.  I have no custom code involved in this operation and cannot seem to determine what is Null.

Any help would be appreciated!



[NullReferenceException: Object reference not set to an instance of an object.]
   System.Data.Objects.Internal.ForeignKeyFactory.CreateConceptualNullKey(EntityKey originalKey) +30
   System.Data.Objects.DataClasses.EntityReference.NullAllForeignKeys() +722
   System.Data.Objects.EntityEntry.NullAllForeignKeys() +235
   System.Data.Objects.EntityEntry.Delete(Boolean doFixup) +77
   System.Data.Objects.EntityEntry.Delete() +9

Viewselector is not working in a custom ASPX list view nor does the custom view display in the list


I created a custom ASPX page to display data from a linked datasource in SharePoint designer. (Let's call it NewView)   After creating the new page I inserted a web part zone then inserted a data view into the zone and attached the default master to the page.   From the linked data source, I added the columns I wanted to display in the data view and added additional columns from the 2nd linked list as a subview.

I copied the following code just after the </WebPartPages:SPProxyWebPartManager> tag and just before the <WebPartPages:WebPartZone tag:

  <table class="ms-menutoolbar" cellpadding="2" cellspacing="0" border="0" width="100%">
    <td class="ms-toolbar" nowrap="">
     <SharePoint:NewMenu runat="server"></SharePoint:NewMenu>
    <td class="ms-toolbar">|</td>

How to use a drop down list to edit in the standard Edit.aspx with DD?


Hey All,

I'm brand new to Dynamic Data and to ASP.NET.  I've been able to fumble around and get the calendar extender up and running and a few other customization options implemented, but I can't seem to get this drop down list to work - even after reading tons of online info.  The good news is that my web page/application is VERY simple, so hopefully you guys can help me out.  I'm working in VB btw.

I have a list of road projects submitted to me by local governments.  One of the fields is SponsoringAgency, which has a limited number of possible entries (the names of member governments).  Thus, when they submit a new project, or edit an existing one, I want to limit the input into the field "SponsoringAgency." I'm trying to use a dropdownlist because I'm familiar with it from Access, but it may not be the best approach.  Imagine you just setup a brand new, standard DD website, how would you get this to work?

Methods tried and failed (probably because I don't understand them fully):

UIHint - The closest I can get with this is an error saying that since SponsoringAgency isn't a Foreign Key, I'm out of luck.

Creating a SponsoringAgency Table - In my data layer, I created a second table with a list of government names.  I then tried se

Delete list items en masse?

Is there a way to delete list items en masse from a SP list?  I am on MOSS 2007.  In order to use a particular site as a site template I had to save with content and I don't want the content.

SharePoint Designer: insert custom list not working anymore



Suddenly sharepoint designer decided today that it doesn't want to insert a custom list form anymore...
To be more specific, it doesn't work anymore in a site that uses the Microsoft budgeting and tracking template. In a website that uses an out of the box template, it still works.

It did work before, because I did it in other websites using the same template (it's broken there as well now).

Why oh why does SharePoint refuse to do this now?
I searched google and here on the forums, but all I could find was some issues after installing SP1, but we did that already long time ago and it was still working after that. I checked with our infrastructure guys and they didn't install new updates they say.

I also tried the solutions listed here: http://blogs.msdn.com/spdsupport/archive/2008/07/03/how-to-fix-custom-list-forms-will-not-insert-or-show-up-on-the-design-surface-of-sharepoint-designer.aspx
But they don't fix the problem.

So my problem is, I can go to Insert > SharePoint Controls > Custom List Form
I pick my list, content type and form type, I hit OK and... nothing happens.

the list.aspx bad behaviour


I have two tables : table1 (primary) and table2 with one to many relation .

table 1 has more than 130 000 records , table2 has near to 200 000 records .


when i am trying to list table2 , the table2/list.aspx will build filter depending on the relation.; this operation slows down the page (drop down list with 130 000 record)

 I disabled the filter by using the attribute AutoGenerateFilter = False .


now the problem is that table2/list.aspx?key=value will list all the recoreds in table 2 .


why is the page not using the query that is related to the parmeter passed to it ?


List.aspx (or list.aspx?key=value) will always get all the recorders from the table2  after disabling the key relation filter .

I want my table2/list.aspx?key=value  to query the table2 depending on the passed key which is the expected behaviour .

please advice .

Ajax dropdown list not working

Dear All:I just implemented a simple Ajax drop down list. The problem I'm facing is that when I run the project I will not be able to select the values from drop down even though there are 4 values coming in. Here is my code:Default.aspx<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Untitled Page</title> <link href="StyleSheet.css" rel="stylesheet" type="text/css" /> </head> <body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server" /> <div > Name:<asp:DropDownList ID="colorValue" runat="server" OnSelectedIndexChanged="colorValue_SelectedIndexChanged" ></asp:DropDownList> <ajaxToolkit:DropDownExtender ID="DropDownExtender1" runat="server" TargetControlID="colorValue" DropDownControlID="DropPanel" > </ajaxToolkit:DropD

Delete not working all the time.

From time to time i am getting this error when attempting to delete a file. Exception Details: System.IO.IOException: The process cannot access the file 'D:\gallery\images\Untitled-1.jpg' because it is being used by another process.

Anyone got the SharePoint List Adapter working with SQL 2005?

Like the authors of some other similar posts, I cannot see the SharePoint list dataflow source and destination options after installing SharePointListAdaptersSetupForSqlServer2005.msi from codeplex.  The options do not appear in the SSIS Data Flow items tab within the "Choose Toolbox Items".  Anyone manage to figure this out? If i install it on my dev laptop - I get these options and can add them to my toolbox - however I have both SQL Server 2005 and 2008 on this machine.   On my 64 bit server however I only have SQL 2005 and nothing! I would love to use this as the last time i wrote a web service extraction is was a very unpleasant few days of my life. Ritchie

Remove items from a list literally not working as needed

This is why SharePoint drives me insane.  Everything I have been able to find on the web says I *can* programmatically remove list items from a list, all I have to do is a declining loop.  I have even copied verbatium several code examples found in this forum and on the web and every last one of them gives me a "Collection was modified; enumeration operation may not execute." error in the Event log.  This is a C# Windows Form Application we want to use to remove a common announcement from any announcement list in our entire site (top down).  We can *add* it to every announcement list without issue (seperate code).  Can anyone point out to us the error in our code below? using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using Microsoft.SharePoint; using System.Text; using System.Reflection; using System.IO; using System.Diagnostics; using System.Xml; namespace RemoveAnnouncement { public partial class RAForm : Form { public RAForm() { InitializeComponent(); } private void removeAnnouncment_Click(object sender, EventArgs e) { const string a = "Application"; try { if (tlsURL.Text.ToString() == "http://" || tlsURL.Text.ToString() == &qu

Cannot delete rows in a list via Lists web service's UpdateListItems-function, even though I am abl

Hi all, I'm trying to delete some rows in a SharePoint 2010 Foundation list via Lists.asmx -web service's UpdateListItems. The web service is called from BizTalk. I am able to create rows, but for some reason delete fails. I also use "GetListItems"-function without problems. The exception I get is Microsoft.SharePoint.SoapServer.SoapServerException. The message is "Cannot access a closed Stream." The updates-element of the UpdateListItems-function is as follows (well, a part of it, the real one has more Method-elements, but you get the gist..): <Batch OnError="Continue" ListVersion="1"> <Method ID="1" Cmd="Delete"> <Field name="ID">1900</Field> <Field name="IMEI">GFA-687</Field> </Method> <Method ID="2" Cmd="Delete"> <Field name="ID">1901</Field> <Field name="IMEI">OVG-567</Field> </Method> <Method ID="3" Cmd="Delete"> <Field name="ID">1902</Field> <Field name="IMEI">OXI-570</Field> </Method> </Batch> I've also tried that Batch without the IMEI-information, as well as with a valid ViewName.

Hello Everyone, I have a customer who is having problems with an SP 2003 site. Here is what the concern is: I have a list on an SP 2003 site... and I am attempting to delete a row from the list... To do that I am setting the list in "Datasheet view". I select the row, right click and select the "delete" option from the menu and delete the row. Then when I click on the "Show in Standard View" button, I get the following error: "An unexpected error has occured. Changes to your data cannot be saved. For this error, you can retry or discard your changes". When I retry, it says the same error msg... Then I have to discard my changes, and I am not successful in deleting the row.
