Here a Picture of my EDM:
I need find out all objects CmsAdvSlot connected with a CmsMasterPage (it is working in my code posted belove), and DELETE the result (CmsAdvSlot) from the DataBase. My Problem is I am not able to DELETE this Objects when I found theme.
Error: The object cannot be deleted because it was not found in the ObjectStateManager.
int findMasterPageId = Convert.ToInt32(uxMasterPagesListSelector.SelectedValue);
CmsMasterPage myMasterPage = context.CmsMasterPages.FirstOrDefault(x => x.MasterPageId == findMasterPageId);
var resultAdvSlots = myMasterPage.CmsAdvSlots;
// It is working until here
foreach (var toDeleteAdv in resultAdvSlots)
{
context.DeleteObject(myMasterPage.CmsAdvSlots.Any()); // ERORR HERE!!
context.SaveChanges();
}

I have a property object that has many activities associated to it. I want to delete all the activities and then add specific ones back in. I am doing this all before the objectcontext save. I am using multiple objectcontexts and attaching/detaching the objects. I am getting the property from the propertyreository objectcontext which is the primary context. Then I get the user which takes a bool to determine if I want to detach from the userrepository object context. I attach to the propertyrepository.
All is good but when I remove all the activities from the property object (entityobject) and then try to attach the activity that I retrieve from the database I get the error: key already exists in the ObjectStateManager Error. When I remove all the activity entity objects from the property entity object they are not really deleted from the objectcontext or the database until I use the save() on the objectcontext which will change all the entity object statuses. How then after I remove the activity do i add it back to the property.Activities?

I am using VS 2008 SP1. My also have included CSS Friendly adapter [URL] in my project ( I mentioned this because my GridView Empty data template is not showing when using GridView's CCS Friendly adapter). I have a GridView and a DetailsView. When a record in GridView is selected its details information is shown in the Details View. Type of Data source I am using is ObjectDataSource. My Insert and Update methods works perfectly. It is only the Delete method that is passing null values to the underlying object delete method. My source codes for both the UI, BLL, DAL is shown below

I am using the ajax reorderlist control from the latest Ajax Control toolkit. Based on the logged on user, I need to hide the "edit" and "delete" links. They should be visible to admin, and not visible to others. I used to control this when I was using a gridview just by calling the column and setting it's visible property to false. I have tried using:
ReorderListMinutes.TemplateControl.FindControl("lnkDeleteAgendaItem").Visible =
False
ReorderListMinutes.TemplateControl.FindControl("lnkEdit").Visible =
False
This returns an error of the dreaded "Object reference not set to an instance of an object."

Working through the tutorial http://www.asp.net/mvc/tutorials/iteration-1-create-the-application-vbI am unable to delete anything as that method is not passing an object to the Delete POST function.Or more specifically, the object is nothing.Stepping through the GET method I get a bizzare 'There is no code after this point' after Return View(objectToDelete)The LINQ query for the GET method is the same as that for the Edit method but that is working fine.

I keep getting Object Reference not set to an instance of an object errors when I try to use the ListView delete function. It is a fairly freshly created listview and is very close to the original template so not sure what is going wrong. Some possibly relevant code:
[Code]....
I also put in a breakpoint in the deleting event (only reason I added the deleting event) to look at the status of everything. When I do: Contact delContact = (Contact)e.Entity; and look at the values, the values for almost everything are set to null. It does have the correct value for the ID of the contact object that needs to be deleted. When I continue to step, it jumps to my designer.cs file and appears to break here:
[Code]....
likely because _Case_ID is null. The exact exception I'm encountering is: System.NullReferenceException: Object reference not set to an instance of an object. While I could probably re populate the object with correct values, that doesn't seem likely to address the real cause of the problem.

I'm having a gridview in my aspx page with checkbox, User can select one or more than one record(s) at a time and clicks on delete button, Then i'm constructing an object of my DTO and adding all the checked row's Primary Key (DataKeyNames - GUID's in my case) to a serializable class and generating an XML and sending it as parameter to the Stored Procedure.
My Doubt is, can i bulk delete all the rows from database table those are present in my XML document??
If it works, I can do bulk update with XML only, i already did bulk insertion by generating an XML..
My Another Question is, Will it affect the performance? Each time when i construct an DTO object and adding it to the Generic List?
Which one is better, I mean ObjectDataSource or SQLDataSource or my XML method?

How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";
}
But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.
Specified argument was out of the range of valid values. Parameter name: index
How do I reference the delete button so the edit button is not affected in this case?

Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically). However, how can I delete the actual image that resides in my image folder (i.e. from "pix" folder )? What is the best way to delete image? If using code behind, how? Please write a full code for me. Here is my source code.

I am interested in building an intranet document management system to be used from Internet Explorer using ASP.net, VB.net, and MS SQL Server but have no experience in doing a project like this. Supported file types would be txt, pdf (from scanner or imported from file system), or jpg. What concepts I should look at researching/learning about to build the system in a way that files will be stored as small as possible, retrieved and displayed quickly, and secured. The users would be spread out over a regional area covering 4 states.

I have a grid contol that allows delete what I would like to have is someway to say Are you sure you want to delete?I found this code online, and tried it but it did not work, Do I need something more some behind code maybe?Here is what I found online:Adding 'Delete Protection' to controls If you use a control set up to allow Delete, the Delete button gives a straight delete without any warning, which can be dangerous.To give a warning dialog box, add an OnClientClick event to the Delete button, as follows.
<asp:LinkButton
ID="DeleteButton"
runat="server" CausesValidation="False"
CommandName="Delete"
OnClientClick="return confirm('Are you sure you want to delete this record?');"
Text="Delete">
</asp:LinkButton>
Here is my code: You can see where I added the code from above.
<ItemTemplate>
ID:<asp:label id="IDLabel" runat="server" Text='<%# Eval("ID") %>' /><br />
Name:<asp:label id="NameLabel" runat="server" Text='<%# Bind("Name") %>' /><br />
Destination:<asp:label id="DestinationLabel" runat="server" Text='<%# Bind("Destination") %>' /><br />
OutDate:<asp:label id="OutDateLabel" runat="server" Text='<%# Bind("OutDate") %>' /><br />
ReturnDate:<asp:label id="ReturnDateLabel" runat="server" Text='<%# Bind("ReturnDate") %>' /><br />
LeaveTime:<asp:label id="LeaveTimeLabel" runat="server" Text='<%# Bind("LeaveTime") %>' /><br />
ReturnTime:<asp:label id="ReturnTimeLabel" runat="server" Text='<%# Bind("ReturnTime") %>' /><br />
ContactNumber:<asp:label id="ContactNumberLabel" runat="server" Text='<%# Bind("ContactNumber") %>' />
<asp:linkbutton id="EditButton" runat="server" CausesValidation="False" CommandName="Edit" Text="Edit" />
<asp:linkbutton id="DeleteButton" runat="server" CausesValidation="False" CommandName="Delete" OnClientClick="return confirm('Are you sure you want to delete this record?');" Text="Delete" />
<asp:linkbutton id="NewButton" runat="server" CausesValidation="False" CommandName="New" Text="New" />

I am using Sharepoint Designer and trying to insert a Delete button into a gridview. I added this to the top of my ASPX:
<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"
Assembly="Microsoft.SharePoint, Version=11.0.0.0, Culture=neutral,
PublicKeyToken=71e9bce111e9429c" %>
and I added this as a Gridview column:
<SharePoint:DeleteItemButton
runat="server"
ID="CustomFormDeleteItemButton"
ControlMode="Edit"
/>
and this is the error I get:
An error occurred during the processing of . System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'. 'SharePoint:DeleteItemButton' is of type 'Microsoft.SharePoint.WebControls.DeleteItemButton'.
