I have 2 Details Views. Each Details View has its own Update function.How can I call/execute the 2nd Details View update event when I click on Update Button of 1st Details View?
Protected Sub DetailsView_1_ItemUpdated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewUpdatedEventA rgs) Handles DetailsView_1.ItemUpdated
'To call DetailsView_2_ItemUpdated event here ...
End Sub
Protected Sub DetailsView_2_ItemUpdated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewUpdatedEventA rgs) Handles DetailsView_2.ItemUpdated
'To call DetailsView_1_ItemUpdated event here ...
End Sub

article on binding to a list and I've got that working fine on one view. But what I'm stuck when doing it off a master record. Everything seems to work except that when I look in the database the detail records previous associated with the current master have their Foriegn key to master set to Null and a new set of detail records have been inserted. I've got a really simple form for this object
[Code]....
The form collection comes back with the expected prefixes:
[Code]....
And the Controller.UpdateModel(master) binds all the properties correctly. But when I call dbContext.SaveChanges it issues the follow sql from sql profiler (psuedo code)
[Code]....
I've got a work around that works but it's pretty hackish and I'm currently not matching up the keys so it's dependent on everything coming back in the right order. Plus I've got to include all the fields that I want updated.
[Code]....
I thought that entity framework's code first was the culprite but I've unit test that and it works fine. I've got a feeling that UpdateModel is somehow removing and re-adding the children. Has anyone else got this to work? Of course, I could throw in the towel and parse the indexed field names myself, but I'm so close!

Im making a Master details web page ASP.NET. I have one aspx page with all the items in a listview, then a link to another page to show the details view, but I dont want to use a asp:detailsview control becasue it generates a table, and I want a more complex layout. I want work each property of the item, but I dont know how. I want to do in LINQ. This is my very bad aprox: I need an orientation of how to get ONLY one item from the LinqDataSource on the page load and not to query the database everytime I need a column. I dont need biding because I only need to show data, not insert, not update, not delete...

Members view (index) that lists members that users can select to show a partial view in the same view with details for the selected memberUses jquery (Ajax.ActionLink) to call a partial view method in the members controller to then load the members detail sectionWorks fine up to here....but I'd like to load the partial view with "member" details for a default or random member on initial load -- ie not through the Actionlink selectionHow do I invoke the partial view method on the initial load?

My problem is this I have a base page that creates content dynamically. There are buttons on my Master Page that fire events that my base page needs to know about. But the OnLoad function on my base page fires before my Button_Command function on my master page. So I either need to figure out a way to load my base page after the Button_Command function has had the chance to set a variable or I must call a function in my base page from the Button_Command function.

I have an "Edit" page that uses a FormView bound to an EntityDataSource. The page is called with the ID field of the record to edit in the query string: "EditEmployee.aspx?ID=10". The EDS the FormView is bound to is using: AutoGenerateWhereClause=true and a QueryStringParameter. Below the FormView I have a ListView that contains some child records of the FormView. The ListView is bound to a seperate EDS and also uses the (same) QueryStringParameter.
The problem I am having is when this ListView attempts to Insert or Edt a column I receive an error because I don't have the ID field (EmployeeID) of the parent bound anywhere in the ListView (and obviously, it is setup as a ForeignKey so it fails, like it should). Any advice on the best way to get this ID (EmployeeID) column bound in the ListView? There are many things I can do in code behind, but I would like to solve this in the markup if possible. I can move the ListView so that it is inside of the FormView if necessary.

I have a LinkButton within a User Control and it has handled with:
Private Sub LoginLinkLinkButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LoginLinkLinkButton.Click
Response.Redirect("/", True)
End Sub
On certain ASPX pages I would like to handle the click from the page's code behind, opposed to within the user control. How do I override the handle within the control from the parent's code behind page?
Update:
Based on the answer, I have the following no added to the User Control:
[code]....
The problem is determining the correct syntax for the if line because the above is invalid.

am using a ModalPopupExtender within an updatePanel to show a detailView when a user selects a "Details" Button within a GridView.The problem is that when the button is selected the popup is not being displayed. I have stepped through the code and the mdlPopup.Show() method is being executed but the popup does not "Show" Could someone perhaps help me out with what is happening?Here is my Code:
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetRequests"
TypeName="RequestDAL" SortParameterName="SortExpression"></asp:ObjectDataSource>
<asp:ObjectDataSource ID="ObjectDataSourceDetails" runat="server" SelectMethod="GetRequestsDetail"

[Code]....
I've get a nullreferenceexception where the car entitity does not have a reference towards manufacturer. I'd like to output a " " if no manufacturer exists.

I am new to web apps, MVC, and LinqToSql. I created an MVC web app using the NerdDinner tutorial as a guide. I'm now adding many-to-many relationships to it. And am just running into walls at every step. I have a multiselect list in the Edit and Create views. For the Detail and List views I would like to list the selected values.
I have 3 tables: Company, Subcontract, and a link table CompanyToSubcontract. I have code which gets the guid of my selected companies from the CompanyToSubcontract table which is used elsewhere in my code. I do not know how to display it.
Should I write another function to get the Company names from the Company table? Do I pass the list of names to the SubcontractDetail view and then somehow loop through it there?
Same questions with the SubcontractIndex view. The Index view is in table format, I'd like to have a "Company" column which has a comma separated list of the companies for each subcontract row.
[Authorize]
public ActionResult Details(string id)
{
subcontract subcontract = subcontractRepository.GetSubcontract(id);
IEnumerable<Guid> cmpny = subcontractRepository.GetSubcontractCompanies(subcontract.subcontract_id);
if (subcontract == null)
return View("NotFound");
else
{
return View("Details", subcontract);
}
}
[Authorize]
public ActionResult Index()
{
var subcontracts = subcontractRepository.FindAllSubcontracts().ToList();
return View("Index", subcontracts);
}

have been through this que a long time ago, but seem no ans was found. I gonna post it again.I have a Detail view to control the detail of user, but i didn't bind it with any data source, the only i use is bind it with the sql command in vb.net code. I can open the Dv in edit mode but cannot update it with update button. I have read many post but some use data source or use store procedure. I can't use both.I do this because i wan to update multiple sql statement.

I'm currently working on a project, i have got a web form and some text fields and drop down lists and radio buttons, i manage to store them in the database after the users click on the submit button. Now i need to display all these values in a detail view in a new web form page. Is it possible? How should i go about doing it or is there any other alternatives since i did not use the grid view for users to store their information.

I am using a "Detail View" to edit the data in my "Customer" table. The fields are "CompanyName", "ContactPerson", "StreetAddress", and "City". If I type data into the first field ("CompanyName") and then press the "tab" key, control moves to the second field "ContactPerson". However, if I type data into the first field ("CompanyName") and then press the "Enter" key, instead of control moving to the second field ("ContactPerson") the program closes the form.
Is there someway that I can control the action of the "Enter" key so that this will not happen?
Also, is there any way that I can have control move from the first field ("CompanyName") to a field other than the seconc field ("ContactPerson") if the content of the "CompanyName" field contains the value "Internal"?

1) I know there are lots of web sites that describe in what order events are called during the Asp.Net page life-cycle. But is there also a tool, perhaps Reflector, that would enable me to figure out by myself in what order are ALL the page's events and their event handlers called during the page's life cycle? 2) Would you say that trying to figure out exactly what is going on under the hood is a good idea or a waste of time? To clarify - I'd like to figure out exactly what is going on when a control tree is build - thus all the method calls, all the events called etc needed for control tree to be build ( I imagine there are hundreds or perhaps thousands lines of code written just for building a control tree).

I'm trying to setup is a News module with article listing paging and article detail paging. I have a GridView with paging that lists my articles just fine. In that list, some article titles have links that direct to an article detail page by passing in the articleID to the details page. I was able to setup my details page, which uses a DetailsView control, to use paging by using an ObjectDataSource with pageIndex and pageSize parameters from the querystring. Once on my detail page, I can use my navigation arrows to move through Next and Previous articles just fine.
No matter which article I click in my article list, my detail page always starts with pageIndex 0 and thus not the article I clicked on. I understand why that is because it's going by pageIndex value instead of articleID. What I need it to do is, set the detail to whatever articleID i pass in, then allow me to navigate Next and Previous to THAT particular article instead of starting me off from pageIndex 0.

When I send a strongly typed ViewModel containing other ViewModels nested inside (basically spanning 3 tables into one object) all the data is correctly presented when debugging. However it complains at rendering time with an exception "Compiler Error Message: CS1061: 'object' does not contain a definition for 'Name' and no extension method 'Name' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)"
and the error is thrown from mvc2-rtm-sourcessrcSystemWebMvcMvcViewPageControlBuilder.cs method:

I've been experimenting with using EF (asp.net 3.5 sp1) with a master detail page. Using northwind as the database, I'm simply trying to have categories as master and products as detail. I have read everything I could find on the net about the where condition and it still fails with this error as soon as I click the select link in the master grid:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: A property with name 'CategoryID' does not exist in metadata for entity type 'WebAppEF01.Products'.
What strikes me is that the CategoryID column is not exposed by the EF model. That's been rolled up into the navigation element 'Categories' I suppose...but on the surface this seems to create the problem I've running in to. I've tried turning off the autogeneratewhere clause but didn't have success. The code for this page follows below.
