Forms Data Controls :: Update Detail View In Vb.net?
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.

MVC :: 3 Master / Detail View Inserts New Detail Records Instead Of Updating Existing
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!

Asp ModalPopupExtender Not Displaying Detail View?
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"

Display List Of Values In MVC Detail View?
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);
}

Forms Data Controls :: Moving From One Field To Another In A 'Detail View' Form?
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"?

Forms Data Controls :: Master / Detail With Additional Detail Paging
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.

[Code]....

DataSource Controls :: Master Detail Using EF Model Where Condition For Detail - 3.5 Sp1?
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.

Forms Data Controls :: Use Manual Insert & Update With FormView (master/detail)
I havea master/detail page usinggridView andformView attached to a pair of entityDataSources. The automagic insert and updates quit working after making heavy customizations to the form (replacing ID numbers with persons' name, etc). The automatic CRUD throws errors on insert and silently fails on edits, but delete works fine (woot!!!).

After two fruitless months of trying to get the automatic insert and update to work, I wrote my own code to replace them. This has caused a new problem: The records are inserting correctly (haven't made it to the updates yet) but the automatic is still firing and throwing an error. I've tried turning the automatic inserts and updates off - the insert still fires, but an exception is thrown that the form doesn't support inserting records.

I can post code but I don't know whats relevant. The two files are in the neighborhood of 220 lines each.

Basic structure is

gridView

formview tied to gridview

formview fires OnDataBound (code replaces numbers with human readable stuff) formview fires OnItemInserting (fires custom code to assemble new record and save to the database outside the entityDataSource) formview fires OnItemUpdating (when completed, will update records similar to OnItemInserting) entityDatasource for gridview

autogenerate where clause turned on Enable Insert, Delete & Update turned on entityDatSource for formview

Forms Data Controls :: Master / Detail Page - Updating Detail Records - Need Access To Master ID (key)
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 ListViewis 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)columnbound 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.

C# - MVC Routing For Master / Detail Views With "Detail Children"
I have the basic Master / Detail Views working great with the default ASP.NET MVC Route; however I would like to build some URLs like this: /Class/Details/5 -- General Detail view [Working] What I'm not sure about (and I'm not tied to this URL format, just something roughly equalivent.)

/Class/5/Details/Logs -- Detail View with Logs
/Class/5/Details/Status -- Detail View with current Status

Another way to put this, is like this: /{controller}/{id}/{controllerSpecificMaster}/{action}/ What I'm trying to avoid, is cluttering up my ViewsClass directory with a bunch of Views, which are all basically derivatives of the Details view. I'm on ASP.NET MVC 1 and .NET 3.5 SP1.

MVC :: How To Return / Update A Partial View Inside Another View
First of all, it's ridiculous how you have to sign in to your live account before logging into yet another account in order to simply log in to the forums. Anyway, that's irrelevant to the real issue at hand.

I have a view that has input fields for searching for customer orders. A have a button to execute this search which invokes an actionresult method in the controller for this view.

What i want is the results to be displayed below these input fields on the same page. My idea of solving this (with little practical experience of asp.net mvc) was to have the actionresult method return a partial view and also have the "main" view take use of this partial view by the html.renderpartial method. well, the result is i get a partial view only rendered and the main view with the input fields etc disappears.

I get that my way of thinking may have not been very logical, but really how do you solve this very simple task of updating a partial view only of a main page?

[Code]....

MVC :: Update A Dropdown List In 2 RC 2 View
I was trying to implement a dynamic update of a dropdown list in an ASP.NET.MVC2 RC 2 view. My code didn't work. So, in order to verify my approach, I resorted to a published code, which supposedly should be correct: In the View:

<%= Html.DropDownList("Numbers",(IEnumerable<SelectListItem>)ViewData["Services"]) %>
<select id="Select1">
</select>
<input type="button" id="Button1" value="Fill By Array" />
<script language="javascript" type="text/javascript">
$(function() {
$("#Button1").click(function(e) {
e.preventDefault();
var data = [];
$.getJSON("/Home/GetListViaJson", null, function(data) {
data = $.map(data, function(item, a) {
return "<option value=" + item.Value + ">" + item.Text + "</option>";
});
$("#Select1").html(data.join(""));
});
});
});
</script>
In the Controller:
[HandleError]
public class HomeController : Controller
{
public ActionResult Index()
{
//ViewData["Message"] = "Welcome to ASP.NET MVC!";
ViewData["Numbers"] = GenerateNumbers();
return View("Index");
}
[AcceptVerbs(HttpVerbs.Get)]
public JsonResult GetListViaJson()
{
return Json(GenerateNumbers());
}
private static List<SelectListItem> GenerateNumbers()
{
var numbers = (from p in Enumerable.Range(0, 20)
select new SelectListItem
{
Text = p.ToString(),
Value = p.ToString()
});
return numbers.ToList();
}
public ActionResult About()
{
return View();
}
}

The Html.DropDownList was correctly populated on PageLoad() event. But the GetListViaJson() action method, when called on the button event, did not update the "Select1" element. how to solve this update problem.

MVC :: How To Update A Collection Of Objects In A View Model
I have been trying to design a form, which uses a view model that contains an object array. I want to set up this form so that when the submit button is clicked, all the members of the array are updated. Here is my code:

The class definition of the array element:

[Code]....

The problem is that when I clicked the submit button, none of the luSubject objects in the array Subjects got updated. But if I set up some initial values for the members of the luSubject objects, for instance, set the Name field to be "Maths" in the constructor of luSubject class, then it got displayed on the text box when the form page was loaded. This suggests that this form could display the data in the array, but cannot update it.
