Forms Data Controls :: Datalist And A Listview In A Master/Detail Relationship?

Jul 2, 2010

I am using a Datalist and a Listview in a Master/Detail relationship. Each time a DataList item is bound, a Listview is loaded dynamically. I have provided the relevant Layout and Item templates. It is worked fine for one item. But for more than one item, it will raise the following error: "An item placeholder must be specified on ListView 'ItemListView'. Specify an item placeholder by setting a control's ID property to "MyLayout$itemPlaceholder". The item placeholder control must also specify runat="server".
Despite having set up the item placeholder.

Here is the code-behind:

protected void NodeDataList_ItemDataBound(object sender, DataListItemEventArgs e)

{

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)[code].....


The Layout template:<asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder>

Forms Data Controls :: Listview Master Detail On Separate Pages?

Nov 14, 2010

I made my own master-detail pages using a listview. Rather than url, I use a listview event to set a session variable and response.redirect to the detail page, which on Page Load, loads the data from the database using the session variable, where it can then be edited. The details page is basically just text boxes and dropdownlists, but I used some third party controls and it all looks really sharp.

Here is the corner I pained myself into. Several dependent dropdowns on the master page filter the main listview. If I go back to the master page using response.redirect, the user would have to use the dropdowns again just to get back to where they were before they went to the details page. This is just not going to work.

To further complicate things, I wanted the master page to have paging on it. So if a back button reloads the page, they would have to set the dropdowns again, and page through the data again if needed. Egads.

The closest I have come to working is using a javascript back back button, but this fails after some postbacks on the details page (that are needed). And of course, the master page isn't refreshed when you go back to it (but I could probably live with that).

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

Jul 30, 2010

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.

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

Aug 6, 2010

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.

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

Jan 26, 2010

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 :: Insert Master And Children Records With One-to-many Relationship From Formview

Jun 4, 2010

I've been wracking my brains for a while. I have a master record that I want to add children to. In a database it's a one to many relationship with a foreign key in the child table.

I have a formview that I want to use to fill in all the master record info, and choose the child info from a dropdownlist, and click an add button, and have the add button add the child info to some control on a page. Then when the user clicks insert, the formview has an ItemInserting EventHandler that will handle all the logic for inserting the master, grabbing its primary Key.

So, I know what to do, I'm just not sure of what control to use, or what memory object etc., that I want to store the child info in until the master record gets created.

I'm sure this has been done a million times, but for all my searching, I couldn't find anything to help me. Does anybody have some advice or can anybody point me to an internet resource where this has been hashed out?

Forms Data Controls :: GridView And DetailsView Master To Detail

Apr 7, 2010

I am using a GridView and a DetailsView to establish a master to detail form, the idea is to let user select a record on Gridview and Detailsview will load selected record for editing. Here is declaration for the ODS and Detailsview.

[Code]....

this is working fine when I select a record from GridView and edit/update it in DetailsView. But it's not working so well when I insert a new record using DetailsView, because after insertion the selected record remains as the record selected in GridView.

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

Feb 6, 2011

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!

DataSource Controls :: Design Pattern For Pass (master/detail) Data Retrieval?

Apr 18, 2010

design pattern that works well with Visual Studio data tools against an MS SQL server; to retrieve a subset of an object's fields for all rows, and then on-demand retrieve the remainder for one row. I.E. just the small summary fields that I will serialize to a master grid view, then the larger properties including a large blob that I will render in a detail view. The performance hit from retrieving the large blob with the master result list would be too great.

The data shape is static, and I can define two separate data classes to match the specific summary vs. detail information returned. However that sounds anti-pattern-ish, to define the data classes specifically to suit the presentation layer. It also presents another problem, how to translate from the summary item to the detail item in an object-oriented way?

Forms Data Controls :: Accessing Master Formview Data From A Nested Detail Formview?

I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.

Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?

I am extremely new to ASP and just started learning. I want to know which is better between Datalist, Gridview or Listview if I need paging and sorting functionality? This is what I have so far.

I've tried Datalist but I am having trouble with the paging portion. I've tried gridview and listview and got the paging to work but for some reason, when I click on Pg 2, it refreshes the search or something and what was shown on Pg 1 would appear again on Pg 2.
