Listview Showing Data From Related Entity And Changing It?
Jun 15, 2010
I am using entity framework. My model has entity tblGameInfo where in navigation properties are associations called tblPlayer1 and tblPlayer2 which links to entity tblPlayer. I have listview on my page where I want to show game info with players names. I have found that in of listview I should have e.g. one of those:
[Code]....
But it does not work. I got nothing displayed in a listview. I have tried many different options but cannot find working one. Probably is some simple mistake but I am new to asp.net and cannot find it. Second problem with this is editing. In edit template there is dropdownlist with all players.
[Code]....
How do I databind it? It is not allowed to bind and change properties? It writes me that element does not exist on a list of elements.

I have the following tables:
Campaigns (CampaignId, CampaignName, etc)
Urls(UrlId, CampaignId, UrlText)
I have a relationship setup between Campaigns table and Urls (FK_Url_Campaign) everything works fine when I try to add a new campaign but when I try to insert a new Url I get:
Entities in 'DatabaseEntity.Url' participate in the 'FK_Url_Campaign' relationship. 0 related 'Campaign' were found. 1 'Campaign' is expected.
This is my code:
// INSERT
public int Insert()
{
Url dbUrl = new Url();
dbUrl.CampaignId = (int)CampaignId;
dbUrl.Url1 = (string)Url;
context.AddToUrl(dbUrl);
context.SaveChanges();
return (int)dbUrl.UrlId;
}
Pretty much i want update/add new campaign and then I call Insert for Url. how would i go about doing this?

I am using Entity Framework for my .NET application. I have been able to return objects and their directly-related objects as well (very convenient), but I am having trouble getting the objects of those objects.
IEnumerable<Lot> i = (((ObjectSet<Car>)_carRepository.GetQuery()) .Include(a => a.CarTypes).Take(10).ToList()
This works and I can access carTypes, however I cannot figure out how to access tables associated with CarTypes (e.g. tables which have fields associated with the car types). I tried to use a Join however I was unable to figure out how to get it to work right.

I use VS 2010 Ultimate. I created an 'asp.net web application' from scratch, added a 'ADO.NET Entity Model' to my project (EF4).
The problem I'm having is that whenever I try and use an EntityDataSource to pull data out of my entity model I am near constantly getting the following error:
"The metadata specified in the connection string could not be loaded. Consider rebuilding the web project to build assemblies that may contain metadata. The following error(s) occurred:"

Using a very run-of-the-mill database, with identity int for primary keys, a Dynamic Data Entities Project (EntityFramework) displays the primary key for view and edit. When using Linq to Sql, the primary key fields are not displayed.
I would like to hide the primary keys and use Entity Framework (VS 2008, .Net 3.5 sp1).

I have certain columns in my DataSource such as "ID", "StartTime", "EndTime", etc.I would like to present them a bit differently in the listview.for example, I want to present the "StartTime" and the "EndTime" in ("hh:mm:ss") form, and would like to show only IDs smaller than 10.I thought about writing the code in
protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
{
}
I have no problem writing the conditions in code behind, but the question is:since the ListView1_ItemDataBound event handler is fired for every column, how can I know in which one I am concerned, and so which condition to use?for example, if it is a "StartTime" then I want to have (DateTime)item.ToString("hh:mm:ss"), but if it is "ID", I only want to check if ID<5.

There is a page in my project named Messages.aspx that shows the messages received [but obviously], using the ListView control.
I want that the user should be able to see the body of the message on the same page [Messages.aspx] just by clicking the subject of the message, which is ofcourse a link.[Messages.aspx?msg_id=some_id]. Hence the user would actually reload the same page to read the contents of the message.
Now what I want is that I should be able to write some code that would change the <LayoutTemplate> and the <ItemTemplate> of the listview during the runtime. [in the page_load event of course]
Previously the listview would look like this:
[Code]....
After the clicks any message to read it and the page gets loaded, I want the layout of the listview to look like this.

I have a user control, named productslist.ascx. On pruductslist.ascx, I am using Entity Datasource and a QUERY EXTENDER and LISTview. I have a page Defualt.aspx. On Defualt.aspx, I have a TEXTBOX with a SUBMIT button for searching the site. Everthing works fine so far, AS LONG as the results of the Search is posted back to Default.aspx. What I want is for the results of the search to be posted on a different page.
So I created a new page, Results.aspx and set the postback url to it.
What I want is that when a user clicks the Submit button, after entering a search string, the text the entered is used to execute the query on Productslist.ascx and the results displayed on RESULTS.ASPX. Again, everything works fine as long as the results are posted on same page hosting the usercontrol, BUT I want the postback url to be a different page. I am coding in VB and VS 2010.

I have a listview that shows the user the details of the members who have sent friendship request. The table from which the data come has two fields namely, sender_id[id of the one who sends friendship request] and receiver_id[id of the one to whom the request is sent].
There will be two columns in the listview. The first would show the pic and the name of the user. The problem is that how am I going to show the pic and the name if the table from where the data come does not contain these info. I know that the sender_id can be used to fetch the pic and name of the sender, but how should it be done?
Earlier I would do something like <%#Eval("fieldName")%>. But in the above described scenario the field is not present in the current table but the other one.

I have a Listview that is connected to an EntityDataSource. What I'm having trouble doing is showing fields of an association in the Item Template rather than just the id.
For example, what it currently shows:
Name: John Doe
Race: 3
What I wish it would show
Name: John Doe
Race: Caucasian
Some example code:
[Code]....
Obviously, I'm getting the number because Race_ID is an integer. What I'm less sure about is how to bind it or Eval it in some manner that will let me match that id to a name in the other table (which is associated). I've tried <%# Eval("Race.Name") %>' and a few other things to try to get a name rather than an ID but I always get either the id or nothing at all.

I have a listview that is showing its result by using a linq query. The linq query goes like this.
[Code]....
* db.Varer: Varer is a table that contains basic product information like proudct name, product nr. etc. ** a.fk_kategori_id == CatParamId : I'm just saying limit the result according to the Category ID (a.fk_kategori_id). The category id is coming from a dropdownlist (CatParamID) *** Join: Besides the Varer (Product) table I also have another table, Sizes. This Sizes table contains 6 columns (ID_Sizes (int) primary key and the columns: OneSize, S, M, L, XL, XXL all are bit (true or false)). There is a relationship between Varer table and Sizes table. It says that I can only insert a value into the "fk_sizes_id - column" of varer table if that value already exists as primary key within the Sizes table. **** I'm starting by picking basic product values like productId, ProductName etc from the Varer (a) table ***** Then I'm picking the corresponding Sizes values (onesize, s, m, ...) from the Sizes table. Now within my ListView I'm showing the above result by using Eval, like this.
[Code]....
And this works perfectly, but now comes the thing that is causing me trouble. I have the below drop down list (still within the ListView ItemTemplate):
[Code]....
I want this drop down list to be populated with only those of the "linq query's Sizes table result" that are true. By "Sizes table result" I mean these

I've written following code but I don't know by the help of which object I can access to markup property of listview :
protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
{
if(e.Item.ItemType == ListViewItemType.DataItem)
{
ListViewDataItem dataitem = (ListViewDataItem)e.Item;
int policyid = (int)DataBinder.Eval(dataitem.DataItem, "policyID");
if(policyid == 3)
//what should I write here to change the corresponding row's color?
}

getting data from multiple Entities models into an MVC controller. Most of the examples I have seen for using EF in an MVC2 app only use a single entitiy.
I have just started using MVC2 in C# using the Entity Framework models (CIOps.model) created from an SQL database. I can create the controller and views using single tables of the model in MVC2, but I just cannot get my head around how to get data from multiple entity tables into the controller (similar to joins in T-SQL). I have included an example below of the controller code that works with a single entity table, tbl_tours (tbl_tour in DB).
Could someone please illustrate how this code would be changed to include additional columns from FK tables in addition to tbl_tours columns. E.g. the clients name from the tbl_clients, the coordinators name from the tbl_employees, and costs from tbl_costs entities? Is it possible to do this directly using the EF model entities/classes that are already created and not use LINQ, POCO, Repositories, etc.? The FK relationships are already in the EF models. I have included the whole controller code, but I just need a few examples of how to join the multiple entities, not rewrite every CRUD function function in the controller. I think this will get me over the hump in using EF in an MVC2 App. Also ignore the fact I am using the home controller, this will change in the application.
