I would like to display students and their grades with a GridView and LinqToSQL like this:
[Code]....
I found this topic but it doesn't answer my question: http://forums.asp.net/t/1557987.aspx
I have a many-to-many relationship between students and assignments called "grades".The grade for the assignment is stored in that table in a "gradeNumber" column.The many-to-many relationship seems to be a problem.I tried adding a TemplateField to my grid:
[Code]....
It doesn't work: ...student does not contain a property with the name grade.
It does work when I use class.name however to get a student's class he is in.In code students .grade[0].something works however My LINQ entities are extended with custom code to allow me to retrieve studentx.Assignments or assignmentx.Students.(I would also like to specify which assignments should be displayed in the grid.)
I am building a user registration form in asp.net. I want to check if the username is available or not on the leave event of the TextBox. I am not able to get the Leave Event of the TextBox.
I have a gridview displaying "registrationtype id" (FK) from the registration table. I want it to display the related name instead of the id from the registartiontype table.
I am using this to display a value from database to text box. I am not using the dataset just for this text box but for other dropdown lists too (which are working alright), so the fact that I am using dataset for a textbox is not going to be very expensive in terms of performance.
Basically, I am doing something like this -
public partial class _Default : System.Web.UI.Page
{ private string varState; protected void get_city(object sender, EventArgs e) {... //code specific to this function which is working alright varState = (ds.Tables(0).Rows(0).ItemArray(0)).ToString(); textbox1.text=varState; } }
On Build I am getting -
error CS0118: 'System.Data.DataSet.Tables' is a 'property' but is used like a 'method'
Title is a lookup table of titles (Mr, Miss,...) and its got a relationship with table User by TitleId.
Now I'm trying to display the data in a web page using .net and Entity Framework. I'm using a ListView control and a query as a source. it all displays fine except for the Title.
Here is my code:
MyEntities _entities = new MyEntities (); User user = new User(_entities); IQueryable u = (from x in _entities.Users where x.Active == true select x); ListView1.DataSource = u; ListView1.DataBind();
I have two related ddl's on an updatepanel and would like to put the result of that query on a textbox... So pretty much using this kind of query on Sqldatasource

I would also like to specify which assignments should be displayed in the grid. Btw, my LINQ entities are extended to allow me to write/get studentx.Assignments or assignmentx.Students.

I have to create a simple application which scans, displays and stores the info from a barcode. I have been able to sort the scanning and display part of this application but I need to know how to store the infromation entered into a textbox to a database and then be able to display the stored data as a list at a later stage.E.G. Once the "STORE" button is clicked, the information/text within the textbox is stored to a database. Once the "VIEW STORED DATA" button is clicked, the stored information in the database is displayed as a list.I am a complete beginner when it comes to creating web applications using asp.net. Also, the type of database to use (i.e. sql, wamp.etc) and how to link it to my application is also puzzling.

I have two SQL Server tables with Primary Keys (PK) and a Foreign Key (FK) linking the two tables:
1) Table "Order"
OrderID, int, PK AddressID, int, FK ...
2) Table "Address"
AddressID, int, PK City, nvarchar(50) ...
Then I've created an (ADO.NET) Entity Data Model out of those two tables. Now on my (ASP.NET) webpage I put a GridView with an EntityDataSource. In my GridView I want to display two columns:
OrderID City (belonging to that order and linked by the AddressID-key) How can I do that? My problem is: When I configure the Entity Data Source I can select an "EntitySetName" which can be either "Order" or "Address" but not both, nor can I select any kind of relationship. If I select "Order" as EntitySetName then in the GridView I can add the columns
OrderID Address Address.AddressID
Adding the column "Address" displays empty cells. Adding "OrderID" and "Address.AddressID" displays the expected IDs. But how can I add the "City" of the related address to my GridView? Edit: Clarification:
The Entity Framework has created a class "Order" and a class "Address" corresponding to the database tables. The class "Order" has a reference to an "Address" object as a navigation property, corresponding to the 1-n relationship between Address and Order table. Basically I want to have a column in my GridView which displays Order.Address.City. I have tried to add a bound field with "Address.City" as data field to the GridView but it results in a runtime error ("no such property...").
After saving image in db how can we retrieve it in gridview like thumbnail size image and by clicking on image in gridview its open as preview. How can we do this in asp.net using c#.
I have a table with product codes and items related to the codes.
TABLE 1
Product Codes | Item Number
RP WOEWPOI
Y OWRT0W
ZZ LDSFLSGKK
I have created a second table which contains a product group. This table holds information on where the Product Codes belong. I'm not sure if I have designed this table correctly.
My aim is to create a report in where I know a particular item is related to a certain Product Group. I'm not sure if I'm going about it the right way though. I need to know how to link it if it's one to many or many to many or...I really don't know.
