I am quite new to LINQ, and I am stuck with this probably basic problem, but haven't been able to find a solution, so I thought I could ask here.
So, I have this repository where I put my functions for data accessing, and now I need to write a function to get all the applicants that have applied for this particular advertisement, and their values too. Now, the values are stored in a separate M:N table, where every row consists of the applicantID,advertisementID and value. I just wanna append the value to every applicant that I show, so that it would look like a Ranking List.
However, I do not seem to know how to select just the name column from the Applicant table, and just the Value column from the ApplicantValue table.
And there's this Iqueryable interface that further confuses me...
Here's my function to get the Applicants only:
[Code]....
Now, if I try to add to the definition of the type two columns, it says that it only messes with types, i.e. one type should be passed. So I figured I would do a ViewModel and then pass it, like this
[Code]....
and then in the function I have no idea how to pass the values:
I am working on a web app for an online photo album. It is the last project in Scott Mitchell's book: "ASP.Net 2.0 in 24 hours".
I am creating a page where users can enter new photo images. The functionality for uploading an image will come later. I am working on just inserting a new row into the Pictures table with an optional category, a required title and a required description.
I am getting an error when I try to insert a new row.
Here is a screenshot of the page with a shot of the dropdown list.
The Categories are user-specific. I am getting the correct values retrieved.

There are two pretty simple database tables involved here.
NOTE: The CategoryID and PIctureID are both autoincrement integer columns.
[URL]
The page uses a DetailsView that uses a SqlDataSource that uses the Pictures table. (The DetailsView's Default Mode property is set to "Insert". The "Enable Inserting" checkbox is also checked.)
The dropdown list uses a dropdown control that uses a SqlDataSource that uses the Categories table.
When the "Insert" button is clicked the CategoryID value associated with selected (Category) Name on the dropdown list will be used along with the Title and Description values to insert a row in to the Pictures table. (If no Category value is selected, then a null value will be used for the CategoryID. This is OK because the CategoryID column in the Pictures table allows nulls.)
My problem is that I am getting this error:
Cannot insert explicit value for identity column in table 'Pictures' when IDENTITY_INSERT is set to OFF.
(FYI: I have the full version of both Visual Studio and SQL Server.)
Here is my source code for the page:

Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?
Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?

View 6 RepliesI need to populate a listbox with the contents of a column in every row of a table. But, the table and its columns are only known at runtime. Once a table is selected by the user, I will know the name and type of the column, whose contents I need to display in a listbox. But, how do you access all rows of a table sequentially so that the contents of the column in each row can be added to the listbox?

View 3 RepliesI can easily create a search that will allow a user to input a single word (or a portion of a single word) into a text box that will search a database column.
But what I want is for the user to be able to type two or three words into the textbox and produce results where just one of the words have to match the contents of the columns cell.
I don't need to be able to do a multi column or table search, and I'm using C# and MS Access.
I imagine this question would have been asked more than a couple of times - but I can't find a decent answer.

I have an asp:Table. Its with is 100%. This table has only one row but 6 columns. The width of first 5 column is fixed at 150px. The last one does not have its Width specified and so it takes up the rest. The whole row has a background. If any of the first 5 column is clicked, the background of that cell is changed to white.In my development computer, the last column has about 250px. Yet in user computer, as the monitor has a smaller resolution, the last column has only 30px or so. User complains it is ugly and wish to merge the last column with the previous one. How to do so?
