C# - Handle Foreign Key For Optional Field?
Mar 23, 2010
What is the best way to handle following situation? A dropdown(for master table) is optional in a particular form. But, In database table the field is constrained with foreign key. If user don't select from dropdown then It creates problem because of foreign key. One solution is to create default option in master table and use it in case of blank selection. but in dropdown, we need to handle this to show on top. Is it perfect solution?

I've already implemented URL routing in my app but there are cases where I may or may not get a paramter. In particular, I'm trying to come up with a good way to handle multi-language support. For example, if my regular URL is /SomeCategory/Friendly-Topic-URL, I want to have an optional language selector at the end but I'd like to be optional. So, if I get /SomeCategory/Friendly-Topic-URL/es, that should bring up the topic in Spanish but if get nothing, that should bring up English.

Should my SQL query look like

how to handle foreign keys with Entity Framework, when editing or adding a new record. For example, I have a person table, which has a timezone_id linking to my timezone table.
But the model seems to not include timezone_id. I see it's a new way of doing things, but ... how do I store my record?
My method:
[code]...
I can't do u.timezone_id = timezoneid;
I only have u.timezone (which seems to be the actual entity), and u.timezoneReference, which I am not sure what to do with.

I have made an entry field required somehow but I'm not sure how. When editing a tag, the tag owner entry field should be able to be empty.I have set "allow nulls" in the database table:Does anyone know how I can fix it? To be clear, I want the above form to be submitted without requiring a value for tag_owner.

I have set up Membership and Roles and can create users and login using the ASp Login control. However I need to associate users with customers (in a Customers table in the database) and display content according to the customer that the user belongs to. Is the best way of doing this to create a foreign key field in the aspnet_Users table relating back to Customers table which would have to be updated manually after creating the user or is there a better way?

Employee Table : ( EmployeeID,EmployeeName,... Etc )
Bonus Table : ( BonusID,EmployeeID,BonusDate,Bonus Reason,... Etc )
I wanted to list the bonuses in a gridview, so i made a query to return list of bonus records and my data access object returns the result set as Bonus business object ( generic collections of bonus BO ). i have bind my gridview with the bonus collection.
now my problem is that collection has the property "EmployeeID" and it will be displayed but instead of showing EmployeeID, i wanted to show Employee Name in that grid. I have a gridview where i want to list the bonus records ( bonus ID, bonus date, bonus description, employee ID) ,

Trying to figure out how to handle data returned for a site search from a description field. I don't think I want to display all the text from the description field, but I also don't want to "chop" a word in half. How do I get the first 100 characters, plus a few extra letters if needed to prevent a word from being chopped in half. In some cases, the description field is less than 100 characters, so all the text will be displayed. However, if the description does need to be chopped at 100, I'd like to finish the word and add ... to indicate that there is more text.

I have the following scenario: my website displays articles (inputted by an admin. like a blog).So to view an article, the user is referred to Home/Articles/{article ID}.However, the user selects which article to view from within the Articles.aspx view itself, using a jsTree list.So I what I need to do is to be able to differentiate between two cases: the user is accessing a specific article, or he is simply trying to access the "main" articles page. I tried setting the "Articles" controller parameter as optional (int? id), but then I am having problems "using" the id value inside the controller.

Is it possible to do an optional join as follows?:
private void OptionalJoin(string phrase)
{
from t in db.Table
// (if phrase != string.Empty then) join t2 in db.Table2 on t.Id equals t2.Id
select t
}
Although I'm aware that I can copy/paste this and move the conditional logic outside the query, the query is ~200 lines and there are 4 different optional joins I would like to incorporate, so it would get messy and be difficult to maintain. I'm looking for a clean, streamlined way to do this.

Wondering if you could give me a nudge in the right direction. I'm working on an app where I need to validate a field for a correct URL. However, this is an optional field and may be left blankI was just wondering, how can I bypass the validator if the field is null.

I have got a problem about setting the optional parameter to NULL in sql sp. Initially I set all the parameters null in the sql sp. That's OK. But I would like to set the parameters to Null again if a particular parameter has a value of - 1 by using the "IF ELSE" statement block. However, the problem was that I was unable to set the parameter to NULL in the IF ELSE statement. So please correct my IF ELSE statement in the store procedure. This is really urgent and important for my project.

I have a timespan ts that has mostly minutes and seconds and sometimes hours. I'd like to format a string that'll give these results depending on the data
3:30 (hours not displayed, showing only full minutes)
13:30
1:13:30 (shows only full hours instead of 01:13:30)
So far I have
string TimeSpanText = string.Format("{0:h\:mm\:ss}", MyTimeSpan);
but it's not working.

the very famous actionlink:
<%: Html.ActionLink("Back to List", "Index")%>
Now, this link is in my Details view. The Index view is a search page. The url of that looks like this:
[URL]
as you can see, quite the amount of parameters. Obviously I want to keep all these parameters when I return to the Index page, so I need to add them in the ActionLink.
now, I'm tired of doing that manually, it's ok for 1, but not for 6. This should go a lot easier.
question: How do I return All parameters of the current url into the actionlink as optional routevalues.
I've been looking to Request.QueryString. It has to be something with that. I was thinking of writing some static method in Global.asax doing the job but no luck yet. maybe there is an easy way to do this which I dont know about??
Edit: This is what I came up with (which works)
