C# - SiteMap Navigation And Query String?

Jun 24, 2010

Currently I am trying to figure out how I can add dynamic query string parameters to my sitemap navigation menu. For example, the user chooses the source and edition he wants to work with. I have a simple sitemap that creates navigational links but the parameters the user chose need to be passed in the query string. The default map looks like this:

<siteMapNode url="" title="" description="" >
<siteMapNode url="~/Image.aspx?location=Our Products" title="Our Products" description="Our Products" />
<siteMapNode url="~/Headline.aspx?location=Our Authors" title="Our Authors" description="Our Authors" />
</siteMapNode>

Now the links will need to have the parameters added dynamically depending on what was chosen by the user. For example:

<siteMapNode url="~/Image.aspx?location=Our Products&Source=12345&Edition=asdfff" title="Our Products" description="Our Products" />
<siteMapNode url="~/Headline.aspx?location=Our Authors&Source=12345&Edition=asdfff" title="Our Authors" description="Our Authors" />

Linq Query Returning Less Records Than Sql Query?

Mar 19, 2011

I am facing a big problem with simple linq query.. I am using EF 4.0..

I am trying to take all the records from a table using a linq query:

var result = context.tablename.select(x=>x);

This results in less rows than the normal sql query which is select * from tablename;

This table has more than 5 tables as child objects (foreign key relations: one to one and one to many etc)..

This result variable after executing that linq statement returns records with all child object values without doing a include statement.. I don't know is it a default behavior of EF 4.0 . I tried this statement in linqpad also..but there is no use... But interesting thing is if I do a join on the same table with another one table is working same is sql inner join and count is same..but I don't know why is it acting differently with that table only.. Is it doing inner joins with all child tables before returning the all records of that parent table?

Linq Query - How To Select Inner Query Into List

Oct 17, 2010

I am writing a linq query to select a blogpost,

[code]....

The blogpost i am testing got 3 tags attached to it. The table structure is:

(table)BlogPost -> (table)BlogPostTags <- (table)Tags

So the BlogPostTags table only contains 2 fields, BlogPostID and TagID.

When i run the query above i get 3 results back. Same blogpost 3 times but with 1 tag in each. It should return 1 post with 3 tags. The problem lies in the Tags query above.

Web Forms :: How To Set Properites Of Child Controls

Nov 11, 2010

Is it possible to someshow select "child" controls of an <asp:Table> control so that I can view and set properties of the "child" control while in designer view? Its a real pain to have to edit properties of a child control in the source view. What I ultimately seem to end up doing is having to place or move any controls inside an asp:Table that I want to set properties on to the "outside" of the table and set all the properties on the control. After all the properties are on set on the control, using the designer,I can move it back inside the asp:Table. This is not the most troublesome of options but it would be nice if you could somehow set the properties of child controls using the designer.

ADO.NET :: LINQ Entity Framework Query - Construct "nested" Query?

Jan 22, 2011

I have a web app for our golf club. When I compute handicap index for each golfer, I have to select the most recent scores and then a subset of those scores depending on how many rounds of golf the golfer has played. All the scores are entered into a single SQL Express table called "Rounds". Verbally, this is what I'm trying to do:

1) select the twenty most recent golf scores (sort on date descending, "take(20)") [if less than 20 records, then select all available];

2) for this set of records, select the 10 lowest scores (or smaller number if golfer has less than 20 rounds);

3) compute the average round differential for the subset of records, etc. to calculate handicap index (this step is working ok...)

My current VB code has this LINQ query (which is flawed -- it selects the lowest handicap differential scores of ALL records for the filtered user):

[Code]....

How do I modify this query to accomplish items 1) & 2) above? It seems this should be simple, but my experience with queries is still limited.

ADO.NET :: Not Sure How To Do This Query In Linq To Sql

Sep 12, 2010

I need to figure out how to express this in linq to sql:I have one or more records that contain what is essentially a wildcard sql parameter, like '100_-___-2', which should match 100[any 1 char]-[any 1 char][any 1 char][any 1 char]-2, for example. Each login will have one or more of these 'datamasks' associated with it.I need to write a query in linq to sql that does something like:

select * from something
where fieldA = 'someValue' or fieldB = 'someValue'

so far, simple, but I also need to restrict the returned records to only those that match the user's 'datamasks'. I'm not sure exactly how to translate this to linq to sql... here is what a working query *without* the datamasks part looks like:

[Code]....

I need to tack on the datamasks part... can I do it right there in the same statement? or do I need to do a foreach loop on the datamasks records and append a new && condition for each one? hmmm... just thought of that as I was writing this.. I'll try that out. But I'm posting this anyway for more input... I guess that would look something like:

foreach (string mask in datamasks)
{
query = query.Where(item =>
System.Data.Linq.SqlClient.SqlMethods.Like(item.AccountNum, mask));
}

would that work? would each additional 'where' condition be 'appended' to the existing query definition?

C# - Test If Linq Query Went Through?

Mar 15, 2011

This is my code from my controller:

MGEntities db = new MGEntities();
[HttpPost]
public ActionResult Register(RegisterModel model)
{
if (ModelState.IsValid)
{
// Attempt to register the user
MembershipCreateStatus createStatus = MembershipService.CreateUser(model.UserName, model.Password, model.Email);
if (createStatus == MembershipCreateStatus.Success)
{
FormsService.SignIn(model.UserName, false /* createPersistentCookie */);
MembershipUser myObject = Membership.GetUser();
Guid UserID = (Guid)myObject.ProviderUserKey;
MyProfile profile = new MyProfile();
profile.Address = model.Address;
profile.City = model.City;
profile.Zip = model.Zip;
profile.State = model.State;
profile.UserId = UserID;
Debug.Write(profile.State);
db.aspnet_Profiles.Add(profile);
return RedirectToAction("Index", "Home");
}
else
{
ModelState.AddModelError("", AccountValidation.ErrorCodeToString(createStatus));
}
}

This is my MyProfile Class:

namespace MatchGaming.Models
{
[Bind(Exclude = "ProfileId")]
public class MyProfile
{
[Key]
[ScaffoldColumn(false)]
public int ProfileId { get; set; }
public Guid UserId { get; set; }
[DisplayName("Address")]
public string Address { get; set; }
[DisplayName("City")]
public string City { get; set; }
[DisplayName("Zip")]
public string Zip { get; set; }
[DisplayName("State")]
public string State { get; set; }
}
}

After the linq query is executed, i check my database and nothing is added. I am using POCO for my entities. Here is my class:

namespace MatchGaming.Models
{
public class MGEntities : DbContext
{
public DbSet<MyProfile> aspnet_Profiles { get; set; }

C# - Get The Sql Created By A Linq Query?

Jan 18, 2010

I've been developing a ASP.NET page and have been using LINQ to handle talking to MS SQL server. I'm ok at basic SQL, however I'm a lot better with designing queries using LINQ. I know they are similar but I find it easer to design complex queries in LINQ. My question is this: Is there a way to design a query in LINQ and then get the SQL that it generated? I would like to embed the SQL in a stored procedure since multiple pages (outside my control) will need to do the same query.
