In linqtosql you could do something like:
datacontext.CreateDatabase() to generate a database from the model in sql.
I'm wanting to do the same thing in linq to entities.
Say I have a class MyEntities which inherits from ObjectContect is there a similiar method?

Is this possible? and how do i go about setting it up?

I would like to find out if there is anyone who would know how to read from a database then returns the same number of records that a stored procedure returns and display those records on the webpage there after pass the ID of the record to a variable to another stored procedure that displays the data related to the record that was clicked, I tried doing this in a asp.net repeater but I can't seem to be able to reference the controls inside the repeater.

I'm currently in the process of creating a webshop. This webshop supports theming, but I also want customers to choose a lay-out. I can create multiple masterpages and create a handler to dynamically set the correct master page. But some components, like the shopping cart, are controls which have to be present in the master page and are also used in the aspx pages. The shopping cart control for instance, has an Update method which is called whenever the user adds a product to their cart. So the question is: can I somehow create a default masterpage which has all the components on it, but still be able to create multiple lay-outs. And how should I reference that master page from the aspx pages? I also thought of creating an Interface class which defines the masterpage and it's public components, but I don't know if I can reference an interface from aspx pages.
View 8 RepliesI just read this:
http://www.albahari.com/nutshell/predicatebuilder.aspx
I have a couple questions,
1. is that predicateBuilder the only way to do this?
2. will the following code produce 'AND' or 'OR' connecting these?
foreach (string sParam in sParams)
{
query = query.where(item => item.Whatever == sParam);
}
assume query is an IQueryable<t>. This stucture also dynamically builds the where predicate right?
Could anyone provide me more info regarding this subject because I'm clueless. Any link, tutorial or anything else would be appreciated. The problem is I don't know where to start, but what I have to do is to import data from Access database to very similar SQL database.
View 1 RepliesI have to be able to dynamically change the sproc name that is used in a Linq to SQL query. I see in the dbml designer this:
[Function(Name="dbo.InsertUnknownMessage")]
I have an application where depending on what the user selects run a different stored procedure.
I am using LINQ and am passing the stored procedure name into a sub that will run the stored procedure and return values that I am loading into a DDL.
For example I want to pass the procedure name "GetProducts_Hats" to the sub and not hardcode it.
Protected Sub LoadParamDropDowns(
ByVal SqlObjToExec
As
String )
I am passing the storedprocedure name in parameter SqlObjToExec
so instead of
values = mydb.GetProducts_Hats
I want to code it to be a variable
values = mydb.SqlObjToExec
But the above code does not work.
My situation is as follows:
I do some filtering on the IQueryable<MyType> object using the Contains() function in Linq, which in effect adds: MyColumn LIKE '%@MyParameter%' to the linq requestI want to make the function more generic, which could operate on a IQueryable object of an unknown type. In such case I do not know the type yet, therefore I can not add a standard .Contains() function. All I have present are the IQueryable object, the MyColumn and MyParameter as a string text. I need to be able to add "MyColumn LIKE '%@MyParameter%'" to the Linq object, dynamically ...
How can I write a piece of code that would run the Contains() on the IQueryable, knowing the Column name (as string) and the parameter value (as a string too) - I basically want to add this: MyColumn LIKE '%@MyParameter%' to the Linq where clause.
I have found something doing the .Where() function dynamically, but I do not entirely understand what is happening in there, so I struggle to convert it to Contains():
