MVC :: RenderAction With Lambda Expression In MVC 3.0 Preview 1
Sep 29, 2010
i have the following, which works:
@{Html.RenderAction("Detail", "Help", new { pageName = "press" });}
But instead i'd like to use a lambda expression to get away from the string bits. I tried using the following (which is the nearest approximation i could figure based on my limited knowledge of the engine):
@{Html.RenderAction<HelpController>(x => x.Detail("press"));}
But i get the following error:
The non-generic method 'System.Web.Mvc.Html.ChildActionExtensions.RenderAction(System.Web.Mvc.HtmlHelper, string, string, System.Web.Routing.RouteValueDictionary)' cannot be used with type arguments
However, i'm reading in the Apress MVC 2.0 book that it is in fact declared as a method that takes type arguments. Am i missing an assembly reference, or has it not been included in the MVC 3.0 Preview 1 build?

I have two lists. lst contains ViewState Data i.e All the records of the gridview & second lstRank contains the list of integer(i.e ID) for only those records which are marked as checked (i.e Gridview contains a columns for checkbox). Now i want to update the lst bool status depending upon integer ID of lstRank. How it can be achieved by lambda expression
List<Tuple<int, string, bool>> lst = (List<Tuple<int, string,bool>>)ViewState["gvData"];
List<int> lstRank = gvDetails.Rows.OfType<GridViewRow>().Where(s => ((CheckBox)s.FindControl("chkSelect")).Checked)
.Select(s => Convert.ToInt32(((Label)s.FindControl("lblRankCD")).Text)).ToList();

I Use entity framework 4.
Here is my model
Language
LangID
LangName
Product
PrdID
IsActive
ProductText
PrdID
LangID
Text
Category
CatID
IsActive
CategoryText
CatID
LangID
Text
Each time I want the text for one of these model, I execute this lambda expression p=> p.LangID == 1
Is it possible to create a generic lambda expression function that all of these model can use.?

I did a small experiment to test whether lamdba expression can retrieve faster results than foreach statement. but, Lambda failed
[Code]....
why lambda is slower than foreach. This may be a drawback of lambda expression

I am selecting the checked rows from Gridview. To achieve this i have written a lambda expression using dynamic keyword.
var dn = gvLoans.Rows.OfType<dynamic>().Where(s => s.FindControl("chkSelect").Checked == true).Select(s => s.FindControl("lblCD")).ToList();
I want the output of this in List. Can it be achieved by extending the query or i have to write foreach statement.

I need to get two fields from a database table (retrieved using linq-to-sql), one field is a datetime (and is a fixed field) and the other is always a decimal, but the field can be different.
The table holds currency data which is processed twice a day and in different currencies so could have fields such as AM_USD, PM_USD, AM_EUR etc. And I need to get data such as a list of the date against PM_USD or the date against AM_EUR.
I would like to be able to call the data using a lambda expression for example (this is a stripped out example):
data = TableData.Select(x=>new {x.DateTimeAdded, x.[**field name as string**]});
I have been trying to write a function to do this, and am failing dismally.
The closest I have managed is:
private Func<TableData, KeyValuePair<DateTime, decimal>> CreateSelect(string FieldName)
{
var parameterExp = Expression.Parameter(typeof(TableData), "sel");
var dateParameter = Expression.Parameter(typeof(DateTime), "DateTimeAdded");
var fieldParameter = Expression.Parameter(typeof(decimal), FieldName);
ConstructorInfo constructorInfo = typeof(KeyValuePair<DateTime, decimal>).GetConstructor(new[] { typeof(DateTime), typeof(decimal) });
NewExpression constructExpression = Expression.New(constructorInfo, new ParameterExpression[] { dateParameter, fieldParameter});
var lambda = Expression.Lambda<Func<TableData, KeyValuePair<DateTime, decimal>>>( constructExpression, parameterExp);
return lambda.Compile();
}
Which fails with "System.InvalidOperationException: Lambda Parameter not in scope".
I'm sure I missing something obvious, or going about it wrong way.

I'm new to LINQ and EF and I seem to be having trouble working this out.
I have a many-to-many relationship between my Location and Region tables. When adding or editing a Location, my interface allows the user to check any number of related Regions. If they click OK, I need to add any new relationships that were checked, and delete any existing relationships that have been unchecked. My basic code is shown below.
However, this code doesn't work. Lower down, the line location.Regions.Contains(region) returns false even when the location already is related to the region. The issue appears to be because the region is from my populated listbox that was initialized earlier and is no longer part of the current EF context. But if I try and add it, I get an error that there is already a Region with that ID.
It seems like what I want to do is change this line to something like location.Regions.Contains((r) => r.RgnID == region.RgnID) so I'm only testing for a particular ID. But this gives me the error "Cannot convert lambda expression to type 'TrailCalendar.Region' because it is not a delegate type."
I don't understand this error but, either way, I'm not sure how I can test if the relationship already exists without reloading a bunch of data, which I'd like to avoid.

I am new to LINQ to XML in .net(C#, asp.net). I want to know more about Lambda expressions. I am using Lambada expression with the following query.
count = FieldRoot.Element("USER").Element("MM")
.Descendants("MMMS")
.Where(a => a.Attribute("ID").Value == MID)
.SelectMany(b => b.Descendants("ABC")).Count();
how the Lambda expression work specially in case of parameters (in the above case a & b) ? What is the basic concept of parameters in Lambda expression ? Can we use the names of the variables defined outside of the query instead of a & b ? which elements a & b represent in the above case represent ? Can we pass parameters from outside in the query ? If we can pass parameters from outside query then how it will be done? If you give me any other example instead of the above query to understand the concept of parameter in Lambda expression.

I'm using MVC 2 and MVC Futures 2.0.50217.0.
I started with a view which repeatedly calls RenderAction(...) to include some external content implemented by another controller in my application. This is from the containing view:
[Code]....
The subModel objects are instances of the model for the MyController.MyAction view which has some Data Annotations validation attributes upon it. MyController.MyAction checks the model state is valid before it renders its view and chooses a view appropriately. This works fine.
However, if I use the MVC Futures' strongly typed helper to call RenderAction like so:
[Code]....
...then the validation is not performed. Or at least, the model state does not indicate that the model is invalid.

var pq = attributes.SingleOrDefault(a => a.AttributeName == PasswordQuestion").AttributeValue;
The above code will throw an error if null. What is the best way to handle this?The below code would work, but I can't help but feel there's a more graceful way?
var pq = (attributes.SingleOrDefault(a => a.AttributeName == "PasswordQuestion") != null) ? attributes.SingleOrDefault(a => a.AttributeName == "PasswordQuestion").AttributeValue : null;

I read many posts about outputcaching element in asp .net MVC, but i have one question.My architecture is :1 master page, 1 page (especially news information), and a few other controls like LogOnUser / Fixed status bar etc...I want to have my news cached cause there are three query to entities, but i need too the title for SEO of my master page (title is included in a contentplaceholder in master).I tried to use renderaction outputcache but it is not possible to retrieve the title from the renderaction. Have you any idea about this problem ?Maybe it's preferable to use a general outputcache and use a substitute from dynamic data, but i don't know if it's a best practice or not.

I write inline expression and binding expression in the server head section:
[Code]....
[Code]....
But both kinds of expression aren't parsed or executed except the ResovleUrl menthod. The html renders like this:
<head><link rel="stylesheet" type="text/css" href="<%= Request.ApplicationPath %>themes/style1.css" /><link rel="stylesheet" type="text/css" href="<%# Request.ApplicationPath %>themes/style2.css" />
<link rel="stylesheet" type="text/css" href="/themes/style3.css" />
<script type="text/javascript" src="/js/jwork.js"></script>
</head>
As I know, the inline expression in the attributes of server control can't be parsed but the binding expression should if we invoke the DataBind method. But the above case breaks the rule.

I'm trying to use the validator to work on a email form to ensure that they enter a valid from email address. That part works. I also want to add to the expression the text that I pre-populate in the txtbox ("Enter your email address") so on postback, after sending the message, I can clear the fields and repopulate that box.
How do I add that wording to the current expression: w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*

We are using renderaction provided by MVC futures. We've noticed that HttpExceptions in child action methods are not propagated to the parent action. Even though a fragment has failed, we still see the parent request resulting in a 200, and this throws our error handling for a toss.

Just wanted to get clarification that methods like HTML.TextBoxFor() exist ONLY for the benefit of compile-time parameter type checking.
From my experimentation, these appear to ONLY accept a simple "expression lambda" syntax, which simply provides reference to a member property, and will not allow more robust use of "statement lambda" syntax. Other places in the .NET framework where lambda's are used, "statement lambda" syntax can be used, such as :
( x => { x += 7; if(x < 9) return x * 3; } )
... in effect, multiple statements of "in-line" code.
The type checking benefit is great - I just wanted to understand if there is additional capability which I have not recognized.

I am using Regular Expression validator for a text box. The below is working fine.It is not performing validation when I enter values like 0000..001.How can I modify validation expression? But it would allow values like 100,...5000 i.e zeros after a number.
<asp:RegularExpressionValidator ID="reg2" runat="server" ControlToValidate="rng2"
ValidationExpression="^[0-9]+" ErrorMessage="*Please Enter a Valid Number for Second Range."

I am using MVC 2 and am having problems getting the OutputCache to work. My ASP.NET website has Several Views and a View Master Page. On my View Master Page I have a Menu on the left hand side displaying navigation links (implemented using JQuery).
I have implemented the Menu as a PartialView and I call this PartialView from my MasterPage using Html.RenderAction. This all works fine, my controller fetches the data from the database and the PartialView is populated.
The problem is I want to cache the Menu data since it's consistent on all pages. Yet when I add the OutputCache parameter to my Action it has no effect.

i have this (simple) code
<% Html.RenderAction("Version", "Generic"); %>
in my masterpage of my asp.net mvc 2 app. This method returns the version of the application.
i also have this code in my controller:
class GenericController : BaseController
{
[ChildActionOnly]
public string Version()
{
try
{
string assemblyFile = Assembly.GetCallingAssembly().FullName;
FileInfo fi = new FileInfo(assemblyFile);
string version = fi.LastWriteTime.Year.ToString( ) + fi.LastWriteTime.Month.ToString() + fi.LastWriteTime.Day.ToString();
return version;
}
catch (Exception e)
{
return "1.0";
}
}
}
Now i get this error:
Execution of the child request failed. Please examine the InnerException for more information.
and the innerexcpetion is:
{"The controller for path '/Account/LogOn' was not found or does not implement IController."}
What i was thinking is that maybe the code can't execute because the user is not logged on yet, and tries to redirect to the logon method etc.
So the first thing i was thinking is to grant access in the web.config (like i do with the directory that has the css and images in it, it should also be accessable when you're not logged on:
<location path="Content">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
but what is the path for this (version) method ?
(or maybe there is another reason for the excpetion.
