What is the difference, if any, between letting the framework do the modelbinding to a parameter:
[Code]....
vs. invoking the modelbindng manually/explicitly in the action method:
[Code]....
Is there any difference(s)? E.g., does the framework use the parameter name (m) during the modelbinding in the former method in some way that it might not do in the latter way?
I got a ActionResult method that returns a View that it populates with a class object.
On that view I got a submit button and I call another actionresult method that takes the class object as an parameter.
I understand that you have to implement a modelbinder for that class if you need to retain the values.
But i dont understand how it saves the values from previous methods.
For now i put the object in a session object, but i have a book(Pro ASP:NET MVC Framework" from Apress, and in there they say that you dont have to put anything in a session object. But they dont show how else to do it.
Does Modelbinding increase performance that much? I have a large table which I have split into 4 details/edit screens, and want to load only information that is needed on the particular screen.
View 1 RepliesI am having a table in which i`m dynamically creating and deleting rows. How can I change the code such that the rows be added and deleted and the model info property filled accordingly.
Bearing in mind that the rows can be dynamically created and deleted, I may have Info[0], Inf0[3], info[4]... My objective is to be able to bind the array even if it`s not in sequence.

I have an MVC3 with EF4 project. I have a screen for order .Order has 2 id's inside it for Billilng and Shipping AddressID .When I go and create a new order these fields render as single textboxes as Ids'Question is how can I render full address textboxes (addressline1,city,state,zip etc) do I have drop in the html markup for them? In that case while capturing the data back I willl have to go with classic way of retrieving name/value pair and then do insert into address bring back that identity and update the order record...?
Create(int customerID,FormCollection fc){}
So the main question is how can I do ModelBinding with foreign keys?
I have the following codes and the test value is always null in the controller after the post. What is wrong and how can I correct it?
The values of Color, Size, Clothes are posted with the expected values. Though Data.test contains the values, I`m having Object {test=}, in firebug and test is null in the controller. why is that so?
[Code]....

Perhaps should have posted this with my previous question, but now that I figured the problem, it might be better to create a new one.
My viewmodel is a custom type (say Person) and one of it's members another custom type (say "EmploymentStatus").
I got a list of "EmploymentStatuses" which I convert from IEnumerable<EmploymentStatus> to a SelectList
[Code]....
and I use this list in my View (Strongly typed using PersonModel)
[Code]....
All fine. The problem is that my controller expect a person object and when it does validation, it tell me that the employment status selection are not valid. Obviously because a EmploymentStatus object are expected whereas the View return a SelectListItem.
Let's say I have a property and a textbox on a view
[Code]....
I don't understand why each time I use the modelbinding validation like this
[Code]....
I still get the error displayed, But this time only by Html.ValidateSummary(). the textbox is not highlighted anymore and Html.ValidateMessageFor() doesn't display any message at all.
Is there something I should do the solve this problem? It's important because I have many form that user need to fill out. It's important to highlight the textbox to make it obvious to them.
I just want to know what are the main differences between ADO.NET Entities Framework and LINK to SQL ? It is okay to use ADO.NET EF for a simple website ? What advantages each have?
View 3 Repliesknow if the followin is supported in .net framework 4.0?I have a sql stored procedure with one of its parameter as Hierarchy data type( i suppose its a table valued parameter).. trying to drag this stored procedure onto my linq design studio is not being allowed?
View 1 RepliesIs this possible?
using (Entities db = new Entities())
{
LoadDropDownList(ddlFirst, db.MyTable , (bool)(myMember.Id == 0), (int)myMember.RevenueRangeID);
LoadDropDownList(ddlSecond, db.OtherTable , (bool)(myMember.Id == 0), (int)myMember.OtherID);
}
I am stumbling on what the type of the second parameter should be - I am essentially trying to pass in the Entity-Framework 'table' into a generic routine that loads the DropDownList with data from the 'MyTable' table using custom logic/filtering.SInce I do the same thing about 6 times for 6 different dropdownlist/table combos I wanted to use a generic function to accomplish this.
I need to check if any rows are returned in a QueryString here's what I have so far.not sure what code to put to see if the row count is greater than 1
private void BindDataToGrid()
{
//MessageBoardEntities3 is ThemeableAttribute connection string name
int TID = Convert.ToInt32(Request.QueryString["ThreadID"].ToString()); // if Post ID is int
var context = new MessageBoardEntities3();
gvPosts.DataSource = from p in context.Posts
where p.ThreadID == TID
select new { p.Post1, p.PostID };
gvPosts.DataBind();
lblNoPosts.Text = "No posts found for this thread.";
}
I can't let my button's OnClientClick fire if the requiredFieldvalidator fails. I created a webform that defines my problem. displayMessageClient() will always run whether
RequiredFieldValidator passes or fails.
I want to run displayMessageClient() only if the RequiredFieldValidator passes

I've built a web app to practice what I'd learnt about asp.net and css. The problem I've come across is that if I were to sell it to a customer how would I be supposed to allow the customer (admin) to edit contents e.g., posting new blogs, uploading photos? look I'm not going to build in a visible 'sign in | sign up' on the header for example, because the website is a personal one and just customer (admin) is supposed to edit it. To be straight I need to know what actions I must take to do to let one SINGLE customer edit his web without dealing with technical codes (knowing what a content place holder is and etc.)

View 1 RepliesCurrently i'm saving pictures to our sql server db. A user can go to a clients info page and click an id card image to open a new tab or window and see the picture saved for that client.
What I would like to do is when a client info page opens a small version (thumnail) of the picture to display and let the user click the thumbnail to open a bigger icture in a popup window.
On my website, registered users can make a profile about themselves suchas name, Favoirite color, hobbies, etcI have a DataTable called User which hold this information.also there are other datatables for Hobbies and Colors which list all possible options.To let the user update their choices I have a FormView in Edit mode on the aspx page whichis binded to the UserTable with a GetProfileByUserId Method and objectdatasource.
Within the formview, i have added drop down lists that are binded to the hobbies and Colors tables so they can edit their previous selection.On clicking Uodate update formview calls an Update Method that adds new selections to the User databaseNow I have two questionsIs it possible to show in the dropdown list the selected value that the User has already made?If the user only changes hobbies and not colors when they click update will a null value be passed into the data table for colors that replaces their previous selection?
In my opinion, these architectures have some differences, such as:
1. 3-layer is a linear architecture, but MVC is a triangle architecture.
2. Presentation Layer of 3-layer includes View and Controller of MVC? And Model of MVC includes Business Layer and Data Access Layer of 3-layer
I think 2 differences above are not obvious or are incorrect!

I think that I am confuse here. Now I am using WebParts as they being used on 2.0 framework (like they are using on TheBeerHouse kit)
But in most of the forums they talk about SharePoint. Does sharepoint means webparts as I know them, or this is a new version of the webparts?
