MVC :: Creating A Complex Form With C#?
Feb 10, 2011
How can I create a form that creates or updates a complex type that takes a form like:[Code]....
I would like to either create two forms one for tblstudent and one for tbldata and tblStudata or create one form for all three and give the illusion of multiple pages. I came across an old Railscast that talks about virtual attributes and a helper called fields_for which helps you switch between model contexts in a single form. Is there a way of achieving this kind of functionality with C# MVC 2 or 3?
If this sort of thing is not possible how else might I be able to handle create/update scenarios without defining two actions amd voews for each table entity I need to work with or god forbid separate controllers?

I have a form which I use to create an issue. WHen you post the form, the form elements are that of a custom DTO. The DTO is then used on my POST method to create the new entity. That all works fine.
However, I want to add the functionality to add multiple issues at the same time from the same view. In effect, the user would click something like 'Report Additional Problem', and an extra set of form fields would appear (I will like use jquery for this, which I don't have an issue with). However, even with just leaving one set of form fields, the user should still be able to create just one issue. But if I habve my post method take a list or array of my DTO, it doesn't work.
Here is the post method before editing:
[Code]....
What I want to do is for this to take an array or list of NewIssueDto. I would then loop through each one in the list and create a new issue from it.

I'm trying to set the default button to my master page for logging in.
Basically I've got a master page, with a LoginView in it, with a Login control in it, With a button in it... When you press "Enter" I want it to use that as the default button.
(structure in sudo-code if it helps)
BODY
Form ID=Form1
LoginView ID=MasterLoginView
AnonymousTemplate
Login ID=MainLogin
LayoutTemplate
Button ID=LoginButton
I know I've got to use .FindControl("") but as much as I mess with it I can't seem to get it to hook to the button.

So part of my web app centers around this very important form which is used to create a form. Its like google docs form. The user keys in a type (checkbox, textfield, numericfield) and a label and slaps it into the system, and it generates a form somewhere.
Its a little more complex than google forms, the field types are complex and theres a lot more to that form (It happens to be a form generator for a finance plan)
The app is asp.net, I was thinking of using jquery and jquery's own ajax methods to post the data, but I think it would just turn into a very hairy situation, I then thought silverlight, but Ive never done silverlight before but I am an experienced .net guy.
So what do you guys think, will silverlight be too tough for a first timer for this kinda thing? Or should I stick to jquery. Plus points for silverlight is its an inhouse lan app and this particular page will be used by people with very high bandwidth.
Also I'm on .net 4 btw.

What I want to achieve is the ID of the property: item.Item.ID to be bound to the ID from the (route)URL. However I can't get it to work. I tried using [Bind()] attribute.
I fixed it now using a hidden field in the form like so:
<%= Html.HiddenFor(model => model.Item.ID)%>
However this feels a bit icky. I'd like to know if there is a better cleaner way of doing this?

I was developing a project. It was running fine. But suddenly it shows the following error:
Quote:
An error occurred creating the form. See Exception.InnerException for details. The error is: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))
But in the meantime I have not change a single line of code.

I have a form with a bunch of labels and images on it. Is there a way I can capture parts of that form into an images file (jpg/bmp, etc)? Ideally I could specify the x-y coordinates, and save that to a jpg.

I'm not sure where this should go (I don't know whether it's a database problem, or a code problem), but I think it's a code problem, so I'm posting here.
I'm working with a database that is storing images (actually, it's a modified version of the AdventureWorks database from Microsoft), and I'm creating a form that will let you upload a file. I've got a business object based on the table that I'm using (Production.ProductPhoto) and I'm using two stored procedures to either get (Production.ProductPhoto_Get) or add (Production.ProductPhoto_Add) an entry from/to the table. The image is being stored as a varbinary field in the database, and a Byte() in my business object.
The problem I'm having is that when I'm adding a new entry and uploading a file, the length of the file uploaded is correct (so I assume everything is going smoothly), and it gets passed along to my ProductPhotoProvider DAL class where I create a DbCommand and add the parameters for my stored procedure. The information is all added to the database successfully, and I'm returned the identity of the new entry as expected -- however, when I try to read this image back, it seems that the length is 1. I've put in break points and stepped through everything, and I don't know what's going on.
I think that I know my ProductPhotoProvider class is at least reading things correctly -- I can display other images from the database (that came with the database, that is) just fine. Mine just all come back with a length of 1.
I'm just hoping someone knows what the hell I'm talking about; I have a lot of programming experience, but this is my first major venture into ASP.NET. I have no idea which parts of my code are relevant, so I'll just post my Add and Lookup functions for now?!
[Code]....
My ProductPhotoProvider class is based off of an abstract class called AbstractDALProvider (which I can also provide if needed). I can provide the rest of my project, if needed, too.
Oh, and for good measure: I was told that when you used to store images in Microsoft Access, there was some sort of problem when retrieving the data and you'd have to strip the first 72 bytes of data from it, or something. I can only assume that this is not a problem here, because I have no problem displaying other photos that were not created by me.

I created tracking software, and now I need to create hundreds of web forms with specific names (within the same solution). Can this be accomplished with managed code or does it all have to be done manually? In case you are wondering what this is for - its to do market research using the keywords in unique URLs...so I just need to be able to create hundreds of them at once to hand to my classified ad poster.

I'm trying to devise a form that will allow me to input multiple contacts. It's a pretty long form so far and I want to keep it as short as possible. I was thinking of just having one set of fields for contact inputting which will add this contact to a list box or gridview but I'm not sure that is the most elegant solution. Could anyone else point me in the right direction to something good I can use?
I'm writing in HTML / asp.net / javascript.

So I'm attempting to limit user's access to my database through the web. I have a registration form that asks the user for a name and password, then verifies this against a DB. In order to prevent DB overload, I will limit the user's attempts to 10 in 10 minutes. This is how I am trying to solve this, but cannot verify that i'm using the right approach.
Code:
Dim timeout As Integer = ConfigurationManager.AppSettings("timeout")
Dim userIPkey As String = Me.Context.Request.ServerVariables("REMOTE_ADDR")
Dim i As Integer
If HttpContext.Current.Cache(userIPkey) = Nothing Then
i = 1
[Code] .....
For some reason I can hit the service with a for loop and get to the DB every time. If I try doing this through the browser while debugging the webpage, I get the right error message after 10 attempts, while on the server, or through a reference to localhost I will not get the error message.

I have entries for an enumeration stored inside a database table with only the following fields: ID and Name. I want to show the values stored inside this table inside a DropDownList on a form. The user then chooses a value and submits the form.
I found a way to easily create a DropDownList from an enumeration (although it would probably be best to just populate the DropDownList with the Name fields of all the records in the table). However, I haven't found a way to later bind the DropDownList in the form submission to an integer value to put into the database (FK - PK) with the other form values.
is it possible to fetch DropDownList content via AJAX and have it be put into the DropDownList and into the SelectList in the ViewModel (with both the ID and Name parameters)? I want to selectively fetch content based on an input the user makes and I want the ViewModel to then be filled with that fetched data.

I have tried various techniques that some seemed to have outlined and so far none of them have worked. I have a situation where the Page_Load() needs to build a set of <input id=<dynamic name'>> that are build dynamically inside a <ul>. The form gets created fine but when I click the button and look at the results returned to the server I cannot seem to find the input values. Is there a defined way of accomplishing this?

I'm pretty new at ASP .NET but not to ASP. I've got a form I need to create where I don't know how many entries will be added. It has the following format:
"Age" "Duration" "Period of Duration" "etc..."
Last30Days
1-5 Months ago
6-11 Months ago
Age
Age
Age
etc.
So the Age column always has the first 3 options and then an unknown number of Age values that can be inserted. I've created a table that has the first four fields (Last30days, 1-5months, 6-11months, age) and I was thinking I could just order by those 4 columns for display. The problem I have is I'm not sure on how to proceed. Does anyone have any good ideas on how to handle this situation? Ideally data entry people could use the same form for both entering and displaying the data.

i have following issue: I am creating a new user register form manually without CreateUserWizard control, and all works perfectly unitil I intentionaly (for test purposes) enter existing username (for example BLABLABLA) into username.textbox. After that i get my error message as expected that says "username BLABLABLA allready exist", now when I tray (as a future user who could be in the same situation) to correct the username and enter another one (for example TRATRATRA), it still gives me this error "username BLABLABLA allready exist!" This is the second day that I'm traying to solve this!
Here is a part of my code:

I have created and application which contains a gridview that is populated by an SQL database. I built a function which converts the gridview into an excel file and stores it on the server.
I would just like to know how I can write an executable script(which I will set to run at a certain time on the server) that will access the gridview in the .aspx file containing the gridview and run the convertToExcel() function located in the .cs file attached to the .aspx file and then close.

OK, so I'm trying to create a template item from a web form.
I have referenced this article: [URL] and it exports the template and installs it fine.
When you try and use the template item within a project though it leaves the inherits="_Default" in the page directive like shown below:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="FormTemplateDev.aspx.cs" Inherits="_Default" %>
So it thinks all the new template items use the original form name pre-template generation. This is an issue in the code behind too as shown here:
public partial class _Default : System.Web.UI.Page
I have seen example of passing paramater strings through but havent managed to get anything to compile. I found something like below:
public partial class $safeitemname$ : System.Web.UI.Page
This was the link to the list of available template parameters i found:
Project Template Parameters
