MVC :: EF Update Multiple Rows In One Form Post?
Dec 14, 2010
I am a seasoned desktop developer but I am new to MVC, EF and web development in general. I have been following the MVC Music Store tutorial but using my own database and project instead of the one from the tutorial.
My project is a web front end to a configuration database that lets us implement new Markets (a.k.a. Customers) for our IVR. For the View that allows the user to modify an existing Market I use a ViewModel class that has two properties. One property (clientData) is an EntityObject populated from a single row of the Client_Data table. The other property (callflowSeq) is a List of EntityObjects populated from about 40 rows of the Callflow_Sequence table.
The "Get" Edit method of the MarketsEditViewModel displays the Edit View fine but when I modify the data only the Client_Data table gets updated.
Here is my ViewModel:
[Code]....
Here are the Edit methods from my Controller:
[Code]....
Here is my View:
[Code]....
It seems that I can't use UpdateModel() to update the Callflow_Sequence table but I can't figure out how to do it manually.

I am listing about 20 rows, each row represents an Order.Each row needs to have 3 buttons, each button click will perform a different action.I have 3 actions to handle each button post request, I am just unsure how to setup the Html forms for each button.
<tr>
<td>
<form method="post" action="/orders/do1"><input type=button ... /></form>
<form method="post" action="/orders/do2"><input type=button ... /></form> [code]....
Should I create 3 forms for each button, per row in my listing?(that would mean 20 rows x 3 forms = 60 forms on a page)Is that 'ok' to do? (i.e. or is there a better way to do this?)

So, how can i resort the values of a datatable column based on a given value and the datarow id?

</form>
I submit the form from javascript with jquery:
$("#id").val(id);

I have a web form on a web page like this:
<form method="post" action="http://poston.domain.com/" enctype="multipart/form-data"> <input type="hidden" name="function" value="somevalue"> <input type="text" name="username" value="somevalue2"> <input type="text" name="password" value="somevalue3"> <input type="file" name="picture"> <input type="text" name="pictto" value="0"> <input type="submit" value="Send"></form>

I am populating a form trough a query so it will return multiple values, sometimes 5 or 6 or even more.Now when I press submit I need to save each form row in a database.table as a new entry. Other question is I have 3 check-boxes when the submit button is pressed it need to insert the value corresponding to the selected one, how to do that?
Code:
@{
var db = Database.Open("quality");
var selectQueryString = "SELECT * FROM perguntas WHERE chklst_id=@0 ORDER BY id"
var id = UrlData[0];

See what happens when you answer my questions! I come back! No good deed goes unpunished. I've built an Update form where my visitor can update data in dbase. I have a formview with several dropdown lists; none of which will update the table (all the textboxes, checkboxes and even Ajax enabled calendar work just fine). In the form below, visitor selects a CareerCluster from the ddl. Upon postback, the next ddl (pathwayListBox) populates with related data using the CareerCluster.selectedvalue in a query. At the same time, tsaOrgsDropDownList is also populated based upon the first ddl (CareerCluster).
When user selects from the tsaOrgsDropDownList the final ddl (tsaDropDownList) is populated. All this various selecting/populating works just fine on the form. The problem is: Nothing is updated to the table upon clicking the Update button. All other form fields do post as their supposed to except, I have other ddls on the page that are not related to the above series and they won't post either. My thought is that somehow, this is related to the postbacking going on. That posting back is overwriting the selectedValues with null or something.

Im struggling with a way to bind multiple rows of sql data to specific controls, what im trying to acheive is having a list of questions / answers in my SQL db and loading them into my web form to build a questionaire.
The data i load into the form depends on criteria like which questionaire is it (there will be 2 seperate ones) and what language should it be loaded in, this will be controlled using drop down lists and passing these parameters to the SQL select statement.
The problem i have is i am unsure which method to pull the data out of the question column in my table, and bind it to seperate controls row by row, should i use a SQLDataReader or load the data into a dataset, or run a stored procedure to pull the data?
Which is the best way to get data from sql and bind it to controls in this situation?
For example:
label1.text = sqlcolumn1.row1.value;
label2.text = sqlcolum1.row2.value;
Etc...

I have a big form in which i have almost 10 update panels. some are having updatemode = conditional and others are always. Now by default when that page is opened i only show one dropdownlist.When that project dropdownlist (from which i populate the rest of the elements in my page) value is changed by user it takes long time to load the other elements. Also the other gridview which is also surrounded by update panel and mode in conditional takes long time to show edititemtemplate controls in edit mode.
I am unable to trace the reason behing delay. Few days ago it was working fine and fast but now it is slow.

I have several rows in my database like this
ID Status Type Count Event
291 0 0 2 1
523 1 2 0 4
and so on. When my user performs some basic actions on my website, some values are passed through JSON to the server and are then converted into custom objects with 5 int properties(so they match the table). These objects that the server receives are the rows to be updated(based on ID) and the values for each column. How can I do this in one SQL statement without the need to loop through each object and update them all seperately? Is there a way? Preferably compatible with SQLServer 2005.

I'm trying to figure out how to update multiple rows in my Directory table, when a user changes their Street Number or Street Name in their profile. They can add multiple users to a directory and each user they add to the directory has this primary users UserId in it. So if the primary user changes their address, I want it to update the address for all the users they listed in the directory as well. I'm adding this to the On_Click in the Code Behind, so when they click to update their profile, it fires this function as well. This code may be way off, but here's what I have right now:

I wrote in subject "Is there any way to UPDATE multiple rows WHERE UserID = @UserID_ArrayList" For example I have an Arraylist like this:
Dim UserID_ArrayList As New ArrayList
UserID_ArrayList.add("100")
UserID_ArrayList.add("150"
UserID_ArrayList.add("200")
Now I have to UPDATE some columns inside those 3 records WHERE UserID = @UserID_ArrayList I'm sure it can be done somehow?

I want to add multiple rows of a gridview if the data for multiple fields are same.Idea for this is that a user may search a record with some parameter e.g. Sector, plot.For example 15 records being displayed in gridview.There should be checkbox before every row and if user wants to update Plot and Flat No that is same for 10 rows out of 15 so he will check the rows and update.For this a dialog box should appear asking for the parameter i.e. Plot and Flat or something else next time may be it will be City or country. Moreover, there is already an Edit button to update records, when user click it another page open for the record to be updated and whatever he wants to update, it updates.

I need to produce a from where I can add multiple parts. Each time a user enters a part number, the description should be populated. The user can then click add and this part and description will be shown below. They have the option to add as many parts as they require. Once all parts are added the user fills in some general info eg description and then once a submit button is clicked all part info will be inserted into a table and general info will be inserted into another table with one unique ID.

Our problem is the following:
We have a website that processing products from various web shops! Users of these web shops can send products for our site what will store these products in our database. Users are sending in products through the post method of the form, and within the form the data is in hidden imput fields! Our site using UTF-8 charset, and this service is working like a charm together with other pages that has utf8 chaset too. The problem comes when someone using our service from a site that has other charset then utf8, for example: iso-8859-2.This case the special hungarian characters, like "íéáűőúöüó" are replaced with a '�' character!We have tried to convert the incoming string on server side but that case the '�' has been replaced by '?'. - still not acceptable :)

Using Facebox with .NET (Web Forms) is painful--this primarily HTML site was designed by someone else. I may have IIS (7.5) issues as well. This Facebox pop-up is in a separate file, login.html, that is called from index.html:
$k('a[rel*=example_2]').facebox_1({
loading_image : '/images/loading.gif',
close_image : '/images/closelabel.gif'
});
and the link to open it
<a href="login.html" title="Log In" rel="example_2" id='login'>Log In </a>
The form to be submitted with username and password (login.html):
<form name="login" method="post" action="#" onsubmit="return false;">
and after it's validated (this is working), it posts to login.aspx (login.html):
[code]....
The form posts. I can debug it in Visual Studio in the Page_Load method of login.aspx. The last line of the Page_Load method is:
Response.Redirect("welcomepage.html");
But, the Facebox pop-up remains. Firebug shows the post, It hits the Page_Load method of login.aspx, and the Facebox pop-up doesn't go anywhere. BUT, Firebug shows welcomepage.html rendered twice in the Response tab of the XHR (huh? why XHR?) request. I thought $.post did a regular postback. And why isn't my browser actually redirecting.
Attempted Fix
If I change the form in login.html to action='login.aspx', I get a 405.0 error method not allowed (but, it's trying to post to index.html, HUH?). And I can't figure out how to fix this in IIS 7.5 on Windows 7. I get this error in Visual Studio and when deploying locally to IIS. I had read it may have to do with script mapping, handlers, or the fact that I'm posting from an but I can't find a sufficient fix.
