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.
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?
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.
I 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?
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.
My page (which basically contains a pair of Repeaters) renders and is displayed to the user.I'd like to have a "Download" button on the page which, when clicked, will propmt the user to save the page locally as an html file without losing any of the CSS formatting.
My CSS files are linked to via a Master Page.Currently, I have the button linked to some javascript that open will the Save As dialog, but all of the CSS formatting is lost, and it saves the page .I'm assuming that the button will need to open a new page which will re-create the data for the Repeaters and then save using StreamWriter, but I'm not exactly sure if that's right or how best to do it.
one button i use to save form entity.and other is to navigate to next pagwhen i click on save button i use jquery to save form entity in database. and form remains as it is
i have place some .txt files in my web application root directory. now i want to open a popup on button click with save button so that client can save this file on his/her PC. also can we auto set the path??? mean client jst press save button and file automatically stored his "D:\Foldersample.txt".
I have one AsyncFileUpload control ,one Attach button,one Listbox and Save button.
When Users browse the file and click the attach button, filename must be added to listbox. So in this way the user has the option to add upto multiple filenames to listbox. For this i have written the following code
[Code]....
this is source code
[Code]....
In Attach button click event i added the filename to listbox and saved the Asyncfileupload controls in different session variable.
When user clicks on save button all files has to be saved in application folder and for this i wrote the following code.
[Code]....
But iam unable to save all the files . Suppose i added two AsyncFileupload controls to session variables, only last file i,e. 2nd file can only be saved and couldn't get first file.
fileName is the name of the file ending with the file extension (.pgn). However, the file is saved as a .txt file, ignoring the extension that I am giving it. Would this have to do with the Response.Contenttype = "text/plain"? How can I get the Open/Save dialog to display and save the correct (.pgn) filename?
Also, if filename is a string separated by dashes or spaces, when the Open/Save dialog comes up, the filename is not displayed in its entirety but it is truncated where the first dash (-) or space (or comma) is encountered. How can this be remedied?
I am creating the user ,using asp.net + C#.there is the form (UI) who collects the information and send data to Business layer. now, while collecting the information from UI I want to also save the image of user, at file system in application domain.There is function in the business layer as SaveImage, which returns the path where it is saving. Scenario:1) Save image first and then save other information in DB.
I am getting the above error when I am trying to save a value '<TS1'. I did the search and came to know it is about html injection. So I entered ValidateRequest="false" on top of the page and in the code behind file I have the following code.
Protected Sub fvAddCompass_ItemInserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewInsertEventArgs) Handles fvAddCompass.ItemInserting Dim strProvided As String strProvided = HttpUtility.HtmlEncode(CType(fvAddCompass.FindControl("ddlAddProv"), DropDownList).Text)
My problem is now it is not giving me the error, but entering a blank value when I am trying to enter '<TS1'. By the way, it is not giving me any problem if I tried to enter >TS1 as a value.
