I have a form that contains a number of user controls (partial views, as in System.Web.Mvc.ViewUserControl), each with their own view models, and some of those user controls have nested user controls within them. I intended to reuse these user controls so I built up the form using a hierarchy in this way and pass the form a parent view model that contains all the user controls' view models within it.For example:
Parent Page (with form and ParentViewModel)
-->ChildControl1 (uses ViewModel1 which is passed from ParentViewModel.ViewModel1 property)
-->ChildControl2 (uses ViewModel2 which is passed from ParentViewModel.ViewModel2 property)
-->ChildControl3 (uses ViewModel3 which is passed from ViewModel2.ViewModel3 property)
My question is how do I retrieve the view data when the form is submitted? It seems the view data cannot bind to the ParentViewModel:public string Save(ParentViewModel viewData)...
as viewData.ViewModel1 and viewData.ViewModel2 are always null. Is there a way I can perform a custom binding?
Ultimately I need the form to be able to cope with a dynamic number of user controls and perform an asynchronous submission without postback. I'll cross those bridges when I come to them but I mention it now so any answer won't preclude this functionality.
i want to build a user registration page where a user can submit his firtname,lastname contact address telephone,email and upload a passport size picture with a specific file size and if bigger than the said image size it will not upload to the database and to be able to retrive back all information submited with the form including the passport size photograph and view them in a given page. I have been trying my hands on it but i could not get it work.
I have a simple form written in asp.net/C# and when trying to hit enter while in the form's input box doesn't submit the form for some reason. I had implemented a fix for a previous bug where pressing enter would merely refresh the page without submitting the form data but now pressing enter just does nothing, the fix is below:
I have a web form on which the user fills in a basic data: date (with drop down lists), an asset class (with a radioButtonList that is bound with en Enum) and other simple controls... The, when the form is submitted, I make a query on the database to retrieve my data and bind these data into a gridView.
The 1st time I submit the form everything is working well, the second time even if I change nothing in in the web form, the GridView1_RowCreated fires an exception when the property AssetClass is called. The error message is
Must specify valid information for parsing in the string.
﻿This is because rblAssetClass.SelectedValue is empty, but I don't understand why.
My website has a "charts" menu item that lets you choose from about a dozen pages each with a different chart in them. Each one of these pages uses the same nested master page which has some drop-down lists and text boxes to let the visitor do some filtering of what data shows up in the charts (I do this by building SQL statement parts in the nested master page and triggering an event that the chart page reacts to).
Anyway, One of the DropDownList controls shows the names of everyone in the Company (I use MembershipProvider and RoleProvider). What I want to is have the DropDownList show a different collection depending on the role that the visitor is in; If the visitor is in the "Principal" role, I want them to see everyone. If they are not in that role, I want them to get only their own name.
I expect I'd have to do this in code-behind... But thought I'd check to see if anyone knows if it is possible to have an "IF" statement in the SQL DataSource for this control that can refer to the role that the current logged-in user belongs to
I have a site master page which has 2 forms on it like so
But when I click the submit button in the second form on the page it submits the values from the first form to my controller and will run both controller actions. What I want is each form to submit only its own data is there some special way to do this?
OK, I have exhausted myself troubleshooting this bug. The crazy thing is, I think I had it working months ago, and now it does not. All I want to do is submit FrmCart when the "Update Total" link is clicked. Below is the code.
My website has been created with a CSS/HTML frame work that has been integrated into an ASP.NET website. Inside of a ContentPlaceHolder, I have a simple login form. The catch is that I am using the onclick event of an image to submit the form. It normally works pretty straight forward, but this time I am having an issue.
I have to stick another form before the real form to make onclick="document['loginform'].submit()" actually work. This should not be the case, of course, but I was unable to find any solutions to it on the web.
I'm not sure the best place to ask this...not even sure the best way to ask it.
I manage a library website, and there are a number of different database products that can be searched. I'm trying to build a black box application to sit behind the home page. Here's an example of what might get submitted to said application.
See, the idea is that I might be doing various search boxes throughout the site, and I want to keep the actual HTML forms as simple as possible and simply let an ASP.Net application do the rest of the work. For example, figuring out whether or not the search engine using a GET or a POST method, parsing the keywords to determine the best way to render them, and sending the appropriate hidden values.
Probably, most of these databases use GET, so I can simply use a Response.Redirect after creating the query string, but I think some of them might use a POST, and I'm just not certain how I would take the form variables from one page (the home page, say), then essentially turn them into a virtual form on this middle man/black box application, and then programmatically submit that virtual form to another site, such that the user never sees or knows about that intermediate page.
I've seen this:
But that isn't what I actually want to do, because I don't want to retrieve the result of the submission through a WebResponse...rather, I want the form to actually send the user to the new site.
I'm quite confused about how to implement a many-to-many relationship and my domain model. Let's say I'm creating a recipe box web application and I have three tables called Category (categoryID, categoryName), RecipeCategory (categoryID, recipeID), and Recipes (recipeID, recipeName, recipeDescription). If I were to present this information as an ASP.NET application and wanted to insert a new recipe and category, am I responsible for writing the logic to insert the information in the RecipeCategory table OR is it possible to set RecipeCategory.categoryID and RecipeCategory.recipeID automatically with default values based on newly inserted records in the related tables? If I'm responsible for writing the logic to insert values in RecipeCategory.categoryID and RecipeCategory.recipeID is that a trigger? What's the best way of implementing this?
I have used Expression Web to create a website with a standard .ASP form that saves data into an Access database using standard HTML controls. This works fine except there is no validation of the fields. A user can enter anything to get past the form.
I want to use ASP.NET to validate all of the fields in the form and then save to the same Access database. When I rename the webpage from .ASP to .ASPX, I am able to get the validation controls working properly by changing HTML controls to ASP.NET controls.
However, I cannot figure out how to get the form data submitted into the Access database because the code to connect to the database was removed when I inserted the first ASP.NET control.
What am I missing? It seems like a simple task but I haven't been able to figure it out. I have a couple books and they don't answer the question. Can someone guide me in the right direction?
I'm trying to do a form submit to my controller through jQuery Ajax. The following code works for the most part, however, the ThreadId parameter does not get passed. If I call the controller directly without using jQuery, it gets passed, but when using jquery, I don't see the ThreadId after form.serialize(). WHat would be the easiest way to pass parameters (like ThreadId) to jQuery form post?
I have a button that does a postback to server then back to client and finally to the action attribute of the form element.When the page post back to the client the onload <script>document.frm.submit()</script> finally submits the form to the action attribute of the form.I would like to eliminate the unnessasay post back to the client.Below is the code the runs on the server.
I was wondering if there is an easy way to submit a form or a collection of fields with jquery and json to a C# server-side script. I was thinking of a script that retrieves all data from elements with an attribute called 'form' (yes, we just add a new attribute to for example a textbox or textarea). Thus, the script searches for all form attributes with form='myform' and then submits the data as an form object. In server-side code we know how to deal with the data. Does someone has such a script? Or can I inspire someone to develop such a script? (I have the idea, not the skills) ..also, sessionstate needs to be available (cookie).
Im dynamically creating several dropdowns onclick of a button... but the dropdown returns null when im trying to get the values on submitting the form... i read tat during postback all dynamically created controls will be lost... s there a way to register the controls... i want to access the item selected in the dropdown .... expecting a positive reply...
I have a Web User Control I created for authentication. The web user control is inside the box below. Clicking any button (1 or 2) below works correct as it goes to the correct c# button click event in the code behind file. If I press enter on fields a or b it goes to the correct callback (button1's) if I press enter on field c it still goes to button1's callback, not button2's
How can I give my web user control a nice self contained for and view state etc, so it wont mess with the remainder of the page's form?
