Forms Data Controls :: Value Of Control Is Empty After Submitting The Form 2nd Time?
Mar 10, 2011
I am experiencing a problem on my aspx page.
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.
Here are some bit of codes
protected void Page_Load(object sender, EventArgs e)
{
foreach (int assetclassVal in Enum.GetValues(typeof(AssetClass)))
{
[Code]....
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.

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 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'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.
searchType = "books"
searchEngine = "library catalog"
keywords = "some keywords"
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:
[URL]
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 do some stuff with dynamic DropDownLists. A choice at one level makes the next level appear and so on.
When I open up an old report for editing, the first level is not editable so I set that DropDownList to Enabled=false (still dynamically in code).
My problem is that when I press save (a LinkButton) I first come to my OnInit as usual and check the Page.Request.Form for my DropDownLists, but then the first list is not represented.
But if I change one of the lists when editing, a postback is made, then there is no problem at all with the Page.Request.Form, the first list is there all the time.
Is there some fundamental difference with causing a PostBack from a LinkButton vs a Dynamically Added DropDownList?

I am trying to use link to submit a form using the following code:
function deleteItem(formId) {
// submit the form
$("#" + formId).submit();
}
Basically I have a grid and it displays a number of items. Each row has a delete button which deletes the item. I then fire the following function to remove the item from the grid.
function onItemDeleted(name) {
$("#" + name).remove();
}
It works fine when I use a submit button but when I use action link the JavaScript from the controller action is returned as string and not executed.
public JavaScriptResult DeleteItem(string name)
{
var isAjaxRequest = Request.IsAjaxRequest();
_stockService.Delete(name);
var script = String.Format("onItemDeleted('{0}')", name);
return JavaScript(script);
}
And here is the HTML 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.
<div id="login">
<form action="index.aspx" method="post" id="nothingForm" name="nothingForm">
</form>[ code]....
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 using the latest RC with asp.net mvc 3, and have turned on unobtrusive javascript validation and added the necessary scripts to the page. All of the validation works perfectly, but when I try to submit the page, it simply doesn't post. If I turn unobtrusive javascript off in the web.config without making any other changes, everything works perfectly fine.
Here's my scripts I'm using:
<script src="@Url.Content("~/Scripts/jquery-1.4.4.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>

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 am trying to create a java script function to keep track of the changes made in a web form while submitting the page. For normal .net textbox or textarea I can compare the value with default value.
var ele = document.forms[0].elements;
for ( i=0; i < ele.length; i++ )
{
if ( ele[i].value != ele[i].defaultValue ) return true;
}
But the problem is, I have a dnn texteditor in my web page. And ele[i].value does not change if user change the text in the texteditor. It always returns false as it could not track the changes.
Is there any attributes of the dnn texteditor control that holds the changes data?
