MVC :: Checking Which Values Have Been Edited In A FormCollection?
Aug 13, 2010
I want to know which fields were edited in a form in the Edit Action. I have a Log field in a table named "someTable" which I wish to add the change to, along with the Username of the current user. This is a simple implementation:
[Code]....
Can someone tell me where I am going wrong, because the getChangedAttributes function always returns an empty list (assuming because "backupTable" and "form" contain the same values? But shouldn't they be different?

My application writes custom attributes to input controls using Helper classes. And also we are loading the UserControl dynamically so we need to use FormCollection to get the posted values. Is there a way that we can access attribute values from FormCollection object.
Example:
<input type="text" name="textBox1" value="harsha" customAttr1 = "MyValue" />
My question is how can i access the value of customAttr1 from the above eg from inside the controller.

I am binding the ReorderList in my code behind file. I am not using a DataSource Control like SQLDataSource etc. How will I capture the values edited, in my ReorderList1_UpdateCommand(). In GridView we can use something like
(TextBox)GridView1.Rows[e.RowIndex].Cells[4].FindControl("txtMyTextBox").Text. Is there anything similar in a ReorderList?

I have a standard gridview, populated via a SQLDataSource, with columns converted to templates.
The edit templates have text boxes. When saving edited data via these text boxes, I need to trim the values to remove any spaces.
How do you recommend doing so? I've tried various methods but none seem to work.
Currently my update parameters are specified in the SQLDataSource.

using the latest bits for MVC 3 i'm looking at the code for a Controller (Northwind products), specifically my 'Edit'Action.
there are two methods, one for diplaying the item to edit, and one for posting back changes made on the UI.
My question is : how do i get a reference to the currently edited product. The method takes 2 arguments; the id of the product and a formcollection which is a dictionarly of product proerties by the looks of it. mvc 2 had slightly differentt arguments compared to mvc 3 beta.

I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.
I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set
to an instance of an object" error when I click the Update link for the row of data being edited.
At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).
For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).

protected void rptNavigation_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e){
if (!((e.Item.ItemType == ListItemType.AlternatingItem) || (e.Item.ItemType == ListItemType.Item)))
{return;
}string Name = string.Empty;
if (IsDBNull(e.Item.DataItem["FullName"])) {
Name = String.Empty;}
else {Name = (string)(e.Item.DataItem["FullName"]);}
Literal ltlLiteral = (Literal)(e.Item.FindControl("ltlLiteral"));
ltlLiteral.Text = Name.ToString();
I get error for IsDbNull - Error 1 The name 'IsDBNull' does not exist in the current context. What's the best way to check for null values returned from db? also I get errors on both lines where (e.Item.FindControl(ltlLiteral")); is present ERror: Cannot apply indexing with [] to an expression of type 'object'

I'm using C# and SQL Server. I have one gridview which contain 3 columns "ID, COMPLETED (either yes or no), BY (adminID that completed)" and adminID can be null.
If user selected "yes" in COMPLETED column then how can I make sure that adminID in BY column is NOT empty or adminID entered is EXIST in database.

I have a .net 3.5 application in c# with sql server 2008 at back end. The application is about assigning jobs to supervisors and then these supervisors have to write remarks about the job progress from time to time. There are two tables ; a JobAssign table with JobOrderNo and Supervisor columns, and a JobUpdate table with jobOrderNo,Date And Remarks(nvarchar) column.
When a supervisor is assinged a job he is sent an email but sometimes the supervisors do not write remarks about a job for some time. i want a stored procedure through which if the remarks of a job are not written for say 5 days an email is sent to the supervisor to do so? in my job update table there are multiple entries for a job so the stored procedure will have to check the Top Remarks Date for each jobOrderNo. then compare it to today date if the difference is difference is 5 days then send email. i have read posts on sending email through job scheduler but i'm new to stored procedure so have no idea how to write such.

Ive got a scenario where a form is filled in and the action picks it up as a FormCollection. It then carries out validation on it and if it fails sends it back to the form again, however i cant seem to get it to re-populate the form.
If i do something like:
[Code]....
So it just looks for name in whatever is passed over... ideally i dont want to involve a model unless it has all validated fine, but if there is no other way around it can populate a model and do the validation on the model instead...

FYI I am using .NET 4.0 / MVC 3. In my controller, the following is my code:
[HttpPost]
[ValidateInput(false)]
public ViewResult Edit(ContentTemplateView contentTemplateView, FormCollection collection)
Everything works fine when I don't enter HTML, so I know the proper controller is being fired. Also, I have following set properly in my web.config files:
<httpRuntime requestValidationMode="2.0"/>
I only get this problem when I include the FormCollection (which is needed for this particular Controller). So what exactly am I doing wrong? [I have done what was proposed on the following questions, and they work as long as there is no FormCollection. None of them offer a solution with an included FormCollection] Why is ValidateInput(False) not working? Asp.Net MVC Input Validation still firing after being disabled ValidateInput Attribute Doesn't Seem To Work in ASP.NET MVC

I'm overriding the OnActionExecuting method in a base Controller. When a form gets posted - anywhere, I want to check for a certain form element in this method. In any Controller method I can just include the FormCollection as one of the params in its signature, but if I try that with the OnActionExecuting method I get an error saying that there's no suitable method to override. How can I get past this?

I am just wondering how you'd iterate through elements in a form input array when you get the FormCollection object on postback?

I have a strongly typed view for my User edit action. When I press edit all the fields in Users model is filled with values from the DB. If I enter an invalid data for a particular field say email, then the view throws an error, but after that the email field contains data pulled from the DB and not the one which i entered previously.
I will explain to you in steps if my explanation is confusing.
1.Click the edit action.
2.A page displays with all fields in my User model.
3.Email field contains : johnson@company.com (pulled from the database)
4.I try to change the email to "johnson@company1" (This is an invalid email id)
5.The form does a post back and return an error saying that email id is invalid.
6.Email field contains : johnson@company.com (pulled from the database) and not "johnson@company1"
Is there a way to convert the FormCollection to an User model and send it back to the view?

In my ASP.NET MVC app I am rendering out a checkbox using the following code:
<%= Html.CheckBoxFor(i=>i.ReceiveRSVPNotifications) %>
Now I see that this renders both the checkbox input tag and a hidden input tag. The problem that I am having is when I try retrieve the value from the checkbox using the FormCollection:
FormValues["ReceiveRSVPNotifications"]
I get the value "true,false". When looking at the rendered out HTML I can see the following:
<input id="ReceiveRSVPNotifications" name="ReceiveRSVPNotifications" value="true" type="checkbox">
<input name="ReceiveRSVPNotifications" value="false" type="hidden">
So the FormValues collection seems to join these two values since they have the same name.

I am currently developing an application with the new ASP.NET MVC2 framework. Originally I started writing this application in the ASP.NET MVC1 and I'm basically just updating it to MVC2.My problem here is, that I don't really get the concept of the FormCollection object vs. the old Typed object. This is my current code:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(FormCollection collection)
{[code]....
What are the benefits of switching to FormCollection in MVC2 and more importantly - how is it used properly?
