I am working with MVC2 and one of the view model's properties is IDictionary<Int32, String>.
This is not to be changed on the view. But when the form is posted back I would like to still get those values.
Can Html.Hidden store this property values?
How should I do this so the model still gets the IDictionary<Int32, String> values on the POST action?
I am having a problem where when I form post to an action it gets null values in my hosted enviroment although if I use a model to bind to it works fine. Everything posts and works correctly when I run the project.
So far I have tried to pass the form fields back as parameters on the action and get the value through the context request. Both work fine but as soon as I publish it to the hosted enviroment, it doesn't work. in the view I have:
<%=Html.TextBox("subject") %>
<%=Html.TextBox("comment") %>
for the action Method:
[HttpPost]
[Authorize]
public ActionResult Reply(int? id, string subject, string comment)
{
//Some code...
}
I have verified that it is hitting the action but the subject and comment values are null. I am guessing I am missing something simple, maybe a security setting in the config, that is causing this since I am still fairly new with MVC. I am running VS 2008 with MVC2.
I am not able to assign the values or get the values from IDictionary<string, IParameter>.

I'm trying to add file upload functionality to a page. I've got a form that posts the selected file to a controller with a 'savefile' method. But if I don't add a get version of 'savefile' I'll get a 404 error. Here is the form code which is presented on the Index page:
[Code]....
And here is the controller code:
[Code]....
Intuitively I don't think I should need a GET version of SaveFile but if omit it I get a 404 error when the form posts. Why should I need a GET version of SaveFile when all I want is to post a form and save the file?
I'm using a GridView control to edit data in a MySQL database.
I've created the C# code behind but I'm having trouble pulling back the parameter from a radiobutton control to populate an Int32 field in the database. I'm getting "Input string not in correct format"This is the particular bit (amongst a host of others of the same type) that is causing the problem:
cmd.Parameters.Add("?yes", OdbcType.Int).Value = (Convert.ToInt32(((RadioButton)GridView2.Rows[i].FindControl("edYes")).Text));
I am not sure where my app is failing but most probably this is where it is failing.. I think lblExpID.Text is the culprit. Here's the relvant part of my code:
Dim lblExpID As Label
For Each item In LSGrid.Rows
lblExpID = item.FindControl("lblID")
If txtExpGenFund.Text <> "" Then
sqlArray(i) = ExpDetailsID & "," & (lblExpID.Text) & "," & MunID & "," & _
Val(txtExpGenFund.Text) & "," & Val(txtExpDetSpecialRevenue.Text) & "," & _
Val(txtExpDetCapitalProjects.Text) & "," & expTotal & "," & reportingYear & "," & "Test Comments" & "," & UserID
End If
Can u help me identify why i am getting this error looking at the sp below:

I swear I'm overthinking this as I've tried different combinations to do an insert from Code Behind to my Sql DB.
This is what my table looks like:

My code behind:

I suspect that the problem may be my date. The format that goes from the UI is mm/dd/yyyy.
I got this error message when I use rowfilter
Line: 938 Error: Sys.WebForms.PageRequestManagerServerErrorException: Cannot perform '=' operation on System.Int32 and System.String.
My code is like this

When I check only string, it's okay
But I have to check string and int because some columns are only Integer such as LLMS_Id, Risk, RsidualRisk
Sometimes Convert.ToInt32(object) will work and other times (Int32)object will work. How do you know which to use? I usually try one and if it doesn't work use the other but I'm sure that's not the best approach.

i wonder something about mvc post method. for example I created a view "strongly typed" from a model (MyModel).
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Demo1.Models.MyModel>" %>
for Create actionsthere is two way.
first one takes MyModel as parameter
[HttpPost]
public ActionResult cart(MyModel md, int someID)
{
//some code
//.....
return View(MyModel);
}
second one does not take parameter as model.
[HttpPost]
public ActionResult cart(int someID)
{
//some code
//.....
return View(Mymodel);
}
for first one way, after form post the form values does not delete, I mean form does not cleared,after second one form is be cleared. why this diffirence?

company.Id has a value of 10, but company.User.Id is 0. what I'm doing wrong? I've not named any properties incorrectly, by the way.
I must miss something obvious here when using htmlbegin form. I noticed that it takes (or tries to take me) right to the view rather than the an action. If I replace SearchAction with SearchResult is goes nicely to the view, not considering the action.
Using SeachAction leads to the error that it cant find the view.
I have an ActionResult that accepts POST, however is there a work around for me to redirect from a controller to another controller containing this POST method/action?

View 1 Repliespublic class BandProfileModel
{
public BandModel Band { get; set; }
public IEnumerable<Relationship> Requests { get; set; }
}
and the following form:
<% using (Html.BeginForm()) { %>
<%: Html.EditorFor(m => m.Band) %>
<input type="submit" value="Save Band" />
<% } %>
which posts to the following action:
public ActionResult EditPost(BandProfileModel m, string band)
{
// stuff is done here, but m is null?
return View(m);
}
Basically, I only have one property on my model that is used in the form. The other property in BandProfleModel is just used in the UI for other data. I'm trying to update just the Band property, but for each post, the argument "m" is always null (specifically, the .Band property is null). It's posting just fine to the action, so it isn't a problem with my route. Just the data is null.
The ID and name attributes of the fields are BAND_whatever and Band.whatever (whatever being a property of Band), so it seems like it would work. What am I doing wrong? How can I use just one property as part of a form, post back, and have values populated via the model binder for my BandProfileModel property in the action?
i am thinking to capture which button has caused a postback in the web pages.
Is it possible to do so?
i am making a forum application using MVC 2. I have a ForumController which has Index and Create Actions. The Get Create Action returns View and the Post Create Action takes an argument of type "ForumEntry". When i generate create view i make sure that i check "create strongly typed view" and i select models.ForumEntry Model and NOT the models.Forum Model. The Forum model is ADO.NET enitity model that maps to Forum Table. I want to catch ForumEntry type into my Create Post action but mysteriously i get a Forum Object. I have verified this by returning Content When :
[HttpPost]
Public ActionResult Create(ForumEntry entryToCreate)
{
return Content (entryToCreate.Title); // No Output
}
When
[HttpPost]
Public ActionResult Create(Forum entryToCreate)
{
return Content (entryToCreate.Title); // output == new entry that i typed in the create form
}
I am baffled as the create Form is of type FormEntry. Here is the code for create View
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Aspforum.Models.ForumEntry>" %>

I'm attempting to write a unit tests for an ASP.NET MVC 2 post action that takes a view model as its sole parameter. The view model is decorated with validation attributes such as [Required]. I'd like to test two scenarios. The first scenario is when a valid set of data is passed in (ie, all required properties have values) and a redirect to the list page is returned. The second scenario involves passing in invalid data (eg, when one or more of the Required properties are not set). In this case the same view is returned with error messages.The action signature is as follows:
[HttpPost]
public virtual ActionResult Create(NewsViewModel model)
The NewsViewModel class is as follows:
public class NewsViewModel
{
public Guid Id { get; set; }
