MVC :: ViewPage Makes ViewData Disappear?
Aug 6, 2010
I'm trying to do:
[Code]....
But each time I do this, the ViewData object seems to disappear (intellisense doesn't show it). Also, Model goes away too. I must be making a really simple/dumb mistake. I also tried to Import the namespace containing the CompanyModel class on the same aspx, but that doesn't do anything.
When I try to view the page in the browser I get this error:
Parser Error Message: Could not load type 'System.Web.Mvc.ViewPage<CompanyModel>'.

I have masterpage which includes dropdown list for choosing skins for page.
Also I have Home.aspx include above master page. This Home.aspx contains update panel[up1] which further comprises of gridview, link button, image button[IB] and dropdown list. Also there is one modal popup that has a panel which includes dropdown and text box.
Requirement: when i click image button[IB], modal popup opens up and home.aspx gets grayed up.
Issue: when i click image button[IB], modal popup opens up, but all dropdowns placed in[Home.aspx and Master page] get disappeared[invisible]. Once i close modal popup , they are visible.

Basically, I have a gridview and it has RowEditing function, which to be fair has two lines of code
GridView1.EditIndex = e.NewEditIndex;
GridView1.DataBind();
When I press the edit button from one of the row in gridview, it hides the whole gridview!
To bring it back, I have to call the function which does the binding and suprisingly, it loads back in edit mode!

System.Web.Mvc.HtmlHelper<object>' does not contain a definition for 'GridView' and the best extension method overload 'MvcApplication2.Code.GridViewExtensions.GridView<T>(System.Web.Mvc.HtmlHelper, MvcApplication2.Code.GridViewData<T>, System.Action<MvcApplication2.Code.GridViewData<T>>, System.Action<T,string>, string, string, System.Action<T>, System.Action<MvcApplication2.Code.GridViewData<T>>)'

I am a longtime .NET developer but for big applications and services. This is my first asp.net project and I have chosen MVC. I have a need for nesting a ListView within a ListView. In this simple catalog app, I have EF 4 Entities that are Categories, SubCategories, ItemTypes, and Items.
My goal is to display a 5 column layout of SubCategories with their ItemTypes below them in a ViewPage. I did just fine with it done out in C# as server directives such as:
[Code]....
But now I would like to do it with nested listviews and I am having trouble with binding in the inner listview. Here is what I have so far:
[Code]....
The bolded line is bogus, of course. The listview won't accept a declarative datasource in this situation. How do I bind to the ItemTypes of the outer SubCategory?Also, I understand there is no code-behind file and I accept that this is because all logic should be in the controller. But does that leave me with the inline binding shown above for the outer listview?
<%
SubcatList.DataSource = Model.SubCategory;
SubcatList.DataBind();
%>
Or is there a more elegant way that doesn't involve an inline server directive?

I am developing a website which will be having both asp.net pages and MVC pages in it, So I have BaseWebPage class which will be used for both asp.net pages and MVC Views. but My BaseWebPage class is inherited from System.Web.Mvc.ViewPage, So Will there be any code/ functionality break for normal asp.net pages, because System.Web.Mvc.ViewPage is overriding some of the Pagelife cycle methods.

Inherits="System.Web.Mvc.ViewPage<Domain.Enquiry>"
My controller has two actions as follows:

I can have a base class for views in an MVC project like this:
public class BaseViewPage : System.Web.Mvc.ViewPage
{
public string Something { get; set; }
}
And then in the ASPX I can do this:
<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage" %>
This works fine; the problem is when I try to do the same with the generic version:
public class BaseViewPage<TModel> : System.Web.Mvc.ViewPage<TModel> where TModel : class
{
public string Something { get; set; }
}
When I try to use this from the ASPX, like this:
<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage<SomeClass>" %>
I get the error message:
Error parsing attribute 'something': Type 'System.Web.Mvc.ViewPage' does not have a public property named 'something'.
Notice how it tries to use System.Web.Mvc.ViewPage rather than my BaseViewPage class. To make it more interesting, if I remove the "Something" attribute from the Page directive and put some code in the generic version of BaseViewPage (OnInit for example) the class is actually called / used / instantiated.
So, am I doing something wrong or is this a limitation.

I use Visual Web Developer 2008 Express. I am following a tutorial which uses VWD2005 and says to create an Ajax enabled website. There is no specifically named "Ajax enabled template" in VWD 2008 Express
I think I have created one by creating a new ASP.NET website and adding a ScriptManager and an UpdatePanel to the page and placing the content of the page inside the UpdatePanel ContentTemplate.
I am trying to rule out reasons why my aplication wont work - step by step, piece by piece, from the beginning of the tutorial.

In my asp.net application on Windows Server 2008, I have code like this
tempfile = Path.GetTempFileName()
... Write data to tempfile ...
File.Move(tempfile, storageDir + fileName)
This works just fine. The problem is afterwards when I am trying to access the file from outside of ASP.NET. I get access denied, even though the user I am accessing from have (recursive) read rights to the storageDir folder.
It seems that the moved file doesn't inherit rights from the folder it is moved into. Is this correct, and if so, is there an easy way to fix that?
Right now as a direct fix I have changed every instance of File.Move() in my ASP.NET application to File.Copy() + File.Delete(), which seems to fix the problem.

In the code below, I learned to use a trigger to either display or hide a panel (pnlMaidenName_Edit) when the user clicks on either side of a radio button (rblGender_Edit). The problem now, however, is that whenever rblGender_Edit is assigned a SelectedValue of 2 for female, the hidden textbox displays in a location way out of position from where it should be. Also, the radio list button displays again, as shown in the following screenshot, near where the textbox now displays.

I am working on a ASP.NET application that uses ASP.NET MVC.I tried naming one of my controllers "AdminController" meaning I typed "Admin" in the new controller text box and it filled out the controller part all by itself of course.This controller never worked until I changed it's name. If I changed the name to anything else it worked with no problems.I looked inside my Global.asax.cs file where the routes were configured and I found no routes leading to it.I tryed adding a route to this new controller like this:
routes.MapRoute("Admin", "calcul/SomeAction",
new { controller = "Admin", action = "SomeAction" });
and it worked but then mysiteadmin would only get routed to that specific action.I renamed the controller to AdminSection and it works but I don't understand why it didn't work before.

I thought you might want to know this, the beta of IIS Express will be released soon, and will make use of the best of both worlds: VS build in web server and IIS in Windows itself. Anyways, IIS Express makes it even easier to build, run and test web applications.

We are migrating a project from classic Asp.Net web forms to Asp.Net MVC. I have followed the fours steps outlined here [URL] and all is working well. Now I want to get Visual Studio to include MVC item templates in the "add new item" dialog. So I add {F85E285D-A4E0-4152-9332-AB1D724D3325}; to the <projecttypeguids> element in the csproj file. So this succeeds in adding MVC support to the Visual Studio "add new item" dialog, but now the build fails. And it fails in the strangest way. The three projects that make up the solution each complete with "build succeeded" but the process ends with a message
Build: 2 succeeded or up-to-date, 1 failed, 0 skipped
I am able to F5 debug, but I am not able to publish. We are using Visual Studio 2008 SP1 and migrating to MVC 2.0. Anyone have any ideas why the build is failing after adding this project type guid?

I'm fairly inexperienced with JavaScript and jQuery,but I need both for the ASP.Net website I'm working on. I am slowly figuring it out, but I've been relying heavily on StackOverFlow.Does anyone know of any tool (preferably free) that makes debugging JavaScript and jQuery easier?I've been using Firebug which has been helpful,but I guess I'm just spoiled by Visual Studio's debugger and intellisense.Is there anything like that for JavaScript and jQuery?It would sure make my life easier if there were?

I have two pages, step0 and step1.
Users get firsly to the step0 page, where they fill some info, the page updates, they fill some more, and then get redirected to step1 page.
Problem is that upon getting to the Step1 page, if the user clicks on the back button, then he gets to the last stage of the step0 page, which uses sessions and variables that are no longer existing, what causes a crash.
I'm looking for an elegant way to make sure that with each page visit, the page will restart itself to start phase.
I have this idea maybe twitching the Page_Load function, something about the is_post method, but since each page's post back hits this function,
