now i want to click the link in partial view and show it in master page. how to do this?
sorry for my bad english.
hope u guys understand..
Best Regards,

If I understood your question correctly ,you organized the partial views and your master page in a wrong way and you expect something wrong.
You should create a MasterPager (or _Layout.cshtml file in Razor) with a just one PartialView for your menus/lins(lets say it MenuBar). Your _Layout.cshtml also should contains a #RenderBody which is responsible for different page contents.
After that you just create your pages and point them to user your masterpage (it is done by default by Razor). After that whenever you click on each link on your MenuBar , you redirected to the page which is pointed to.
At server and on rendering phase, The MVC starts to render the page from your master page (so it contains the Menu Bar automatically) and when it reachs the #RenderBody line , it renders your main page content instead.

I have a layout page within that layout I have used a partial view, the partial view contains a menu feature that I have built, I split the menu into a partial view to ensure it is easy to maintain. The menu has been purposely placed in the layout because it is used across every page, however there are conditional elements in the menu whereby some options only appear on certain pages.
I have stumbled upon what will be an issue for me moving forward, the menu uses ajax calls to render partial views containing the content (reducing page loads) I was just working on a page which contains a company, the company contains a list of contacts, the menu option when clicked should display the list of contacts. I have already loaded the contact list under the company model, but! I can’t access it from my new partial view that should render the contact list because the menu is a partial view that is contained within the layout page and as such cannot accept a model, so I cannot pass a model into the partial view I am trying to load because the menu partial view sits in the layout page.
This is a sticky situation, I obviously could change the layout to render a new section to contain the menu so I can pass a new view model into it but then every single page I build needs to reference the menu (what a pest!) I must be missing something here (considering this is my first MVC3 application that is likely). Any suggestions?
Edit: I took this further on my own, in short my layout page will always be able to access the model of the page that consumes it, as such my partial view which contains the menu can also access that data. I wrote some conditional logic in my menu partial view that checks the page and then passes in data as required.
<div class="menu">
<ul>
<li><a href="#Url.Action("Create", "Contact")">New Contact </li>
<li>Contact List </li>
</ul>
#if (Request.Url.PathAndQuery.Contains("/Contact/Details/"))
{
<ul>
<li>#Html.ActionLink("New Activity", "Create", "Activity", new { companyid = 0, contactid = Model.contact.id }, null)</li>
</ul>
}
</div>
The above is a small sample of the menu partial view but contains one example where the menu is built for the contact/details page and is able to pass in the model.contact.id. It works in that my menu and my layout do not explicitly contain a model, but it does not feel very tidy.
If I'm understanding your question correctly, your issue is that you don't think your Partial View can have a model because you don't want your layout to have a model. So the question is how can you get a model into your layout without needing every single action to extend this base model type your layout would use.
1) Instead of using Html.Partial in your layout for the menu use Html.Action where you'll then have an action method that fetches the menu data.
2) Write a custom WebViewPage and include a property that has something like
return ((BaseController)ViewContext.Controller).MenuData;
now you don't even need a model in your partial view, it can access the data directly.
Both of these require having a Menu property containing all menu information available in your base model, but if every page in your websites going to need to access this data, then that seems appropriate.
Edit: In response to your tidiness concern, it sounds like you want sections, which give you the ability to customize pieces of your menu either in their appropriate view page or sub layout.

I want to maintain the Scroll Position between two pages. I have a Page A which has many reports, when user clicks a report, user will be redirected to Page B where the report will be opened to make the changes. After submitting changes, user will be redirected to Page A. Here the problem is, showing the top of the page but I want to show the page at the previous position.
I have tried using this.MaintainScrollPositionOnPostBack = true; but this is working only on the same page but not between the different pages.
I really need to fix this, please give me your thoughts...
The simplest thing to do is probably give every link/report on page A an anchor.
So, for each report you would hide an id attribute somewhere - say the title, so it would be something like <h3 id="report42">Report 42</h3>. Then when you go back from page B, instead of going to www.example.com/pageA.html, you go to www.example.com/pageA.html#report42. This will open the page with the scrollbar at wherever the report42 id is found.
I am new to ASP.NET MVC and I have a question regarding viewing entity relationships.
Say I have an entity called 'Person'. This holds the usual data relating to a person (Name, Email, etc). I also have a 'Notes' entity. Under EF, a 'Person' can have many 'Notes'.
I have a Person controller where I can view and preform CRUD operations on a Person object.
I can show the notes in the view easily but what is the best way to allow a user to add/edit/delete these notes from the Person view? I am hoping to do this using AJAX and not have the user move to a completely different page to add/edit/delete a note.
Thanks in advance,
ViperMAN.
When they edit a note, popup a jQuery dialog pointing to your URL to edit or have a separate Ajax.BeginForm() on the page that the details go into. When they finish the edit call a method to refresh the notes.
So:
1. In your Notes grid (or whatever)
you have an edit link for each note called "edit"
this link looks something like the following:
This one actually uses 'notes' : )

ASP.NET MVC modal dialog/popup best practice
Also beware of this scenario for multiple links:
MVC3 - Only first row link works well with Jquery Modal Dialog
Now the urls you use to populate the dialogs would be for example
/Note/Edit/10
One thing to note - jQuery validation needs to know about these new items that are being loaded via ajax into the DOM , so in your partial view you need to tell jQuery validation to include the new items - I'll edit in a bit to add this, have to grab it from another machine.
I have a dashboard page which has 4 partial views.
each view has an edit link which when clicked, loads another temaplate.
Now ofcourse the new template will have Save and Cancel. When I click on cancel, i want to load the old view, and when click on save, i want to save the model and return to the old view.
all this has to be a partial update. How would i achieve this.
To start of with, i am using ajax action link (using post) to just return a datetime string. instead of updating my div, it is redirectin me to a different view.
MVC is ridiculously difficult. huh...
Ah.. MVC is simple once you establish a clean way to do things : )
so - each dashboard has 4 partials. So as one option - have your main page have four divs.
inside each div, use Html.Partial to render your views.
Each partial view has its own Ajax.BeginForm tag. The UpdateTargetId is the divs id in the parent view. I'm not a huge fan of a child needing to know the name of its parent to update, and there are some other ways (one option is each of the four views really is two other views for each one - one to contain the form and div that is updated and then a call to the partial view like:
Each 'parent' partial view has for example
<div id='divAddressEdit'>
#using (Ajax.BeginForm("action","controller", new AjaxOptions() { UpdateTargetId = "divAddressEdit", InsertionMode = InsertionMode.Replace }){
#Html.Partial(....)
}
</div>
Lets assume you go with the first option where each partial view contains its own ajax form.
So - when the user saves - ok.. the ajax form posts back, and then RedirectsToAction() and renders the new content again. When cancel is clicked, the same thing occurs - the form posts and you reload the original info.
The key here are the ajax forms. I know I didn't include much code here - as I believe your post is more of a conceptual question - if it doesn't make sense I'll post specific samples.
ASP.NET MVC noob here
I was writing a quiz application where a user can select her preferences (e.g. difficulty, number of question etc.), and once she hit a submit button - she got a new page with questions.
The preferences are represented as a "Preferences" object, and the questions are IEnumerable of Question.
This all worked well.
Now I decide both parts should be in the same page - and I don't know how to accomplish that:
Should I have a new model class that is a composition of these two parts?
And also - How will I make the "questions" part appear only after the user completed filling up her preferences and clicked a button?
Should I use AJAX?
I also read a little about partial views and RenderSection.. But I really couldn't understand which approach is the most appropriate for my scenario.
So how should I draw two parts of a page, where the second is only displayed after the first is submitted?
Thanks.
How familiar are you with AJAX? If I had to guess I would think a good way to do what you want to do is to have an AJAX call which is linked to an action when the user submits their preferences. The action can then return a partial view which you can have appear on the page without a reload via AJAX.
