MVC :: Multiple Views Render As A Single Page?
Mar 20, 2010
I have an MVC 1.0 project and I have created an IView extension so I'm able to render also xslt in addition to normal view form.
the content of each page must be dynamically changes (more or less a CMS), so I write some slots of content (xslt views) and I want to render one or more of this slots into a single page.
It easy to render just one, withe the viewextension or via partial render .. I dont know how to render more than 1. In classic asp the first option should be a virtual include. How can i do that? or smoething similar?

I'm using the ReportViewer control on my .aspx page which displays a single report based on various user parameter selections. Dropdown2 is dependent on the DropDown1 selection (i.e. the user selects Unit A from DropDown1 and that results in 10 selections under Dropdown2, or the user selects Unit B from DropDown1 and that results in 15 selections under DropDown2, and so on). The user makes the selections, clicks the "Run Report" button, and the report displays as expected. The user then can export to Excel or PDF
I've received a request to allow users to run the report for all possible selections and export to their desired format rather than having to run the report for each separate DropDown1 and DropDown2 selection. So in other words, they don't even want to see the report on the screen, they just want to be able to click a button that runs the report for all possible parameter selections and export it to a single Excel or PDF document.

I have an application that needs to render a page that will have multiple Radio Button Groups as well as multiple CheckBoxes. The desired layout is determined by a database table.
table structure:
PackageID uniqueidentifier
PackageName string
ItemName string
RadioGroupName string
ViewControlName string
This table defines a "Package". The "Package" can contain many different "Items" that require different controls used in the View. The "RadioGroupName" field is used to mark which RadioButtons should be grouped together. The "ViewControl" field marks which control should be used on the View to display the field. The query in my repository will return a result set such as
1 / "First Package" / "Item1" / "First Group" / "RadioButton"
2 / "First Package" / "Item2" / "First Group" / "RadioButton"
3 / "First Package" / "Item3" / "First Group" / "RadioButton"
4 / "First Package" / "Item4" / null / "CheckBox"
5 / "First Package" / "Item5" / null / "CheckBox"
6 / "First Package" / "Item6" / "Second Group" / "RadioButton"
7 / "First Package" / "Item7" / "Second Group" / "RadioButton"
8 / "First Package" / "Item8" / "Second Group" / "RadioButton"
Given this result set, I need to render the view as follows:
A RadioButton group with 3 options (Item1, Item2, Item3)
A CheckBox (Item4)
A CheckBox (Item5)
A RadioButton group with 3 options (Item6, Item7, Item8)
I have read that it is possible to use "if" conditions and looping structures inside the View. I have also read that this is a bad practice. Another issue I see is knowing which Item has been selected from each RadioButton group when I hit the Controller POST function. Previously I have built a page that has a single RadioButton group. My ViewModel was as follows:

I have view that dynamically adds multiple partial views with a foreach statement with the standard <%Html.RenderPartial("partialName", model); %> . The partial view control has just a label and textbox control. When I view the source html generated it correctly has a single form control around all the multiple labels and textboxes. My single submit button, inside the form though does not send any of the form data back to the controller though when using FormCollection.

I am using tabs and I want some user input on each one.hen I click submit I return the partial view. However it is only the partial view that gets rendered.What I am trying to do is keep the overall view and render the partial view. In fact what I am trying to do is known as hijaxing, but I am not familiar enough with Ajax that I know how to do it.So this is my view;
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Employee.Master" Inherits="System.Web.Mvc.ViewPage<SHP.WebUI.Models.HolidayRequestViewModel>" %><asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> HolidayRequest</asp:Content><asp:Content
ID="Content2" ContentPlaceHolderID="EmployeeContent" runat="server"> <% using (Html.BeginForm()) {%> <%: Html.AntiForgeryToken() %> <h2>Holiday Request</h2> <p>You have <%: Html.DisplayFor(model => model.DaysAvailableThisYear) %> days left annual leave for this year and <%: Html.DisplayFor(model => model.DaysAvailableNextYear) %> days left for next year.</p> <p>If your request is approved and exceeds the number of days left, then those extra days will not be paid.</p> <%: Html.HiddenFor(x => x.EmployeeId) %><%: Html.HiddenFor(x => x.ApproverId) %> <% } %> <div id="tabs"> <ul> <li><a href="#tabs-1">Approver</a></li> <li><a href="#tabs-2">Single Date</a></li> <li><a href="#tabs-3">Date Range</a></li> </ul> <div id="tabs-1"> <% Html.RenderPartial("GetApproverTab", Model); %> </div> <div id="tabs-2"> <% Html.RenderPartial("GetSingleDateTab", Model); %> </div> <div id="tabs-3"> <% Html.RenderPartial("GetDateRangeTab", Model); %> </div> </div></asp:Content>
This is my partial view;
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<SHP.WebUI.Models.HolidayRequestViewModel>" %><% using (Html.BeginForm("GetSingleDateTab", "Employee", FormMethod.Post, new { id = "frmSingleDate" })) { %><p>Enter your day or part day of Annual Leave here.</p><table> <tr> <td align="right">Date:</td> <td><%: Html.EditorFor(x => x.SingleDate) %></td> </tr> <tr> <td align="right">Morning Only:</td> <td><%: Html.CheckBoxFor(x => x.MorningOnlyFlag) %></td> </tr> <tr> <td align="right">Afternoon Only:</td> <td><%: Html.CheckBoxFor(x => x.MorningOnlyFlag) %></td> </tr> <tr> <td colspan="2" align="center"><input type="submit" value="Save" /></td> </tr></table><%: Html.HiddenFor(x => x.EmployeeId) %><%: Html.HiddenFor(x => x.ApproverId) %> <% } %>
and this is my controller;

I have an existing asp.net web application I am redesigning to use a service architecture. I have the beginnings of an WCF service which I am able to call and perform functions with no problems. As far as updating data, it all makes sense. For example, I have a button that says Submit Order, it sends the data to the service, which does the processing.
Here's my concern: If I have an ASP.NET page that shows me a list of orders (View Orders page), and at the top I have a bunch of drop down lists for order types, and other search criteria which is populated by querying different tables from the database (lookup tables, etc). I am hoping to eventually completely decouple the web application from the DB, and use data contracts to pass information between the BLL, the SOA, and the web app. With that said, how can I reduce the # of WCF calls needed to load my "View Orders" page? I would need to make 1 call get the list of orders, and 1 call for each drop down list, etc because those are populated by individual functions in my BLL.
Is it good architecture to create a web service method that returns back a specialized data contract that consists of everything you would need to display a View Orders page, in 1 shot? Something like this pseudocode:
public class ViewOrderPageDTO
{
public OrderDTO[] Orders { get; set; }[code].....
Or is it better practice in the page_load event to make 5 or 6 or even 15 individual calls to the SOA to get the data needed to load the page? Therefore, bypassing the need for specialized wcf methods or DTO's that conglomerate other DTO?

I have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.
While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.

I'm looking at doing a pair of MVC applications. One of the application will be a public website and the other for a POS kiosk. There will be some common views between the two applications. I'm considering having a single Visual Studio solution that will contain the two projects. But, I'm not sure how I can go about sharing the common views between the two projects, without just copy and pasting.
Is there way of doing it? Or should I be looking at using a different approach?

This is my first forray into ASP.NET MVC, having been doing WebForms for nearly 6 years now. I've read through various tutorials and guides on getting started with MVC, but I've a few questions about how you're meant to do things:
UserControls for entities
In an application I wrote a few years ago (using WebForms) there were many entities that had an associated postal address (which existed as an instance of an Address class), so I created a UserControl that contained fields for working with addresses. During the page lifecycle I would pass the business object's .Address property to the UserControl for display and for population upon a successful and valid postback. How would I do something like this in MVC? My current project has a similar situation where common sets of fields are repeated throughout the application and all 'map' to the same class.
Modifying the page/view on 'postback'
Say I'm working on a data-entry form for an online B2B ordering system, where the user manually enters order items into a series of textboxes arranged in a table. The system can only provide so-many textboxes at a time (usually 5 or 10). If the user ran out of textboxes they would click an "Add more rows" button that performed a postback that was caught by that button's server-side .Click event handler. The page's class would then add more rows to the page; ASP.NET's stateful nature made this easy to implement. But in MVC there is no ViewState and I haven't found much information about how you'd do this, or anything like this. All of the tutorials and guides assume a form posting is only for data submission.
Multiple tasks per page/form
In a similar vein to the above, how do you create views that perform multiple tasks? In my above example I cited a webform that had two buttons: one to submit the form for actual processing, and another button that just modified the page (by adding more data-entry rows).Given that Controllers' actions are bound to URIs rather than what combination of fields were submitted, does this mean that I would have to interpret the posted data myself and branch based on that?
Componentised self-contained controls (e.g. sidebar forms)
Finally, in many web applications you have the main form in the middle, but also things on the periphary of the page (e.g. a sidebar) that might have their own logic. For example, in one WebForms application I wrote last year there was a 'Quick contact' form in a UserControl located elsewhere on the page. When the user clicked the form's button the UserControl's logic handled the postback details independently of the page containing the UserControl (but there was only one <form> element in the whole rendered page). The user was returned to the page they clicked the button on, with everything in identical state as to how it was before, exccept for the UserControl which reported that the email was sent. Again, MVC's stateless nature would make something like this hard to implement, unless there are some techniques not covered in the tutorials?

I'm working on a webforms aspx app (not MVC) and I'm not sure if I should just create separate pages or somehow make multiple views on the same aspx page for the following scenario: Basically, I need to give the user the option to view a set of data a few different ways (essentially different group by's from a data perspective)... the data is always the same, its just a matter of how to arrange on the page...
each way I need to present the data will essentially consist of 2 repeaters, one nested inside the other. The outer repeater will display a nice header section with the nested repeater showing the list of items under that heading. view by book title (title is outer repeater, with the book list being the nested repeater, yes, multiple books with same title for this example - the app has nothing to do with books, this is just to illustrate)
Book Title: A Good Story
Author - Publisher - ISBN
Dan Johnson - Smith Publishing - kjdkjfd99898989
Susan Day - Smith Publishing - aa777fd99ff

Or, view books by publisher (here the publisher would be the outer repeater and the list, with different fields compared to first view, is the nested repeater.
Publisher: Smith Publishing

so what do I do here? Just making separate pages is simple and would work, but is there something else I should be considering? There will be 3 different views, so 3 pages total if I went that route. Something is making me think I should be doing this all within one aspx page? maybe just toggling the visible property of the repeater controls? but then I was thinking each of these repeater controls is databound, and I assume even if they are not visible they still incurred database hits to get the data, right? and that could be bad?

If I have a View for 'People' and a View for 'Company' and each has an associated list of 'Orders', should there be a separate view for each? Such as /People/Orders and Company/Orders, or should I simply have a single /Orders views and pass in some parameters?

It's a multi-model view, and I'm achieving this through an IList<Book>. Each Book has a Title and an Author
So for example if I wanted to make 3 Books:
[code]....
However, I want to be able to generate such a form for any number of Books. I've done this before in Ruby on Rails through JavaScript and rendering partials, but I don't think I can render a partial in this case because the form changes (the index of the book has to increment for it to work)
EDIT: I'm looking for a way to do this in the Create view in particular. So in this case I don't have a list of books, but I'm building it.
A user should be able to click on a link that says "Add another item" and a form for another book should be appended to the bottom.
