.NET AJAX Partial Rendering?

Mar 15, 2010

I have a question about how ASP.NET AJAX partial rendering actually works. Does it:

1) Renders the whole page on the server, transmits the whole page to the client, the client then merges just the area contained in the update panel.

2) Renders the whole page on the server, transmits and merges just the area contained by the update panel.

3) Renders, transmits and merges just the area contained by the update panel.

AJAX :: Facebook Wall Style Partial Page Rendering?

Jan 31, 2011

I have to create facebook style wall in my project. So far I assume that I will get X(the number that needs to be shown be default) number of wall posts from database, bind them to some control like Repeater and add update panel in each row in repeater so that only the portion of page only related to that post is updated once any new comment is added in that post.

Now, since I am new to AJAX so cant figure out how to display the "older post" link functionality there. As we have link at the bottom of facebook wall which once clicked appends the certain number of older posts at the end of the wall.

Similarly, once a new post is added by someone, it gets added at the top of the wall, how can I acheive that so tha only the limited portion at the top of the wall gets refersed and updated instead of whole page post back.

Apr 15, 2010

Initially i was planning to use master page for every page in my application. At the end, i found out every times the page is changed, it reload full page even it have the same master page. I have confused the frameset with the master page. Then, i have 2 in my minds to achieve it by not using master page.

Using iframe and set the attribute to runat server, so that i can change the page in my codebehind.(I preferred to control the page flow in server side)Make every single child page to user control. Then dynamically load it to the panel in codebehind.

Jun 25, 2010

I am trying to render a partial view and i can not get it to work. Probably i am missing something trivial, because what i am trying to do is really simple.

I have two controllers: NewsController and CommentController. In the "Details" view of the NewsController i'd like to render the partial view "List" of CommentController. So in Details.aspx i have this line:[Code]....

However, this line throws an excpetion:

"The controller for path '/News/Details/e4243192-55ea-4cfb-b8d3-9714cca4ff08' was not found or does not implement IController."

And heres the partial view "_ManageSlots"

MVC :: Conditional Partial View Rendering?

Nov 25, 2010

Just to get it work, I got a controller action that make use of a switch statement to decide which partial view to render, based on one of the members of the model passed in. (Written by someone else for what it matter...I'm just cleaning up)

The viewmodel is overcomplicated, but that's not my decision right now and just have to live with it.

All partial's get rendered passing the same viewmodel, just a different partial get called.

Javascript Not Executing After Partial Rendering?

Nov 15, 2010

I have a asp.net panel that is initially hidden and is shown when a button is clicked. There is javascript inside that panel and it doesn't execute after the panel is set to be visible. I can see that javascript function gets outputted on page but it is not called. What can I do to make it so that function gets called? Here is an example:

<asp:LinkButton id="lbtn" runat="server" Text="show" OnClick="lbtn_Click" />
<asp:UpdatePanel id="upnl" runat="server" UpdateMode="Conditional">
<asp:panel id="pnlContent" runat="server" visible="false">
content initially hidden.

C# - AJAX Partial Page Update When Displaying A Control?

Mar 8, 2010

I have an interesting problem when using partial page update in asp.net with scriptmanager and a update panel.

My scenario looks like this: I'm using the tab control from the ajax toolkit. I also implemented this control using lazy loading, so that when the page is loaded only the current tab gets loaded all the other tabs don't get rendered, because Im using an UpdatePanel (on a .ascx control) on each of these tabs and when a tab gets selected the updatepanel makes a async postback to load the content for a selected tab.

On one of my tabs Im using a combobox control from obout.com, and it doesn't work. Now I know why it doesn't work. It doesn't work because the control is shown via a partial page refresh, but to correctly display the control it has to do some "magic" that is - register some .css and .js includes on the page (in the head I guess)....but because I load this control via async page refresh.

MVC :: Partial View Not Updating (trying To Make AJAX Update)?

Jun 28, 2010

I have a table of data from which I am trying to delete a single row using jQuery. While I am having no problems getting a POST delete to work, Iam having issues getting the partial view to update properly to reflect the deleted data.The table resides in a strongly-typed view, Errors.ascx, which is called in my Index.aspx page. Errors.ascx is nothing special, just a table where each row has a delete button that looks like this:

MVC :: Asynchronous Partial Rendering In View Page

Nov 24, 2010

What is the best way to build a progress page? In short, I want a user to complete a series of "setup steps" and hit a "Start" button. I would like them to be immediately redirected to a "Progress" page that will show them the progress of each step. In my case these would be: Shutdown device, copy file, Start device.

My approach so far is to build a Progress View page and use partial views. Here is what I have so far. I would like the Progress page to show up right away even if the ShutdownStatus View has not finished rendering. At some point, I plan on including a progress bar but right now I'm just curious as to how I can show the Progress page immediately then show each partial View as it completes.


<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

MVC :: Rendering Area Partial View From External Dll

Nov 25, 2010

I am quite new to MVC and am gradually overcoming all my 'but WebForms can do that' issues but I still have one. I wish to have components which I can deploy into an Area in order to keep things nice and tidy. This area will have a bunch of re-usable partial views like this. MyArea/Views/Shared/MyAreaControl.ascx I can render this MyAreaControl partial view fine in other Views inside that area but it fails when I try to render it from a not inside the area (e.g. view in the root of the site). I am essentially using this syntax

<% Html.RenderPartial("MyAreaControl", new { area = "MyArea" }); %>

which seems to only look for this partial view inside the root Views folder, not the area one despite me specifying the area. Is this a restriction of the system, a bug - or am I just doing it wrong. ADDENDUM: Turns out it appears to be an assembly issue. My controller is found in a separate assembly from my MVC Application. Doing a bit of fiddling with moving my control inside and outside of the area and the separate dll I came to the following confusion:

- If partial view is in its own area and the controller is part of the MVC application dll - I can render it from my home view
- If partial view is not in its own area and the controller is part of an external dll I can render it from my home view
- If partial view is not in its own area and the controller is part of the MVC application dll - I can render it from my home view
- If partial view is in its own area and the controller is part of an external dll I CANNOT render it from my home view

The controller for path '/' was not found or does not implement IController.
