What is the cleanest way to display a web page inside another web page. Currently I am using an I-Frame. But are there any current controls in ASP.NET to do this efficiently?

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.

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.
I am reading a tutorial article on this site about Partial Rendering using ScriptManager.EnablePartialRendering - [URL] The article uses button_click to demonstrate Partial Rendering without full page reload. I copy exactly the same codes but everytime I click the button the page refreshes.
I have examined after the page is loaded - ScriptManager1.EnablePartialRendering = true ScriptManager1.SupportsPartialRendering = true I am using vs2005 .NET 2.0 and AJAX extension 1.0 (same version as used in the article)
I have a master page with a partial view. I want the partial view to display only when viewing a specific page/action. Is there any conditional I can wrap around the partial view that checks for the page/action I'm viewing?
View 6 RepliesI am using an updatepanel and a grid is placed within the same.Now,I have a checkbox corresponding to each row of the grid.If I check it,say corresponding to one row and click a button(placed outside the panel), a popup will be opened which is a separate aspx page having its own functionality.
The requirement is like I need only the panel to refresh not the whole page.

I have an ASP.NET application which calls aspx-pages in other ASP.NET applications (all on the same server and the same solution). This aspx-pages should be shown in a (fixed) region on the main-site in that way that that only the embedded pages is renewed, during user interactions there. Is an IFRAME the only way to achieve this goal, or can I use for example theAJAX update-panel or are there further possibilities / techniques?
View 5 RepliesUpdatePanel1 contains dynamic controls and a Treeview,
UpdatePanel2 contains Image, and UpdatePanel3 contians dispaly information and several buttons. I set up the Triggers in the UpdatePanels.
however when I click one of the Buttons the dynamic controls in UpdatePanel1 get wiped out but the state of the rest of the controls seems ok. I would like for the dynamic controls to stay.
I have a page with a (gridview nested within a gridview) in an UpdatePanel (UpdateMode="Conditional"). The nested gridview drops down when you click on an arrow and then you can click on each subgrid rows command field. The gridviews are loaded from the Page_Load event. When I click on the commandfield in the subgrid the Page_Load fires during the partial page postback. From what I have read this is normal with UpdatePanels. But What I don't understand is why both Page.IsPostBack and ScriptManager.GetCurrent(Page).IsInAsyncPostBack test false after I click on the command field in my grid. I need to stop the rebinding of the gridviews ( which causes the subgrid to collapse ) when the command field is clicked.Also: I am using MasterPages and the <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> is located in my mater page form section.Would anyone have any suggestions how to test if a partial page postback is occuringHere is a link to the page source: http://pastebin.org/153774here is a link to the code behind: http://pastebin.org/153781

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.
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."
I have a table, there is a column for "edit links" - i'd like to render a partial view under the table via JQuery - but i think i'm missing a step:
Heres the html:[Code]....
I hardcode the link and make it call the "editCloset" js function, hopefully thatll call my Controller, thatll build the ViewModel, and return the View that uses it - so it can be rendered in the PartialView contained in div id="Slots"Right now - im not able to get into the controller, so i missing something i think Heres the controller:
[Code]....
And heres the partial view "_ManageSlots"
[Code]....
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.

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">
<contenttemplate>
<asp:panel id="pnlContent" runat="server" visible="false">
content initially hidden.
<script>
alert('done!');
</script>
</asp:panel>
</contenttemplate>
<triggers>
<asp:AsyncPostBackTrigger ControlID="lbtn"/>
</triggers>
</asp:UpdatePanel>
I need to save some information about user (some kind of statististics) on post back. But saving takes time and I don't want user to wait for this process. User does't need to know about that saving process.I'm thinking of using ThreadPool or Threads. I want page to be rendered right after I put saving function to the threadPool, not after saving was done.
View 3 Replies I know i could possibly just throw and exception and let the server handle the interruption but for personal knowledge and exploration, i would like to do it more than having the server automate it for me. I hav built a shared method that will take in information such as:
[Code]....
During the body, it just formats a series of information into a table and i would like to add the table to the page. Now i know you just simply do "Page.Controls.Add(Object)" to add the table to the page. Problem is that it adds it to the bottom of the page after rendering all the other content.
I would like for this method to interrupt the rendering process, clear out what has been built up and then output the table to the substitute the page pre-defined content.Very similar to what IIS spits out when it encounters and error and show the Exception name, message, and stack-trace. Although my exception is by no means that complicated.
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.
partial rendering using update panel .I was wondering when a control is clicked in an update panel does the entire page is sent as an asynchronous call or the just the content of the update panel , the server process the entire page or just the update panel content that is being changed.
View 3 RepliesI have several datalist controls inside a panel control.
When I do a databind on the "movie" datalist, data is populated. I can see during the debugging on the aspx page that it goes into the label controls and binds the data.
When I do a databind on the "alacarte" datalist, the data isn't populated even though before doing the databind I validate that there is a record inside the generic collection that I use for each separate type of datalist. When the databind occurs, it goes thru the alacarte datalist and does the databinding to the fields, but when the page renders, it doesn't produce any output inside this datalist.
The code behind below is the databinding for the movie datalist.
DataList grdMovies = ShoppingCart1.FindControl("grdMovies") as DataList;
grdMovies.DataSource = lstMovies;
grdMovies.DataBind();
The code behind below is the databinding for the alacarte datalist. I verified that there is a record inside the lstAlacarte collection with the same field names that are in the html for the alacarte section during the databinding.
DataList grdCartAlaCartePgming = ShoppingCart1.FindControl("grdCartAlacartePgming") as DataList;
grdCartAlaCartePgming.DataSource = lstAlacarte;
grdCartAlaCartePgming.DataBind();
Below is the html on the aspx page for the above controls. I included all of the html so as to see if there is anything I'm doing wrong. I even placed the words "desc" and "price" to see if that would render and it did not.
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ShoppingCart.ascx.cs"
Inherits="DishRedesignClient.ShoppingCart" %>
