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 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 using a table and within the table i have gridview and textbox controls. On the rowcommand i am populating the data in text boxes.

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)
how to catch update panel's request start (before partial updation request is sent to server) and response receive (before update panel is updated) events.
View 1 RepliesI am building a system for a school project. I currently have several Update Panels on the page that have many different controls on them. I also have a single Label control that i use to display messages to the user. I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?
View 2 Repliesi am confused about the fact that if partial update of dropdowns is possible through Update Panel ,then why we should use asp.net ajax Cascading drop down extender ,that has made same task bit complex by making callback to web services ? what is difference between using update panel and cascading drop down extender ?

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.
i have one label out of update panel and one button inside update panel. in button click event i update the label text. when i run the code and click on button then partial postback occur and button click event fire but label value is not change. if i put the label too in the update panel then label value change at the time of button click. i do not understand why label value is not getting updated. suppose if i want that label should stay out of update panel and label value should change at the time of partial postback then how to write the code. i dont want put the label in any update panel.
View 5 RepliesI 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 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 RepliesI 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 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.
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:
public ActionResult Delete(Guid id)
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 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.
UpdatePanel1 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.
