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.
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 had successfully created a functionality where I can dynamically add rows and columns to a asp table by creating/re-creating controls on every page load.
I have 2 buttons - Add rows and Add columns that, basically according to a asp.,net page life cycle, occur in the following order and work perfectly fine.
Page load is fired and controls along with their viewstate are recreated. In Add row button click event - I just create a new table row and add controls to each cell dynamically.
Same thing with Add column, Delete Row and Delete Column button click events.
However, now I added a Dropdown which when its index is changed needs to retrieve values from the database and create controls based on those values and then also bind the Db values.
But it doesn't work correctly since the asp.net page cycle cannot capture the dropdown's selected value in page_load as the page_load fired first and then the selectedindexchanged event is fired later, the controls are not created.
I don't know how to handle this scenario and incorporate it into my existing code.
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>
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.
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 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. On top of the table i am using updatepanel for partial page rendering. When i select a row from gridview the text boxes are not populating, the table disappears.Below is the code

I have a user control.
On that user control is an update panel.
In that update panel is a wizard.
One of the steps is as follows.
[Code]....
What this does is create a javascript spinner control. Now when I click the NEXT button onto this step it generates the spinner control. I click next to go to the next step, then I click PREVIOUS to go back to this step and the spinner control is not generated.
Now I have tested this on an ASPX page and it seems to work, I then copy the code across to an ASCX control and put the page live and it does not work.
The update panel has an animation extender that just displays a div with a processing gif when you click next/previous.
So any reason why it creates the control on the next and not the previous step?
I am using two user controls in my page. The controls are loaded dynamically one at a time. I'm just referencing the user controls in the page and loading them dynamically using 'LoadControl()'. Everything is working fine till now and the user can switch the controls one another.
Here the issue I found is eventhough the controls are working as expected and the data is visible, the rendered HTML contains only the first loaded user control's markup.
Even if the current control displayed is 'usercontrol2', the source shows 'usercontrol1' markup. How can I force the page to render 'usercontrol2' markup and remove 'usercontrol1' markup while loading'usercontrol2'?
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 have a View that renders something like this:
"Item 1" and "Item 2" are <tr> elements from a table.
After the user change "Value 1" or "Value 2" I would like to call a Controller and put the result (some HTML snippet) in the div marked as "Result of...".
I have some vague notions of JQuery. I know how to bind to the onchange event of the Select element, and call the $.ajax() function, for example.
But I wonder if this can be achieved in a more efficient way in ASP.NET MVC2.
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 page has Listview and Datapager inside UpdatePanel. When I refresh the new SQL results and bind by pressing link buton outside of the update panel, I get correct results. (get new SQLselect statment, rebind to listview, update updatepanel)
However, the SelectCommand is not bound right or some other reason, if I press datapager, I won't get no results.
I'm guessing it's caused by not passing new dynamic selectcommand since my datapager and listview works first update.
I have created a class UserDetailsModel.cs in my folder model. I have populated a selectedList in the model class.

I need to display an error message in the view when there's an error in rendering the partial view in that View.
How can i handle the exception while rendering partial view and display the error message in the view?
Issue:
As my pages are taking time to load first time.
So user has to wait till full page gets loaded and thats irritating . Was this the reason MVC was evolved?
Solution :Should i use partial rendering on all pages including home page, and all forms getting called from home page.
So even if half page is loaded thats less frustrating
For Partial rendering what i plan is : i will put Scriptmanager with Enable partial renderingand update panel for half part of page.
So that user dont have to wait for full page to load.
Is my plan correct? Problem is i cannot regenerate page load issue every time.
i have an Async JQuery Treeview working, but in addition to filling out the tree - id like for every node expanded to update part of the page with information as well - is this possible?My View looks like this:

I have a partial view which uses Ajax.ActionLink to perform paging. The AjaxOptions in the link identify the update target (a div on the main view) and some javascript to run OnSuccess (in the partial view). The javascript must be in the partial view since there is some information in the partial view required to properly wire up the jQuery in the javascript. This isn't working as expected. The sample below is the minimum code to duplicate the behavior I am seeing:
Controller:
[Code]....
View:
[Code]...
Partial View:
[Code]....
I would expect that the value shown in the javascript alert would increase each time you click the link. I put in a break point and made sure the value was incrementing so it is definitely a problem in the ajax side. Is this by design? If so, what is the recommended work-around.
