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. 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 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 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.
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 RepliesWhat 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.

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?
[Code]....
i got a strange problem. my project was ok before implimenting ajax. i have just implimented ajax in one page only with Tabcontainer and updatepanels only nothing else. almost all controls are devided into different Tabs with respective update panels.
mostly it is working ok. but the problem is :
1. in some controls i am not able to write anything even the control is "Enabled=True" and focus is on the same control after partial postback.
2. and as soon as i press Tab control goes to Address bar.
3. some time tab key is also not working.
here some code :
[Code]....
Here the Logic :
as soon as i type inception date; expirydate is automatically calculated and focus should come to sumassured. after this it should allowed to enter sumassured amount, which is not allowing to write.
As soon as i change tab and come back to original tab then i can write values normaly.
I've created a dynamic button from another control outside of the update Panel. The button is given an ID and such. When the button is click, a postback occurs and I've re-created this button during Page_Init, Page_PreLoad, and Page_Onload and NONE of them is preserving the value.
The only way for me to find the control was to look at the Page.request.form's allkeys and compare the string with a any text string that contains: Button. Because I ID'd teh button as: ButtonRow_0Col0. But the actual ID is null. However, when traversing through page.request.form, the allkeys shows that ID with no problem.
So how come the actual ID is lost after a partial postback yet, the page.request.form's allkeys can pull out its allkey's value??
I want to make auto partial page refresh in asp.net. There is UpdatePanel but it sends too much data. So I've found that I can make a webservice and call it by the JavaScript code. But I don't know how to call webservice automatic. There are many examples showing how to call webservice by the button click event:

How to do this by the interval? Am I going in good direction?
I have a simple form (textbox, submit button) which is wrapped in an update panel.
[Code]....
I type some text in the textbox, click submit, then the server creates a database record and returns an object, which has properties like ID, Name, URL, Blah, etc. These are the values that the script requires.
So if i were to call a web service from the client-code, in order to get the values that were just created, i would need to do some hacks (get last record modified that has the value of the textbox). Not ideal, and neither is two AJAX calls for one form post. (update panel postback, then web service call).
I've implemented a Wizard in which most steps are UserControls. One of these steps contains a DropDownList and a RadioButtonList. Depending on the item selected in the DropDownList, some items in the adioButtonList are disabled or enabled via a callback. This works fine.
Then I added a ToolkitScriptManager to the page (EnablePartialRendering="true") and wrapped the controls in this particular step in an UpdatePanel's ContentTemplate. Running inside of VS2008, the appropriate radio buttons are disabled or enabled as expected in response to changes in the DropDownList without a full page refresh. It feels much more response and looks slick.
Then I deploy to the test server and suddenly the partial-page refresh is gone, the whole page is redrawing as though the script manager and UpdatePanel hadn't been added.
I've tried several variations on this, always with the same result. For instance - I moved the DropDownList outside of the updatePanel and added an AsyncPostbackTrigger for the DropDown's SelectedIndexChange event. No change - works in VS2008 but not on the server. - I added ChildrenAsTriggers="false" UpdateMode="Conditional" to the UpdatePanel, both with the DropDown inside the UpdatePanel and outside the UpdatePanel. No change - works in VS2008 but not on the server.
I have a linkbutton inside a updatepanel and when the update panel does a partial page rendering, the linkbutton disappears.
<asp:UpdatePanel ID="up" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="drp" runat="server" AutoPostBack="true" CausesValidation="true">
<asp:ListItem Text="" Value="" />
<asp:ListItem Text="a" Value="a" />
<asp:ListItem Text="b" Value="b" />
<asp:ListItem Text="c" Value="c" />
</asp:DropDownList>
<asp:LinkButton ID="link" Text="abc" runat="server" />
</ContentTemplate>
I think that is because the link button is rendered using a script and that script is not run after the post back.
I am having problems selecting the text within a TextBox in an UpdatePanel in IE 8. Consider a very simple page that contains a single UpdatePanel. Within that UpdatePanel there are two Web controls:
A DropDownList with three statically-defined list items, whose AutoPostBack property is set to True, and
A TextBox Web control
The DropDownList has a server-side event handler for its SelectedIndexChanged event, and in that event handler there's two lines of code:

The above functionality is not working when we place dropdownlist and textbox inside updatePanel and ModalPopupExtender

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 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:

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.
I am currently using a asp.net 2.0 with visual studio 2005.
I am trying to build a web application using ajax.
but when I drag the ajax updatepanel on asp.net page it is not resizable,so how should i put other controls on it?
