I know about Always vs. Conditional, I just need to know exactly which update panel's data needs to be refreshed (not taken from app tier cache) on the serverside.

I have a series of div's inside an update panel, these divs have a margin-bottom defined in css. In IE8, when I do a async postback these margins are all removed. All the other styles are fine. If I turn on compatibility mode this does not happen. In Google Chrome the margins are maintained correctly after the async postbacks.

I've got a problem that after i refresh an update panel all the HoverMenu's stop displaying, it still calls the WebMethod which returns valid html and the panel is displayed, but it content of the panel isn't displayed on the browser.
I've created a single page to demo this problem:
aspx
[Code]....
vb.net
[Code]....
The demo shows the hovermenu working until you click the update button then it stops showing the content, although it is still calling the WebMethod onhover.
I am using VS2008, .net Framework 3.5 and toolkit 3, 0, 30930, 0

On my MasterPage I use UpdatePanel to update whole ContentPlaceHolder. Example of code you can find below. All content pages work fine with this MasterPage except one. This page is very complex. I noticed that when I disable UpdatePanel in my MasterPage this problematic page works fine. Question: is it possible to exclude something from UpdatePanel - in my example whole page but only this one?
<asp:UpdatePanel
ID="UpdatePanel2"
runat="server">
<ContentTemplate>
<asp:ContentPlaceHolder
id="MainContent"
runat="server">
</asp:ContentPlaceHolder>
</ContentTemplate>
</asp:UpdatePanel>

Does anyone know a simple way to determine if a user control is contained in an update panel that was triggered for async postback?
At the moment, the only pseudo logic for this I can think of is?
'Loop through the update panel controls on the page and find the one that is involved in the postback (isInPartialRendering)
'Try to find the user control as a child of the update panel

Is something like this possible?
Dim iCounter as Integer
Dim iQuantity as Integer = 10
Protected Sub btnFoo_Click Handles btnFoo Yadda
For i as Integer = iCounter to iQuantity - 1
//do something with AsyncPostBackTrigger until iCounter = iQuantity - 1
//then trigger a full postback
Next
End Sub
I am new to the concept and feel like there must be something really easy that I am missing.

Here is the code. On button click it should perform async refreshing. Instead it does a full page postback.

Am I missing a trick here ???
I am using VWD 2008.. I have a RadioButtonList with two options.
[Code]....
I also have an UpdatePanel
[Code]....
When the LoadingOption change it then has some code behind that at the moment changes the <asp:Literal ID="ItemName" runat="server" /> text.
If I don't have a Radiobutton selected when the page loads then all works fine. i.e. I can select either radiobutton and the ItemName updates correctly.... Whats the problem you may ask ????
Well I want to have one of the Radio buttons selected when the page has been loaded (like a default setting). So I do this <asp:ListItem Text="1kVA" Value="1kVA" Selected="True" />........ Here is my problem, When I select the other option (7kVA) the ItemName updates fine BUT if I then select the first option (1kVA) the ItemName does not update. I added another button that just does a postback. When the button is clicked the ItemName updates correctly. OK, fine but I don't want that. I want to be able to click on one option and the ItemName updates then click on the other option and the ItemName updates.
Have I missed something out ??
By the way if I set the <asp:AsyncPostBackTrigger ControlID="LoadingOptions" /> to <asp:PostBackTrigger ControlID="LoadingOptions" /> then it works how I want it apart from the reloading of the page, I would like it to update in Async Mode so it is seemless and no page reload.

I am searching already the web for some hours to get this working. I created a custom control (ConfigTree), which has a treeview as part of it. I put the custom control into an update panel. So far so good. When I click on different buttons (in ucc:ConfigTree) or the treeview in the custom control an async postback is done. When clicking on a node in the treeview an event for the parent element (ConfigTree) is generated, which populates again an event (NodeSelected) for the parent element (shown below). Different parent elements can handle the event differently. In one element (this one) I need to transform the async postback in a real postback with full page refresh. For better understanding see the following code:
[Code]....
the parent element (here shown) should process the OnNodeSelected and transform it into an full postback and not just an async postback, but only this event, all the other events in the ucc:ConfigTree should processed async. How can I do that? Is there a method to call in the code behind?

I have a MVC view, say,:
[Code]....
somepartialview calls other partial views, that also contains client javascript. This loads and works fine, the javascript-based effects (vertical ticker, horizontal ticker) work fine as well.
The problem is that somepartialview has several AJAX.ActionLink(s) like this:
Ajax.ActionLink("LinkText", "SetIcons", new { id = l.ID }, new AjaxOptions { UpdateTargetId = "ajaxdiv" })
Namely, an <a> element which upon click changes the content of <div id="ajaxdiv"> using a 'SetIcons' controller:
[Code]....
But this works only partially: the page gets refreshed with the new HTML content, but the scripts that worked before the async postback do not run anymore. How do I get them to work?
I think that I am looking for the MVC alternative of the WebForms' ScriptManager.RegisterStartupScript
OSDBDataContext db = new OSDBDataContext();

I have a web application that does some complicated data retrieval tasks and so I am trying to show a modal dialog box with a loading message when the tasks begins. I am using ASP.Net 3.5, the jQeury popup I am using is bPopup.
Firstly, I have a table where the rows can be clicked. Im am using a script from[URL] to do an async postback from the table row. Here is my function
[Code]....
so the $("#<%=lDiv.ClientID %>").openPopup(); opens up my loading modal and then the server starts doing its thing. When the server finishes though how would I then close the dialog box?
I just need to call one line of code like $("#<%=lDiv.ClientID %>").closePopup();

I'm working on adding a todo list to a project system and would like to have the todo creation trigger a async postback to update the database. I'd really like to host this in a usercontrol so I can drop the todo list onto a project page, task page or stand alone todo list page.
Here's what I have.User Control "TodoList.ascx" which lives in the Controls directory.
The script that sits at the top of the UserControl. You can see where I started building jsonText to postback but when that didn't work I just tried posting back an empty data variable and removed the 'string[] items' variable from the AddTodo2 method.
<script type="text/javascript">
$(document).ready(function() {
// Add the page method call as an onclick handler for the div.
[code]...
I can have a control that can be used to display multiple todo lists and create a brand new todo list as well.When I click on the #divAddButton I can watch it build the postback in firebug but once it completes it runs the error portion by alerting 'error'. I can't see why.
I'd really rather have the response method live inside the user control as well. Since I'll be dropping it on several pages to keep from having to go put a method on each individual page.

I am creating a ASP.Net server control to manage locations. The control is a composite control containing several text-boxes, labels, and a link button. I use the AJAX Control Toolkit to provide a modal popup which contains a Bing map. All the Javascript is in its own file and used as an embedded web resource.
The link button is what opens the modal popup. It also needs to call a Javascript function that initializes the Bing map (onclick = "GetMap();"). There are instances when this server control is placed within an Update Panel (and there is no way to avoid this). When in an Update Panel the link button loses its onclick event. I understand that this is because during an async postback the portion of the DOM that defines the content of the Update Panel is thrown out and reinitialized, resulting in the event breaking. When the control is not in an Update Panel everything works as intended.
I have tried registering events on Page.Load and Page.Init, like so:
[Code]....
I have also tried flat out writing the function call to the page:
[Code]....
I have put breakpoints on the lines inside each delegate and they do not get hit. I am not aware of any special way to register events of a composite control's child control or the Page.Load/Page.Init events when being done inside a server control. Is there some special way to register these events? (Note: Both those code blocks above are in my CreateChildControls() method)
Below is the GetMap() Javascript function. As you can see it is pretty straight forward.

I want to provide status updates during a long-running task on an ASP.NET WebForms page with AJAX.Is there a way to get the ScriptManager to execute and process a script for a web service request concurrently with an async postback? I have a script on the page that makes a web service request. It runs on page load and periodically using setInterval(). It's running correctly before the async postback is initiated, but it stops running during the async postback, and doesn't run again until after the async postback completes.

I have a GridView within an UpdatePanel - <asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="true">
Without listing any Triggers, I get a full postback when I visit a particular row within the GridView and click the 'Edit' button for that row.
However, if I enter the following trigger...
<Triggers>
<asp:AsyncPostBackTrigger ControlID="GridView1" EventName="RowEditing" />
</Triggers>
...I get an async postback when I click the 'Edit' button for a particular GridView row. This is what I want. In fact, I also get an async postback if I then click the 'Cancel' button for that GridView row which appears after having clicked the 'Edit' button.
However, if I instead click the 'Update' button that appears after having clicked the 'Edit' button, I get a full postback. I have tried almost every GridView EventName
I can find to add to the <Triggers></Triggers> section to get a click of the 'Update' button to result in an async postback, but with no luck.
What EventName should I use in the <Triggers></Triggers> section to get a GridView to do an async postback when clicking the 'Update' button for a particular row?

I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.
How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?

How do I stop a TEXTBOX from rending on user click?
I have a gridview, a button, a textbox (for searching string) on my web page. When the button is clicked the data is exported from the gridview to MS EXCEL. I am having issues with the following code. It execute the export to MS Excel when the user click the enter key.
NOTE: My application works fine except for when the user clicks the enter key on the keyboard the export seems to be triggered. I do not want that to happen on enter.
CODE:
Public Overloads Overrides Sub VerifyRenderingInServerForm(ByVal control As Control)
'Confirms that an HtmlForm control is rendered for the specified ASP.NET server control at run time.
End Sub
GOAL: How do I specify only the Gridview control to be rendered, when the above function is called.
Only gridview control when the button is click. No other user activity should execute the the MS Excel export. I would like to exclude textbox control from VerifyRenderingInServerForm?

I've been trying to exclude an asp.net web control from the tabbing order.The control that i'm using is the RadioButtonList control. I've try setting the TabIndex to either 0 or -1.The problem that i'm running into is ... initially the control is skipped (which is good), but it seemed like the engine just shifted the control to the end of the tabbing order. Is this an expected behavior? or is there a work around for this?
After checking the HTML source, I have some interesting findings ...
<td><input id="rbSpiffType_0" type="radio" name="rbSpiffType" value="R" checked="checked" tabindex="-1" /><label for="rbSpiffType_0">Regular Spiff</label></td><td>
I think i might be tabbing into the label .
