Code behind:

{
protected int menuID;
protected void Page_Load(object sender, EventArgs e)
{
string menuIDdata = Page.Request.QueryString["mid"];
menuID = 0;
// Check the user is allowed here
if (!Roles.IsUserInRole("Admin"))
{
Response.Redirect("../default.aspx");
}
// Get the menu ID
if (int.TryParse(menuIDdata, out menuID))
{
menuID = int.Parse(menuIDdata);
}
else
{
menuID = 0;
}
mnu0.CssClass = "navButtonO";
}
}
I'm trying to change the class of the menu depending on which one is selected, but is there an elegant way to change the class instead of a switch/if statement? For example:
mnu[menuID].CssClass = "navButtonO";
Would change the class of the menu item.

am fairly new to AJAX, but have successfully got my page working in FF and somewhat working in Opera and Chrome.I have made a table, and populated cells of that table with an AJAX call to a sever side script.I am then using those cells in mathematical equations on the client side.In FireFox this works smoothly, In IE it fails completely. IE doesn't see that there is a value to the cell of the table, even though it displays the information in the cell after the AJAX call. Am I doing something wrong to make IE over look the fact that i have changed the DOM? or am I doing something completely impossible in IE?I need a way to let IE know that there is a value in the cell.

I have a webform that accepts a date range to generate PDF reports. I had to place a PostBackTrigger on the updatepanel and assign the button thaat generates the reports because the Response.ContentType is being set to "application/pdf".
The problem is I am updating the textbox value to the count of clients that are left out of the report generation in server side code, the count always come back as 0. I have tried multiple panels with no luck. The textbox is in the main updatepanel with the print button and that still does not work.

Strange problem with CalendarExtender
[Code]....
The text box is updated correctly if it is empty or if the date is invalid e.g. 9/292010.
If the current text is 9/29/2010 and a different date is clicked then the calendar stays open with the previous date selected. I get the following error message "e.getDateOnly is not a function".

I have an ASP.NET AJAX application, which is using .NET Framework 3.5. I have visual Studio 2008 installed on my developer machine. The AjaxControlToolKit dlls I have installed in my system right now come from the file "AspNetAjaxLibraryBeta0911.zip". The released date of the dlls in the file is 12/29/2009. Exploring the AjaxControlToolKit download site, I found that there is a more updated version, which release date was April 12th 2010.
I tried to update the AjaxControlKit.dll version to the newest one. I did this creating a path in my system: c:Program FilesAjaxControlToolKitWebFormsRelease then I placed there the new AjaxControlToolKit.dll and AjaxControlToolKit.pdb files. Then I right clicked on the name of the dll inside my Bin directory in my application and selected "Update Reference". After I did this I tested the application and is giving me Jscript error messages like: "htmlfile: member not found", or Microsoft Jscript Runtime error "lenth is null or not an object". I don't get these error messages if I come back to the previous version of the AjaxControlToolKit.

I have UpdatePanel1 inside of which I have a Server Side Call Button - BT_ServerCall.
Then I have a second UpdatePanel2 which has a listbox (populated in pageload with some items) , a label, a hidden field, and a Button which calls a javascript function BT_JSCall.
Finally there is a second listbox which does not reside in an updatepanel.
i am populating the second listbox with values selected in the first listbox. then I click the BT_JSCall button which calls the javascript function copy_to_hidden_field() , inside which I take the values from the second listbox and store them as a concatenated string in the hidden field. Lastly, in the javascript function I simulate a button click event on BT_ServerCall. At this point I hit the server side method for the click event and I extract the value from the hidden field. lastly I change the value of the hidden field and also copy the new value to the label. I call the updatepanel2 update method (both updatepanels are set to updatemode conditional).
here is the problem: neither the hidden field nor the label get updated with the new text.
here is code
aspx.cs:
public partial class WebForm3 : System.Web.UI.Page

I have a long running asynchronous process which returns a total of around 10-100 results over a 5 minute period. I want to update the page with the progress of the job and also show each result on the page in a list that grows dynamically as results are returned, all without any postback or page refresh.

I have a page with 2 update panels.
Controls in the update panel holds a listview and each row here has a button. This button fires a FancyBox (modal dialog) When closing this a call to the onClosed event is triggered like here:
[Code]....
There is two of these sections one for each update panel. The problem here is that this 'Page.ClientScript.GetPostBackEventReference' actually updates the wrong update panel!It is always updating the first updatepanel on the page, and I cannot figure out why this is. The two update panels areencapsulated in its own user control, but still the first update panel is always fired.

I have a web form for payments which consists of a DropDownList (credit card, purchase order, bill me). By default, credit card is selected, and the form (a ListView within a UpdatePanel) is loaded with the user's billing address. If the user changes the payment option, the form fields change -- for example, if purchase order is selected, the billing address + credit card fields disappear and a "Purchase Order Number" textbox appears. This is done using an AsyncPostBackTrigger associated with an event in the DropDownList.My problem is that when the form is submitted, I cannot see the user-entered values within the UpdatePanel/ListView, but I can see the original values loaded in the ListView before the edits were made. For example, if purchase order is selected, I can see the billing address from the ListView, but I cannot see the newly-entered Purchase Order Number from the ListView.Here's an abbreviated version of my code. I've bolded and commented two lines where the problem appears:

I have a webpage with multiple updatepanels on. One of the panels takes a long time to load. I therefore start a timer on page load and the timer.tick event populates the accordion control within the panel. Because of the amount of data I have used a paged data source and have link buttons to scroll through the results.
I need to implement animation, both on the initial page load and each time the button is clicked to move through the pages. The animation is, show a loading icon and hide the accordion/grid, once the data is loaded, display the accordion/grid and hide the loading icon. I have tried both the PageRequestManager and AnimationExtender, which I fail to get working for both the initial page load and Updating/Updated events.

I want to trigger two Async Postbacks at once using UpdatePanel's via their associated buttons such as the example at the end of [URL] When you click the first button, then immediately click the second button, the first button's message never gets updated. By clicking the second button, the first async Post back seems to be cancelled. Why does this happen?
I saw this article about only allowing one postback to occur at a time here: [URL] Is this the desired behavior for Multiple update panels? Can only one run async code at once? What's the point of it being async if you can't do multiple at once? Here's what I'm trying to do overall: I want a webpage where I click a button which causes C# code to search a certain webpage and parse it. Based on the parsed information, it should automatically start searching multiple other webpages. All the while, I want the web UI to be updated with the progress.
Button Press and the client UI says "Searching..." Then the webpage is found so I want to display "Parsing..." Then the webpage parsing is complete and multiple other websites are searched at the same so the UI will display:
Webpage 1 updating...
Webpage 2 updating...
Webpage 3 updating...
Then when the Webpage 1 -3 are done updating, they change their progress message to Complete. I just started looking into ASP a few days ago and I have two ideas how to approach this problem: zy first idea was to use UpdatePanels and UpdateProgress because they seemed easy to get in there. However, the part of updating multiple webpage status messages at once doesn't appear to be possible since I can't have two UpdatePanels updating at the same time to make changes to the client UI. The one that is started second takes over the processing and the client UI isn't refreshed until that second asynch postback is complete. Ideally, there would be a way to refresh the UpdatePanel's mid postback............

For my project, i have decided to use AjaxControlToolkit's ModalPopup controls. I have obtains codes from this website: [URL] After following all the steps provided by Matt, I am getting some problems when i want to save my edited information. Scenario 1: Select the first item from the gridview, modify the details at the details view and click save, gridview updates and shows the edited information and it is stored into the database.
Scenario 2: Select the second item onwards from the gridview, modify the details at the details view and click save, screen remains at detailsview and edited information is not saved, click cancel button to return to gridview, data at the gridview was not updated. So basically, the update function works only for the first item from the gridview. The following is parts of my code:
<%-- Display list of Activities according to the Project--%>
<asp:UpdatePanel ID="UP_ActList" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="GV_ActList" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDS_ActList" DataKeyNames="dbID"
OnSelectedIndexChanged="GV_ActList_SelectedIndexChanged">

<Columns>
<asp:BoundField DataField="dbID" HeaderText="dbID" Visible="false"
SortExpression="dbID" ReadOnly="true" InsertVisible="False" />
<asp:BoundField DataField="ActID" HeaderText="ActID"
SortExpression="ActID" />
.......Other BoundField were deleted for this post purpose............

<asp:LinkButton ID="LinkB_ViewActDetails" runat="server"
Text="Edit" CommandName="Select" CausesValidation="false"></asp:LinkButton>
