What am I missing here. I just want to pull the first one returned from row.detail in an MVC2 view, how would i do this without a foreach loop? This code currently works, but i just want the first one listed. I know this may be simple, but i am drawing a blank.
if (Model.App != null)
{
foreach (var row in Model.App.Instructions)
{
<input type="hidden" value="<%= row.Detail %>" id="ixd" />
}
}
How can I call a URL ex.

Provided wsdl from link below:
http://www.2shared.com/file/zfTUDRl3/poccrm.html
I've been given merely a wsdl above from client, without any further information given, to make a call using c# code but i added as web reference, used the codes below and the client side detected my request and they've returned us proper format xml too, but i cant retrieve it in the string array from the method returned. the "stringset" has became null instead of array[10]. Can anyone give a hint what kind of web service call is it, since it is not using the simple and classic way to invoke?
static void Main(string[] args)
{
//added web reference for wsdl as poccrm
string[] stringset = new string[10];
poccrm.poclib caller = new ConsoleApplication1.poccrm.poclib();
poccrm.SE1I2001 callerItem = new poccrm.SE1I2001();
callerItem.AcctNo = "0010241000007914";
callerItem.TransNo = "12345678901234567890";
callerItem.StartDate = "20-01-2010";
stringset = caller.SE1I2001(callerItem); //here i get null for stringset, but client received the request and returned us value
//same result even I use wsdl.exe converted it to a class file
/*
string[] stringset = new string[10];
poclib caller = new poclib();
SU1I1001 callerItem = new SU1I1001();
callerItem.AcctNo = "0010029004000370";
callerItem.transno = "12345678901234567890";
caller.end
stringset = caller.SU1I1001(callerItem);
*/

I have the following javascript:
$.post("/Authenticated/DeletePage/" + PageId);
showStatus("Page deleted...", 10000);
I would like to instead pass showStatus() text that is returned by the $.post() call, rather than hardcoded text. How do I do this?

I am developing a web dashboard under a deadline. We are interested in making a demo release before the dashboard has been fully developed. It does not currently have the concept of a logged in user.
The state of the web dashboard is currently saved into Session. All my classes are serializable, and I was able to set my SessionState Mode to SQL Server and write Session to a SQL Database. I would be able to use this to serve my purposes, but I have been unable to figure out how, if possible.
The goal is this: "Represent the saved state of the web dashboard as text and be able to load the state of the dashboard on another computer." The method to me was to write XML to a text file and be able to move that text file to another computer, point at it, and load my state again.
My issue with writing Session State to a SQL Server is that when the Session expires (browser closed/time out) I am unable to load the old data up onto the page. If there was a way to say "Take the data from session state _ and load it onto the page" I would be golden. As far as I can tell this isn't possible.

I have a ASPxGridView. In it(for the uninformed) is only a DataSource property for telling it what data to load. My problem is that I'm simply trying to mock up an example and don't need to tie it to an actual database. How would I do this? I basically just want a few rows and some columns but since it only takes a datasource I'm not sure how to do it. Would ObjectDataSource be what I'm looking for?

I have one ASP.Net web page dynamically loading any one of about twenty User Controls at a given time. Since each user control is somewhat different, I've implemented the following extension to me pass a variable number of parameters to custom user control constructors: [URL]It, by the way, works very well! However, I've now come across the fact that both the web page and the user controls will need to share a few Data Tables. In other words, both the web page and the user control will need to access and manipulate data in these data tables.
To implement this fact I've used the Session object to store each data table. Each of these data tables starts out empty and then starts growing as the user enters more data into the user controls. The initialization of the data tables has to be done in the web page for a series of technical reasons that I won't get into here but rest assured that it does have to occur there.
But I found that in order to ENSURE that the initialization was taking place, it was simplest to just pass a reference to each data table as an extra parameter in the LoadUserControl call. This does work but it seems like overkill to me because on the user control constructor side, nothing is actually done with the data tables at the time of instantiation of the user control.
This made me go back to basics, thinking, "Why include a parameter if you're not actually going to use it?" But yet, it does seem to be the most straightforward way to ensure the data table is initialized and stored in the Session object.
I am using Visual Studio 2010 and therefore have RDLC 2010 so developed couple of reports but when I run the project within developer machine and tries to export in Excel it works fine. But when I deploy my project on UAT machine (IIS) it simply refuses to export with the following error"The file you are trying to open 'myreport[1].xls' is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file."then it ask do u want to open anyway...when you select YES then it comes simply blank.

I have two update panels and in the second update panel i have asp.net button and onclick of the button in codebehind i have disabled it like btnAddSecurity.Enabled = false;
When I disable the button i enable a cancel button before it and on cancel button when i try to enable the btnAddSecurity.Enabled = true it simply doesn't work. Both of my updatepanels updatemode is conditional. what is the problem?
i'd like to be able to check to see if an item with the same id has already been placed in the database, if so to then update the quantity for that item, however due to the fact I have this in a foreach loop it will update the quantity for each item.
When I placed the Command outside of the loop I am unable to use 'ItemID' as it's not in context, is there anyway I can get around this?
foreach (UserItem ItemID in (List<UserItem>)Session["UserSession"])
{
ConclusionPage.InsertCommand = "IF EXISTS (SELECT ItemID FROM tblUserItems WHERE UserID='@CurrentUser' AND ItemID='@ItemID') UPDATE tblUserItems SET Quantity = Quantity+1 WHERE (UserID = '@CurrentUser') AND (ItemID = '@ItemID')";
ConclusionPage.Insert();
}
I'm using a foreach to loop through an IList of objects in a Partial View in ASP.NET MVC.
Here's the entire code (Message is one of my classes from the Model).
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IList<Message>>" %>
<%
if (ViewData.Model.Count > 0)
{
foreach (MvcTest.Models.Message m in ViewData.Model)
{
Response.Write(m.RenderHtml());
}
}
ie explicitly declaring a variable for the IList rather than just using the (strongly-typed) Model, and it works fine.
in my asp.net mark up I have a foreach loop that iterates through a simple list. In this foreach loop I am adding a new user control and attempting to pass in the value from the loop. However, this value just wont budge and get inside that damn control!
<%foreach (userInfo i in this.items)
{ %>
<uc1:ItemControl ID="ItemControl" runat="server" UserID='<%#Eval("userID") %>'/>
<%} %>
userID is a public property in the control, when it goes to set, the value is just literally :
<%#Eval("userID") %>. I've tried #Bind and =Value but nothing seems to work.

have 5 datatables and will add up more, what i need is to copy the content(rows) of the each and every datatable in a separate datatable. All the datatable columns are same. Is that possible without foreach statements. We can achieve the results in foreach
but the datatables will contain more rows, so iterating each and every datatable will affect the performance.he code i implemented is exact thing i need, but without foreach statement. To copy content of each and every datatable and put the content in a final datatable
DataTable dat = new DataTable();
DataRow Dr = dat.NewRow();
dat.Columns.Add("c1", typeof(string));
Dr[0] = "01";

My code for splitting the strings is working however, i still need to use the splitted string my page. How can i achieve this? Here's my current code
private void SplitStrings()
{
List<string> listvalues = new List<string>();
listvalues = (List<string>)Session["mylist"];[code].....
how can i replace the response.write with any label or literal? when i tried to use a literal on the code it displays one single string not all of the strings that's been splitted.
I have a static class with a static get property, and in this property, I do this:
// property body
{
// HttpContext.Current is NOT null
Parallel.ForEach(files, file =>
{
// HttpContext.Current is null
var promo = new Promotion();
});
// HttpContext.Current is NOT null
}
This static class doesn't undergone type initialization until a view uses this property.
The problem is that Promotion's static constructor, which is initialized the first time a new Promotion() is created within the Parallel.ForEach(), uses HttpContext.Current. When promo is instantiated within the scope of this Parallel.ForEach(), HttpContext.Current is null, and new Promotion() therefore causes an exception.
HttpContext.Current is not null within the static get property because it's not called until the view uses it (and there is therefore a HttpContext.Current).
If Promotion used HttpContext.Current in its instances instead of its static members, I could probably just pass HttpContext.Current into the new Promotion() constructor:
var context = HttpContext.Current;
Parallel.ForEach(files, file =>
{
var promo = new Promotion(context);
});
But since static members of Promotion need HttpContext.Current, I can't. I could probably redesign the Promotion class to change the static members that need it to be instance members, but they are static for a reason--there would be a large performance penalty if all the members that were static had to be defined instead on each instance each time a new Promotion was instantiated.
What are the possible workarounds for this? I didn't realize HttpContext.Current would be null within the scope of Parallel.ForEach().
