Mvc File Upload Is Passed As Null To View Model?
Aug 19, 2010I have a form which uploads a photo to my database, and I use a view model to aid in this process.
View Model:
public class GalleryViewModel
{
//Members:
public Gallery _photo { get; set; }
public string _title { get; set; }[code]...
When I debug the code, I see that the in the post method in my controller, all the information from the form is updated in the view model except for the uploadFile which is null.In the form I use enctype = "multipart/form-data". When I use my master page the uploadFile is null but when I use the default MVC master page everything works fine.
Here is my master page:

Web Forms :: Radio Buttons In User Control With Complicated Layout?
Mar 8, 2011I have a user control I'm building that has a table layout with two sets of radio buttons, like:
how I could use a radiobuttonlist for each set of vertical buttons within this layout, unless I used a rowspan on each col, but that seems problematic from a layout perspective? I would rather use a RBL from a programming standpoint.
If I instead used a set of radiobuttons with a groupname for each, how do I get/set the selected button (for each set) from outside the UC?
Localization :: Making RESX Translation Process Less Complicated / Time Consuming
Dec 27, 2010I have worked on many localized sites in the past, using mainy some standard patterns and techniques involving Global/Local RESX files as well as session to maintain currently selected language.
However, it is quite difficult to maintain from a translator point of view, we used a small tool that converts RESX to Excel and then the localized Excel back to RESX, but for some reason this technique doesnt work properly anymore...
better and more reliable tools (paid or free) that can be used to localize RESX and provide translation team a better/easier way to localize content?

View 4 RepliesC# - Using A Variable From A Foreach Loop?
Dec 6, 2010i'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();

C# - Foreach Not Initialing The Loop Variable?
Mar 9, 2010I'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.
C# - Passing In A Value To A Usercontrol Through A Foreach Loop?
Dec 21, 2010in 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.

ADO.NET :: Copy Datarow Content Without Foreach
Jan 12, 2011 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";

C#: Adding Context To Parallel.ForEach()?
Sep 24, 2010I 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().

DataSource Controls :: LINQ To SQL - Foreach - To CSV?
Jun 11, 2010I'm close to the solution I see where I am going wrong just unsure how to approach it. I want to be able to take a tables worth of data (via DataClasses) and put it in a CSV to download.
A LINQ to SQL query is performed (basically a 'Select All' from tbl_Newsletter), takes those results and the idea is to feed those results, one by one through the foreach which, inside it, is the CSV's definition e.g. List.Add(etc) as you'll see. After which the CSVExporter method is called - which works, as I can Download it, it just wont display any results.
C#: [Code]....
To which I get: Compiler Error Message: CS1729: 'Newsletter' does not contain a constructor that takes '2' arguments
with Newsletter obj = Newsletter.GetAll(); in place of Newsletter obj = new Newsletter();
I get: Compiler Error Message: CS0029: Cannot implicitly convert type 'System.Collections.Generic.List<Newsletter>' to 'Newsletter'
