C# - 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.

View 4 RepliesMVC :: Ajax.beginform Inside A For Loop?
Oct 2, 2010so I am using a foreach loop to iterate through comments. The comment section is wrapped inside "Comments" div. My function **DeleteComment** fetches comments again once you delete a comment and rebinds it to the control. However, after you delete a comment, anytime you try to delete another comment, the commentId of the very first deleted comment would keep getting passed to **DeleteComment** function instead of the passing the commentId of the comment you are trying to delete. If you refresh the page, then you can delete ONE comment again, and the same problem if you try to delete another.
