However, when I try to build the control I'm getting the error as shown in the subject. I've tried searching, and it seems the signature for the original function matches the one I have, and all other solutions I've seen uses the same signature.

How to use Generic collection and generic list effectively in a asp.net application i.e. web application.? Can we able to use Generic list in Dataset or Datatable or Datareader using to bind in Grid view?

At debug time I would like to see what are the keys in my InitParams collection - I can't seem to be able to list them.
EDIT:As Jon suggests below, this might be a bug within the Silverlight debugger. To reproduce, just create a new Silverlight Application within Visual Studio 2010 and just edit code

I am using datalist to bind the generic list. On databind() command I am getting error "nable to evaluate expression because the code is optimized or a native frame is on top of the call stack.
I was building an application for a project with .NET 3.5 and I noticed a weird behaviour of the List.Add method:
I have built my own class to organize data pulled from a database, and I use a while cycle to iterate through it.
However, when I List.Add(item), the whole content of the list is substituted with the last content pulled.
An example:
Suppose you have 3 users in a DB, each one identified with an ID and a username:
| ID | username | | 1 | John | | 2 | Fred | | 3 | Paul |
and you have a "Users" class defined as
public class Users { private Int32 iD; private String username; public Int32 ID { get { return iD; } set { iD = value; } } public String Username { get { return username; } set { username = value; } } }
So you write this function:
[... SQL definitions - sdr is a SqlDataReader ...] List<Users> userlist = new List<Users>(); if (sdr.HasRows) //There are users { Users user = new Users(); while (sdr.Read()) { user.ID = sdr.GetInt32(0); user.username = sdr.GetString(1); userlist.Add(user); } }
What you expect (I expect) is userlist containing:
| ID | username | | 1 | John | | 2 | Fred | | 3 | Paul |
What I actually get is, instead
| ID | username | | 3 | Paul | | 3 | Paul | | 3 | Paul |

I'm trying to do a simple update to product names in the product table based on the manufacturer ID
In order to do this I am looping through each record. I was initally successful with changing all names in the column but when I try to query the data, I continually run into multiple problems.
The following poster has had the same issue I have but his solution isn't working for me.

I keep getting the same error on the opening bracket on the select statement in the SelectByManufacturerID function...
Error 1 Cannot initialize type 'DataBaseDataManagement.ProductName' with a collection initializer because it does not implement 'System.Collections.IEnumerable'
Button that does the actual updating...

I have a problem i just cant get around...I'm trying to sort the contents of a gridview that gets filled from a List<T>.
(working in DAL, BLL & Presentation layers).
The Gridview's source code:
[code]....
What i cant figure out is how to implement the sort method to the gridview when fetching data from a generic list... I have been Googling my a** of trying to solve this.
I have a generic list of a custom type. The custom type has a string and double.I'm binding the list to a gridview and it outputs everything fine.I'm trying to format the double column into a currency format. It is in a template field as I'm calculating a running total. I pass the value to a function that returns a double and adds the current value to a running total which I will show in the footer.
The format is not changing to currency as expected when using String.Format("{0:c}", GetTotal(Convert.ToDouble(Eval("Amount"))))
