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 have a project that it had been developed under MVC1 and after aa few months ago I upgraded it in MVC2.
Everything was well, uppon the day I needed to format my computer.
And what can goes wrong with a format? I don't know
I have installed the MVC2, I build the project, no error displayed, but from the time I've uploaded the project in the production server
I am getting this error.
Method not found: 'System.Web.Mvc.MvcHtmlString System.Web.Mvc.Html.LinkExtensions.RouteLink(System.Web.Mvc.HtmlHelper, System.String, System.Object)'.
I can't understand what caused the problem.
Certainly I assumed that is have to do with MVC1 and I referenced it, but with no luck
again.
Theese are the methods that the problem is came from

We have a Page Method on a web page using ASP .Net. We tried to put in a trace statement using both System.Diagnostics and System.Diagnostics.Debug. In Visual Studio 2008, the break point is not even hit for the line, but other break points on other lines are hit.There is no output from either method that we can see.
There is also a Global.asax error catcher that works fine in other cases, but in the Page Method is not being catched.why a Page Method and System.Diagnostics do not play well together?
How can I create generic class from System.Web.Mvc.ViewPage?
View 1 RepliesI have a few web applications that I maintain and I find myself very often writing the same block of code over and over again to bind a GridView to a data source. I'm trying to create a Generic method to handle data binding but I'm having trouble getting it to work with Repeaters and DataLists.
Here is the Generic method I have so far:
[code]....
That way I can just define my CommandText then make a call to "BindControls(myGridView, cmd)" instead of retyping this same basic block of code every time I need to bind a grid.
The problem is, this doesn't work with Repeaters or DataLists. Each of these controls inherit their respective "DataSource" and "DataBind" methods from different classes. Someone on another forum that I implement an interface, but I'm not sure how to make that work either.
The GridView, Datalist and Repeater get their respective "DataBind" methods from BaseDataBoundControl, BaseDataList, and Repeater classes. How would I go about creating a single interface to tie them all together? Or am I better off just using 3 overloads for this method?
I have this ASP.NET code:
<asp:DropDownList
ID="ddlBrokers"
runat="server"
AutoPostBack="true"
DataSourceID="srcBrokers"
DataTextField="broker"
DataValueField="brokerId"
/>
<asp:ObjectDataSource
id="srcBrokers"
TypeName="DatabaseComponent.DBUtil"
SelectMethod="GetBrokers"
runat="server">
</asp:ObjectDataSource>
My DAL code:
public DataTable GetBrokers(bool? hasImport=null)
{
SqlCommand cmd = new SqlCommand("usp_GetBrokers");
if (hasImport.HasValue)
cmd.Parameters.AddWithValue("@hasImport", hasImport);
return FillDataTable(cmd, "brokers");
}
When the form loads I get this error:
ObjectDataSource 'srcBrokers' could not find a non-generic method 'GetBrokers' that has no parameters.
Is it my optional parameter that is causing the problem? How can I workaround this? Is it possible to have optional parameters with declarative ASP.NET code?

I'm a starting C# programmer and I'm experiencing the following problem.I've created a dataset in Visual Studio With a table for persons making use of two table adapters, one for selecting all persons and one for selecting one person at a time filtered by the personID (Guid). This is a seperate project of my solution. After that I created a new project for the Business Logic Layer
private PersonenTableAdapter personenAdapter = null;
protected PersonenTableAdapter Adapter
{get....}
[System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, true)]
public DAL.Testdatabase.PersonenDataTable GetPersonen()
{...}

public DAL.Testdatabase.PersonenDataTable GetPersonenByID(Guid ID)
{...}

public bool updatePersoon(string Voornaam, string Achternaam, string Geslacht, string Adres, string Huisnr, string Postcode, string Plaats, string Telnr, string GSM, string BSN, DateTime? CreateDate, string CreatedBy, DateTime? LastModifiedDate, string LastModifiedBy, bool? Actief, DateTime? DatumInactief, Guid ID)
{...}
When issueing the Update method using a detailsview with an Objectdatasource i get the following error.
ObjectDataSource 'ObjectDataSource1' could not find a non-generic method 'updatePersoon' that has parameters: Voornaam, Achternaam, Geslacht, Adres, HuisNr, Postcode, Plaats, Telnr, GSM, BSN, CreateDate, CreatedBy, LastModifiedDate, LastModifiedBy, Actief, DatumInactief, original_ID.

{
Guid UserId = Guid.NewGuid();
int rowsAffected = Adapter.Delete(ID,UserId);
// Return true if precisely one row was deleted, otherwise false

The problem is when I use Guid UserId = Guid.NewGuid ();.
In Table I UserId type: unique Therefore it does not work. If I use the UserId type: int working.

In one of the methods I'm using in my MVC app, there's a param that accepts a list collection of strings. If I have a string parameter, I can give it a default value of an empty string, but I cannot seem to give the list collection a default value of a new, empty list collection. I get the error that's beginning to seriously grate on my nerves about requiring a compile-time constant. getting the generic list to work with a default empty set?
View 5 RepliesI 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 am getting error : ObjectDataSource 'ObjectDataSource1' could not find a non-generic method What would be the possible cause / solution for this error.This error is coming when call below method ObjectDataSource1.SelectMethod = "MethodName"// thr r some more code after that, although not much irrelevant
en call Server.Transfer("NewPage.aspx", True);
I added the extender and when i tried to add the method this message poped up; Cannot create page method "GetCompletionList" because no Code Behind or codefile was found.
