using an anonymous function for an action result

Posted By:      Posted Date: October 14, 2010    Points: 0   Category :ASP.Net

i can assign a simple anonymous function and it works, but i'm having trouble with a more complex one.

i am attempting to disable an image button after it is pressed.

any alternatives would be welcome, but i think this is the recommended

            <% var options = new AjaxOptions{ 
                  HttpMethod = "POST", 
                  UpdateTargetId = "lblAdded" + product.ProductId,
                   //OnComplete= "function() {alert('dddd');}",     <-- works
                  OnComplete = "function() {(document.getElementById('ibtn" + product.ProductId + "')).disabled='disabled';}" <-- does not work
            using (Ajax.BeginForm("AddToCart", new { id = product.ProductId }, options))
           { %>

 way to do it(?)

301 Redirect as a Action Result

 I just wonder what you think it the "proper" way to perform a 301 Redirect from a Controller? I can NOT set up Routes in Global.asax because the URL comes from a database. My current approach is this:         [HandleError]        public ActionResult Resolve(string id)        {            if (string.IsNullOrEmpty(id))            {                return RedirectToAction("Index", "Home");            }            else            {                string url = DatabaseFunctions.RetreiveUrl(id);                if (url == null)                {                    return RedirectToActio

Aggregate (count) function that produces a different result to what is expected.

Hi Folks
I have an aggregate transformation, that runs a count on a column.  The  column  has 23 rows  with dates and a further 2 rows that have no date information. When I run a count function on the column, it returns a count of 25.  My hypothesis is that  this is linked to the 2 rows are treated as being  BLANK as opposed to being NULL (I understand the COUNT function will not count rows that have null values).

I have two questions
1) How do test this hypothesis that he difference is due to a blank vs null issue and then more importantly
2) How to I resolve the issue so that the 2 "empty" rows are not counted?

Many thanks


Tuples, Anonymous Types, and Concrete Types

Tuples can save you a great deal of repetitive tasks. They can also lead to completely unreadable code in a language like C#. Tuples are data values that contain N items. The .NET framework supports tuples containing 1 to 8 members. To use tuples with more than 8 members, you use another tuple for the member of an octtuple

connection to SQL Server files (*.mdf) require SQL server express 2005 to function properly.


I dont have the SQL EXPRESS installed instead I have SQL Standard Edition.

 I have two SQL Server instances installed.

 1- UserLT (this is sql 2000)
2- UserLT\SQL2005 (this is SQL 2005 named instance)

But when i try to add a database to my VS website project I get the following error:

Connection to SQL Server files (*.mdf) require SQL server express 2005 to function properly. please verify the installation of the component or download from the URL: go.microsoft.com/fwlink/?linkId=4925

I went in Tools>Opetions>DataBase tools>Data Connection>Sql Server Instance Name (blank for default)

and changed the "SQLEXPRESS" to "USERLT\SQL2005".

But I still get the same error message. Any ideas how i can resolve this issue?

Public Shared function doubt????

I am using VB.net/ASP.NET and SQL Server 2000 for a web application.

For populating the dropdowns, I wrote a Public Shared function LoadDDL(), in which I pass the dataset and dropdown name to set.

I have my doubts that this function will produce unexpected results for concurrent users. And will mix the results among sessions because it is a Shared function.

I am confused here. Is it the right way to go?

Please advice. Thanks in advance.


Active Directory and .NET: paging the search result

Hi everybody!

I have a question about Active Directory in .NET
For my project I need to fetch results from Active Directory search page by page, because later I would need to bind it to the pageable DataGrid.

I tried to use .NET library DirectoryServices for that, but paging provided by this library is transparent to the user and is used only to increase the efficiency of searching, when results are too big. I.e. I cannot tell the DirectorySearcher to give me first page, then the next or previous page, it returns me all resulting pages in one bundle.

However, what I need is to explicitely get page after page directly from the AD searcher and to be able to go at least one page forward or backward.

The solution with copying all results to the DataBase and then do the paging is not accepeted by the clent, since it is too inefficient. And since it's a Web app, I cannot keep results in memory either.

I found some hints about COM Interface, but I could not find good and detailed examples or explanations. I aslo found this line of code: DirectoryServices.Interop.IDirectorySearch.ExecuteSearch(), but I don't know which libraries should i add to be able to compile this code.

If somebody could help me out with that problem, any suggestion is welcome, 'cause this issue is eating me alive :)

Thank you!

As I promised last time, in this month's column I'll walk through the process of defining and invoking a generic or template function under C++\CLI. A function template or a generic function begins with the template or generic keyword followed by its parameter list.
