Security :: Way To Create Tables That Uses Duplicate Entries?
Apr 17, 2010I am using the built in database with the tables (i.e. membership, users, etc...). I created my own table (relationships), but when I try to create a row that uses the same email address it says "cannot create duplicate entries". I am not allowing duplicate email addresses in the membership table. That did not work because I couldn't convert System.Guid to long. So, I decided to do it by email address. I changed idRequester to requesteremail and the same for receiver. However, when I try another record with the same email address in either field, it does not accept it.
View 1 RepliesEntries In The Host File Create New SessionIDs For Each Request?
Nov 19, 2010I am working on an update to one of our sites. This version will have unique behaviors based on the host name in the request. In order to test this behavior, I modified my computers host file by adding entries that point back to my computer.
127.0.0.1 newhostname.sample.com
127.0.0.1 oldhostname.sample.com
Everything seemed to be working fine, until I started working with the Session object. I discovered that after each request all my session variables were lost. Further investigation revealed that each response from the server contained a new SessionID.Why is that?I was able to hard code some flags to complete my testing using 'localhost' for requests without any problems.
Web Forms :: Loop Through Database Entries And Create Text Box For Each One?
Jul 14, 2010I am currently working on a project where I am trying pull a list of entries from an Oracle database depending on a selection that is made by the user via a Drop Down list. Then I want provide a user with a list of options that they can select that is related to the drop down option that they have selected. For Example:
First Drop Down from database: Honda, BMW, Ford
If user selects:
Honda -- options that are available in the separte table in the database for this entry are -- Type, Engine Size, Colour
BMW -- options that are available in the separte table in the database for this entry are -- Colour, Wheel Trims, Extra's
Ford -- options that are available in the separte table in the database for this entry are -- Extra's
What I wanted to do is have a form displayed to the user where thy can say select a car eg. "BMW" and then on the change of that drop downs index the site will do a call back and retrieve the entries for the BMW options in the seperate tabel, these being Colour, Wheel Trims, Extra's. Then it will put these details in a DataSet and then i wanted to create a new text box or input field for the users to enter details in. I have tried the below code with no success as I get an error on my for loop of looking through the options DataSet.

SQL Server :: Select - Multiple Dropdown Lists To Only Include Table1 Entries
Aug 1, 2010I am trying to get the drop down list to only include table1 entries where table3.int1 is the current selection in another drop down list (table2.id). Example:
Table1: id, string1, int
Table2: id, string1, string2, dec

AJAX :: Countdown Timer Counts Double?

View 6 RepliesWhat's The Official Microsoft Way To Track Counts Of Dynamic Controls To Be Reconstructed Upon Postback
Dec 21, 2010When creating dynamic controls based on a data source of arbitrary and changing size, what is the official way to track exactly how many controls need to be rebuilt into the page's control collection after a Postback operation (i.e. on the server side during the ASP.NET page event lifecycle) specifically the point at which dynamic controls are supposed to be rebuilt? Where is the arity stored for retrieval and reconstruction usage?
By "official" I mean the Microsoft way of doing it. There exist hacks like Session storage, etc but I want to know the bonafide or at least Microsoft-recommended way. I've been unable to find a documentation page stating this information. Usually code samples work with a set of dynamic controls of known numbers. It's as if doing otherwise would be tougher.
Update: I'm not inquiring about user controls or static expression of declarative controls, but instead about dynamically injecting controls completely from code-behind, whether they be mine, 3rd-party or built-in ASP.NET controls.
Forms Data Controls :: Trying To Add A Label In Gridview That Counts The Number Of Records?
Aug 18, 2010I am trying to add a label in my gridview that counts the number of records that are being displayed as well as the total number of records found via the datasource. and i want this label to be displayed in the pager template of the gridview i.e. at the bottom.
I have the following code:
[Code]....
which i run in the rowdatabound method of the gridview. but when i run it it comes up with an error saying "null reference exception handles by code".i think the error lies in not being able to count the total number of rows in the sqldatasource in the int variable intTotalRecords. How do i go about counting the number of rows in the datasource that i am trying to pass in?

AJAX :: Textbox Does Not Remember Entries?
May 3, 2010I am using the TextBoxWatermark extender ASP.NET AJAX extender this works great, but i still want to have the comfort for my users, that the textbox remembers their entries e.g.:
Login=> TextBox with UserName
- if two people are using the same computer, they don't want to type UserName each time again instead click in the box and choose their UserName or start typing and their UserName is than suggested.
It seems to be a standard funktion that a TextBox remembers the entries you did. Unforantly when using the watermark extender on a textbox it simply does not work anymore.
Is there a way to enable this „feature" again?
When looking at the example of the TextBoxWatermark ASP.NET AJAX extender: [URL] it is not working their as well.

MVC :: Submitting Multiple Data Entries?
May 24, 2010I am wondering how to handle and setup a means to submit multiple data entries via ASP.NET MVC.
Suppose I have a product database table such as: ProductId, ProductTitle, Price.
From the view, I was thinking to code the HTML form as:
<form ... >
<table>
<tr>
<th>ProductId</th>
<th>ProductTitle</th>.......
Suppose the form is to be submitted to Controller: Product, Action: Add. What sort of coding techniques can I use to handle this dynamic form, such that I follow good or best practice, and if possible also be elegant.
The solution I see so far is to test the Request.Form (or Formcollection) indexer/dictionary for existence for the dynamic input fields. E.g.
public ActionResult Add(Formcollection form)
{
int productEntry = 1;
string productPrefix = "Product";
while(true)

C# - Delete Entries In Static Dictionary When Not Used?
Jul 3, 2010I have a static class that holds a dictionary of objects. I have multiple threads that access this dictionary and create objects on it that are specific to that thread. How and when can I remove entries from the dictionary when a thread is "done"?
Basically this is a static class for an ASP.NET application that all requests can have "isolated objects" (that are related to the current thread) created in the dictionary. But, I don't really want to be tied to ASP.NET.
