Forms Data Controls :: Deleting A Record On A File With Multiple Keys / Access The Rest Of The Keys?

Feb 8, 2010

I have a DataGrid that I need to be able to use to delete records form a file

[Code]....

[Code]....

I use

((TextBox)GridMenuOptions.Rows[e.RowIndex].Cells[1].Controls[0]).Text;

To access the data in the Grid for updating, but it doesn't work for deleting

I can use

string id = GridMenuOptions.DataKeys[e.RowIndex].Value.ToString();

but that only returns the first key.

How do I access the rest of the keys?

Configuration :: Web.config AppSettings - Keys Referencing Other Keys?

Dec 7, 2010

My current project has many peripheral systems and many different environments (testing, integration, development etc). As expected, we're using .config files to dynamically manage everything.

Instead of updating each relavant key when deploying to an environment, I was hoping there was a way to change 1 key only. Such as:

<add key="Environment" value="Development"/>

<add key="WebServiceLocation" value="http://<<Environment>>/text.asmx"/>

I've done some searching and haven't come up with an elegant solution. I'm aware that .config files can make use of system variables, but this seems like a bit of a high wire act.

I have this jQuery function:

It works fine as far as getting the test text, but the problem is if I set a breakpoint in the action method, I see that it gets called over and over, not just when i change focus in the text boxes...

C# - Async Function Thread.Sleep In Web Application?

Sep 8, 2010

I maintain a ASP.NET web application that causes a user's network connection to reset for several seconds when it executes a procedure. Therefore, the page request times out on the user's end as they never receive the web application's response (the connection dies before it gets the response packet).

To resolve this situation, I was contemplating having the ASP.NET page execute an asynchronous function that incorporates a Thread.Sleep(5000); // sleep for 5 seconds before executing the connection reset This way, the browser has 5 seconds to receive the page's response before their connection resets.

I have concerns with using Thread.Sleep and asynchronous functions in ASP.NET though. I've never attempted to do it before, so I'm unsure of the potential problems it may cause. Does anyone see potential problems with starting an asynchronous thread that contains a Thread.Sleep in an ASP.NET application?

I have an MVC3 with EF4 project. I have a screen for order .Order has 2 id's inside it for Billilng and Shipping AddressID .When I go and create a new order these fields render as single textboxes as Ids'Question is how can I render full address textboxes (addressline1,city,state,zip etc) do I have drop in the html markup for them? In that case while capturing the data back I willl have to go with classic way of retrieving name/value pair and then do insert into address bring back that identity and update the order record...?

Create(int customerID,FormCollection fc){}

So the main question is how can I do ModelBinding with foreign keys?

How To Get MVC To Generate Fields For Foreign Keys In EF

Nov 10, 2010

I have an EF model with a table with several foreign keys. These foreign keys are managed by associations. In code, I can get a strongly typed list of objects when I access that property on the object.

When I generate a strongly typed view, all I see are the int fields. Is there a way to get ASP.NET MVC to bind to the objects that are related as well as the main object?

Encrypting Foreign Keys From Database?

Nov 7, 2010

I just came across some code that seems to encrypt database keys prior to sending them to the client (WebBrowser, Silverlight, etc).

To illustrate, suppose you have a list of students to extra-curricular activities, and a relationship defined between them. Every time the data is written out to the ASPX page, the studentID and activityID is encrypted. Every time a write, or modify is made, this value is sent back to the server, decrypted, and saved to the database.

What could be the reasons to expose data this way? Is this a normal practice?

MVC :: Compound Primary Keys In DB Design?

Mar 2, 2010

I'm getting up to speed with MVC. In all examples that I find, the database tables always seem to have a single autoincrement column as the key. Is this the standard for DB Design when the intent is to use MVC or can MVC cope with compound primary keys that dont necassarily have autoincrement?

Typical DB Design:

[code]....

It's just that obviously in the real world many companies already have a good DB design populated with data based on the classic design style. If I get clients contemplating updating their applications and want to use the MVC framework, will they also need to consider the redesign of the DB?

If MVC can cope with compound key's are there any good examples. I thought that by using binding exclude/include that compound keys are possible, but it wasn't clear to me.

Security :: Store Db Keys In Javascript?

Sep 26, 2010

I'm working on a mapping application and will be allowing a user to make a query and have the resulting locations display on a map.I want the users to be able to interact with the map, but I need to know exactly which item they're interacting with, so it would be easiest if when the original query is made, the id's are put in a hidden field somewhere so I can just perform an insert statement based just on the key, rather than having to to another query to find out the key by saying "where location name is x and the coordinates are y, and the description is z" etc.Is this a bad idea, i.e. could anyone do any harm if they discovered that I was storing the primary key in a hidden field?

Insert Foreign Keys With Dynamic Data?

Mar 21, 2011

I am having trouble with foreign keys Dynamic Data and entity framework 4.0. It feels like there is a problem with the entity association but I am not sure. I have multiple fields representing the foreign key on the insert page.

When I try and insert data I get an error A dependent property in a ReferentialConstraint is mapped to a store-generated column.

Column: 'CommentId'

My data is a very basic one to many relationship, the foreign key in question is BookId in the Comment Table.

[code]...

When I let the scaffolding do its thing, I get multiple fields representing the foreign key.
