View 3 RepliesI 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?
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 want to call an action method when an textbox gets focus to get a description of the model object that field is associated with from a database.
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...
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 need to call a function everytime a visitor visits one of my website's page. But I do not want the execution of the function to interfere with the interface between the user and the website i.e. different thread. What is the best way to do that on ASP.Net?

View 2 RepliesI am using Access 2003 Database and I need to retrieve list of a table's foreign keys and tables they are related to in C#. I used GetSchema() function of OleDbConnection as well as OdbcConnection classes. But It just returns the name of key among few other details.
OdbcConnection con = new OdbcConnection(conStr);
I checking to see if we have any way to return all the keys to array without using the for each loop (there is no constraint for me to use for each loop i am just looking is there any other way)

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?
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?
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.
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?

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.
