DataSource Controls :: Static Value Vs Repeat Calculations?
May 13, 2010
I'm building a site where users can purchase 'credits' and buy items on the website with them. I'm wondering, what is the best way of storing the user's overall Credits value? Is it best to do a SUM() of all Credits they have purchased before from the 'Credits.Orders' table, or for performance purposes when they add credits to their account, should it increase a 'Credits' field value in a 'Users' table? For consistency purposes I would like to go with the first option, but the second option sounds better in terms of not running loads of pointless calculations every time I need to know their credit value.

I have the following query:
[Code]....
The results look like this:
DocumentNumber NIIN QtyReq AvailBalance
12345 015551212 2 5
12346 015551212 1 5
12347 015551212 3 5
12348 015554787 10 12
As you can see, the first 3 documents are for the same NIIN, and their total QtyReq is 6, however there are only 5 Available for this NIIN.
I need a way to remove the document 12346 because it cannot be filled, the other 2 document can though. I cannot figure this one out, but it seems like it should be pretty easy.I am using MS SQL Server 200

I have several dropdownlists which are databound to a SQL DB but I am also needing to add 2 items to them. I am using the code below.
With the code in the Calendar1_SelectionChanged sub (Which is when I want it to fire) It loads the data from the sql but not the static content
If I move the code to the Page_Load sub and add "If Page.IsPostBack Then" then it loads the static content but not the SQL.

im developing a silverlight project using silverlight 3, vs2008 and linq2sql. when projects starts, im storing all the data from database into some static list variables. so when ever i need data, im reading it from those static list variables. all i want to know is, is it good to store data in static list variables and use it when ever necessary or is it good to get data directly from DataClassesDataContext object like db.mytable. which is the rite and fastest way or retrieving data. i mean which will use less connections to database?

I have a gridview with the following columns: months, number of injury, expenses. my month column is a string, my number of injury column is a number and my expenses column is a number. I need to first obtain the month column as an integer and then obtain the number of injury column in my gridview. Once these columns are obtained, I want to be able to get the total number of injuries. How do I solve the problem. First obtain the month column and change it to an interger or gridview
Next obtain the injury column and then add each row in the injury column to get the total number of injuries.

In a details or form view I have a number of entries from a database
For example:
Pass-Attempts, Passes-Completed, AvgYds, TdPercentage
If I want to perform a simple calculation on these values, and then display them in the same details/form view
Such as:
QBRating =((Passes-Completed/Pass-Attempts)*100)+(AvgYds*5)+(TDPercentage*4)
With the ideal result being:
Pass-Attempts, Passes-Completed, AvgYds, TdPercentage, QBRating on the same Details/Form view.
So basically I need to programmatically get at those values, perform calculations on them and them display them back in the same control.

I have a FormView Bound to an SQL data source. In the DATA there are 2 columns that i would like to multiply together and display there rate
<asp:TextBox ID="txtPeople" runat="server" Text='<%# Bind("People") %>'></asp:TextBox><asp:TextBox ID="txtRate" runat="server" Text='<%# Bind("Rate") %>'></asp:TextBox><asp:TextBox ID="txtTotal" runat="server" Text='<%# Bind("Rate * People") %>'></asp:TextBox>
This is just an example above but i believe it shows what i am trying to do, there is no calculated column in the database so i can not bind to that directly, and i can not just add the column to the data as its not in my permissions. So how do "Bind" the value of two columns multiplied together to a third text box?

I'm working with a databound gridview that has two columns: a checkbox and zip code. It works fine but upon rendering, it is a very long and skinny two columns which requires the user to scroll down a lot in their browser. I'd like it to be more user friendly and not require so much scrolling. tried to repeat it vertically by adding additional checkbox and databound column but just ended up with duplicate data, not continuing data from the bottom of databound column 1 to the top of databound column 2.Is there any way to repeat the columns vertically and have the data continue?

I have a GridView with column headers that include text and images. I would like to have the header essentially duplicated at the bottom of the GridView. how to accomplish this? I have found some internet resources that have explained how to use the GridView PreRender event to add an extra footer row but I'm trying to find a simple way to populate that row with the same text and images that appear in the header row. I am not using header templates. I am using the footer row of the GridView as the "insert" row.

Basically, an old group created a php page with a drop down and this drop down is populated with entries from a DB. The DB owner is currently absent and for the sake of time, I would just need something that turns the entries in that drop down, always at the same url with the same ID every load into a List. Is there a quick, painless way to do this in .NET?

I have a private static field in my Controller class in an MVC web application.
I have a static method in that controller that assigns some value to that static field, I want to apply lock on that static field until some other instance method in the controller uses the value stored in the static field and then releases it.
DETAILS:
I have a controller named BaseController having a static ClientId field as follows and two methods as follows:-
public static string ClientId = "";
static void OnClientConnected(string clientId, ref Dictionary<string, object> list)
{
list.Add("a", "b");
// I want the ClientId to be locked here, so that it can not be accessed by other requests coming to the server and wait for ClientId to be released:-
BaseController.clientId = clientId;
}
public ActionResult Handler()
{
if (something)
{
// use the static ClientId here
}
// Release the ClientId here, so it can now be used by other web requests coming to the server.
return View();
}

I'm new to .NET and converting and proper way to convert strings to other values. Specifically, here is a situation I'm facing:
I'm returning two values from a datasource as strings. One values is a representation of a span of time, and another is a count of how many attempts to access a system took place within the span of time.
Given these parameters (for example):
Span of time: 00:01:00
Attempts: 13
I'd like to calculate a third value that shows how many seconds each attempt to connect took place during that span of time. This involves converting the time span to seconds and then dividing by attempts. Where I am getting lost is with the conversion of types. I know the span of time needs to be converted to a date, reduced to seconds, then converted to a number to be divided by the attempts field, also converted to a number.
I've been playing around with code segments like this all morning to no avail:
VBNET Code:
Dim thisTime As String = "00:01:00"
Dim thisAttempts As String = "13"
Label1.Text = thisTime
Label2.Text = thisAttempts
Label3.Text = Math.Round(Integer.Parse(Convert.ToDateTime(Label1.Text)) / Integer.Parse(Label2.Text), 2)

I did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.
I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.
For example, my Default.aspx contains a method LoadProducts().
[Code]....
[Code]....
This cannot change. There is no way to convert Business and Data layers to static.
How can I call the LoadProducts() method using ASP.NET Ajax?

I'm working on an ASP.NET web app where I'm using a Wizard to take the client through a large series of steps.One of the steps includes calculating a bunch of numbers on the fly... the numbers calculate properly but when I click "next" and then go back again... some of the numbers are not retained.
function CalculateFields() {
txtSellingPrice = document.getElementById('<%=txtSellingPrice.ClientID %>');
//I get all of the elements like this...
//...
var regexp = /[$,]/g;xt" and then "previous"

What I have is a set of Database records in a DataSource. I can set up a GridView (currently used) to display the data from that set, but I need a bit more complex thing. Say that I have columns Category, ID, Product, Price. What I need is to display Category name, then all the products for that Category, then next Category name, matching products, etc.
