Forms Data Controls :: Getting Number Of Queries By The Categoryid
Feb 15, 2011
've made a quiz/score system where a user will go through categories (page by page using querystring) and after submitting his/her score i redirect them to the next page where i show them their score and i also want to show "out of x number of questions".
I've made a query in my dataset:
[Code]....
I get an error about "Cannot implicitly convert type "void" to "object". This is the first time i am trying to use the SQL COUNT so i am almost certain it has something with the way i write it in my BLL, but i cannot figure out why or how to write it as it should. Hopefully you can direct me in the right path?

On a single page, I had got DetailView & Datalist. Datalist contains Category Image(eg Book Image) and detail view will contain products under them (eg Leaning DOS)and in detail view one by one Books(ie Products- eg Leaning Computer) will be displayed.
I had used Detail view to display Product since Products are to be displayed one by one. Now, my Problem is how can I pass category ID to the detail view onthe same page so that on category click it will display corresponding Products in detail view.

I am accepting query/queries from user (our support team) in a text box where user can enter only one query or multiple queries. I need to display result of all queries entered in the textbox. If it is SELECT statement then result of that statement in grid which is done. If UPDATE/INSERT/DELETE then total number of rows affected which is also done but if only one UPDATE/INSERT/DELETE statement is entered in the textbox.
If user enters 2 UPDATE statements and then a SELECT statement then how can I get number of rows affected for individual UPDATE statements just like SQL Server Qury Analyzer displays messages in its result pane.
e.g.
(6 row(s) affected) -- first UPDATE statement
(4 row(s) affected) -- second UPDATE statement
(16 row(s) affected) -- for SELECT statement (grid will also be displayed along with these messages).
I tried almost everything, SqlDataSource (returns count of first statement only), SqlCommand.ExecuteNonQuery and DataAdapter.Fill (returns count of last statement only).

I'm building a web application: some pages will be accessible by non logged-in users (demo and sign-up pages) and others will only be accessible by logged-in users (actual application). In the global.asax file, I'm currently handling the session start event by loading some variable from a query that's based on the UserID. What will happen when a non-logged in user looks at a page? I guess my question is really about how to handle the session start event when it's a logged-in user, when it's not and when a user logs in. I want a certain number of queries to run only once per session, after the user logged in.

I've got the following LINQ query to my IQueryable service
Dim eventcount = EventService.QueryEvents().Count
Dim eventlist = EventService.QueryEvents().Skip((page - 1) * 5).Take(5).ToList
But I'm wondering if there's a way to do this without making two calls to the database?

after googling some hours I came to understand that it is bug in 3.5 framework.
Now I want to retrieve the result.
How do I do thatI tried framing into two seperate iqueryable
var a= first query
var b =second query
ilist result =a.union b
This too results in the same error.

The following code gives error: "When casting from a number, the value must be a number less than infinity."
<asp:TemplateField HeaderText="DATE" SortExpression="date1">
<ItemTemplate>
<asp:Calendar ID="Calendar1" runat="server"
SelectedDate='<%# Bind("date1") %>' VisibleDate='<%# Eval("date1") %>'>
</asp:Calendar>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="Date1" runat="server" Text='<%# Bind("date1") %>'></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
The error occurs at the line <asp:Calendar ID="Calendar1"...>
It errors because there are records with null value for date1 when the records are returned from the database.
Is there a way to specify in the .aspx file telling it to ignore null or display null/blank?

Is it possible to bind data to specfic columns in Gridview?
I mean, if I send a query to my database and it returns 1 column, then bind that column to the first column in the gridview, then send another query and bind the resulting column from that query to the second column without erasing the data of the first column etc etc.

I have a Datalist with 6 elements inside (Labels and Hyperlink)This is in the "results.aspx" page. The process in started by the query stings being sent to the this page:...results.aspx?q=(ItemNameSeached)&cid=(City ID number)I have this bound to an SQL Data Source. My problem is that the ITEM_NAME, ITEM_ID (for the More... link), and the ITEM_BUILDING_ID are in one table in my database; The BUILDING_NAME and BUILDING_ADDRESS are in another table.I have an sql query string working to get the information in the items table but I don't know how to get the Building Information which is on another table. I know the sql query to get the building information (SELECT building_Name, building_address FROM buildings WHERE building_id = @ITEM_BUILDING_ID). My problem is that you can't bound two sql data sources and in the buildings query how do I get the value of the ITEM_BUILDING_ID label into the query.

I have a gridview that pulls data from two tables, CLIENT and PAYMENT. I want to add the edit, delete functions to the gridview for the payment portion of the table, that is to edit or delete the payments but not the client. I've manually enabled the edit, delete functions and input the queries. I've also deleted the textboxes from the templates which draw from the CLIENT table so they cannot be edited. Everything looks good on the surface until I actually go to edit or delete anything, and it has no effect.Here's the structure of the two tables:
CLIENT PAYMENT
ClientID Pk PaymentNumber Pk
FName CLIENT$ClientID Fk
LName PaymentDate
ContactNo NULL PaymentAmount
ArrivalDate PaymentDetails NULL
DepartureDate NULL
CurrentResident
Here's the update query:
UPDATE [PAYMENT] SET [PaymentDate] = @PaymentDate, [PaymentAmount] = @PaymentAmount, [PaymentDetails] = @PaymentDetails WHERE [PaymentNumber] = @original_PaymentNumber AND [CLIENT$ClientID] = @original_CLIENT$ClientID AND [PaymentDate] = @original_PaymentDate
AND [PaymentAmount] = @original_PaymentAmount AND (([PaymentDetails] = @original_PaymentDetails) OR ([PaymentDetails] IS NULL AND @original_PaymentDetails IS NULL))
Finally, here's the delete query:
DELETE FROM [PAYMENT] WHERE [PaymentNumber] = @original_PaymentNumber AND [CLIENT$ClientID] = @original_CLIENT$ClientID AND [PaymentDate] = @original_PaymentDate AND [PaymentAmount] = @original_PaymentAmount AND (([PaymentDetails] = @original_PaymentDetails)
OR ([PaymentDetails] IS NULL AND @original_PaymentDetails IS NULL))

I have a web user control with DataList control in it. In my .aspx page, I have a report header, an empty panel as a place holder, a report footer.In my .aspx.vb file, I'll loop through a list of departments. Within each department, I'll load a label to display the department name and the user control for the data, and add both the label and user control to the panel. So there are two variables:
the number of departments and the number of records in a user control.
Now I need to display the current page number and the total page number in the report footer. Is it doable? How? I'm thinking of this approach: declare a page variable count, count the number of department name labels and the number of records in a user control. When the total count reaches a number, such as 20, I'll break the page. This way, I can get the the page current number and the total number of pages. But how to add a page break to an asp.net page?

I'm currently working on a FOREX Live Trading project that I'm implementing.
I already have a database that stores the CURRENCY PAIR, BUY/SELL, PRICE AND QTY.
But I have a huge problem.
Scenario that is:
A person BUYS EUR/USD at a PRICE of 1.29900 @ quantity 100,000. (This will be recorded in the database table)
Then he BUYS EUR/USD at a PRICE of 1.29950 @ quantity 100,000. (This will then be recorded in the database also)
Then he decides to SELL his EUR/USD at a PRICE of 1.31000 @ quantity 200,000 all out. (How can I check from the database if he previously had make a transaction of BUY/SELL, so that I can do my necessary calculations for the P/L Statement)

I am having trouble with queries because they are not returning the data needed, and I am having trouble figuring out why because I only am testing with 2 records.First I want a query to return all records for one customer as follows:
[Code]....
There are two records with the customerID of 1, but it only returns one,next I try to return only one record, the AccountPrimary or customer_contacts.IsPrimary, but when I add " AND customer_contacts.IsPrimary = 'True' "at the end of my query it then returns both records, but only one IsPrimary = True and the Other = False. Is it backwards? I also tried another method and it returned 30 of the same record and I only have 2

I want to create a page on which the website's sponsors are displayed. The information about the sponsors is coming from the database via an ObjectDataSource, and I'm retrieving an Image (company logo), the name of the company, and a url to the company's website. Each Image (logo) is of the same height, but of varying width. I want each Item to be formatted so that the Image is on top, and underneath is a centered hyperlink with the name of the company.
This all seems pretty straightforward ... now for my problem: I want to display as many of these on the page as possible. Essentially, start off horizontally and fit as many as possible on each row. A DataList or Repeater with RepeatDirection=Horizontal doesn't quite do what I want as I don't want to have a fixed number of columns.
Is there an easy way to achieve this, or do I have to manually add up the width of each item on an ItemDataBound event, and then somehow move to the next row when the maximum width is reached? In addition I have to deal with the fact that the width of my Item is the maximum of the Image width and the text underneath.

I have a table that shows datas from a SQL DB. Some of those datas is numeric ( 1,2,3) and in another table I got the name that represents each number.
ex:
1= Goalie
2= Defence
So I did a Class_filters, in which I associate the number to the right string data.
I was wondering how can I do that in GridView? Is it possible?

I'm sure it was discussed hundred of times, but maybe this time will elucidate some new points )
The question is: do I need to limit number of selected rows in data source for GridView?
When I use paging in GridView does limiting selected rows make GridView work faster?
Now I use ObjectDataSource with Linq in functions.
[Code]....
Does this make sense or I can just use LinqDataSource without thinking of selected rows?
