ADO.NET :: Looping Through DataSet In C#?
Aug 11, 2010
I have the following line of C# code that successfully returns the results of a stored procudure via a DAL:
spParamGetGamesTableAdapter spGG10 = new spParamGetGamesTableAdapter();I can bind spGG10 to a DataGrid and see the stored procedure query results, so I know everything is good so far.I want to loop through the spGG10 (DataSet table?) and output each row on a row-by-row basis using a Literal Control. I think I know how do the output part,How do I access the data in spGG10 and loop through its records? (Also, I am not exactly sure what kind of object spGG10 really is. Is it a table?)

I am having a problem with this code, i had a post on this however this code is slightly different to that so i thought i would post a spearate thread.
Anyway, what i am trying to do is display job vacancies by the result of a DropDownList value. Now each job name has a description. The problem i am having is i need to display the results in this logic:
Job nameJob descriptionJob location. But what is happening is the job description (body) is repeating the more vacancies there are. This is the page:
http://kidsunlimited.co.uk/vacancies_test_two.aspx
If you select Deputy Nursery Manager from the DropDown and hit the Search button you will see the results. After listing the first two locations the description is repeated and then the 3rd location is shown after this. This is my code:

In my project I work with Entity Framework (LINQ to ENTITY). I only have ADO.NET Entity Data Model and a DAL (Data Access Layer). I also get the data due a WCFClientService. I have a gridview that needed to be exported in Excel.
FlexCel is a tool for generating Excel files based on a template. The only thing I see in demo's is that they work with DataSets.
Is there a way to convert the data in my gridview to a virtual DataSet?
I've written the following method to get the data:

Till now I used to design RDLC file before and assigned typed dataset table columns.Report processing mode is local. But now my stored procedure returns different columns based on condition i.e columns are not fixed every time. Now I need to add that columns to typed dataset and dataset is assigned to RDLC file. So dataset and RDLC files are create dynamically based on stored procedure result set columns.

What I am thinking is this? Is it possible for me to upload the data from an excel file to dataset of my application first, so that the user can view the data in a gridview to review it first, before the user strike the save button, to save it in the database. So, that in case there is a problem, the gridview will high light all the data with an error. So the user can easily pull out the excel and correct the data before saving it in the database.

I have an issue with a Loop that doesn't actually loop. I've posted a simplified version of my code below. Basically, using the NPOI excel library, I have an excel file with data on the first and second sheet, so I need to do a loop to get through both sheets. Below is what I have done so far, however this only works through the first sheet and then exits. It fails to increment the variable w. As you can see, there are other loops implemented in this code which function fine so I don't get it.It's been a very long day and perhaps I'm missing something very simple. I could have it placed wrong or something. If anyone else can spot what I might be doing wrong I'd be very grateful :)

consider the follwing table, this table actually shows which id was given a new id
i.e 11 was assigned 13
again 13 was assigned 15
15 was reassigned 17....and so on actually 11,13,15,17,19 represent the same user (hope u understood)
customerId rejoiningId
11 13
13 15
15 17
20 21
17 19
48 50
21 25
i need to loop through all the rows and find the relation that which all ids are interlinked
say the user enters the rejoining id -13,hence the result should come out to be as 11,13,15,17,19
if user enters 21result should be 20,21,25
it takes a bit of looping statements in query that i couldnt figure out

I'm currently trying to move through all the values added to a listbox by the user, however, I want to retrieve the actual value of each item in the listbox and not the text.
I've gotten so far with the code below, but that only gets the text and not the value.
[code]....
How would I go about getting the value for each item in the collection?

I'm still new to ASP.NET, and I'm trying to rewrite a simple booking/reservation system I did in ASP, but I'm struggling to find an equivalent technique in ASP.NET.
Basically, it a nested recordset. The first recordset returns weeks from a calendar. for each record returned, a basic table row is created, showing the dates & prices then the start of the week is used to query a bookings table to see if there are any bookings for that week. If there are bookings, the <tr> & <td> tags are modified to change to colour & wording to reflect the bookings.
an extract of the code is as follows:

I have several controls on a web form Dropdown list, text boxes etc. Which are going to be used as part of a stored procedure to enter data in several SQL Tables. One of the boxes is called the number of items now depending on the number inputted here is how many items to be inserted therefore I need to loop so my stored procedure to run again
Not sure if this is relevant or just me confusing myself and making this more complex than it really is but I have several data readers running before I run my stored procedure to help get the data I need for it.
Here is the SQL for it and the answer goes in label1 so then further down when the insert stored procedure runs it checks the value on label1 to run an if statement so I will need this procedure to run as well in the loop.

I have the following values: customerNumber, ProductNumber, PartNumber.There exists a directory structure on a server like follows (the bold italic text is the actual value)://myServerName/Parts/Images/CustomerNumber/ProductNumber/PartNumberSo the part of the file directory that is constant is://myServerName/Parts/Images/but the file structure CustomerNumber/ProductNumber/PartNumber will vary, displaying the actual number valuesEX: //myServerName/Parts/Images/11111/22334/007so I need some code that will loop through the file Directory structure under "Images" and will get the string values of each subdirectory. This will be used to find the image to be used for the specific CustomerNumber, ProductNumber and PartNumber.Does anyone have any good sample code where you have done this before?

Which of these will perform better if we assume that the IF block in #1 will be executed more and less in #2
foreach()
{
if
{
block here
}
}
or
foreach()
{
if !( )
continue
}
I've structured #2 to take the if conditional less often.

to loop through each field in a record to test for a value and then set a flag at the end of each record if an instance of this value occurs in any fields?I have a table where some fields values are have a *c* at the beginning of the text eg "*c* value" . What I would like to do is run a select query off the table and at the end of each record have a field called "Change Flag" and a value of "Changed" or "No Change" depending if a *c* has been encountered.
There are a number of tables to run this against all with differening numbers of fields/

i have searched quite a bit on this one and can't seem to find exactly what I am looking for.
I think my first problem is this: How would I bring back a DataTable FOR copying? I know I would need:
Dim dt as Datatable
But then how do I get the Original Datatable in there? I think that once I have that part, I can just make a connection to my new DB inside a copy subroutine (using the .Copy method) and be done with it. That part I have the code pretty much done for, I think.
