DataSource Controls :: Multiple Result Sets Vs Multiple Data Readers?
Jun 4, 2010
Would it be better to have a sp return multiple result sets and use NextResult() or have subsequent call to dr.execute.... () and hadle one result at a time?
To me using nextResult() on a multiresult datareader would be cleaner and easier - but it does not seem to be very "atomized". I guess I am wondering can the cost of executing multiple commands be neglected? Seems like executing multiple commands and receiving a single result set would also be easier to read/test/understand.

I am using a sql stored procedure which returns multiple result sets. By default Sql Datasource is binding the first result set to gridview. I want the second result set to be binded. I browsed all the properties in Sql datasource but could not find one to set this.

I have a complicated report that nests six deep and so really hits the database hard. I want to use SqlDataReaders NOT DataAdapters and DataSets because I don't want big tables in memory.
MARS can get me the data fast, all from the one connection. But all the examples show it binding to a treeview.
I want to bind it to nested GridViews (six deep!).
Any examples of MARS binding to nested gridview/list/repeater controls of any kind?

I have a table that contains a date column along with others. I need to extract two sets of data from this table for two different time periods. Call them Current and Previous, so that I can compare them line for line. There are exactly the same number of days in both time periods.
The problem is that I need to return the data like this:
CurrentDate, Count(CurrentItems), Sum(Amt), Count(PreviousItems), Sum(PrevAmt)
JOIN puts the data into the result vertically, so that doesn't work. So far, I have not found a method that will arrange the data correctly.

I am working on a site in which as user logs in (first database request) the stored procedure varify password and user id and then returns user record that I put in session to use next.
After this I do a second db request. it returns addresses of user which I put in cache.
I can get both sets of data (user record and his address from 2nd table) in one database requests.

I have a form where the user enters their first name, last name, email address etc.. and then they also have the ability to enter 'cottages' that they are interested in viewing (ie. The cottage name, cottage address). The user then needs to be able to 'save' this somewhere and enter another cottage into the same form.
Finally the user will submit the form, and all the user details, and cottage details will be emailed to admin.

I have an inventory page with a gridview that shows 1 item per record, each item starts with a checkbox in the gridview. Currently users can select multiple records and hit the order button and everything has worked well. Now I have multiple pages in my gridview, and if a user selects a few records from the first page, and then goes to the second page, all the records (checked checkboxes) disappear from the first page.

I create reports sometimes with a gridview and export the data to excel. Lets say I have like multiple gridviews and I wanted to export each gridview to excel under its own spreadsheet.
So gridview1, gridview2, gridview3 are exported to excel under $heet1, $heet2, $heet3.
I know how to export multiple gridviews to 1 excel sheet but I don't know how to export them separately under their own spreadsheet.
I've been researching online, and i'm continously searching, but does anyone know how to do what i'm trying to do with the gridview and excel or is this not possible?

I am not able to find the projects related to working with excel sheets by using ClosedXML to refer. I have an excel book which contains two sheets.
In sheet 01: In column A: In B: In C:
Student name01 Student's phone number blabla
Student name02 Student's phone number blabla
Student name03 Student's phone number blabla
In sheet 02: In column A: In B: In C:
course name01 computerscience blabla
course name02 dhfsthshbstgs blabla
course name03 garsfghsefrgs blabla
now, I would like to see in two comboboxes (all the words/text presented in the column A) from two sheets, the student name and course name and then I want select any student name and course name of my choice. Afterwards, when I click on a button, my program should display the students phone number and the course name (from column B from both sheets) and related things present in the Column C D E.. of the selected things in combobox in a label or a in a textbox.
PS: I solved the following problem: I can select student name in one combobox and print the the corresponding data from the only one column B (but I worked only with one sheet). It is bit complicated for me to continue with two sheets.
