View 2 RepliesOptimization - Why Should Or Shouldn't Store A Dataset - Datatable As A Session Variable In Page
Feb 25, 2010I am working on a web application that is consuming a Dataset returned by a web service. As the application is running I store that Dataset as a session variable to be used over and over again as the user navigates to the different pages that will edit the tables within the dataset. The idea was the user will only have to wait for the data once when the application loads then the application would use the session variable until the user saves the changes they made, when that happens it would pass the edited tables to the service to update the database. Is there problems with this design and the storage of the Dataset and Datatables as a session variable?
View 4 RepliesDataSource Controls :: Use DataTable Instead Of DataSet / Returning One Table?
Apr 9, 2010I'm returning one table. My understanding is that a DataSet can be made of more than one DataTable. I also understand that I can use either of these to return my one table.
Is it better to use the DataTable when I have one table to return instead of a DataSet? Is there any advantage of not using the DataSet in a situation like this? Is there a disadvantage to using the DataSet when only one table is being returned? Does this even matter?
DataSource Controls :: Datatable/Dataset Total Memory?
Mar 16, 2011make a query which will give me 200,000 results and bind it to the datatable but the error will pop out saying out of memory or request timed out.Can datatable/dataset handle these records or is my current server's hardware needs a little upgrade?Actually we are gettings millions of data and i dont have any idea how to solve this one? Have you worked on this kind of data? Do you have any idea on how to send my command from server A to server B while server A also processing request and will not wait for server B's result and server B will just update the records in my database, i think this can solve my problem if doing it in parallel.

DataSource Controls :: Create Interface For Adding Users - Datatable Or Dataset
May 3, 2010I need to create an interface for adding users to .Net Membership DB through an existing database. My Idea is to read each row from database from existing users table in a datatable and then iterate through each row and add it to new database. I cannot directly copy the rows from existing users table because the password stored in .Net Membership provider is in ir-reversible hash code and hashing is done through encryption algorithm present in front end code. My User count is huge (in millions).So what should i use to read the records, Dataset or datatable. Also tell what is the max number of rows it can hold.
View 3 RepliesDataSource Controls :: How To Choose Default DataTable From DataSet For Binding With A DataGrid
Dec 13, 2010I have a DataSet with multiple DataTables and I use an ObjectDataDataSource to bind my DataGrid to it. One of my tables is correctly displayed in the grid. My problem is, that the grid displays the wrong table.
My tables are related to each other - I make use of the "relation" objects in VS Studio 2010. My ObjectDataSource points to a class with a select method. The DataSet contains several DataTables (e.g. "Variables" and "Components").

How can I configure the DataSet to display the table "Variables" by default?
