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.

View 9 RepliesIs there a straightforward way to create a dataset after querying a dataview? The query itself returns DataRowView objects, which I cannot get to work with CopyToDataTable().
The query looks like:
Dim dvQueryView As DataViewdvQueryView = (dataview object of large dataset)
detailTableQuery = From rowView
As DataRowView
In dvQueryView _
Order
By sSortOrder _
Select rowView _
Skip nQuerySkipRow _
Take nQueryCountRows
I only want a small selection of records from the large dataview and use those to create a smaller dataset. The large dataset stays in place while multiple views are created from it, and then from those views I want to create the smaller datasets.

View 3 RepliesI'm use to programming in vb.net and doing MsReports.I will add a DataSet with a datatable and then I will add a report.I will populate the report screen with the columns from my dataset which will be available in my toolbar on the left-hand side of my screen. It is a basic drag and drop action.I followed my usual steps in asp.net, but when I try to draw the report, I can't find my dataset.
Why is this?The dataset is named: "dsReport.xsd".The toolmenu where I should see this dataset is labeled: "Website Data Sources"
Can I read from a dataset and create a hierarchical horizontal menu?

View 1 RepliesI 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.

In C# ASP.NET 3.5 web application, I need to export multiple datatables (or a dataset) to an Excel 2007 file with multiple sheets, and then provide the user with 'Open/Save' dialog box, WITHOUT saving the Excel file on the web server.
I have used Excel Interop before. I have been reading that it's not efficient and is not the best approach to achieve this and there are more ways to do it, 2 of them being: 1) Converting data in datatables to an XML string that Excel understands 2) Using OPEN XML SDK 2.0.
It looks like OPEN XML SDK 2.0 is better, please let me know. Are there any other ways to do it? I don't want to use any third-party tools.
If I use OPEN XML SDK, it creates an excel file, right? I don't want to save it on the (Windows 2003) server hard drive (I don't want to use Server.MapPath, these Excel files are dynamically created, and they are not required on the server, once client gets them). I directly want to prompt the user to open/save it. I know how to do it when the 'XML string' approach is used.
I have a problem that I have been trying to solve the past two days, but I cannot figure it out...I have a folder which will have 60-70 Excel Files or CSV Files (they are right now). There are no headers in them, but they all have the same # of columns and the columns are in the same order in each fileI need to read each file in the folder, grab the data from the file and put it in a Database file. So all files will be read and then the data from them I guess put in a DataSet and then put into a Database (SQL).
