Q: Can we use data-grids for our report in SSRS?
We have an ASP.NET project that populates a data-grid. Using data-grid as my data-source for my report using SQL Server Reporting Services. Is this possible? The simple answer is no. However, nothing's ever simple. A set of reporting controls was added in Visual Studio 2010 allowing you to report in a data-set, on data that was supplied by you. So, if you retrieved your data into a data-set, bound the data-grid to the data-set so it had data to display, you could then use that data-set as the data-source for the reporting controls. These are then client-side reports, not server reports though.
