Report Viewer Parameters in Visual Studio 2010 - No Code

Hi Folks,

I've been trying since a long time finding an article of how to pass parameters to a Report Viewer control in Visual Studio 2010, but most of the articles needs lots of code to be written.

But, now I have found the way to create a report and pass parameters easily with only 1 line of code, yes I am serious 1 line of code!! :)

And below I will describe the steps with screen shots:
1- You need to create a new Visual Studio Web Site:

2- Then you will have an empty web site.

3- Now, I will create a new database with one table with three columns (ID, Name, City):

Then fill it with some data:

 Now I will create a data set for the Contacts table:

 Now I will Rebuild the web site:

Now, we need to add reference to Microsoft.ReportViewer.WebForms:
Make sure to select Version 10.0.0.0

Now, I will create a report:

Save the report.

Now, I will start to build the page of the report:
- Add a DropdownList and a Button:

- Drop a Script Manager control into the page:

- Drop a ReportViewer control:

- Choose the Report we created before, and an ObjectDataSource will be created directly:

- On the Click event of the button write the only Code you need to write to refresh the report:
ReportViewer1.LocalReport.Refresh()

Congratulations!! the web site is ready and the report takes the parameter and refreshes.

Happy programming!
