I am using ASP.NET/C#.I am using Report Viewer control to display a basic report.Currently the data is shown properly however the column names are the same as when selected while configuring the Report Wizard.
Example:
cFirstName is displayed as cFirstName in the column header of the Report Viewer.
I would want to change it to First Name instead.
Here is the image of the issue.

Can anyone help me to achieve this?
Any suggestions are welcome.
Thanks.
You can set this in the rdl, rdlc file.
This is where it should normally be done.
It cannot be done through c#, unless you take that column name as a report parameter and set the column header using that parameter.
