In SSRS Show the Serial Number in Reports Automatically Using Expression in .NET

 Serial Number in SSRS Reports 

Purpose: I want to add the sequence number or serial number to every row.

Solution

To do this I will use an expression named "RowNumber".

1. Insert a new column on the left side and name it "Serial No."
   
   
   
2. Create the expression by right-clicking on that column as in the following:
   
   
   
3. Select the "Miscellaneous" as a category and "RowNumber" as an item, then expression will be like:
   
   =RowNumber(nothing)
   
   
   
   Where the nothing keyword indicates that the function will begin counting at the first row in the outermost data region. Click the "OK" button.
   
   
    
4. Run the "Default.aspx" page.
