RunningValue in a TextBox

[Carlos]

How to I specify the scope as the report?

I am binding a datasource to the report programmatically.
I am not using a table to display the detail data, only textboxes which display field values using "[=Fields.FieldName]".

Thanks.


I want to get this, i use TextBoxs in my detail.

  A                  X                 Y                   Z  (X-Y accumulative)
  a                10                 2                   8
  b       6                 3                  11
  c                  0                 5                   6

The TextBox.Value supports expressions. Just use expression :

=Fields.X - Fields.Y
