Passing DataSet's into Custom Code

Is it possible to send a DataSet to a Custom code from the report. I am
planning to use .net dll's in my report as a custom code.
ThanksIf you mean an RS dataset you can't because RS datasets are not exposed
programatically. Some workarounds you may consider:
1. Retrieve an ADO.NET dataset in your code using the same query. In other
words, clone the dataset.
2. If the report has a matrix region, you can redirect the matrix region to
read its values from an embedded function. In this way you can populate a
custom data structure, e.g. an Array or an ADO.NET dataset, which you can
pass the external assembly. As a practical example, you may want to look at
my report sample "Sales by Product Category" which collects the matrix
region data in an array and sends it off to an external assembly to get
forecasted sales.

Hope this helps.

previous columns within the same row, look into calculated fields. If you want more control over
the dataset manipulation, you can write your own Data Processing Extension which reads in the
dataset and performs whatever logic you want to do on it prior to submitting the data to the report.

there.
Without writing a DPE, if you have a dataset with two columns returned (Quantity and Price) and you
need a third column computed (Total), you can either add a column to your table with this
expression:
=Fields!Quantity.Value * Fields!Price.Value
or you can right-click in the Fields window in Report Designer and choose Add Field. You can create
a new computed field named Total and tell it to always have a value equal to the above expression.
To sort, you should attempt to sort the data in the database prior to being sent to the report. If
that isn't possible, look in our Books Online for more information on how to Sort rows shown in
tables.
