Filter Data using parameters (in vb.net)

I am trying to use reporting services with vb.net. Since there is no EASY way
to pass dataset to the reporting services (i understand until Vs.net2005). As
an alternative below is what I am thinking of.
I am using vb.net and trying to dynamically generate the SQL to control the
filter. In the initial report definition I have the base SQL get a large set
of data and filter the data within the report format.
How do i pass filter the report data by using parameters. Has anybody got
any sample code?
I have checked the available paramters and what they are supposed to be used
for. They are:
rs prefix (which uses the Command, Format, Snapshot paramters)
rc prefix - i.e type of format
Not sure how I can use the existing parameters so that I am able to filter.
Please help,
Rgs,
MehulI just had a similar issue, I was returning a large set of data for a graph,
and wanted to use the same data to show only a single row, so I put a table
and filtered the data based on the parameter passed into the report.
1.) add the table
2.) set upt he rows and headers to show
3.) click on table and select properties
4.) click filters
5.) in left column, select the field name that you want to filter on
6.) in second column choose relationship
7.) in third columns, select expression, then choose parameters from the
tree and select the actual parameter to filter based on
8.) the filter looks something like Fields!filedName.Value =Parameters!parameterName.Value
you may have to explicitly cast these both to ints
CINT(Fields!filedName.Value) = CINT(Parameters!parameterName.Value)
And at this point, you have your form element showing only data that matches
the parameter that was passed to the report.
Hope this helps
