Disabling One Input Parameter...?

Hi All,
I am creating a report which calls for four input parameters A, B, C, and D.
How can I disable D if A, B, and C are selected or disable C if A, B, and D
are selected?
Thx, ChuckThis is not supported. The only way to achieve this right now is to
implement your own front end application which handles the parameter UI and
then e.g. uses SOAP or URL-access to pass the "validated" parameters to the
report server.

as well. Use the from query section in the report parameters and create a
query which points to this table. Set your Non-queried Default value to
NILL.
Create a dataset for each report parameter. Some duplication, but is quick
and it works. Have done it for database table and columns names where one
or more can be selected and the column info is passed back as a results
alias and is returned independently of the other report parameters.
Eg. DBTableNames
Select Name, Id
From sysobjects where xtype ='U'And ID <> 197555541
Order by Name
DBTablesColNames relys on a tablename to be selected before the report will
allow the selection of a column
Select Name
From syscolumns
Where id = (Select Id
From sysobjects
Where xtype = 'U' AND Name = @.DBName)
** @.DBName = Parameters!TableParameter.Value **
I had to implement custom code in order for this to be of benefit.
Eg. Dataset CustomSQL
= Code.GetSQL(Parameters!TableParameter.Value, Parameters!
ColumnParameter.Value, Parameters!EndDate.Value, Parameters!Interval.Value,
Parameters!NoOfIntervals.Value)
As you can see from the dataset CustomSQL this is one of my so called
"Adhoc Reports" which allows the user to choose a database table and one of
its columns with a given date, an iterval (ie. Daily, Monthly etc), and the
No. of intevals. I have three tables on the report page that each call this
dataset passing in their own report parameters.
Note you have to manually set the name and database feild under "Fields" to
Results to get any data back
