    I am working on telerik reports and used a function for selecting all values by default
    for multivalue parameter, i am using value in parameter like 'AllValues(Parameters.ParameterName.Value)',
    and function is written in report code behind as-

    [AggregateFunction(Description = "Collects all values", Name = "AllValues")]
            public class AllValuesAggregateFunction : IAggregateFunction
                ArrayList values;

                public void Accumulate(object[] values)
                    var value = values[0];

                public object GetValue()
                    return this.values;

                public void Init()
                    this.values = new ArrayList();

                public void Merge(IAggregateFunction aggregateFunction)
                    var otherFunction = (AllValuesAggregateFunction)aggregateFunction;

    now i have some parameters which are added from code , how can i use this function for those parameters
    this.ReportParameters["Department"].Value= ??

    I guess you can use the same expression:
    this.ReportParameters["Department"].Value= "AllValues(Parameters.ParameterName.Value)";

    or you can directly assign the collection of the real parameter values 
    this.ReportParameters["Department"].Value= DepartamentParameterValuesList; //this is some collection of the actual values
