Telerik Aggregate function in code behind

[Sobiya]

Hi,

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];
                this.values.Add(value);
            }

            public object GetValue()
            {
                return this.values;
            }

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

            public void Merge(IAggregateFunction aggregateFunction)
            {
                var otherFunction = (AllValuesAggregateFunction)aggregateFunction;
                this.values.AddRange(otherFunction.values);
            }
        }

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
