    Hi,

    Is there a way to count the number of selected values in a multi-valued report parameter? I know the result of a multi-valued parameter is an object array (Object[]) but I would like to know the number of items in the array. 

    Also, is there a way to know if  <select all> option is checked or unchecked, in other words if all values are selected or not?

     

    Thank you.

    Hi Kanchana,

    To count a number of values in multivalue parameter you can use the following expression in report:
    = Parameters.Parameter1.Value.Length

    To check if all values are selected compare the above value with parameter's AvailableValues.Count value:
    // returns true or false
    = Parameters.Parameter1.Value.Length = Parameters.Parameter1.AvailableValues.Count

    Hope this helps.

    Similar to this:

    Is there a property I can use to see which value(s) are selected?

    If I have selected 1 and 3 in the multi value parameter list...

    I would like to say If parameter.value.contains 1 then do this... if contains 2 then do this...

    IIf (Parameters.Parameter1.Value.Lenght = 1, 'do this 1', IIF (Parameters.Parameter1.Value.Lenght = 2, 'do this 2', IIf (Parameters.Parameter1.Value.Lenght = 3, 'do this 3', 'then selection is either bigger than 3 or = 0')))

    Hope you find it useful!
