how to print multivalue parameter in textbox

[Lukasz]

Hi,

I have multvalue parameter with available values connected to ObjectDataSource:

IEnumerable<int> GetMonths()

Now I am trying to display first value from that list in TextBox:

{=First(Parameters.Months.Value)}

This renders as empty.

But this works:

{ = Join(",",Parameters.Months.Value)}

How can I use agregate fuctions on multivalue parameters?

Thanks,
Łukasz

Hi,

As far as I know the Parameters.Param.Value of multivalued parameter is a System.Object[], and is not operating as a standard field. Probably a user function can get the needed value, just pass the Parameters.Param.Value or Parameters.Param.AvailableValues and cast it.

Yes, thanks.

I finally ended using user functions to extract everything what I need from multivalue parameters.
