Hello, I'm trying to open another from a form, e.g. click on a link on one form and it opens another form in a model dialog and pass data to the second form. I have read that JavaScript can not be used in the code for the form, so must be something in C#? I keeping reading reference to SP.UI.modeldialog, but can't find any working example of how to do this. Can anyone help please. Thank you in advance Vinay

Here is an article that may help: http://blogs.msdn.com/b/infopath/archive/2007/02/26/passing-data-into-a-form-input-parameters.aspx

Alternatively, qRules has a function to easily get an input parameter without writing any custom code: http://www.qdabra.com/en/products/qRules_new.aspx
