Hrybrid behavior of the refresh command of the crystal report viewer?

Question

hi,
In a button click event the crystal report support retreive a value based on a value entered to a seach box, at the last line of the button_Click( ) i have put reportviewer.refresh( ). this should load the report with new values to the report viewer.
Also there is a refrsh button on reportviewer, when i click it asks for the search value and the dialog comes from crystal reports not from C#, How do i disable this? (the Dialog comes form crystal report)
