Question

Hi all,

The snapshot what you see is the crystal report. From crystal report we export to pdf or any. As soon as i click the print icon on the left side a new pop up to export to pdf opened

 

When this pop up is opened i just want to make selection in the form back of it(check or uncheck the two check boxes).Depending on the two check boxes i need to generate as both excel and pdf. how to make the form active when print dialog is opened.please anyone help.
