interface is a collection of method declaration and constants that one or more classes of objects will use.Interface definition is same as class except that it consists of the method that are declared have have the parameter list.

I am working with asp.net 2005 and Crystal report 10. I have an image field on my dataset to show on Crystal report.And the image is shows dynamically from database in image field of CR. The image field is showing well on my Crystal report on its first page with all other data but when i click to open second page of CR,it does not show any data on that.I found that this is because of adding the image field on crystal report. Because when i remove the image field from the CR then it will run both the pages of CR. I am using the Page Load event to bind CR data with Database. And i have already check with the Init event to bind CR , but it still not shows the data on second page when i use image field on that. Please give solution for that.....
