I am trying to implement paging in my detials view which is bound to a data table created at run time from a .txt file the user uploads

when i run the program and click page 2 this is the error i have gotten

'DetailsView1' fired event PageIndexChanging which wasn't handled

I cant seem to determine how to correctly implement this. From what i am reading I thought I could just bind the Details View to the table, which is what i do in my code-behind since it created at run time
