I ran into this problem and was curious what others think. I have a web app with 3 datagrids on. Each datagrid I am creating a datatable from a database then binding it to the datagrid. 2 of the 3 datagrids have about 6,000 records in, and the 3rd has about 25,000. I also have a button that allows you to print out by a certrain criteria. My problem happens when you click the button, if i have all my records in the datagrids, the button doesnt go into the on click, i just get a page can not be displayed. If the 3rd datagrid i reduce the number to 20,000 everything works fine. I then went and added a column to the 3rd datagrid. When I click the button i get the same page can not be displayed. So I reduced that number down to 17,000 and everything works fine again. The only thing that I can think is that there is a maximum size to a datatable that can be bound to a datagrid. I'm not sure if that is true. I was curious if anyone else had a problem like this, or any ideas as to what is causing this.

Thanks.
