DataGrid Scrolling problem

[Bob Sneidar]

When I have datagrid display weirdness I do a couple things. First, I get the dgText of the datagrid to see if there isn't unexpected data there. I will also get the dgData to see if there aren't off keys. Once I had a bug in my code that put a key of 0 with an empty value. It didn't display, but it caused issues (can't remember what they were at the moment). 

Another thing I have done is recreate the datagrid. I wrote two functions to "backup" and restore a datagrid. I essentially create an array with all the properties I care about in a datagrid, then restore those settings to a new datagrid.
