Extra column appearing when paging in Telerik RadGrid

I'm getting a blank column when switching to another page using the default pager in the telerik radgrid. As data for each row, it shows the type of data i am using for the rows (SearchRecord)

Anyone have any clues as to why this may be happening? It doesn't show up on initial population of the grid, but only when I do paging. My columns are built dynamically but i confirmed that when my c开发者_StackOverflow社区olumns are built, they are the correct number.

thanks very much in advance.

I figured it out. Thanks. I'm just rebuilding the columns on page load.
