DataGridViewCheckboxCell making new row when checked for some reason

I have an application in VB 2008 Expre开发者_如何学JAVAss that uses a DataGridView to display rows of information. I have a DataGridViewCheckboxCell on each row for selecting the row so the user can mass delete the selected rows. For some reason, whenever I try to select a row via checkbox it adds another row to the DataGridView, is there anyway to disable this?

You just need to set AllowUserToAddRows = False on the DataGridView.
