You have to manage also the case when RowIndex of the grid is -1. In you case you should add the next code before to access the row cell.

C#

if(index <0)
{
   return;
}
//
GridViewRow row = GridView1.Rows[index];
//...

You should manage this special case when GridView1_RowCommand1 event is generated with index -1 and this is nor related with split.
