GridView Row

to create new table i say use stored procedure (SP), so your SP will look like this:

Algorithm is
create procedure TableCreation 
@tableName nvarchar(max)
as
create table @tableName (Col1 int, Col2 int)
return;

Now, at select row you can fire event , e.g., use any DB framework to fire this procedure

grid_selectRow()
{
    DB.Execute(TableCreation('abc'+grid.rowNo));
}
