DatagridView Clear

[christianbg]

I am using datagridview.rows.clear() to empty a grid that i am bind the rows to using the datasource and datamember properties and the error i keep getting tells that i can't clear it. is there another way to empty the grid?

Have you tried setting the DataSource to Nothing? Or to a query that returns no records (e.g., SELECT * FROM Table WHERE 1 = 0)?

I am trying that and it still doesn't clear the grid, the old information is still there. The table i am using to load the grid with I remove then rebuild altogher, it doesn't even always have the same columns

This seems to work for me:

DataGridView1.DataSource = Nothing
DataGridView1.Refresh()

Have you tried using the STL? There is an algorithm called next_permutation which given a range will return true on each subsequent call until all permutations have been encountered. Works not only on strings but on any "sequence" type.
