I had the same "problem" today. I also wanted to hide buttons of certain rows. After playing around with it for a while, I discovered a very simple and nice solution, that doesn't require any overloaded paint()-functions or similar stuff:

Just assign a different DataGridViewCellStyle to those cells.
The key is, that you set the padding property of this new style to a value that shifts the whole button out of the visible area of the cell.
That's it! :-)

Sample:

System::Windows::Forms::DataGridViewCellStyle^  dataGridViewCellStyle2 = (gcnew System::Windows::Forms::DataGridViewCellStyle());
dataGridViewCellStyle2->Padding = System::Windows::Forms::Padding(25, 0, 0, 0);

dgv1->Rows[0]->Cells[0]->Style = dataGridViewCellStyle2;
// The width of column 0 is 22.
// Instead of fixed 25, you could use `columnwidth + 1` also.
