Programmatically creating DataGridView with customised items in each cell

Setup The DataGridView

	//----- CREATE THE DATAGRID VIEW COLUMNS -----
	dataGridView1->AutoGenerateColumns = false;
	dataGridView1->DataSource = nullptr;			//Clear the grid if necessary
	dataGridView1->Columns->Clear();

	//TEXT BOX COLUMN
	DataGridViewTextBoxColumn ^DataGridColumnString1 = gcnew DataGridViewTextBoxColumn();
	DataGridColumnString1->HeaderText = "My String Column";
	//DataGridColumnString1->ReadOnly = true;
	//DataGridColumnName->SortMode = DataGridViewColumnSortMode::NotSortable;
	dataGridView1->Columns->Add(DataGridColumnString1);

	//BUTTON COLUMN
	DataGridViewButtonColumn ^DataGridColumnButton1 = gcnew DataGridViewButtonColumn();
	DataGridColumnButton1->HeaderText = "My Button Column";
	//DataGridColumnButton1->ReadOnly = true;
	dataGridView1->Columns->Add(DataGridColumnButton1);

	//IMAGE COLUMN
	DataGridViewImageColumn ^DataGridColumnImage1 = gcnew DataGridViewImageColumn();
	DataGridColumnImage1->HeaderText = "My Image Column";
	//DataGridColumnImage1->ReadOnly = true;
	dataGridView1->Columns->Add(DataGridColumnImage1);

	dataGridView1->Columns->Add(DataGridColumnComboBox1);
	
	dataGridView1->Columns[0]->Width = 120;
	dataGridView1->Columns[1]->Width = 80;
	dataGridView1->Columns[2]->Width = 60;
	dataGridView1->Columns[3]->AutoSizeMode = System::Windows::Forms::DataGridViewAutoSizeColumnMode::Fill;

	//----- ADD THE ROWS -----
	//Row 0
	dataGridView1->Rows->Add();
	dataGridView1->Rows[0]->Cells[0]->Value = "Row 0";
	dataGridView1->Rows[0]->Cells[1]->Value = "Button 0";
