private void 刪除ToolStripMenuItem_Click_1(object sender, EventArgs e)
{
try
{
DialogResult dr = MessageBox.Show("確定刪除嗎？", "提示", MessageBoxButtons.OKCancel);

//獲取選中行的數據
Facade.FoodMenuCateFa?ade fa?ade = new Facade.FoodMenuCateFa?ade();

t_Food.CateName = dataFood.CurrentRow.Cells[1].Value.ToString();
int list1 = fa?ade.DeleteFoodMenu(t_Food);
frmTips f = frmTips.GetInstance("刪除完成");
f.Show();
}
}
catch (Exception ex)

Entity.T_FoodMenuCate t_Food = new Entity.T_FoodMenuCate();
List<Entity.T_FoodMenuCate> list = fa?ade.SelectFoodMenu(t_Food);
//把值賦給表格
dataFood.DataSource = list;
}
