我想在运行时更改此网格的特定单元格的背景颜色（显示预订的座位）。我正在窗口加载事件上从数据表绑定此网格。我有像“A33”这样的座位记录。我的绑定代码就像这个。
MySqlConnection mycon = new MySqlConnection(str);
mycon.Open();
MySqlDataAdapter da = new MySqlDataAdapter("select * from Stage", mycon);
da.Fill(dt);
MyGrid.ItemsSource = dt.DefaultView;

change background of specific cell by code :
通过代码更改特定单元格的背景：
DataGridRow firstRow = dataGrid1.ItemContainerGenerator.ContainerFromItem(dataGrid1.Items[0]) as DataGridRow;
DataGridCell firstColumnInFirstRow = dataGrid1.Columns[0].GetCellContent(firstRow).Parent as DataGridCell;
//set background
firstColumnInFirstRow.Background = Brushes.Red;

Your cell-data should have a property IsBooked, then in the DataGrid.CellStyleyou can use a data-trigger on IsBookedto change its backgroud. (There are some other alternativesbesides DataTriggers, but if you just have one boolean conditional i find them to be quite convenient.)
您的单元格数据应该有一个属性IsBooked，然后DataGrid.CellStyle您可以在其中使用数据触发器IsBooked来更改其背景。（除了，还有其他一些选择DataTriggers，但如果你只有一个布尔条件，我发现它们非常方便。）
