WPF 后台添加DataGrid

public DataGrid CreateDataGrid()
        {
 //自定义DataGrid
            DataGrid dataGrid = null;
            dataGrid = new DataGrid();

            dataGrid.Height = 340;
            dataGrid.Margin = new Thickness(10, 30, 0, 0);
            dataGrid.IsReadOnly = true;
            dataGrid.AutoGenerateColumns = false;
            dataGrid.CanUserResizeColumns = false;
            System.Windows.Data.Binding binding = null;
            binding = new System.Windows.Data.Binding("E_ID");
            binding.Mode = System.Windows.Data.BindingMode.OneWay;
            DataGridTextColumn dgtcE_Id = null;
            dgtcE_Id = new DataGridTextColumn();
            dgtcE_Id.Header = "列头1";
            dgtcE_Id.Width = 70;
            dgtcE_Id.Visibility = Visibility.Collapsed;
            dgtcE_Id.Binding = binding;
            dataGrid.Columns.Add(dgtcE_Id);
            binding = new System.Windows.Data.Binding("E_Type");
            binding.Mode = System.Windows.Data.BindingMode.OneWay;
            DataGridTextColumn dgtcE_Type = null;
            dgtcE_Type = new DataGridTextColumn();
            dgtcE_Type.Header = "列头2";
            dgtcE_Type.Width = 200;
            dgtcE_Type.Binding = binding;
            dataGrid.Columns.Add(dgtcE_Type);
            binding = new System.Windows.Data.Binding("E_TypeName");
            binding.Mode = System.Windows.Data.BindingMode.OneWay;
            DataGridTextColumn dgtcE_TypeName = null;
            dgtcE_TypeName = new DataGridTextColumn();
            dgtcE_TypeName.Header = "列头3";
            dgtcE_TypeName.Width = 200;
            dgtcE_TypeName.Binding = binding;
            dataGrid.Columns.Add(dgtcE_TypeName);
            binding = new System.Windows.Data.Binding("E_State");
            binding.Mode = System.Windows.Data.BindingMode.OneWay;
            DataGridTextColumn dgtcReveaState = null;
            dgtcReveaState = new DataGridTextColumn();
            dgtcReveaState.Header = "列头4";
            dgtcReveaState.Width = 120;
            dgtcReveaState.Binding = binding;
            dataGrid.Columns.Add(dgtcReveaState);

 //DataGrid中Column的内容居中
            Style styleRight = new Style(typeof(TextBlock));
            Setter setRight = new Setter(TextBlock.HorizontalAlignmentProperty, HorizontalAlignment.Center);
            styleRight.Setters.Add(setRight);
            foreach (DataGridColumn c in dataGrid.Columns)
            {
                DataGridTextColumn tc = c as DataGridTextColumn;
                if (tc != null)
                {
                    tc.ElementStyle = styleRight;
                }
            }

 //表头居中
            Style style = new Style(typeof(DataGridColumnHeader));
            setRight = new Setter(DataGridColumnHeader.HorizontalContentAlignmentProperty, HorizontalAlignment.Center);
            style.Setters.Add(setRight);
            dataGrid.ColumnHeaderStyle = style;

            return dataGrid;
        }

设置满足某条件行的背景色

private void datagrid_LoadingRow(object sender, DataGridRowEventArgs e)  
        {  
            var drv = e.Row.Item as DataRowView;  
            switch (drv["ID"].ToString())  
            {  
                case "1": e.Row.Background = new SolidColorBrush(Colors.Green);  
                    break;  
                case "2": e.Row.Background = new SolidColorBrush(Colors.Yellow);  
                    break;  
                case "3": e.Row.Background = new SolidColorBrush(Colors.CadetBlue);  
                    break;  
            }     
        }
