笔者刚刚接触WPF,菜鸟一枚,在做一个练手程序时遇到这样一个需求,创建一个新的Grid并将其添加至一个ListView中,要求Grid及其子元素应按一定顺序给Name属性赋值,直接使用XAML创建的话重复代码过多,且新建一个Grid时名称重复,C#代码创建虽然代码量较大,但是很好的解决了这一问题,可以广泛应用,下面就贴出代码与诸位分享一下,代码质量不高,需要改进的地方还请诸位大神多多指教。 在函数外定义了一个变量Entries用于计数。使用数据绑定使得该Grid前几列与之前XAML中定义的标题宽度一致。 1 public Grid newgrid() 2 { 3 Grid grid = new Grid(); 4 grid.Name = "grid" + Entries.ToString(); 5 6 RowDefinition row1 = new RowDefinition(); //实例化一个Grid行 7 ColumnDefinition co1 = new ColumnDefinition(); //实例化一个Grid列 8 ColumnDefinition co2 = new ColumnDefinition(); 9 ColumnDefinition co3 = new ColumnDefinition(); 10 ColumnDefinition co4 = new ColumnDefinition(); 11 ColumnDefinition co5 = new ColumnDefinition(); 12 ColumnDefinition co6 = new ColumnDefinition(); 13 ColumnDefinition co7 = new ColumnDefinition(); 14 ColumnDefinition co8 = new ColumnDefinition(); 15 //将前三列的宽度与在XAML中定义的标题宽度绑定 16 Binding binding1 = new Binding(); 17 //设置绑定数据源对象 18 binding1.ElementName = "titleco1"; 19 //设置源属性 20 binding1.Path = new PropertyPath("Width"); 21 //进行数据绑定 22 co1.SetBinding(ColumnDefinition.WidthProperty, binding1); 23 24 Binding binding2 = new Binding(); 25 binding2.ElementName = "titleco2"; 26 binding2.Path = new PropertyPath("Width"); 27 co2.SetBinding(ColumnDefinition.WidthProperty, binding2); 28 29 Binding binding3 = new Binding(); 30 binding3.ElementName = "titleco3"; 31 //设置源属性 32 binding3.Path = new PropertyPath("Width"); 33 //进行数据绑定 34 co3.SetBinding(ColumnDefinition.WidthProperty, binding3); 35 //将实例化的行和列添加到Grid中 36 grid.RowDefinitions.Add(row1); 37 grid.ColumnDefinitions.Add(co1); 38 grid.ColumnDefinitions.Add(co2); 39 grid.ColumnDefinitions.Add(co3); 40 grid.ColumnDefinitions.Add(co4); 41 grid.ColumnDefinitions.Add(co5); 42 grid.ColumnDefinitions.Add(co6); 43 grid.ColumnDefinitions.Add(co7); 44 grid.ColumnDefinitions.Add(co8); 45 46 //实例化需要的控件 47 CheckBox ckbChose = new CheckBox(); 48 ckbChose.Name = "Chose" + Entries.ToString(); 49 TextBox txtNumber = new TextBox(); 50 txtNumber.Name = "number" + Entries.ToString(); 51 ComboBox cmbProcedure = new ComboBox(); 52 cmbProcedure.Name = "cmbProcedure" + Entries.ToString(); 53 TextBox txtCompletion = new TextBox(); 54 txtCompletion.Name = "Completion" + Entries.ToString(); 55 TextBox txtDuration = new TextBox(); 56 txtDuration.Name = "Duration" + Entries.ToString(); 57 TextBox txtStartTime = new TextBox(); 58 txtStartTime.Name = "StartTime" + Entries.ToString(); 59 TextBox txtPredecessor = new TextBox(); 60 txtPredecessor.Name = "Predecessor" + Entries.ToString(); 61 TextBox txtResource = new TextBox(); 62 txtResource.Name = "Resource" + Entries.ToString(); 63 //将前面实例化的元素添加至Grid 64 grid.Children.Add(ckbChose); 65 grid.Children.Add(txtNumber); 66 grid.Children.Add(cmbProcedure); 67 grid.Children.Add(txtCompletion); 68 grid.Children.Add(txtDuration); 69 grid.Children.Add(txtStartTime); 70 grid.Children.Add(txtPredecessor); 71 grid.Children.Add(txtResource); 72 //添加后全部是堆积在第一行第一列,下面是对其进行排序 73 Grid.SetColumn(ckbChose, 0); 74 Grid.SetColumn(txtNumber, 1); 75 Grid.SetColumn(cmbProcedure, 2); 76 Grid.SetColumn(txtCompletion, 3); 77 Grid.SetColumn(txtDuration, 4); 78 Grid.SetColumn(txtStartTime, 5); 79 Grid.SetColumn(txtPredecessor, 6); 80 Grid.SetColumn(txtResource, 7); 81 return grid; 82 }
