WPF使用后台C#代码创建Grid

来源:转载


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Grid64 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 }
