在Silverlight没有像HTML中的table标签，如果我们想创建一个类似表格的界面或者说想创建一个类似Excel表格，那该如何创建呢，对于一般的可以使用DataGrid控件实现表格的显示，但是如果出现跨行跨列需要合并的表格，那DataGrid就无法实现了。接下来，我就介绍，如何使用Grid控件实现这样的功能。
首先，对于Gird布局控件，我们知道它有行和列的属性，以及可以在每行每列的单元格中放入控件。首先我们需要知道我们创建的表格有多少行或多少列，然后我们在动态创建行和列。
////// 创建Grid,实现表格的主体 /// protected void CreateGrid(int rows,int columns) { grid = new Grid() { Background = null, HorizontalAlignment = HorizontalAlignment.Stretch, VerticalAlignment = VerticalAlignment.Top, Margin = new Thickness(10, 0, 10, 0) }; for (int i = 0; i < rows; i++) { RowDefinition row = CreateRow(); grid.RowDefinitions.Add(row); } for (int i = 0; i < columns; i++) { ColumnDefinition column = CreateColumn(); grid.ColumnDefinitions.Add(column); } }
自定义创建行和列的方法：CreateRow()和CreateColumn()：
////// 创建表格的一行 /// ///返回Grid的一行 private RowDefinition CreateRow() { RowDefinition row = new RowDefinition() { Height = new GridLength(1, GridUnitType.Star) }; return row; } ////// 创建表格的一列 /// ///返回Grid的一列 private ColumnDefinition CreateColumn() { ColumnDefinition column = new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Star) }; return column; }
上面的代码，实现了一个表格的框架的创建，没有边框没有内容，接下来我们创建它的表头以及边框：
protected virtual void CreateHeader(ListheadList) { for (int i = 0; i < headList.Count; i++) { TextBlock block = CreateTextBlock(headList[i]); Border border = new Border() { Background = new SolidColorBrush(Colors.Transparent), BorderThickness = new Thickness(1, 1, 1, 1), BorderBrush = ConvertColor("FFC9CACA") }; border.Child = block; border.SetValue(Grid.RowProperty, 0); border.SetValue(Grid.ColumnProperty, i); grid.Children.Add(border); } }
创建Border是为了让单元格有边框，上面创建的Border的宽度为1Px，创建完后，你会发现最外层的边框宽度会细一些，中间内容的边框会粗一些，这是因为中间的部分是两个Border的宽度，如果要追求完美，你可以将表格最外层单元格的Border的宽度逐一设置一下。
创建TextBlock的方法，创建TextBlock主要是用来显示表格里面的内容：
////// 创建一个TextBlock控件 /// /// 控件的Text ///protected TextBlock CreateTextBlock(string text) { TextBlock block = new TextBlock() { Text = text, FontSize = 12, Foreground = new SolidColorBrush(Colors.Black), Margin = new Thickness(0, 5, 0, 5), TextWrapping = TextWrapping.Wrap, HorizontalAlignment = HorizontalAlignment.Center, VerticalAlignment = VerticalAlignment.Center }; return block; }
颜色转换的方法ConvertColor()：
////// 将ARGB颜色转化成系统的颜色 /// /// ARGB色彩的字符串 ///protected SolidColorBrush ConvertColor(string color) { SolidColorBrush brush; try { byte a, r, g, b; a = r = g = b = 255; r = Convert.ToByte(color.Substring(0, 2), 16); g = Convert.ToByte(color.Substring(2, 2), 16); b = Convert.ToByte(color.Substring(4, 2), 16); brush = new SolidColorBrush(Color.FromArgb(a, b, g, r)); return brush; } catch { return new SolidColorBrush(Colors.Black); } }
以上就完成了表格的表头的创建，下面介绍一下有关表头需要合并的操作：
////// 创建表格的表头 /// protected virtual void CreateHeaderOne() { TextBlock block; block=CreateTextBlock(headList[0]); Border border =new Border(){ Background=new SolidColorBrush(Colors.Transparent),BorderThickness=new Thickness(2,2,1,1) ,BorderBrush = ConvertColor("FFC9CACA")}; border.Child = block; border.SetValue(Grid.RowProperty,0); border.SetValue(Grid.ColumnProperty, 0); grid.Children.Add(border); block = CreateTextBlock(headList[1]); border = new Border() { Background = new SolidColorBrush(Colors.Transparent), BorderThickness = new Thickness(1, 2, 1, 1), BorderBrush = ConvertColor("FFC9CACA") }; border.Child = block; border.SetValue(Grid.RowProperty, 0); border.SetValue(Grid.ColumnProperty, 1); border.SetValue(Grid.ColumnSpanProperty, 2);//合并两列 grid.Children.Add(border); block = CreateTextBlock(headList[2]); border = new Border() { Background = new SolidColorBrush(Colors.Transparent), BorderThickness = new Thickness(1, 2, 1, 1), BorderBrush = ConvertColor("FFC9CACA") }; border.Child = block; border.SetValue(Grid.RowProperty, 0); border.SetValue(Grid.ColumnProperty, 3); border.SetValue(Grid.RowSpanProperty, 2);//合并两行 grid.Children.Add(border); }
表格内容的填充：
////// 将数据绑定到表格里 /// protected virtual void BindingContent() { int index = 1; foreach (var data in dataSource) { BindingOneColumn(index, data); index++; } } ////// 绑定一行数据 /// private void BindingOneColumn(int index,Model data) { TextBlock block; block=CreateTextBlock(data.ID.ToString()); Border border =new Border(){ Background=new SolidColorBrush(Colors.Transparent),BorderThickness=new Thickness(1,1,1,1) ,BorderBrush = ConvertColor("FFC9CACA")}; border.Child = block; border.SetValue(Grid.RowProperty,index); border.SetValue(Grid.ColumnProperty, 0); grid.Children.Add(border); string text = ConverterToString(data.Name); block = CreateTextBlock(text); border = new Border() { Background = new SolidColorBrush(Colors.Transparent), BorderThickness = new Thickness(1, 1, 1, 1), BorderBrush = ConvertColor("FFC9CACA") }; border.Child = block; border.SetValue(Grid.RowProperty, index); border.SetValue(Grid.ColumnProperty, 1); grid.Children.Add(border); text = ConverterToString(data.Sex); block = CreateTextBlock(text); border = new Border() { Background = new SolidColorBrush(Colors.Transparent), BorderThickness = new Thickness(1, 1, 1, 1), BorderBrush = ConvertColor("FFC9CACA") }; border.Child = block; border.SetValue(Grid.RowProperty, index); border.SetValue(Grid.ColumnProperty, 2); grid.Children.Add(border); text = ConverterToString(data.Age); block = CreateTextBlock(text); border = new Border() { Background = new SolidColorBrush(Colors.Transparent), BorderThickness = new Thickness(1, 1, 1, 1), BorderBrush = ConvertColor("FFC9CACA") }; border.Child = block; border.SetValue(Grid.RowProperty, index); border.SetValue(Grid.ColumnProperty, 3); grid.Children.Add(border); text = ConverterToString(data.Address); block = CreateTextBlock(text); border = new Border() { Background = new SolidColorBrush(Colors.Transparent), BorderThickness = new Thickness(1, 1, 1, 1), BorderBrush = ConvertColor("FFC9CACA") }; border.Child = block; border.SetValue(Grid.RowProperty, index); border.SetValue(Grid.ColumnProperty, 4); grid.Children.Add(border); }
以上代码实现了，将我们的数据集合循环添加到Gird的每一行，每一列中去。其中的dataSource是我们的数据集合，它是我们自定义类型Model的集合。
以上就完成了通过Grid控件实现Table的创建，效果图，如下所示：
