1、RadioButton 单选按钮

C#

1 2 3 4 5

void WriteText2(object sender, RoutedEventArgs e) {     RadioButton li = (sender as RadioButton);     txtb.Text = "You clicked " + li.Content.ToString() + "."; }

XAML

1 2 3 4 5 6

<StackPanel>     <RadioButton GroupName="colorgrp">Red</RadioButton>     <RadioButton GroupName="colorgrp">Blue</RadioButton> <RadioButton GroupName="numgrp">1</RadioButton>     <RadioButton GroupName="numgrp">2</RadioButton> </StackPanel>

2、Rectangle 实心矩形

3、RichTextBox 富文本输入框

XAML

1 2 3 4 5 6 7 8 9 10 11 12 13

<RichTextBox Name="richTB">   <FlowDocument>     <Paragraph>       <Run>Paragraph 1</Run>     </Paragraph>     <Paragraph>       <Run>Paragraph 2</Run>     </Paragraph>     <Paragraph>       <Run>Paragraph 3</Run>     </Paragraph>   </FlowDocument> </RichTextBox>

C#

1 2 3 4 5 6 7 8 9 10 11 12 13 14

StackPanel myStackPanel = new StackPanel(); // 创建一个FlowDocument来包含RichTextBox的内容。 FlowDocument myFlowDoc = new FlowDocument(); // 向FlowDocument添加段落。 myFlowDoc.Blocks.Add(new Paragraph(new Run("Paragraph 1"))); myFlowDoc.Blocks.Add(new Paragraph(new Run("Paragraph 2"))); myFlowDoc.Blocks.Add(new Paragraph(new Run("Paragraph 3"))); RichTextBox myRichTextBox = new RichTextBox(); // 向RichTextBox添加初始内容。 myRichTextBox.Document = myFlowDoc; //向StackPanel添加子集 myStackPanel.Children.Add(myRichTextBox); //设置页面内容为StackPanel this.Content = myStackPanel;

4、ScrollBar 滚动条。没见过单独用的，一般都直接再外面套一个ScrollViewer

5、ScrollViewer 带滚动条的容器。
