在Windows应用商店的RichEditBox中插入列表
我基于RichEditBox控件为Windows应用商店(WinRT)开发文本编辑器. RichEditBox将ITextParagraphFormat用于段落操作,将ListAlignment,ListLevelIndex和其他属性用于项目符号列表和编号列表. 我没有找到任何将项目符号或编号列表插入RichEditBox的示例. 如何使用ITextParagraphFormat将列表添加到RichEditBox?
I develop text editor for the Windows store application (WinRT) based on RichEditBox control. RichEditBox use ITextParagraphFormat for paragraph operation and ListAlignment, ListLevelIndex and other properties for bulleted and numbered lists. I not found any samples to insert bulleted or numbered lists to RichEditBox. How I can to add lists to RichEditBox using ITextParagraphFormat?
您需要设置 MarkerType 枚举以选择所需的其他列表类型.
You need to set the ITextParagraphFormat.ListType property for the ITextParagraphFormat. For bullet, set the ListType property to MarkerType.Bullet
, for number, set the ListType to MarkerType.Arabic
. More types please reference the MarkerType enumeration to choose other list types you want.
这里是有关将项目符号和编号添加到可以测试的RichEditBox中的选定段落列表中的示例.
Here is a sample about adding the bullet and number to the selected paragraph list in the RichEditBox you can test.
XAML代码
<RichEditBox x:Name="Richbox" Height="400" Margin="40" >
</RichEditBox>
<Button x:Name="BtnSetbullet" Content="set bullet to richeditbox" Click="BtnSetbullet_Click"></Button>
<Button x:Name="BtnSetNumber" Content="set number to richeditbox" Click="BtnSetNumber_Click"></Button>
后面的代码
private void BtnSetbullet_Click(object sender, RoutedEventArgs e)
{
Windows.UI.Text.ITextSelection selectedText = Richbox.Document.Selection;
ITextParagraphFormat paragraphFormatting = selectedText.ParagraphFormat;
paragraphFormatting.ListType = MarkerType.Bullet;
selectedText.ParagraphFormat = paragraphFormatting;
}
private void BtnSetNumber_Click(object sender, RoutedEventArgs e)
{
Windows.UI.Text.ITextSelection selectedText = Richbox.Document.Selection;
ITextParagraphFormat paragraphFormatting = selectedText.ParagraphFormat;
paragraphFormatting.ListType = MarkerType.Arabic;
selectedText.ParagraphFormat = paragraphFormatting;
}
