# How to: Manipulate Flow Content Elements through the Inlines Property
|
|
These examples demonstrate some of the more common operations that can be performed on inline flow content elements (and containers of such elements, such as <xref:System.Windows.Controls.TextBlock>) through the **Inlines** property. This property is used to add and remove items from <xref:System.Windows.Documents.InlineCollection>. Flow content elements that feature an **Inlines** property include:
|
|
|
|
- <xref:System.Windows.Documents.Bold>
|
|
|
|
- <xref:System.Windows.Documents.Hyperlink>
|
|
|
|
- <xref:System.Windows.Documents.Italic>
|
|
|
|
- <xref:System.Windows.Documents.Paragraph>
|
|
|
|
- <xref:System.Windows.Documents.Span>
|
|
|
|
- <xref:System.Windows.Documents.Underline>
|
|
|
|
These examples happen to use <xref:System.Windows.Documents.Span> as the flow content element, but these techniques are applicable to all elements or controls that host an <xref:System.Windows.Documents.InlineCollection> collection.
|
|
|
|
## Example
|
|
The following example creates a new <xref:System.Windows.Documents.Span> object, and then uses the **Add** method to add two text runs as content children of the <xref:System.Windows.Documents.Span>.
|
|
|
|
[!code-csharp[SpanSnippets#_SpanInlinesAdd](~/samples/snippets/csharp/VS_Snippets_Wpf/SpanSnippets/CSharp/Window1.xaml.cs#_spaninlinesadd)]
|
|
[!code-vb[SpanSnippets#_SpanInlinesAdd](~/samples/snippets/visualbasic/VS_Snippets_Wpf/SpanSnippets/visualbasic/window1.xaml.vb#_spaninlinesadd)]
|
|
|
|
## Example
|
|
The following example creates a new <xref:System.Windows.Documents.Run> element and inserts it at the beginning of the <xref:System.Windows.Documents.Span>.
|
|
|
|
[!code-csharp[SpanSnippets#_SpanInlinesInsert](~/samples/snippets/csharp/VS_Snippets_Wpf/SpanSnippets/CSharp/Window1.xaml.cs#_spaninlinesinsert)]
|
|
[!code-vb[SpanSnippets#_SpanInlinesInsert](~/samples/snippets/visualbasic/VS_Snippets_Wpf/SpanSnippets/visualbasic/window1.xaml.vb#_spaninlinesinsert)]
|
|
|
|
## Example
|
|
The following example gets the number of top-level <xref:System.Windows.Documents.Inline> elements contained in the <xref:System.Windows.Documents.Span>.
|
|
|
|
[!code-csharp[SpanSnippets#_SpanInlinesCount](~/samples/snippets/csharp/VS_Snippets_Wpf/SpanSnippets/CSharp/Window1.xaml.cs#_spaninlinescount)]
|
|
[!code-vb[SpanSnippets#_SpanInlinesCount](~/samples/snippets/visualbasic/VS_Snippets_Wpf/SpanSnippets/visualbasic/window1.xaml.vb#_spaninlinescount)]
|
|
|
|
## Example
|
|
The following example deletes the last <xref:System.Windows.Documents.Inline> element in the <xref:System.Windows.Documents.Span>.
|
|
|
|
[!code-csharp[SpanSnippets#_SpanInlinesRemoveLast](~/samples/snippets/csharp/VS_Snippets_Wpf/SpanSnippets/CSharp/Window1.xaml.cs#_spaninlinesremovelast)]
|
|
[!code-vb[SpanSnippets#_SpanInlinesRemoveLast](~/samples/snippets/visualbasic/VS_Snippets_Wpf/SpanSnippets/visualbasic/window1.xaml.vb#_spaninlinesremovelast)]
|
|
|
|
## Example
|
|
The following example clears all of the contents (<xref:System.Windows.Documents.Inline> elements) from the <xref:System.Windows.Documents.Span>.
|
|
|
|
[!code-csharp[SpanSnippets#_SpanInlinesClear](~/samples/snippets/csharp/VS_Snippets_Wpf/SpanSnippets/CSharp/Window1.xaml.cs#_spaninlinesclear)]
|
|
[!code-vb[SpanSnippets#_SpanInlinesClear](~/samples/snippets/visualbasic/VS_Snippets_Wpf/SpanSnippets/visualbasic/window1.xaml.vb#_spaninlinesclear)]
