RichTextBox.ContentEnd Property

Silverlight

Gets a TextPointer that indicates the end of content in the RichTextBox.

Namespace: System.Windows.Controls
Assembly: System.Windows (in System.Windows.dll)

Copy

public TextPointer ContentEnd { get; }

Property Value

Type: System.Windows.Documents.TextPointer
A TextPointer that indicates the end of content in the RichTextBox.

Remarks

In an empty RichTextBox (one without blocks), ContentEnd is the same as ContentStart, and both are insertion positions. This is the only instance when ContentStart or ContentEnd is an insertion position.

Examples

The following method uses the ContentStart and ContentEnd methods to determine if a RichTextBox is empty.

Copy


//This method returns true if the RichTextBox is empty.
public bool isRichTextBoxEmpty()
{
    TextPointer startPointer = MyRTB1.ContentStart.GetNextInsertionPosition(LogicalDirection.Forward);
    TextPointer endPointer = MyRTB1.ContentEnd.GetNextInsertionPosition(LogicalDirection.Backward);
    if (startPointer.CompareTo(endPointer) == 0)
        return true;
    else
        return false;
}
