文本框的背景色部分

Question

I've been trying to set a background color to a part of a textblock. Since there is no function to this with in the TextBlock itself I figured I should be adding inlines.

However the inline objects (Run, Span, eg) have a private background field that gets its value from the parent TextBlock.

I figured I'd try to use an InlineUIContainer. Here is the code I used:

Grid grid = new Grid();
grid.Background = new SolidColorBrush(Colors.Red);
TextBlock block = new TextBlock();
block.Text = temp2;
grid.Children.Add(block);

InlineUIContainer iuic= new InlineUIContainer();
iuic.Child = grid;

Parent_TextBlock.Inlines.Add(iuic);

This last line gives an ArgumentException. Is there a way to change a part of a TextBlocks background color? If so, am I on the right track?

May be following option can helps you.

You can use RitchTextBox , since in WindowsPhone RitchTextBox is read only (as an TextBlock). My quick sample :) :

        <RichTextBox>
            <Paragraph>
                Some textSome textSome textSome textSome
                <Span Foreground="#FF0E0E0E">textSome textSome textSome</Span>
                textSome textSome textSome textSome textSome textSome textSome textSome textSome 
                textSome textSome textSome textSome textSome textSome textSome textSome textSome
                <InlineUIContainer> <!-- Look this -->
                    <Border Background="Blue">
                        <TextBlock Text="textSome textSome textSome textSome textSome textSome textSome textSome textSome textSome text"/>
                    </Border>
                </InlineUIContainer>
                textSome textSome textSome textSome textSome textSome textSome textSome textSome 
                textSome textSome textSome textSome textSome textSome textSome textSome textSome
            </Paragraph>
        </RichTextBox>

UPD #1 Do not forget about TextWrapping for Inline TextBlocks
