Format paragraphs

You can align text relative to the bounding boxes of the objects that contain the text in your Microsoft® Expression Blend™ application, for text that is contained within TextBox or RichTextBox objects. Specifically, you can align text to the left, right, or center, or you can justify the text to the left and right edges of the bounding box that contains the text. For RichTextBox objects, you can set the alignment of individual paragraphs separately, and you can also control the line height and paragraph spacing of text within the objects.

To align text within a TextBox or RichTextBox object

Select the TextBox or RichTextBox object that contains the text that you want to align, by using either the Selection tool or the Direct Selection tool.
In the Properties panel, under Text, click the Paragraph tab.
Set the Text Alignment as desired.

To set line height or paragraph spacing for text within a RichTextBox object

Select the RichTextBox object that contains the text that you want to format, by using either the Selection tool or the Direct Selection tool.
To format individual paragraphs separately within the text object, right-click the object, click Edit Text, and then click to place your cursor anywhere within the paragraph that you want to format. Otherwise, to uniformly format all paragraphs within the object, continue to the next step.
In the Properties panel, under Text, click the Paragraph tab, and then do one or more of the following:

Set the Line Height property as desired to set the amount of space between every pair of lines in the paragraph or paragraphs.
Set the Paragraph Spacing Before property to set the amount of space that precedes the paragraph or paragraphs.
Set Paragraph Spacing After to set the amount of space that follows the paragraph or paragraphs.
