As an alternative to the other two solutions, you could use TextTrimming="WordEllipsis" in the XAML, it just depends on whether you want to limit the string to a certain number of characaters or let the trimming occur based on textbox size.

I used the following code to truncate strings when I needed some simple text logging. Might be an inspiration. 

public static string Truncate(this string yourString, int maxLength)
{
    return yourString.Substring(0, Math.Min(maxLength, yourString.Length));
}

Reviewing Yair Nevet's answer I find his take on the problem more complete. You can use the code above similarly to his answer:

string yourString = "Your long text goes here".Truncate(10);

Given the desired text string and the maximum characters length of your text-box, use this extension method to solve it:

public static string TruncateAtWord(this string input, int length)
{
    if (input == null || input.Length < length)
        return input;

    int iNextSpace = input.LastIndexOf(" ", length);

    return string.Format("{0}...", input.Substring(0, (iNextSpace > 0) ? iNextSpace : length).Trim());
}

Usage:

var ellipsisedString = "this is a very long string and I want to cut it with ellipsis!".TruncateAtWord(25);

Result:

"this is a very long..."
