Question

The width of Tab (\t) character in silverlight TextBox is not equal to 4 spaces or 8 spaces. It’s too short.
Is it possible to change the width of the TAB (\t) character displayed in a silverlight TextBox?

Note that I want to avoid replacing TABs with spaces.
Any ideas on how to do this?

Answer 1

Silverlight does not allow you to change the tab character length in a TextBox.

If your reading in a string (from a file or something) and setting the Text to it then if you look at your Text Property you’ll see the escaped tab (\t). Searching for a \t is easy

TabTextBox.Text = TabTextBox.Text.Replace("\t", "    ");

So this will replace all tabs with 4 spaces.

Besides pressing tab in a TextBox will not tab the text. It will focus to the next UIElement within the parent UIElement.
