Multiline for WPF TextBox
I am developing an app for sending some feedback.
Basically I'm trying to make a
TextBox for comments, but I'm used to the WinForms
MultiLine=true. I've set
MinLines to 3, which is getting there, but preferably I'd like it if the user is able to type wherever in this block - like press enter and do dot points sort of thing. For example:
- Item 1 blah - Item 2 blahlb lahbvl d
But at the moment the text all stays on one line.
- Item 1 blah - Item 2 blahb blahb blah
These comments will then help fill the body of an email which is sent. It may be pointless if I can't easily keep the same formatting when putting this string into the email body string (so that it looks like it does when sent as it does when typed).

Also, if, like me, you add controls directly in XAML (not using the editor), you might get frustrated that it won't stretch to the available height, even after setting those two properties.
To make the TextBox stretch, set the
In retrospect, I think this must have been necessary thanks to a default style for TextBoxes specifying the height to some standard for the application somewhere in the App resources. It may be worthwhile checking this if this helped you.
Here is the sample
XAML that will allow
TextBox to accept multiline text and it uses it's own Scrollbars:
<TextBox Height="200" Width="500" TextWrapping="Wrap" AcceptsReturn="True" HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Auto"/>
Contrary to @Andre Luus, setting
Height="Auto" will not make the
TextBox stretch. The solution I found was to set
The only property corresponding in WPF to the
TextBox.Multiline = true
is the WPF property:
TextBox.AcceptsReturn = true.
<TextBox AcceptsReturn="True" ...... />
All other settings, such as
WordWrap etc., only control how the TextBox interacts in the UI but does not affect the
