ASP.NET - Enter disabled on form prevents enter (new line) in multiline textbox

help you fix your problem Simply don't disable "form enter" using the form keypress event.
If there is more than one input/control, browsers shouldn't "submit on enter", but rather only when enter is pressed while a submit button is focused .. (which means you can use a similar approach to disable enter on the submit button or make it unfocusable in such cases).
if ((event.target || event.srcElement).nodeName != "TEXTAREA") {
   // not textarea (multi-line input), suppress as original
}

Setting GHCi prompt inside multiline blocks

may help you . In GHC 7.8.1 and newer, you can change the continuation prompt using :set prompt2.
See GHC #7509.

.NET Multiline Textbox Make Shift+Enter working instead of Enter key

I hope this helps . you'll need to override OnKeyDown and check for enter key using the KeyDownEvent's KeyCode property.
If enter was pressed and the keydownevent's modifiers property does not equal Keys.Shift you'll need to suppress the key press. Here's the documentation on how to do that:

Getting Multiline haskell function to work in ghci

hope this fix your issue I created this haskell function to remove odd numbers from a list and was trying in ghci. I keep getting the error below though I have enabled the multiline mode and used 4 spaces for indentation. , Your if statement needs to be indented at least one more space:
Prelude> let removeOdds nums =
Prelude|      if null nums

Complete example:

Prelude> let removeOdds nums =
Prelude|      if null nums
Prelude|      then []
Prelude|      else
Prelude|          if (mod (head nums) 2) == 0
Prelude|          then (head nums) : (removeOdds(tail nums))
Prelude|          else removeOdds(tail nums)
Prelude|
