Height of input box for Blob Field

(1) ShareShare

Posted on by Nick Webb 911

In an AL extension, is there a way to increase the height of an input box when a multi-line text blob field is displayed on a custom Business Central page? (see field below highlighted in yellow). At the moment it appears to be fixed to show 3 lines with scrollbars.

    Hi, Unfortunately, as far as I know, there is currently no good way to expand the height, except using Control Add-In Object.

    More details: https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/devenv-control-addin-object

    PS: You can expect Microsoft to bring the text editor in Send Email page to any page.

    Thanks.

    I found this Control Add-In tutorial, which is helpful:-

    Quick question: Rather than create a completely new user-control, can Control Add-Ins be used to edit Html attributes that are already there? (e.g.) If there are any textarea elements on the page with rows="3" I'd like to change them to rows="6" for instance? I know this can be done in javascript ( (i.e.) document.getElementsByTagName('textarea') ) but can it be done using a Control Add-In?
