After creating a Mult Lines of Text field, how to write a JavaScript in such a way that while entering the text in the field, when we reach certain point (say some length of 15 or 20) the line should be break and start at next line?

To these type of events we can use key press methods that helps to make actions dynamically when we entering the keys itself.

Hi Shahbaaz,

Actually my requirement is not that. I want the way that when we entering the keys/letters/characters in the field, it should dynamically get into new line when certain key length is reached. Hope you understand the requirement. For that we need to use "keypress" methods in MS CRM. You can find the theory here: msdn.microsoft.com/.../gg334266.aspx methods

If you get the code by using that method, please share me.

Thanks for reply!

Hi Korada,

You can try below java script code on change of your field(Multi line text).

Note : it will trigger on change of field,means once you complete full sentence then only it will break the sentence in new line.

function enterNewLine(context)
{

var getDescriptionContext = context.getEventSource();
if (getDescriptionContext.getValue() != null) {
var TempValue = getDescriptionContext.getValue()
try {
var newValue="";
for(var i=0;i<TempValue.length;i++)
{
newValue += TempValue.charAt(i);
if (i%10 == 0 && i != 0) // check after how many char you want new line
{
newValue +="\n";
}
}
Xrm.Page.getAttribute("description").setValue(newValue);
}
catch (e) {
}
}
}

Also you need to pass the context on the field change event like below screenshot,

In my example i have used new line after 10 char you can change that in the above code in if (i%10 == 0 && i != 0) condidtion.

If you find it helpful, Please mark my answer as Verified

If you still have any issue, please let me know.

Best Regards,

Shahbaaz

Please refer msdn.microsoft.com/.../gg334481.aspx

Here you can see all the supported events on which you can trigger your code. For your requirement, you would need to execute the code every time a character is typed on keyboard; the javascript event for that is "onkeypress"; unfortunately crm does not support writing script on this event.

So I am sure that executing any script on "onkeypress" is not recommended by Microsoft as the script may break in future updates of the product.

Thanks Mayank! But, are you sure about developing that code is impossible and not recomended?

there is no documented way of achieving this. you may achieve this by some unsupported lines of code, although that is not recommended.

supported way would be to develop a custom control using a HTML web resource & programming the "onkeypress" event

www.w3schools.com/.../event_onkeypress.asp

Hope this helps.
