Hi, can someone share an example to:

set a minimum value for a field
with a set focus back on the field if they try to save
and an on save event that will prevent the form from being saved

I have the field set to allow for 12 characters and I need the value to validate that there are 12 characters.

Dynamics 2016 on-prem.

Thank you in advance!

Hi kmc333,

Here you go. Add the below method on change of your field. Do remember to update the schma name of your field. The below script I used for the account name field.

===================

function checkNameLength()

{

var currentName = Xrm.Page.getAttribute("name").getValue();

if(currentName.length <20)

{

Xrm.Page.getControl("name").setNotification("Field length should be 20 characters");

}

else

{

Xrm.Page.getControl("name").clearNotification();

}

}

============================

I hope this helps. If my post answers your questions, please mark it helpful/ verified.

Hi Ravi, I have something similar in place which works to set the alert to be sure to have the correct length to the user but I can't get the focus to set back on the field and also prevent the save from occurring. Essentially the user can still save the form without setting the field properly with the amount of characters I need.

The above script doesn't give you an alert instead it will set the field notification with the * mark and then you won't be able to save the recor dunless that field error is fixed.

Try the above script and let me know how it goes.

Hi,

Just to add what has not yet been answered:

Xrm.Page.getControl(“controlname”).setFocus();

Take a look at the following blog post:

community.dynamics.com/.../crm-2015-how-to-set-focus-in-javascript

For preventing to save a form, see the following post:

Hope this helps.
