Disable Save Button Until User Chooses an Item in Drop Down and Signs Signature Card

[pbc83]

I have a situation where I want to disable the Save button until the user completes 2 fields. One is simple enough, it's a dropdown selection. The second is a signature panel that needs to be signed by the user. How do I go about achieving this? I thought of using a 'Client Side Enable Expression' on the Save button's properties, as illustrated in my attachment, but it doesn't seem to work with the 'MaterialAcceptanceSignature' field (which is my signature control). Any ideas?

Thanks!

You could add a hidden unbound text control on your UX called "HasSignature" and in the Client side event OnSignatureCaptureAccept set the value of this control to "Y" or some other value. In your client side enable expression for your save button test the value of the HasSignature field to see if it is "Y".

Thanks for the suggestion.

Sounds like a great idea, Brad, but is there a client side event called 'OnSignatureCaptureAccept' ? I'm not so sure.

If you go into the client side events and type "signature" in the filter you'll see it. It was added in one of the preview releases a couple of months ago in response to an issue I had of needing to be able to record a geolocation at the time that a signature was accepted even if the record wasn't saved at that moment.

I added {dialog.Object}.setValue('HasSignature','True'); to the onChange event of the MaterialAcceptance signature control. However, when the user clicks on the 'Sign' button, then signs and then presses the 'Accept' button, the javascript code that is supposed to change the 'HasSignature' field to 'True' does NOT fire.

However, if the user clicks on the field area where the signature card will appear before clicking on the 'Sign' button, the onChange event fires. This is wierd and I can't expect the user to click in that area before hitting the 'Sign' button. Any idea why this is happening? Why aren't there events associated with the buttons of the signature control?

See screenshots for illustration.

Brad,

I'm sorry I didn't see your latest message. You are the man! Yes, indeed that 'onSignatureCaptureAccept' event was 'hiding' in the client-side events list on the left. I'm still not very used to Alpha's unique geography of events, controls and everything in between!

Now everything works as planned. Thank you very much for your invaluable assistance!

Hi Peter,
What I do in this same situation is use a toggle

First create a hidden, unbound, numeric control with a default value of zero and call it "toggle"
Then, In the OnChange event of each pulldown use this inline javascript:

var total = {dialog.Object}.getValue('TOGGLE');
total == total + 1;
{dialog.Object}.setValue('TOGGLE', total);

Next, on your button's "Enable Expression" property use: toggle = 2

Hope that helped.
