Hi,

I've a strange problem in the field events. To find a solution I created a small projet in ASPRunner.net 10.7 (Build 39273 x64).

First I created a new handler "StringResultatVisite_Event" for the change event.

  1. Client before (nothing)
  2. Server (nothing)
  3. Client after

var ctlTest = ctrl.getPeer('txtNoVisit');
ctlTest.setValue( 100 );

(the control (field) txtNoVisit exist in the list with "Spreadsheet mode" activated

Unfortunately all my tests result in an error
Uncaught TypeError: Cannot read properties of undefined (reading 'setValue')

Thanks for any help!

It looks like it should work but it is hard to tell without having access to your project.

Did you test it on a regular Add or Edit page?

Hi,

Unfortunately the same problem on regular Add or Edit page!

Definitely works in the test project. You might be doing something wrong or different. The error message itself suggests that field 'txtNoVisit' doesn't exist on that page or is not spelled correctly.

Hi

By "The error message itself suggests that field 'txtNoVisit' doesn't exist on that page or is not spelled correctly." do you mean the "database field name" or the "id name"?

Yves

Update: ahhhhhh it's the database field name! :-)

There is no such thing as "id name". ID is ID, and name is a name. Javascript Control API works with database field names.
