In the LAN client Ryan wrote a great article on how to update and access controls across forms..

I have an insert page in the 8.1 web client which has two forms in the main section..

I'd like to have the second form either hide a control or update a control based on the actions of a control on the first form..

Do I need to deal in the workspace.. and how do I ensure I have the currently loaded 2nd form..?

This is usually handled in the web client by simply updating the properties of the bound entity. This is the rule in general for updating controls in forms in the web client. Instead of updating the control, you just update the bound entity properties. When the postback is done occurring the controls will reflect the values in the bound entity.

Thanks Ryan.. Basically what I am trying to do is change the properties of a control on the second form based upon values either entered by the user or changed by the user on the first form.

Trying to hide tabs on a multitab control on the second form based upon the value in a picklist on the first form without reloading the entire form since it could be an insert at the time..

If you set entity properties in one form, those will be available in the bound entity in other forms on that page. If you're wanting to pass values that aren't necessarily entity properties, you can use the page state. See http://customerfx.com/article/passing-values-between-forms-in-infor-crm-saleslogix-web/. Add items into the page state in one form and read them from the page state in another form. In the form you want to read them from (and hide tabs on the multitab control) just look for them in a LoadAction and make sure the LoadAction's Repaint Event is set to true so it executes on each page postback.
