How to add custom lookup method to the datasource field in form?

Posted on by Shooowtek 843
Hi,
Can anyone suggest how to add a custom lookup to datasource field in form?
It is known that I could do it through event handler on the form control, but users often personalize the form view for themselves, and so event handler will not work here.
 
 
Thanks.

    I created an extension, but unfortunately it does not work. Can anyone help?
     
    [ExtensionOf(formDataFieldStr(SalesTable, SalesLine, MyField))]
final class SalesTable_SalesLine_MyField_Extension
{
    public void lookup(FormControl _formControl, str _filterStr)
    {
        
        next lookup(_formControl, _filterStr);
        
        info("Custom lookup OK");
    }
}

    Hi Shooowtek,
     
    It's not recommended approach to write COC for lookup method.
    If you write COC for lookup method - I guess the lookup will call two times - One from the next keyword and other from the code you have written lookup for - Mostly it will throw error. Only way will be through event handler only.
     
    Thanks,
    Girish S.

    Hi, May I know what's the issue if user personalizes the form?

    Hello. Thank you for your reply.
     
    The event handler is for a specific control in the forms. In case the user personalizes his grid, this will not work because the form control contains SysGen....
     
    That's why I'm looking for another solution.
     
    Thanks.

    You can use event handler which is simply a single method. But with COC, you need to override 2 methods I remember. Using event handler, you can event stop standard lookup execution too.
