Reference an object in a superclass
Hi, I have created a dataGrid object in the superclass of a jsMainForm. How do I get the reference to this dataGrid object? I have a method $getRef in the dataGrid with “Quit method $cinst.objs.dataGrid”. If I call this method in a $cfield, the return value references to the mainForm instead of referencing the superform.
Any help is appreciated.

Hi Martin,
There is no difference in the instance if the code is in the inherited form or in its superclass. The instance is the same.
Maybe I understand this wrongly. What exactly do you get back when you debug the code and look at the item reference variable?
Best,
Andreas

Please see the attached screenshot of the returned reference. The jsChildDataListCustomReport inherits from a parentForm. If I run “Calculate <b style=”font-family: inherit; font-size: inherit; color: var(–bb-body-text-color);”>designcol as <b style=”font-family: inherit; font-size: inherit; color: var(–bb-body-text-color);”>pQueryDataGridRef.$designcols” I get 1 which is wrong.

Hi Martin,
I do not see anything wrong in the reference. It points to the grid component in the instance.
However $designcols is a property that is not accessible in the instance. That is why it is called $designcols.

Aha! I see where I am drifting off. The property insight is a pointer in the right direction. Thank you.

But why I am unable to get the property of an object’s $designcols? I am able to get other properties such as name.

Reading properties might only be possible in client methods. You may be able to read $name or $id from a server side method but some code might have changed a color on the client, so how would the server read such a property.
Therefore this can only be done from a client executed method.
