How to make a table readonly dynamically

[former_member295881]

Hello Experts,

I've a requirement where I've to check certain values in a custom table and then based on those I need to make a table readonly at the run-time. I've been able to bind my table successfully but wondering if I can use any method or property to make my table read-only. Can somebody please advice how to accomplish it?

*binding
       lo_nd_rerate_dtl = wd_context->get_child_node( name = wd_this->wdctx_rerate_dtl ).
       lo_nd_rerate_dtl->bind_table( new_items = it_all_invoice_items  set_initial_elements = abap_true ).

Many thanks in advance.

Hi Zero,

The Table UI element has a readOnly property that you can bind to a context attribute or set statically in the view layout.

Thanks for your input Amy, so what will be the syntax? Can you give any example because I need to bind to my context attribute as I've to do it in the runtime after checking few values in some tables.

Hi Zero,

The Table's readOnly property is of type wdy_boolean. Assuming you have bound the property to a context attribute of the same type, you can use the code wizard to generate the code to set the context attribute value to true or false, for example...

   data lo_nd_mynode type ref to if_wd_context_node.
   data lo_el_mynode type ref to if_wd_context_element.
 
   lo_nd_mynode = wd_context->get_child_node( name = wd_this->wdctx_mynode ).
   lo_el_mynode = lo_nd_mynode->get_element( ).
 
   lo_el_mynode->set_attribute(
       name =  `BOOLEAN_ATTRIBUTE`
       value = abap_true ).

Cheers,

Amy

Take a new attribute"Read_only" of type wdy_boolean. Based on that condition set the attribute to abap_true if u want to make it read only.
