Fairly easy to do.

The drop down control has an event called 'onSelect'. Create an action and assign that event property to the created action. In the action, you can put whatever code you like.

For your problem perhaps binding the table visibility to a context attribute and then setting that attribute value to if_wdl_core=>visibility_visible or if_wdl_core=>visibility_none based on input might do the trick.

There are quite a few ways you could do this, but the most important detail for you to resolve is setting up the event handler for the drop down control.

HI

While the user clicks on the drop down then only the table should be displayed else it should not be displayed ( It should be displayed drop down only ). If we can do this in setttings, Kindly explain me where to do and what to do?

Thank you for your Quick responds.

Hi Indiaran,

You want to display Table when select value from dropdown right??

Create Transparent Container and place your table in TC.

Create one attribute say VISIBILE of type WDUI_VISIBILITY and bind this attribute to Transparent containers visible property.

And in onaction of Dropdown use set_attribute.

* set single attribute
      lo_el_context->set_attribute(
           name =  `VISIBLE`
           value = '2' ).  // 2 for visible, 0 - none.

Cheers,

Kris.

Hello Indiranjithn,

in which context node did you create the attribute. Did you create it directly under the CONTEXT node (Root node)? if so then you need to get the context element of this node and then call set_attribute

data lo_el_root type ref to if_wd_context_element.
lo_el_root = wd_context->get_element( ).
lo_el_root->set_attribute(
name = <NAME OF THE CONTEXT_ATTRIBUTE IN UPPER CASE>
value = '2' ). 2 for visible, 0 - none.

Hi,

Create attribute under view context. attribute name 'VISIBILE' of type WDUI_VISIBILITY.

and add this code to your dropdown onaction.

DATA lo_el_context TYPE REF TO if_wd_context_element.
      DATA ls_context TYPE wd_this->Element_context.
      DATA lv_visible TYPE wd_this->Element_context-visible.

* get element via lead selection
      lo_el_context = wd_context->get_element( ).

* set single attribute
      lo_el_context->set_attribute(
           name =  `VISIBLE`
           value = '2' ). // 0 - for none

Cheers,

Kris.
