Hi Dhiraj,

You can make use of attributes to govern the behaviour of your UI element. Just bind the property attributes of UI element to the context node attributes via which you want to control the behaviour and then control the UI element by attribute values through coding .

Hope this helps.

Hi Dhiraj,

Just for the sake of example we will try to govern the behaviour of "Expand/Collapse or Open/Close" property of Tray UI element. For this follow the steps mentioned:

1) Create a attribute, open_close, of type Boolean in your view context

2) Go to Property table of Tray UI element and then click on the button which is present next to Expanded.

3) Create a button and label it as say "Open/Close" and in the OnAction write a mehtod name say "Open_Close_Tray".

4) In this method insert code which will set the attribute "open_close" value to abap_true or abap_false depending on the current value ..

In a similar manner you can govern the behaviour of rest of the property attributes of Tray UI element as well.

Hope this helps. If this post was of any use do award points.

Hi Dhiraj,

I hope you do know how to use the WD Wizard .. its the thing on top with a torch light symbol .. click on it and then select the radio button with "read context" and then chose the context attribute .. once u have done this replace the Get_attribute method with Set_attribute .. for tht just do the changes i suggest ..

1) rename the method

2) remove the importing and exporting TEXT .. but not the variables and attribute name ..

3) now pass abap_true or abap_false to your "value" parameter ..

By the way Dhiraj there are a few threads that you opened and the query i am sure has been answered but you havent closed the thread .. I would request you to close those threads as well and award points to the posts tht deserve ..

Thanks and regards,

Anoop
