Hi Santosh.

Yes you can add checkboxes at runtime. This can be done in the method

wddomodifyview:

 method WDDOMODIFYVIEW .

data: LR_CONTAINER         type ref to CL_WD_UIELEMENT_CONTAINER,
        LR_CHECKBOX            type ref to CL_WD_CHECKBOX,
        LR_FLOW_DATA         type ref to CL_WD_FLOW_DATA.

 LR_CHECKBOX           =  CL_WD_CHECKBOX=>NEW_CHECKBOX( ).
 LR_FLOW_DATA        =  CL_WD_FLOW_DATA=>NEW_FLOW_DATA( element = LR_CHECKBOX ).
 LR_CONTAINER ?= view->GET_ELEMENT( 'ROOTUIELEMENTCONTAINER' ).
 LR_CONTAINER->ADD_CHILD( LR_BUTTON ).

endmethod.

For mor info check out the <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/11/ba74412cba127de10000000a155106/content.htm">help site</a>.

Generally you should consider that dynamically adding UI elements lower the

maintainability of the application.

Hope this helps,

Cheers

P.S: WDDOMODIFYVIEW has the parameter first_time which

indicates whether the method is called the first time.

Keep in mind that the method is called each roundtrip.

Hi santhosh ,

Yes Of course you can add Checkboxes dynamically .

Basically It is not just about checkbox , one can add any UI element dynamically .May you can add button or change the layout with Dynamic programming .

another thing you need to write code on OnWDModifyView Because you are adding something dynamically on change of same view .
