Event to capture on click of "OK" in Search Help

Hi,

I have an input field with search help.

Used SET_ATTRIBUTE_VALUE_SET method of IF_WD_CONTEXT_NODE_INFO to bind the Search help values.

I need to perform some operation when the user clicks on "OK" of the search help.

I don't want to use OVS or write the code in WDMODIFYVIEW method.

Is there any possible way to handle this.

Version - SAP NetWeaver 7.3

Please help.

Regards,

Sujay.
