Hello Hemalatha msk
Answer 1) Regarding the list, you must be using a service to populate the data in the list. Map the 'Selected Rows Changed' event of that service and bind it to the service that you want to be invoked on row selection. For this click on the service which is populating data and you will see the corresponding 'Selected Rows Changed' event in the bottom right section of the screen. Bind this event with the service to be invoked by drag and drop.
Answer 2) For text box you need to bind the change event of text box with that particular service. Click the left side of Text box and drag the change event to service.
Regards,
