Dyanmic messages in MessageToastshow

hi ui5 guys,

i am having an Split App master-page contains the Standard List Items.

when i select the one of the item ,then corresponding item details has to show on detail page with message .

for example if i select the product id item at left pane the right side pane should display the corresponding product details in SimpleForm with messageToast.show () as "<so and so product> is Displayed successfully" message .

hear i am wondering how to Display the Dynamic message With MessageToast.show()
