I have a grid with input fields and buttons that is dynamically populated from the DB (so, there are variable number of rows). Here is what I need to do: when a user clicks on an input field, I want a button on that particular row to be made visible. In the someInput.Click() javascript, how do I get the index of the particular row? Correspondingly for the Appery('someButton').show() how do I specify which row button needs to be shown?
