I am new to extjs 4 and I have got a problem to customize the grid panel. My application have JSON data to render in a grid. After populate the data when user click on a particular row he need to get an panel (Just like row editing plugin) of a textfield and a button to send the entered text to server through the controller. This data that user entered is not the data of grid column.
I need to know is it possible? And if it is, then how can I make it.
Thanks in advance.
Sure it is possible. First look at the following example from the Extjs 4.1 docs
All you need is to add your listener to itemclick grid event. Within this listener function you can create panel you need.
