title: Adding filter in Janus Gridex
body: <p>I am using a Janus GridEX with multiple columns. I want to apply filter in gridex data based upon input value for a particular column in GridEX . I am trying to add an extra row at the top where i can input filter condition in a textbox for a particular column. I want to keep only the filter cells as editable while keeping rest of GridEX non editable. If it is non possible, then can I use FilterEditor to implement the same.?</p>
