thanks for suggestion i just realized i can do that by js
yes actually my requirement is much simple if user clicks on space in the first instance of word i want to populate the cell from left one else i want render the date thing
in a either case if user click on space copy the value from left cell is populated else he would provide a text content like 25052019 which i can set the value as 25/05/1997
previously we were using our own framework modified version of GWT (Java) where i was reading the grid value on every onkeypress function
so if current key presscode equals to 32 i used to set text in current grid eventually we started migrating to JS and now we can not find any alternative to this functionality
