Thank you Tony. I corrected my error. There were 2 bugs.

1. I forgot that it is case sensitive. becoz I used 'editurl' and it did not work.

after I changed to editUrl it started to work.

2. As you said, I am trying both the options editUrl and CellEdit. Both of

them are working great.

Thank you for your quick response and great plugin.

Now i am working on search bar and SubGrid.

GO.
