[CLOSED] Cell Editor navigation in a Grid
Using the ideas presented in this post (http://forums.ext.net/showthread.php?21924) I created a grid with locking columns and a highlighted selected row that would allow the user to move between the editor between cells using up, down, enter, tab, shift+enter, and shift+tab. basically making my grid act like a Excel spreadsheet.
As soon as I did that the newly focused cell stopped going into "edit" mode until I hit the enter key a second time.
To make matters worse, adding the following property (which was the reason I was updating to the latest build) causes my navigation code to fail completely -- unless the user changes the value of the cell/field.
Since the IgnoreNoChange property was the main reason to update to the latest build, I am going to pull it and roll back to the 2.2 version for now but with 2.3 around the corner I really need to know how to deal with the upcoming changes.
Thanks in advance for your help and insight.
