Hi Akshay, I understand that ur unable to get the handle of the item renderer on whom the focus has to be set. Thats why I suggested dispatching a custom event that is specific to the textfield on whom the focus needs to be set. Let me explain my suggestion again.
Consider the scenario where I have 3 dynamic columns in my datagrid. Now the focus is on the 3rd textfield of either the 1st or 2nd column. The minute the user presses TAB, an event (evt1) will be dispatched. In the listener function for evt1 u analyze which column has actually dispatched the event. Based on the source of the event, u dispatch another event evt2 for column 2 or evt3 for column 3. Every 1st textfield in the columns will have a listener corresponding to a particular event. For eg my column 2 textfield will respond only to evt2 & column 3 textfield will respond only to evt3. Since this event listner will be written directly in the file where the renderer code has been written, u wont need the handle of the renderer. You will be able to directly access the textfield from the listener function. When the evt2 is caught u just set focus to the 1st textfield of column 2 and incase of evt3 u set focus to the 1st textfield of column 3. This is what i meant by "Since the event will be unique only one textfield will respond to that". What I understand from ur post is that u are trying to directly assign focus to the corresponding textfield after the tab event which will be difficult since I am unaware how to get the handle for the item renderer from the outside. I think u cannot assign an id for the item renderer so it will be difficult to access the inner textfields from the outside. Also note that this is the crudest way possible of coding this scenario but it should resolve ur problem.
