Working on a custom validator for a dataGrid itemEditor. Have 2 questions:
- Is there a way to prevent loosing focus while validation fails. I know I could handle the itemEditEnd event and use event.preventDefault() to disallow ending the edit, but I would prefer to do this at the DataGridColumn level and not on DataGrid level - together with the itemEditor validation.
- Similarily I would like to hook in before the edit begins and do some checks and possibly prevent the edit, from within the itemEditor. Again, I know I can use itemEditBegin and Beginning on a DataGrid level, but I would prefer this on GridColumn level. I have played with calling a function from the itemEditor (code in the creationComplete handler)...something like:
if ( ! canWeEditThisItem(this.data))
parentDocument.dg.destroyItemEditor();
It works but I am a bit cautious because basically the itemEditor is "committing suicide". Could create some memory problems or what have you... Has anyone done something similar? Any recommendations on a good practise?
Thanks a bunch
