This is Part 1 of a new series covering item Editors, which allow data to be changed directly inside of a list control.This first article covers inline item Editors, which are very simple, though quite useful, components you write directly inside your MXML files.say in that Value Column should be clicked and then that particular cell alone should be edited. You may have tried to select a row in a Data Grid in WPF programmatically by setting its Selected Item property or Selected Index property only to find out that doing this doesn’t result in the exact same behaviour as when you select a row by clicking on it with the mouse.I recently completed a series on item Renderers ― customizations to list controls that format the display of the list contents.

The grid is arranged as a collection of individual cells arranged in rows and columns.When the user edits the data there's a button that he clicks and calls a function that saves the data to a database, and in this function i have to validate the data before sending it.I want to use simple validators (Number Validator, String Validator, etc) but i don't know how to set the source of this validators to the specified rows in the second column.All you need to do is set the list control's item Editors differ from item Renderers in that only one instance of the item Editor is seen, just on the cell being edited.The item Editor is not seen until the cell to be edited receives input focus.
