Devexpress gridview rowupdating event
Essentially, I need to obtain a Key/Value list of row value and column names for both the old row, and new row. May i know what level of tracking you would like to track, since the grid controls are bound with data table objects , can the message dispatcher built to monitor the level of data table objects ?
Although this isn't as big of a problem when you're referencing the text from web controls, getting in the habit now will prevent you from serious headaches and inefficiently checking for null and empty later. NET 4.0, you should have access to event, you need to pull the new values out of the front-end controls, and then re-bind your data.This is so somebody can change the whole row before it sends a message.The current solution I am using does not work, and is not even worth explaining.Once focus has moved to another row, the newly added row is added to the datasource and a blank new item row is displayed.The Validate Row event is raised when a modified row is about to lose focus.
To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.
