questo il mio codice-- Using o Conn As New Sql Connection(Configuration Manager.

I have a radgrid using a form template to do my inserts and updates.
I was wondering how you would keep the grid in edit or update mode from the on Insert Command/on Update Comman event handlers?For example lets say when i jut clicked on edit button the textbox's value was "test1", i changed it to "test2" and pressed update button, after the code: protected void Update Command(object source, Grid Command Event Args e) is executed the textbox is again have value "test1", but I want it to be "test2" (the value it has just before i pressed update button). Is it possible to do the same in rad Grid_Batch Edit Command(object sender, Grid Batch Editing Event Args e) event ?I have a grid which has the Add/Save/Cancel command as Command Items. During insert/update, I want to validate the values after the user enters values and throw an error message on clicking Save.To complete the lessons in this chapter, you should be familiar with developing applications with Microsoft Visual Studio 2010 by using Microsoft Visual Basic or Microsoft Visual C#.In addition, you should be comfortable with all of the following: REAL WORLD: Mike Snell Not all applications require developers to write custom, abstracted data layers and reusable frameworks.
