Has anyone done validation on a datagrid cell? What I am after this something like this:
A user enters the cell, and edits it's contents. They are able to enter waht they like. They leave the cell, and the validation fires. If the cell content is invalid, an Alert is displayed with a message telling the user what is wrong is displayed, and then the user is forced back in to that cell to correct their input. The problem I am having is when the "tab" key is used to move to the next cell. The original cell fires the "cellFocusOut", but the next cell gets focus. If the data is in-valid, the alert shows, but when you click on it, the validation is fired again on the second cell and if it's content is in-valid, the alert shows again. If a mouse click is used, it seems to work *better* ...AND I can't seem to change the focus in the "cellFocusOut", but only on the "cellFocusIn" event... Has any one else succeeded at this?
