SelectionChanged and datagrids
Not complaining just a curiosity. I have a selectionChanged handler in my data grid because I want to trap for it and act based one what the user selected. I discovered though, that if I have something selected, and then programmatically set the dgText of the datagrid, effectively deselecting anything, the datagrid does NOT get the selectionChanged message, even though the selection DID change. I suppose I could go into the behavior and modify it to suit my needs but it's no big deal.

Re: SelectionChanged and datagrids
Yes, that's what you need to do. I set the dghilitedline of datagrids by script frequently and that doesn't trigger a selectionChanged event so I have to send one in the script.

Re: SelectionChanged and datagrids
Ya I can easily do that, but I was commenting on the way it worked. I set the dgText of a datagrid a lot, so I would have to remember to do so each time. I was thinking it ought to be automatic.
