I'm using PropertyGrid in C# too. The main problem with theValueChanged event, as currently implemented, is that it's not thateasy to find out what the value wasbefore it was edited, so that if the data entered is invalid, you canset it back. My hack around it is to store the current data valuein the Tag property, and upon validation, change the value of the Tagproperty, otherwise reset the value back to what's in the Tagproperty. Kinda hackish, but whatever works.

I finally got back in front of a PC with Codejock installed, so here's an update about detecting a value change in C#.

Indeed, the 'item' that was changed is exposed in the event args. An event handler might look like the following:

private void axPropertyGrid_ValueChanged(object sender, AxXtremePropertyGrid._DPropertyGridEvents_ValueChangedEvent e)
{
    Console.WriteLine("Value Changed for " + e.item.Caption);
}

The ValueChanged event in VB6 should be:

Private Sub PropertyGrid1_ValueChanged(ByVal Item As XtremePropertyGrid.IPropertyGridItem)

End Sub

I don't have the documents in front of me right now, but I believe the EventArgs for the 'ValueChanged' event will include a reference to the item that was modified.

I am using the property grid in a c#application. I need to be able to validate data that a user enters for a propertygrid item and then notify the user if its invalid data. I added the valuechanged event to my code, however there is no way to identify which item was the one modified. Is there a way to do this?

Thanks.
