Cell and row error glyphs are displayed when the Show Cell Errors and Show Row Errors property values are Used by the control to retrieve or store row height information in the data cache.
Call the Update Row Height Info method when changing the cached row height information outside of a Row Height Info Pushed event handler to ensure that the current value is used in the display of the control.
If the key pressed is Enter, I call End Edit(), otherwise I call base. It works great, except the Cell Validating event isn't fired. Column Index = 1 Then Dim i Row As Integer = My Base.
Currently, I'm just manually calling my validation logic before I call End Edit, but it seems like I'm missing something.
When a cell is modified in any way it is automatically marked as "dirty", when you call data Grid. Validate() you are telling to to check all of the cells which have been modified!

If your data is read-only, the event may be the only event you will need to handle.
