Its now 5 months later and I'm using Silverlight Toolkit March 2009 and this problem seems to be there still. Was it fixed it the mean time and am I missing something ?

In order to receive notification that a validation error has occurred, you must tell the binding engine that you wish to receive notifications by setting both the ValidatesOnExceptions and NotifyOnValidationError properties to true on the binding object. Setting ValidatesOnExceptions to true tells the binding engine to create a validation error when an exception occurs. Setting NotifyOnValidationError to true tells the binding engine to raise the BindingValidationError event when a validation error occurs and resolves.

Create an event handler on the target object or <br>any of its parents</br> to handle the BindingValidationError event. The BindingValidationError event is a routed event, so if you do not handle it on the element that raised the event, it will continue to bubble up until it is handled. For more information on routed events, see Events and Delegates

I find this from Silverlight SDK.

It looks like a bug in datagrid.

I don't know if you solved the problem, but i found something reading some blogs and trying some examples:

<TextBox BindingValidationError="TestDataGrid_BindingValidationError"

Text="{Binding Id, Mode=TwoWay, NotifyOnValidationError=true,ValidatesOnExceptions=true}" />

</DataTemplate>

If we add the handler to the textbox like you can see above everything works perfect.

Hope this help.

I am also waiting for removed editing datagrid events, which where there in Beta2. Hopefully DataGrid will be shipped soon as a patch somehow ;)...

wackyphill- We've been seeing the same thing. There is a thread going in the forums, but so far no response at all from MS. Jesse if you could make sure the right people see this we would appreciate it. I'm supposed to ship in a little over a week and this bug is giving me ulcers. silverlight.net/.../36559.aspx

Jesse,

Thanks for writing about this. It has been driving me crazy!

The datagrid also seems to have some rendering problems where it does not redraw all of its rows correctly in certain situations.

Like when a button in your grid fires an event and then the user sorts by a column...very frustrating.

Please tell me the DataGrid people are busy working to improve this very valuable control.

BTW if/when an update tot he DataGrid happens how will we get it and start using it instead of the existing one?

Note: IE8.B2 will only show the code_block vertical scrollbars in compatibility mode.
