Hi,
I need to make an editable Telerik RadComboBox show a customized tooltip when the data entered is invalid (in Silverlight). More specifically, instead of the error message I want to display an "X" in a red circle, and I want it to happen automatically (i.e., the user shouldn't have to mouse over the upper-right corner).
I've done the customizations. My problem is that the tooltip won't display the first time there is a validation error, but it will display for all subsequent errors. I need it to happen the first time too.
Here is the project containing the customizations I've done using Expression Blend. Just enter a non-numeric string in the radcombobox to make it invalid. Then make it valid and invalid once more, and you'll see the tooltip. The style I created is in App.xaml.

Thanks in advance.
EDIT: for quicker reference, here is the code for App.xaml:

Also, it would be great if it were possible to keep the tooltip visible for as long as the data is invalid (in other words, once the user moves the mouse pointer away from the upper-right corner, the tooltip should not vanish).
