We are very happy to get out a bug-fix release of the Silverlight 2 DataGrid.  It should be very easy to simply drop this into your project and the get the benefits of a bunch of bug fixes..

This updated DataGrid contains almost 30 fixes to the top issues that we heard, including:

• Rows containing focus no longer disappear when the ItemsSource changes
• ComboBox and other controls opening a popup now work as expected
• DataGrid Selection is preserved when sorting
• Buttons outside the DataGrid work as expected when they are clicked while the DataGrid is in editing mode
• Improved FrozenColumn behavior
• Improved cell currency
• SelectedItem is updated before the CurrentCellChanged event is raised
• Many more...

For the full list of fixes check out this post by Brian Braeckel one of our DataGrid developers.
