Grid differeneces between 3.6.1 and 4.0.1?

[Deasun]

After upgrading the grids tag = <GridToolBar> seems to have disappeared from the control.

Was it replaced by <GridToolBarTemplate>?

If so why doe I get a red error line under the tag when I rename the tag from the old to the new?

 

Tis at 4.0.1 now:

try to use the :  Icon="@FontIcon.FileExcel"

Hello Deasun,

Indeed, as Tobren said, the issue is with the Icon. You can see a list of all breaking changes from the 4.0 documentation article.
