Hi,

after updating, I'm getting error when I try to change  AccentColor of metro theme. This is the error:

"Cannot set a property on object 'Telerik.Windows.Controls.MetroColorPalette' because it is in a read-only state."

Stack trace:

My code:

var findResource = FindResource("BaseColor");
if (findResource != null)
    MetroColors.PaletteInstance.AccentColor = (Color)findResource;

Hello,

 Currently you could set the colors of the MetroTheme only before the theme is actually created. For example before InitializeComponent() you could first set the MetroColors.... and then ApplicationTheme = new MetroTheme().

Hello,

My application allows you to modify template Metro AccentColor per user. It means that now I can not do this work because you can only assign the color at the beginning of the program??
If that is true, do not understand why the updates, you change things that were very good ....

Thanks and sorry for my English

Hello,

 Indeed, you may not change it runtime any more. This is due to the fact that we will use VisualStateManager everywhere.
