[Solved] Grid Named Brushes no longer working in latest version

[Simon]

After installing the latest version (Telerik UI for Windows 8.1 XAML, version=2014.1.221) I have noticed that the Grid Named Brushes no longer work.  The grid styling has gone back to the default (black/grey).  I have the named brushes below in a global style xaml, but they are no longer taking affect after the upgrade.  Other controls like the NumericBox and DatePikcer seem to be fine and their named brushes are working.  I tried reverting back to an older version and the styling starts to work again. Is this a new bug or has something changed?  Note I upgraded from 2 versions prior, so not sure when this behavior started appearing.

    <SolidColorBrush x:Key="TelerikGridBackgroundBrush" Color="White" />
    <SolidColorBrush x:Key="TelerikGridForegroundBrush" Color="Black" />
    <SolidColorBrush x:Key="TelerikGridBorderBrush" Color="LightGray" />
    <SolidColorBrush x:Key="TelerikGridHeaderBackgroundBrush" Color="LightGray" />
    <SolidColorBrush x:Key="TelerikGridHeaderForegroundBrush" Color="Black" />
    <SolidColorBrush x:Key="TelerikGridAlternateRowBackgroundBrush" Color="#E6E6E6" />

    <SolidColorBrush x:Key="TelerikGridShadowBrush" Color="LightGray" />
    <SolidColorBrush x:Key="TelerikGridInnerShadowBrush" Color="LightGray" />

    <SolidColorBrush x:Key="TelerikGridCurrentCellBackgroundBrush" Color="LightGray" />

    <SolidColorBrush x:Key="TelerikGridSelectedBackgroundBrush" Color="LightGray" />
    <SolidColorBrush x:Key="TelerikGridSelectedBorderBrush" Color="#00366B" />
    <SolidColorBrush x:Key="TelerikGridPointerOverBackgroundBrush" Color="LightGray" />

Hello Simon,

Thank you for contacting us.

We have tested the grid brushes and they are applied properly on our side. I have attached a sample project for demonstration. Could you please take a look and see if this works fine on your side. Since you say that the other brushes work well, I think it is possible that you have missed something in your code. Also, here are two articles from our online documentation with information how to use and override the Telerik brushes:

• Resolving Telerik named resources
• Telerik Named Brushes

If you cannot make the brushes work, could you please send us a project that reproduces the problem and we will investigate it.

I hope this helps. Let us know if you have further questions.

Regards,
Rositsa Topchiyska

I think I may have figured out the issue, but something must have changed between telerik versions causing it to break for us, as it was definitely working prior. It seems to be the difference in the way we are setting up the dictionaries in the app.xaml.  We have been using merged dictionaries and separate xaml files for styles, like this;
​ <Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Common/StandardStyles.xaml" />
<ResourceDictionary Source="Common/FieldMobileStyles.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>

This has always worked fine for us in previous versions.  (again note, we were on RadControls for Windows 8, Version=2013.3.1105).  But has broken in our upgrade to Telerik UI for Windows 8.1 XAML, Version=2014.1.221.

Your sample project has the styles setup like this;
​ <Application.Resources>
<ResourceDictionary>
<telerik:UserThemeResources x:Key="ThemeResource" DarkResourcesPath="ms-appx:///Dark.xaml"/>
<ResourceDictionary.ThemeDictionaries>
<ResourceDictionary x:Key="Default">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="{CustomResource DarkResourcesPath}"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</ResourceDictionary.ThemeDictionaries>
</ResourceDictionary>
</Application.Resources>

Is it something to do with this?  <telerik:UserThemeResources

I have reattached your sample solution with the files and changes on how we have been doing this, so you can see it does not work.

The other thing I noticed is that you can not override named brushes right on the page, I believe this previously worked as well, but don't remember for sure.

Let me know if you have any ideas on how I might be able to fix this given our current structure. Otherwise I can alter our code to load the dictionary similar to how you are doing it in your sample.  It also seems strange that this issue applies only to the Grid, all other telerik controls where we override named brushes still work the same as always with the same code structure.  There was likely some small change done to the grid which altered the way the named brushes are loaded/used.

Thanks again for your help on this.

Actually it will not let me attach the zipped solution, so I will try and email it to you.

How can I email you the changed sample solution files?

Thanks

Hello Simon,

Yes, the Telerik named brushes are resolved differently in Windows 8 and 8.1 version of the controls. Please, could you take a look at these articles from our online documentation where it is explained how to use the brushes in Windows 8.1:

• Resolving Telerik named resources
• Telerik Named Brushes

I hope this helps. Please, let us know if you still have any problems.
