Question

My program works well.

  <Window.Resources>    

        <ResourceDictionary Source="GlassButton.xaml">
        </ResourceDictionary>
    </Window.Resources>    

But after adding DataGrid on the “MainWindow” shows error in string:

   <ResourceDictionary Source="GlassButton.xaml">

The part of Window.Resources has changed after adding DataGrid and it became like that:

<Window.Resources>            
        <ResourceDictionary Source="GlassButton.xaml">
            <my:DepartmentDataSet x:Key="DepartmentDataSet" />
            <CollectionViewSource x:Key="DepViewSource" Source="{Binding Path=DEP, Source={StaticResource DepartmentDataSet}}" />
        </ResourceDictionary>

The error message shows:
“Property “System.Windows.ResourceDictionary.DeferrableContent” is called exception.”: Number of row “10” and position in a row “29”.
With best regards

I’ve found the reason. I need to put code in “< ResourceDictionary.Merged >”. With this added code program works very well!

<ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
             <ResourceDictionary Source="GlassButton.xaml"/>
    </ResourceDictionary.MergedDictionaries>
            <my:DepartmentDataSet x:Key="DepartmentDataSet" />
            <CollectionViewSource x:Key="DepViewSource" Source="{Binding Path=DEP, Source={StaticResource DepartmentDataSet}}" />
        </ResourceDictionary>
