XAML继承（不是代码隐藏）

Question

How is inheritance accomplished in XAML ?

Is it true that only the code-behind can be inherited and not the .xaml ( related question )? Is including the parent in the child control's namespace the only way of doing it?

There seems to be no general "inheritance" per se in XAML . There are questions about inheriting UserControl , etc. but not general inheritance .

Problem:

I have 2 xaml files, File1.xaml and File2.xaml , which are very alike. Can I create a SuperFile.xaml and put the bulk of the following code in it?

<UserControl ... >
    <Grid>
        <Grid.RowDefinitions ... />

        <DockPanel ... >
            <ToolBar ... >
                <!-- Some Buttons here:
                     File1.xaml to contain the Buttons "View" and "Export"
                     File2.xaml to contain the Buttons "Edit" and "Delete"
                 -->
            </ToolBar>
        </DockPanel>

        <igDP:XamDataGrid MouseDoubleClick="xamDataGrid1_MouseDoubleClick" ... />
    </Grid>
</UserControl>

The only things that differ in File1.xaml and File2.xaml are:

1. Button s in the ToolBar (see comment in the code)
2. The properties of XamDataGrid , primarily the events (what they do in each case).

How can I achieve this? Would I have to write the code-behind files for both the children separately ?

You can use a ResourceDictionary

Put all your generic templates and styles in a ResourceDictionary , then have both your UserControls import that ResourceDictionary

<UserControl.Resources>
    <ResourceDictionary Source="BaseStylesAndTemplates.xaml" />
</UserControl.Resources>
