Telerik documentation for context menu is missing very important thing

[Mateusz]

Hi,

Teleriks outdated documenation caused me, again, to lose some time finding solution.

https://docs.telerik.com/devtools/wpf/controls/radcontextmenu/how-to/use-radcontextmenu-with-radgridview

Here is implementation of RadContextMenu for RadGridView, step-by-step guide is clear and explains everything. But menu implemented in this way to my app didn't work. There is important property, not present in documentation:

BasedOn="{StaticResource RadMenuItemStyle}"

wwich changes Example 4

<Style x:Key="MenuItemContainerStyle" TargetType="telerik:RadMenuItem">
    <Setter Property="Header" Value="{Binding Text}"/>
    <Setter Property="ItemsSource" Value="{Binding SubItems}"/>
    <Setter Property="IsEnabled" Value="{Binding IsEnabled}"/>
</Style>

to

 

<Style x:Key="MenuItemContainerStyle"
                   TargetType="telerik:RadMenuItem"
                   BasedOn="{StaticResource RadMenuItemStyle}">
                <Setter Property="Header"
                        Value="{Binding Text}" />
                <Setter Property="ItemsSource"
                        Value="{Binding SubItems}" />
                <Setter Property="IsEnabled"
                        Value="{Binding IsEnabled}" />
            </Style>

 

Please, update your documentation to save others time. 

 

Best Regards,

Mateusz

Hello Mateusz,

Thank you for your feedback. 

Let me explain the reason for the styles being defined without the BasedOn property. Setting that property is only required if you are using the NoXaml binaries with implicit styles. In that case you need to base your style on the theme's default one as described in the Styling the Controls article. If you are using the Xaml binaries, there is no need for setting the BasedOn property.
