Docking manager custom menu items not maintaining checked status

[Josepth Badrouk]

I have a docking manager with the following custom menu:

<syncfusion:CustomMenuItemCollection>
    <syncfusion:CustomMenuItem x:Name="Menu1" Click="MenuItem_Clicked" IsChecked="True" />
    <syncfusion:CustomMenuItem x:Name="Menu2" Click="MenuItem_Clicked" IsChecked="True" />
    <syncfusion:CustomMenuItem x:Name="Menu3" Click="MenuItem_Clicked" IsChecked="True" />
    <syncfusion:CustomMenuItem x:Name="Menu4" Click="MenuItem_Clicked" IsChecked="True" />
    <syncfusion:CustomMenuItem x:Name="Menu5" Click="MenuItem_Clicked" IsChecked="True" />
    <syncfusion:CustomMenuItem x:Name="Menu6" Click="MenuItem_Clicked" IsChecked="True" />
    <syncfusion:CustomMenuItem x:Name="Menu7" Click="MenuItem_Clicked" IsChecked="True" />
</syncfusion:CustomMenuItemCollection>

When opening the context menu, I have an event set to check/uncheck some of the menu items based on their visibility in the docking manager. However, this is not working at all and constantly shows the menu items as unchecked. Example, menu 1 and 2 should be checked:

However, if I wrap all the menu items in a parent menu item, the code works properly and displays the menu items with the correct checked/unchecked state:

<syncfusion:CustomMenuItemCollection>
<syncfusion:CustomMenuItem x:Name="ParentMenu" SubmenuOpened="CustomMenuItem_OnSubmenuOpened">
​    <syncfusion:CustomMenuItem x:Name="Menu1" Click="MenuItem_Clicked" IsChecked="True" />
    <syncfusion:CustomMenuItem x:Name="Menu2" Click="MenuItem_Clicked" IsChecked="True" />

    <syncfusion:CustomMenuItem x:Name="Menu3" Click="MenuItem_Clicked" IsChecked="True" />
    <syncfusion:CustomMenuItem x:Name="Menu4" Click="MenuItem_Clicked" IsChecked="True" />
    <syncfusion:CustomMenuItem x:Name="Menu5" Click="MenuItem_Clicked" IsChecked="True" />
    <syncfusion:CustomMenuItem x:Name="Menu6" Click="MenuItem_Clicked" IsChecked="True" />
    <syncfusion:CustomMenuItem x:Name="Menu7" Click="MenuItem_Clicked" IsChecked="True" /></syncfusion:CustomMenuItem>
</syncfusion:CustomMenuItemCollection>

 I want to get away from needing a parent menu item. How can I achieve this to keep track of the checked/unchecked state without a parent menu item, or is this a bug?

Hi Joseph Badrouk,

We have included the fix for the reported issue “Checked status is not update properly in CustomMenuItems of DockingManager” in our latest release version 31.2.12 which is available for download ( https://www.nuget.org/).

 

Root Cause: The issue occurs because the update logic only resets the parent menu item's checked state without cascading or synchronizing the state to the custom items.

 

We thank you for your support and appreciate your patience in waiting for this update. Please get in touch with us if you require any further assistance
