Separator in Header Context or Context Menu?

[Helmut Wahrmann]

Hi,

please look at your samples here: https://help.syncfusion.com/wpf/datagrid/context-menu

All the screenshots show a separator, while the code doesn't.

When adding a Headercontext menu or a SfDataGrid.ContextMenu with 18.3 i get on right-click:

System.InvalidOperationException: 'A style intended for type 'MenuItem' cannot be applied to type 'Separator'.'

Code Snippet:

     <syncfusion:SfDataGrid.ContextMenu>

        <ContextMenu>

          <MenuItem Header="Item1" >

          </MenuItem>

          <Separator/>

          <MenuItem Header="Item2" >

          </MenuItem>

        </ContextMenu>

      </syncfusion:SfDataGrid.ContextMenu>

Removing the Separator it works.

Hi Vijayarasan S,

sure. while trying to record this i noticed that in some starts it works and others it fails.

So out of 10 starts it fails 6 times and it works 4 times.

i removed the separator from the Header Context and left it in the context menu of the grid itself.

the attached video shows it failing, when i did a right click in the grid after startup.

then i started again and now it worked.

Also attached the xaml file with my definitions.

regards,

Helmut

Found a pattern.

It NEVER crashes if i open te Header Context Menu, without the separators, first.

it ALWAYS crashes, if i open the Grid Context Menu first, without opening the Header Context.

Nevermind: Fixed it by defining my own style for Menuitem and separator
