Hi Team,

We faced the issue "Context menu item style did not apply when manually opening the context menu." In the Dictionary1.xaml and Dictionary2.xaml files, we defined two distinct menu item styles. Initially, we merged the Dicitonary1.xaml style in the main window and we set the IsOpen property value to true. Now if we try to open the context menu by clicking the Left Button, the context menu was displayed but the style was not properly applied.

Please refer to the following screenshot. Here, the applied style didn’t display when left-clicking the button.

When you right-click the button, the menu item style is applied as expected; it takes the style from the Dictionary1.xaml file.
So when opening the context menu with the left click, the context menu style is not properly applied but it works fine in the right button click. So can you please check this issue on your end and provide a solution?

Please refer to the following screenshot. Here, the applied style properly when right-clicking the button.

Replication steps:

1. Run the attached demo

2. Click the ‘Open context menu’ button.

3. Context menu shown but the style didn’t apply.

4. Right-click the ‘Open context menu’ button

5. Now the menu item styles are applied properly(style from Dictionary1.xaml)

Please find the sample below,
