How to Override Global Style and Apply Custom DataGrid Style in XAML

To use your specified DataGrid style instead of a global one, you can add the style to the DataGrid explicitly by setting the Style property to the name of the style in XAML. For example:

<DataGrid Style='{StaticResource YourDataGridStyle}' .../>

Make sure to replace 'YourDataGridStyle' with the actual name of your style resource. This will override any global style for the DataGrid and apply your custom style.
