Question

I have a WPF DataGrid with some styling, properties and events.
I want to override its OnMouseLeftButtonDown and OnMouseLeftButtonUp events to do something.
How do I do this?
Thanks!

Create your own class based on DataGrid and add the event handlers you need. Then in your XAML use your DataGrid rather than the “normal” one.

public class MyDataGrid : DataGrid
{
    // Your overrides here
}

And in XAML:

<Window x:Class="MyProject.MyNamespaceMyClass"
        ....
        xmlns:local="clr-namespace:MyProject.MyNamespace">

    ....
    <local:MyDataGrid ... />
    ....

</Window>
