How to change DataGrid style dictionary by Setter via C# in WinUI3?

Question

I have a DataGrid (CommunityToolkit.Controls), and I need to change some default style parameters. I can do it in XAML code via Setters. But I must do it programatically via C#. Can you give some C# examples how to make GridView style Setters to me? Thanks.

Let's say you have an DataGrid named DataGridControl. In code-behind you can set the Style programmatically like this:

var customStyle = new Style(typeof(DataGrid));

if (this.DataGridControl.Style is Style baseStyle)
{
    customStyle.BasedOn = baseStyle;
}

customStyle.Setters.Add(new Setter(DataGrid.RowHeightProperty, 50));

this.DataGridControl.Style = customStyle;
