WPF DataGrid Row height Row height automatic calculation makes each row of rows highly adaptive text

The row height of the DataGrid for WPF is either auto or fixed: But the trouble is that each row is the same height.

The Loadingrow event of the DataGrid is required when you need to dynamically adjust the height of the row by content (mostly wrap-wrapped textbox or TextBlock).

The code is as follows:

 private void Dglist_loadingrow (object sender, DataGridRowEventArgs e) {e.row.height = 30; Rough calculation of row height.            For better display effect ContentInfo info = (contentinfo) e.row.datacontext; if (info = null) {//calculates the maximum length of text string maxlengthstring = info.name1.Length > I Nfo.name2.Length?                info.name1:info.name2; Gets the width of the text box for the wrapping, which is the actual width of the textbox or TextBlock inside the template, double textboxwidth = (this.                                 ACTUALWIDTH-300)/2;     var formattedtext = new FormattedText (maxlengthstring, CultureInfo.CurrentUICulture, Flowdirection.lefttoright, New Typeface (New FontFamily ("Microsoft Jas"), Fontstyles.normal, Fontweights.normal, fontstretches.normal), brushes.b                lack);                Double calculateheight = formattedtext.height * (formattedtext.width/textboxwidth); E.row.height = > calculateheight?            30:calculateheight; }        }

Effects (each row is different in height, adaptive):
