Others May benefit from this WPF "Dynamic Data Triggers" in code behind method

This code allows users to highlight data rows with the specified text they want.

    var st = new Style();
    st.TargetType = typeof(DataGridRow);
    var RedSetter = new Setter( DataGridRow.BackgroundProperty, Brushes.Red);
    var dt = new DataTrigger(){
        Value = CurrentTextToFilter,
        Binding = new Binding("Value")               
    };
    dt.Setters.Add(RedSetter);
    st.Triggers.Add(dt);
    XDG.RowStyle = st;
    PropChanged("MainDataCollection");

• The parm CurrentTextToFilter the text the user entered into a XAML Textbox.Text property that was bound to the code behind.

• The variable XDG is the datagrid XAML name and the RowStyle is set to the new style.

• Make sure to add the setter to the DataTrigger as shown. If you add it directly to the Rowstyle, all the rows will turn red.
