Increase the Height of Column Header in a Windows Forms DataGrid (Not DataGridView)

I am working on a Windows Forms application and I have a DataGrid for which I am trying to increase the height of the column headers.

I know how its done for a datagridview but I am unsure about the DataGrid.

I have a column named Actual \n Qty, and this is being displayed as below:

May I know a way we could increase column header height?

Height of the column header in DataGrid is calculated based on HeaderFont property and is stored in a private filed headerFontHeight. You can get the field using reflection and change its value this way:

var p = typeof(DataGrid).GetField("headerFontHeight",
    System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
p.SetValue(dataGrid1, dataGrid1.HeaderFont.Height * 2);

var m = typeof(DataGrid).GetMethod("OnLayout",
    System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
m.Invoke(dataGrid1, new object[] { null });
dataGrid1.Invalidate();

enter image description here

You can assign the height which you think is enough or you can calculate the height of text of all columns and set the field to the maximum value.
