Why is the dataGridView1_SortCompare function not working ?

Dong Lam Trien

I have followed the https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.datagridviewsortcompareeventhandler?view=netframework-4.8 document but the dataGridView1_SortCompare column header sort doesn't work ? Although I have declared

this.dataGridView1.SortCompare += new System.Windows.Forms.DataGridViewSortCompareEventHandler(this.dataGridView1_SortCompare);

you see my attached file http://www.mediafire.com/file/pkkrtvd7mdhm94p/1.png

I learned the dataGridView1_SortCompare method does not allow assigning data from dataGridView1.DataSource if using the sort function

The SortCompare event does not occur when the DataSource property is set or when the VirtualMode property value is true.
