Hi If you have adjusted your CustomDataGrid class, the question is how to intergrate it. The easiest way is to use the VS designer and add a normal Datagrid. After that you replace the line: this.dataGrid1 = new System.Windows.Forms.DataGrid(); with: this.dataGrid1 = new CustomDataGrid(); This works, because CustomDataGrid is derived from DataGrid. Anotherway would be to create the CustomDataGrid (the same way), but compile it to its own assembly, then add it to components in the designer. Simon

Override methods: ProcessKeyPreview() or, maybe ProcessDialogKey() Not tested. I override another keys.
