mmDataGridView has these properties turned off:

// 
// mmDataGridView
// 
this.AllowUserToAddRows = false;
this.AllowUserToDeleteRows = false;

Any reason, side effects, not to use these behaviors?

InitializeComponent();

this.grdMyTable.AllowUserToAddRows = true;
this.grdMyTable.AllowUserToDeleteRows = true;

Thanks!
