I’m trying to get selected cell value of multi DataGridView in TabControl to main datagridview in form1 with VB.NET

Please Guide me

for example when I selected row in the Criteria1 tabcontrol with enter 2 times then the value is in the selected row in the DatagridView column (Criteria1,DesCriteria1) in form1

Form1 datagridview with selected row

Form2 datagridview in tabcontrol Criteria1 with selected row
then press keypress in keyboard with enter 2 times

The cell value from Form2 datagridview in tabcontrol Criteria1 Appears in the DatagridView form1

and also the same way for other tabcontrol criteria or other fields

Thanks
