I have done my invitee management project for about $80\%$ but stuck with the edit part. I want the program to do the following :

$-$ When we click view, only datagridview$1$ appears.

$-$ When we want to modify the data, go to datagridview$2,$ inside the datagridview$2$ can add, update or delete. After modification, click edit. The data will automatically refreshes in the datagridview$1.$

I will attach my coding here, please help me:

private void btn$\_$Edit$\_$Click$($object sender$,$ EventArgs e$)$

$\{$

$//$ Handle multiple delete in DataGridView$2$

$//$ Update the shared DataTable with changes from DataGridView$2$

dataGridView$2.$EndEdit$()$; $//$ Commit any pending edits

adapter.Update$($dataSet$.$Tables$["$Invitees$"])$; $//$ Update the database with changes

RefreshDataGridView$()$; $//$ Refresh DataGridView$1$ to reflect the changes

$\}$

$\}$

private void btn$\_$Clear$\_$Click$($object sender$,$ EventArgs e$)$

$\{$

$//$ Clear all textboxes and reset DataGridView visibility

textBox$\_$Name.Text $=""$;

textBox$\_$TableNo.Text $=""$;

textBox$\_$searchInv.Text $=""$;

textBox$\_$searchTableNo.Text $=""$;

dataGridView$2.$DataSource $=$ null;

dataGridView$1.$Visible $=$ true;

RefreshDataGridView$()$;

$\}$
