Display selected row from datagridview to checkbox vb

I have a form that adds information from the textbox and checkbox to the datagridview. The datagridview has 2 columns First Name and Membership status.

I want the application to checkmark the membership checkbox if the selected row has the name member in that particular row.

So far I got this which displays the first name in the text box, but does not check mark the checkbox if the row contains a member.

If e.RowIndex >= 0 Then

  Dim row As DataGridViewRow
   row = Me.DataGridView1.Rows(e.RowIndex)

    FirstNametxt.Text = row.Cells("Column1").Value.ToString
 End If
