Because you are doing the search before checking the input. Try changing things around a bit

Private Sub BtnSearch_Click(sender As Object, e As EventArgs) Handles BtnSearch.Click

        If TxtId.Text = "" Then
            MsgBox("Please enter a ID to search")
            Exit Sub
        End If

        Try
            FillDataGridView1("select * from [Sheet1$] where ID='" & TxtId.Text & "'")
            TxtFamilyname.Text = dt.Rows(0).Item(1)
            TxtGivenname.Text = dt.Rows(0).Item(2)
            TxtGender.Text = dt.Rows(0).Item(3)
            TxtDob.Text = dt.Rows(0).Item(4)
            TxtStreet.Text = dt.Rows(0).Item(5)
            TxtHouse.Text = dt.Rows(0).Item(6)
            TxtPostcode.Text = dt.Rows(0).Item(7)
            TxtCity.Text = dt.Rows(0).Item(8)
        Catch ex As Exception
            MsgBox(ex.Message, MsgBoxStyle.Critical, Text)
        End Try
 

End Sub
