Maybe it's about " " ...

If cmbside.Text = "" And cmbDamage.Text = "" Then
    MsgBox("Please Select Both Item", MessageBoxIcon.Information)
End If

or

If cmbside.SelectedIndex = -1 And cmbDamage.SelectedIndex = -1 Then
    MsgBox("Please Select Both Item", MessageBoxIcon.Information)
End If

If you want to add both combobox value in gridview check the condition like this

 If ComboBox1.Text.Trim = String.Empty OrElse ComboBox2.Text.Trim = String.Empty Then
            MsgBox("Please Select Both Item", MessageBoxIcon.Information)
        End If

It doesn't really matter in this case, but you should really use OrElse instead of Or.
