Firing GridView SelectedIndexChanged from code behind

I have a gridview with the implementation of SelectedIndexChanged.

<asp:GridView ID="gvCalloutTeam" runat="server" OnRowDataBound="gvCalloutTeam_RowDataBound" OnSelectedIndexChanged="gvCalloutTeam_SelectedIndexChanged"
                            AutoGenerateColumns="False" EnableViewState="False" BackColor="White" BorderColor="#cccccc" BorderWidth="1px" CellPadding="2"
                            EmptyDataText="No person found" GridLines="None" Width="100%">
                            <AlternatingRowStyle BackColor="#ededed" />
                            <Columns>
                                .......... List of columns..............
                            </Columns>
                            <FooterStyle BackColor="#cccccc" ForeColor="Black" />
                            <HeaderStyle BackColor="#6699cc" Font-Bold="True" ForeColor="White" BorderColor="#cccccc" BorderWidth="1px" />
                            <PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
                            <RowStyle BackColor="#fefefe" ForeColor="Black" />
                            <SelectedRowStyle BackColor="#008A8C" Font-Bold="True" ForeColor="White" />
                            <SortedAscendingCellStyle BackColor="#F1F1F1" />
                            <SortedAscendingHeaderStyle BackColor="#0000A9" />
                            <SortedDescendingCellStyle BackColor="#CAC9C9" />
                            <SortedDescendingHeaderStyle BackColor="#000065" />
                        </asp:GridView>

I have a check box on the page and CheckedChanged Event implemented on that.

<asp:CheckBox ID="cbTakeOutOrder" runat="server" Text="Take out of order" OnCheckedChanged="cbTakeOutOrder_CheckedChanged" AutoPostBack="true" />

I'm trying to set SelectedIndex of GridView from this event.

protected void cbTakeOutOrder_CheckedChanged(object sender, EventArgs e)
    {
        if (!cbTakeOutOrder.Checked && gvCalloutTeam.Rows.Count > 0)
            gvCalloutTeam.SelectedIndex = 0;
    }

But it doesn't fire the SelectedIndexChanged event of GridView. If I select the row on UI, it fires but if I change Index in code, it doesn't fire the event. Is there a way to invoke the event, after changing SelectedIndex in code behind?

  protected void gvCalloutTeam_SelectedIndexChanged(object sender, EventArgs e)
        {
//////////////////my logic 
}

If you are on .net 4.5, you can call SelectRow method on the GridView:

protected void cbTakeOutOrder_CheckedChanged(object sender, EventArgs e)
{
    if (!cbTakeOutOrder.Checked && gvCalloutTeam.Rows.Count > 0)
        gvCalloutTeam.SelectRow(0);
}
