Glad it helped.

This really helped. Thanks a lot :)

you can do the post back for example on the SelectionChanged Event of a WebDropdown.

      function cboAAA_SelectionChanged(sender, eventArgs) {

            document.getElementById("<%= cmdDoRefresh.ClientID %>").click();

        }

------------

update panel and trigger

------------------------

 <asp:UpdatePanel ID="UpdatePanel1" runat="server">

                    <ContentTemplate>

                        <asp:Button ID="cmdDoRefresh" runat="server" Text="Refresh" />

                        <ig:WebDataGrid ID="WebDataGrid1" runat="server" Height="350px" Width="977px"                                    AutoGenerateColumns="False"

                            DataSourceID="SqlDataSource1" DataKeyFields="MainKey">

                            ******here the bound columns ******

                        </ig:WebDataGrid>

                    </ContentTemplate>

                    <Triggers>

                        <asp:AsyncPostBackTrigger ControlID="cmdDoRefresh" EventName="click" />

                    </Triggers>

                </asp:UpdatePanel>

What is firing the RunThisAfterAsyncPostback() call?  I've tried to run the example code but javascript is not firing.
