Set Tab Index on Gridviw Linkbutton Click

Hi

I have a gridview hyperlink field whci sets the ID in a quesrystring.

Rather than navigate to a new page I want it to stay on the same page but just display a different ajax tab.

TabContainer1.ActiveTab = TabContainer1.Tabs(5)

This code sets the querystring correctly.......

<asp:TemplateField>
                            <ItemTemplate>
                                <asp:HyperLink ID="HyperLink1" runat="server" 
                                    NavigateUrl='<%# Eval("UserID", "RegisteredUsers.aspx?id={0}") %>' 
                        Text="More Details"></asp:HyperLink>
                            </ItemTemplate>
                        </asp:TemplateField>

Select allOpen in new window

All I want to do is now display the different tab.

How can I access the Hyperlink1 click event programatically so I can set this everytime somone clicks on the hyperlink.

TabContainer1.ActiveTab = TabContainer1.Tabs(5)

Select allOpen in new window
