How to call same event of user control on multiple aspx.cs pages

Question

Hi All,

I have one user control which has 2 gridview first grid has columns (GroupName, Description, chkRemove checkbox) another gridview has columns (GroupName, Description, chkAdd), apart from that i dont have any code on .cs file of usercontrol.

I want to call same user control on 4 aspx pages and datagrid binding, sorting, paging and search functionality i want to do on respective aspx.cs pages not on user control where i am calling this uercontrol because for every aspx page field name is same but when i am binding the data to the grid that logic is different.

For first aspx page i called my usercontrol like this and everything is working fine: -

 <asp:View ID="vManageGroups" EnableTheming="true" EnableViewState="true" runat="server">
             <ajax:TabContainer runat = "server">
                <ajax:TabPanel HeaderText="Default Role Groups" ID="tpRoleGroups" runat="server">
                    <HeaderTemplate>
                        Default Role Groups
                    </HeaderTemplate>
                    <ContentTemplate>
                      <Level3Groups:GroupSelector ID="gsAU3Groups" runat="server"  OnGroupRebind="gsAU3GroupRebind"
                      OnGroupAdded="gsAU3GroupAdded" OnGroupRemoved="gsAU3GroupRemoved"  OnGroupSort="gsAU3GroupSort" />
                    </ContentTemplate>    
                </ajax:TabPanel>
            </ajax:TabContainer>

and on user control i have created delegate and event.

public delegate void GroupAction(object sender, EventArgs e, string groupName);
    public event GroupAction GroupAdded;
    public event GroupAction GroupRemoved;

    public delegate void GridViewPaging(object sender, GridViewPageEventArgs e, string groupName);
    public event GridViewPaging GroupRebind;

    public delegate void GridViewSort(object sender, GridViewSortEventArgs e);
    public event GridViewSort GroupSort;

then in user control for chkAdd checkbox i have added this code and after that i did all my
coding on aspx.cs page and it is working fine.
usercontrol.ascs.cs
protected void chkAdd_Click(object sender, EventArgs e)
    {
        CheckBox chkAdd = (CheckBox)sender;
        GridViewRow viewRow = (GridViewRow)chkAdd.Parent.Parent;
        HiddenField hfAddName = (HiddenField)viewRow.FindControl("hfaddName");
        string groupAddName = hfAddName.Value;
        GroupAdded(sender, e, groupAddName);
    }
and Aspx.cs
protected void gsAU3GroupAdded(object sender, EventArgs e, string groupName)
{
        // My code here
}
Same type of thing i did for ChkRemove_Click and paging and sorting.

Now problem is i want to call this usercontrol on second aspx page then how to handle 
that page's logic inside the chkadd_click event on usercontrol.ascx.cs. 
I want any if like condition, if this page is clicked then go on this event like this

let me know if you need any other information. Any help is appreciated.
