                                        </div>

                                    </ContentTemplate>
                                </ajaxToolkit:TabPanel>
                                <ajaxToolkit:TabPanel ID="TabPanel2" runat="server" HeaderText="services">

                                        <div style="height: 100px; width: 200px; overflow: Auto">
                                            <asp:DataList ID="DataList2" runat="server" CellPadding="2" CellSpacing="2">
                                                <ItemTemplate>
                                                    <asp:CheckBox ID="checkbox" runat="server" />
                                                    <asp:LinkButton Text='<%#Eval("SNA")%>' ID="lnkpro1" runat="server" CssClass="linkbutton"
                                                        OnClick="btn_Click1" CommandArgument='<%# Eval("Code") %>'></asp:LinkButton>
                                                </ItemTemplate>
                                            </asp:DataList>
                                        </div>
                                    </ContentTemplate>
                                </ajaxToolkit:TabPanel>
                            </ajaxToolkit:TabContainer>

Now my question :
This code block results in a list of link buttons in front of them all checkboxes. So what i want is to get the respective linkbutton value on checkbox checkchanged. Is it possible? for example
[] linkbtn1
[] linkbtn2
when i check on first checkbox the id not text of linkbutton1 should be fetched.([] is checkbox )

You can use JQuery for this purpose

JavaScript

$(document).ready(function () {
           $('#<%=checkbox.ClientID %>').change(function () {
               var optId = $(this).siblings("a").attr('id');
               alert(optId);
           });
       });

OR

JavaScript

  $(document).ready(function(){
    $("input[type=checkbox]").change(function(){
        if($(this).is(":checked")){
           var id = $(this).siblings("a").attr('id');
            alert(id);
           }else{
            alert("Unchecked")  
           }
        });

});
});

Hi. Try like this in the server event.

C#

protected void checkLike_CheckedChanged(object sender, EventArgs e)
        {

            DataListItem datalistitem = (DataListItem)(sender as CheckBox).Parent;
            LinkButton lnkpro = datalistitem.FindControl("lnkpro") as LinkButton;
            string linktext = lnkpro.Text;
            string clientID = lnkpro.ClientID;


        }
