获取商店数据的选中复选框和Ajax发布保存方法

Question

我面临着如何获取所选复选框（单个或多个）的问题，并回发到从模态保存数据的方法。

复选框javascript的功能正在运行，到目前为止还不知道如何将它们放入ajax并发布。

点击复选框时，Ajax仍然无法获取复选框的数据！

这是ASPX的模态gridview代码：

<div class="modal-dialog">
 <div class="modal-body">
        <asp:UpdatePanel ID="updateGV" runat="server">
               <ContentTemplate>
            	<asp:Label CssClass="bolder" runat="server" ></asp:Label>
            	<input type="text" name="AddGroup" class="form-control" id="CreateGroup" onblur="GroupCheck()" />
            	 <br /><br />
            	  <asp:GridView runat="server" ID="gvLIST"  CssClass="table table-bordered"  
            					AutoGenerateColumns="false" >
            		  <Columns>
            			  <asp:TemplateField>
            				  <HeaderTemplate>
            					  <asp:CheckBox ID="gvCHECKALL" runat="server" onclick="allCHKBOX(this);"  />
            				  </HeaderTemplate>
            				  <ItemTemplate>
            					  <asp:CheckBox ID="gvCHECK" runat="server"  onclick="singleCHKBOX(this)" />
            				  </ItemTemplate>
            			  </asp:TemplateField>
            			  <asp:TemplateField HeaderText="ID" Visible="false">
            					<ItemTemplate>
            						<asp:Label ID="ID" runat ="server" Text='<%#Eval("ID") %>'  style="display:none"/> 
            					</ItemTemplate>
            			 </asp:TemplateField>
            			 <asp:BoundField HeaderText="Name" DataField="NME"/>
            		  </Columns>
            	  </asp:GridView>
               </ContentTemplate>
            </asp:UpdatePanel>
<button id="btnROUPSAVE" runat="server" disabled="disabled" onclick="btnGroupSaveClick()"  >
