A linkButton onClientClick starts a new page and loads user control. In the user control I have radgrid and button those I have placed in ajaxpanel.

<asp:UpdatePanel runat="server" ID="ajaxPanel">
    <ContentTemplate>
 
     
 
 
        <telerik:RadGrid ID="RadGrid1" Width="97%"            PageSize="15" runat="server" AllowSorting="True" AllowFilteringByColumn="True"
             GridLines="None" CellSpacing="0"
              >
 
             <MasterTableView Width="100%" AutoGenerateColumns="False" DataKeyNames="GrowerId">
 
                  <Columns>
                      <telerik:GridTemplateColumn UniqueName="TemplateColumn" SortExpression="CompanyName">
                      <HeaderTemplate>
 
                                         <asp:CheckBox id="headerChkbox"  OnCheckedChanged="chkHeader_CheckedChanged"  AutoPostBack="true" runat="server" Text="Select All" ></asp:CheckBox>
 
                                        </HeaderTemplate>
                        <ItemTemplate>
                             
                                <asp:checkbox ID="chkGrowerId" runat="server" />
                             
                        </ItemTemplate>
                        </telerik:GridTemplateColumn>
                      
                      <telerik:GridBoundColumn DataField="FirstName" HeaderText="FirstName"
                          SortExpression="FirstName" UniqueName="FirstName">
                      </telerik:GridBoundColumn>
                      <telerik:GridBoundColumn DataField="LastName" HeaderText="LastName"
                          SortExpression="LastName" UniqueName="LastName">
                      </telerik:GridBoundColumn>
                      <telerik:GridBoundColumn DataField="AddressLine" HeaderText="AddressLine"
                          SortExpression="AddressLine" UniqueName="AddressLine">
                      </telerik:GridBoundColumn>
                      <telerik:GridBoundColumn DataField="City" HeaderText="City"
                          SortExpression="City" UniqueName="City">
                      </telerik:GridBoundColumn>
                      <telerik:GridBoundColumn DataField="StateCode" HeaderText="StateCode"
                          SortExpression="StateCode" UniqueName="StateCode">
                      </telerik:GridBoundColumn>
                      <telerik:GridBoundColumn DataField="ZipCode" HeaderText="ZipCode"
                          SortExpression="ZipCode" UniqueName="ZipCode">
                      </telerik:GridBoundColumn>
                       
                  </Columns>
                </MasterTableView>
              <PagerStyle Mode="NextPrevAndNumeric" />
                <FilterMenu EnableTheming="True">
                    <CollapseAnimation Duration="200" Type="OutQuint" />
                </FilterMenu>
            </telerik:RadGrid>
            <asp:Button ID="btnCreateCsv" runat="server" Text ="Create Mailing List" OnClick="btnCreate_Click" />
    </ContentTemplate>
      
    </asp:UpdatePanel>

Hello Madhan,

Could you please ensure that you are loading the UserControl correctly as shown in the online demo below:
http://demos.telerik.com/aspnet-ajax/ajax/examples/common/loadingusercontrols/defaultcs.aspx
Also please inspect the server request and verify if any js errors appear when trying to fire the check changed or button click events.
