Selection of checkboxes lost during pagination of gridview

I have a problem in gridview, as per requirement i have set No of Records per page = 4 in gridview. I have to select Checkbox against every complaint but problem is then when i got to next pge in gridview and e.g fro 1 to 2 then when i come back to page 1 then it doesn't show TICK in check boxes . It doesn't remember my selection when i browse to and back to page.

<asp:GridView ID="GridViewSmsComplaints" AllowPaging="True" PageSize="4" runat="server" AutoGenerateColumns="False" CssClass="mGrid" BorderColor="#333333"  Width="550px" OnPageIndexChanging="GridViewSmsComplaints_PageIndexChanging" >
               <Columns>
                <asp:BoundField HeaderText="ID" DataField="ID" /> 
                <asp:BoundField HeaderText="Recieving Date" DataField="RecievingDate" />  
                <%--<asp:BoundField HeaderText="ToMobileNo" DataField="ToMobileNo" />  --%>
                <asp:BoundField HeaderText="FromMobileNo" DataField="FromMobileNo" /> 
                <asp:BoundField HeaderText="Message" DataField="Message" >   
                   <ItemStyle Wrap="True" />
                   </asp:BoundField>
                <asp:TemplateField HeaderText="IsComplaint">
                 <ItemTemplate>
                  <asp:CheckBox ID="ckboxIsComplaint"  runat="server" Checked='<%# Convert.ToBoolean(Eval("IsComplaint").ToString()) %>' />
                 </ItemTemplate>
                </asp:TemplateField>
               </Columns>
            </asp:GridView>

As per comments...

If you do not update the underlying database by processing the OnCheckChanged event of the check box, then it will simply be reading the same data all the time.

From How to add event for Checkbox click in Asp.net Gridview Column, I have extracted the required information and tried to modify to fit your initial question.

<asp:TemplateField HeaderText="IsComplaint">
   <ItemTemplate>
      <asp:CheckBox ID="ckboxIsComplaint"  runat="server" Checked='<%# Convert.ToBoolean(Eval("IsComplaint").ToString()) %>' OnCheckedChanged="chk_CheckedChanged" AutoPostBack="true/>
   </ItemTemplate>
</asp:TemplateField>

add checkbox change event in aspx.cs page

protected void chk_CheckedChanged(object sender, EventArgs e)
{
    GridViewRow row = ((GridViewRow)((CheckBox)sender).NamingContainer);
    <your data source>.Rows[row.DataItemIndex]["B"] = ((CheckBox)GridViewSmsComplaints.Rows[row.RowIndex].FindControl("ckboxIsComplaint")).Checked;

}
