title: How to avoid post-back of Check Box inside repeater
body: <p>I am newbie for asp.net,
  I have a repeater which contains check box,whenever I check the check box I am firing an event on checkchanged,but the page postbacks.
  I have an update panel for the entire content in my page,but still postback occurs.Is there anyway to avoid postback.
  (Ps:To avoid Postback,I am meaning to avoid the flicker that occurs)</p>
  
  <p>Thanks </p>
  
  <pre><code>   &lt;asp:Repeater ID="rptrDepartment" runat="server" OnItemCommand="rptrDepartment_ItemCommand"
                              OnItemDataBound="rptrdepartment_databound"&gt;
                              &lt;ItemTemplate&gt;
                                  &lt;tr&gt;
                                     &lt;td&gt;
                                        &lt;asp:CheckBox ID ="chkRow" runat="server" OnCheckedChanged="ChkRow_ChkChanged" AutoPostback="true" /&gt;
                                    &lt;/td&gt;
                                  &lt;/tr&gt;
                               &lt;/ItemTemplate&gt;
                   &lt;/asp:Repeater&gt;
  </code></pre>
  
  <p>And in my .cs page,</p>
  
  <pre><code>   protected void ChkRow_ChkChanged(object sender, EventArgs e)
  {
     //some method
  }
  </code></pre>
