Asp.Net CheckBoxList Selected checkbox id's getting using Jquery

Asp.Net CheckBoxList Selected checkbox id's getting using Jquery

Hi,

I am using .Net Framework 4.0 with Asp.Net C# along with Jquery v1.4.4 My problem is that how can i get no. of selected checkbox id's using jquery in comma seperated values? Below code runs successfully but on alert window i got undefined,undefined

Here's my Asp.Net Code:

  2.  <div>
  3.         <fieldset>
  4.             <legend>Multiple selection from CheckBoxList and show the selected checkbox id's</legend>
  5.             <asp:CheckBoxList ID="CheckBoxList" runat="server" ClientIDMode="Static" DataSourceID="sdsCheckBoxList"
  6.                 DataTextField="QualificationName" DataValueField="QulificationId">
  7.             </asp:CheckBoxList>
  8.             <asp:SqlDataSource ID="sdsCheckBoxList" runat="server" ConnectionString="<%$ ConnectionStrings:DataConnectionString %>"
  9.                 SelectCommand="SELECT [QulificationId], [QualificationName] FROM [DoctorQulification] ORDER BY [QulificationId]">
  10.             </asp:SqlDataSource>
  11.             <br />
  12.             <input id="btnCheckboxClick" name="btnCheckboxClick" type="button" value="Checkbox Click"
  13.                 onclick="btnCheckboxClicked()" />
  14.         </fieldset>
  15.     </div>

Here's my page.aspx.cs Code:

  2.  protected void Page_Load(object sender, EventArgs e)
  3.         {
  4.             if (!Page.IsPostBack)
  5.             {
  6.                 foreach (ListItem item in CheckBoxList.Items)
  7.                 {
  8.                     item.Attributes.Add("hiddenValue", item.Value);
  9.                 }
  10.             }
  11.         }

Here's my Jquery Code:

  2. var glbCheckBoxList = "";

  4. function btnCheckboxClicked() {

  6.     $('#CheckBoxList input:checkbox:checked').each(function () {

  8.         var checkBoxValue = $(this).parent().attr('hiddenValue');
  9.         glbCheckBoxList += checkBoxValue + ', ';
  10.     });
  11.     alert(glbCheckBoxList);
  12. }
Any idea ?
