http://stackoverflow.com/questions/3113851/selecting-item-from-asp-net-listbox-using-jquery[^]

Here is the code

XML

<div>
      <asp:ListBox ID="ListBox1" runat="server" Width="50px" Height="100px"
          SelectionMode="Multiple">
          <asp:ListItem Value="One">1</asp:ListItem>
          <asp:ListItem Value="Two">2</asp:ListItem>
          <asp:ListItem Value="Third">3</asp:ListItem>
          <asp:ListItem Value="Four">4</asp:ListItem>
          <asp:ListItem Value="Five">5</asp:ListItem>
      </asp:ListBox>
      <br />
      <asp:TextBox ID="text1" runat="server"></asp:TextBox>
  </div>

XML

<script type="text/javascript">

    $("#<%=ListBox1.ClientID %>").change(function () {
        $("#<%=text1.ClientID %>").val($(this).val());
    });


</script>

Hope it helps...

Edited

Jquery code

C#

$("#<%=ListBox1.ClientID %>").change(function () {
      var selectedItems = $(this).val();
      var value = 0;
      for (var i = 0; i < selectedItems.length; i++) {
          value = parseInt(value)+ parseInt(selectedItems[i]);
      }
      $("#<%=text1.ClientID %>").val(value);
  });

Assuming the listbox is like this

XML

<asp:ListBox ID="ListBox1" runat="server" Width="50px" Height="100px"
         SelectionMode="Multiple">
         <asp:ListItem Value="1">1</asp:ListItem>
         <asp:ListItem Value="2">2</asp:ListItem>
         <asp:ListItem Value="3">3</asp:ListItem>
         <asp:ListItem Value="4">4</asp:ListItem>
         <asp:ListItem Value="5">5</asp:ListItem>
     </asp:ListBox>

Solution 1

Hello
Check out this sample
http://jsfiddle.net/JthcU/[^]

You will get comma separated string of selected items.
If nothing is selected then it will return null.

Solution 3

Try this:

JavaScript

var sum = 0;
$('.ListBox1 option').each(function(index) {
  if ( ($(this).is(':selected')) {
    // do stuff if selected
    sum += this.value;
  }
  else {
   // this one isn't selected, do other stuff
  }
});
