Listbox javascript selectindex

hi every one,

Can someone help me with Javascript codes? I have a databound listbox. I would like to do a javascript so that when user click on an item, it will pass that item value to a gridview. I don't want to do Autopostback with my listbox because it create problem with my Listsearch_Extender

Thank you so much

Do you mean something like this:

<asp:ListBox ID="ListBox1" runat="server" >
  <asp:ListItem>a</asp:ListItem>
  <asp:ListItem>b</asp:ListItem>
  <asp:ListItem>c</asp:ListItem>
</asp:ListBox>
Add a javascript function
 function Selection()
{
  alert(List.options[List.selectedIndex].value);
}
Then in code behind ,  
 
ListBox1.Attributes.Add("onchange", "Selection(this);");

Open in new window

I have a listbox databound listing of all the Project #. Then, when a user click on the Project #, it will pass the value to a gridview to view all the tasks available for that Project.

I would like to do this with JS script instead of Auto Postback because when I turn on AutoPostback for listbox, my listsearch_extender does not work

Thanks
