Hi Peter,
Sorry it's my fault. I incorrectly used the "AutoCompleteExtender1" as the
__EVENTTARGET. It should be "UpdatePanel1". Here's the updated version:
Aspx.cs:
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
if (Request.Form["__EVENTTARGET"] != null &&
Request.Form["__EVENTTARGET"] == "UpdatePanel1" &&
Request.Form["__EVENTARGUMENT"] != null)
{
this.Label1.Text = "Posted at: " +
DateTime.Now.ToString() + ", Posted Data:" +
Request.Form["__EVENTARGUMENT"];
}
}
}
Aspx:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript">
function Test(sender,e)
{
__doPostBack("UpdatePanel1",sender._element.value) ;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
<Services>
<asp:ServiceReference Path="WebService1.asmx" />
</Services>
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<cc1:AutoCompleteExtender OnClientItemSelected="Test"
ID="AutoCompleteExtender1" runat="server"
TargetControlID="TextBox1" ServicePath="WebService1.asmx"
ServiceMethod="GetCompletionList" MinimumPrefixLength="1">
</cc1:AutoCompleteExtender>
<asp:Label ID="Label1" runat="server" ></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
Sorry again for my mistake.
If you have further questions please feel free to ask.

| Hello Peter,
| >
| From your description you are using AutoCompleteExtender and want to
| trigger a client or server side (prefered) function when the selected
item
| is changed, right? If so you can try to set OnClientItemSelected to
| trigger
| a client side function, like below:
| >
| <asp:ScriptManager ID="ScriptManager1" runat="server">
| <Services>
| >
| <asp:ServiceReference Path="WebService1.asmx" />
| >
| </Services>
| >
| >
| </asp:ScriptManager>
| >
| <asp:UpdatePanel ID="UpdatePanel1" runat="server">
| <ContentTemplate>
| <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
| <cc1:AutoCompleteExtender OnClientItemSelected="Test"
| ID="AutoCompleteExtender1" runat="server"
| TargetControlID="TextBox1" ServicePath="WebService1.asmx"
| ServiceMethod="GetCompletionList" MinimumPrefixLength="1">
| </cc1:AutoCompleteExtender>
| >
| <%-- Other UI, such as GridView--%>
| >
| </ContentTemplate>
| </asp:UpdatePanel>
| >
| Then in the JavaScript function you can inform the server.
| >
| <script type="text/javascript">
| function Test(sender,e)
| {
| >
| __doPostBack("AutoCompleteExtender1",sender._eleme nt.value);
| >
| }
| </script>
| >
| aspx.cs:
| >
| protected void Page_Load(object sender, EventArgs e)
| {
| if (IsPostBack)
| {
| //Check Request.Form["__EVENTTARGET"] and
| Request.Form["__EVENTARGUMENT"]
| //Update UI
| }
| }
| >
| Please have a try and let me know if it works.

| | I have an AutoCompleteExtender which works fine- I am using name, id
| pair
| in
| | the WebService , but what I am trying to do is: once the user selects
an
| | item from the AutoCompleteExtender I want to automatically retreive
data
| | from the database and populate the fields on the screen.
| |
| | How do I trigger a server side event after the user selects an item
from
| the
| | AutoCompleteExtender or retrieve data from database on client side
| event?
| |
| |
| |
| | Thank You
| |

| The suggested solution works, thank you very much!
|
| Is there a way to do the same thing but using Ajax so the user does not
see
| the page refresh? The solution works fine, but you can see the page
refresh
| after the user selects the Item from the AutoCompleteExtender, which kind
of
| defeats using Ajax in the first place.
