Hi eveyone, i start using AJAX (with asp.net 2.0 and vb) and i have a problem  :
if i don't decleare my function GetDataPanel  as shared ajax don't find it (no error but simply don't reach the function in debug mode).

- Why does my GetDataPanel function need to be "shared" ?
- There's a way to don't have to declare my function as shared ? (or a way to have access to my control and function in my web form from a shared function ???)

Expected result : get the text from a textbox in my webform from my GetDataPanel function

Here is the code i use to call this function

'This button call the javascript
<input id="Button1" type="button" name="button1" value="OK" onClick="updateDateKey();" />

'My javascript
    function updateDateKey() {
        var behavior = $find('dpe');
        if (behavior) {
            behavior.populate();
        }
    }

'My AJAX control
            <cc1:DynamicPopulateExtender ID="dpe" ClearContentsDuringUpdate="true" ServiceMethod="GetDataPanel" runat="server" TargetControlID="Panel1">
            </cc1:DynamicPopulateExtender>

'VB Function called from the ajax control
        <System.Web.Services.WebMethod()> _
        Public Shared Function GetDataPanel() As String
            Return TextBox1.Text
        End Function

Thanks a lot

It does have to be "Shared", and no, you can't access the other controls on the page (because the page is not instantiated).

Why not use an UpdatePanel instead of the DynamicPopulateExtender?  That works like a regular postback (but doesn't reload the page), so you could use values from other controls.
