Hi,

I'm using the CallbackPanel and trigger the callback with eo_Callback javascript function. The controls within the CallbackPanel are dynamically created.

The server-side code is executing well (suppose), but how can I initiate a response back to the client-side function (with specific parameters) in order to update the dynamically created control?
I appreciate if you could provide a short sample of the implementation of the server-side response initiation and the client-side after-execute function.

Thanks in advance!

Hi,

There are a number of ways to do this. One way is to simply render a chunk of JavaScript. For example:

Code: HTML/ASPX 
<eo:CallbackPanel runat="server" id="CallbackPanel1">
    ....other contents....
    <asp:Label runat="server" id="lblScript"></asp:Label>
</eo:CallbackPanel>


On the server side, you can do:

lblScript.Text = "<script type=\"text/javascript\">window.alert('hi!');</script>";

Once this code is executed, the CallbackPanel will execute the JavaScript you rendered (in this case window.alert('hi!');).

Thanks

Other ways include rendering html input element, using our CallbackPanel's ClientSideAfterExecute event handler, etc.
