    [CLOSED] DirectMethod function: I wish cascading calls and receive returns.

    Hi!

    I have a main page with two ext:panels. In each panel, I'm loading a page.
    The idea is that the first page contains filters and the second page contains a grid with data.
    I'd like that before grid refresh, is received the selected filters in filter page.

    But I do not know how to get the result of the function.
    I call the directMethod with Ext.Net.X.Js.Call.

    The grid Page call a directMethod function in Main Page and Main Page call a directMethod function in Filter Page.

    I don´t following the example in https://examples2.ext.net/#/Events/D...hods/Overview/ because I need that result is returned in a sub or function, because I need work over the return.

    I made a simple sample.

    Main Page (test50.aspx)
    <%@ Page Language="vb" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">
    <DirectMethod()>
    Public Function GetValueInTest50() As String

        Ext.Net.X.Msg.Alert("GetValueInTest50", "Here, I want call the directmethod function in Test51 aspx Page and and return the result to Test52 aspx Page.").Show()
        Return ""
    End Function
    
</script>

    I am affraid that such scenarion is not supported by DirectMethods
    I suggest to use DirectMethod/DirectEvent when it is required only (when server side handling is required)
    Extract value from a field can be accomplished on the client side without direct method

    Is there any way I can do what I want?

    You have to do all on the client side (as much as possible), extracting field values, set text to label and etc, all of that can be accomplished on the client side via javascript

    DirectMethod si not designed to call another direct method

    I do not have experience in JavaScript, but I can find the web the commands.

    But I need a way or example on how to access the components of a page from another page, in cliente side.
