    [CLOSED] Parameters or variables sent from parent page

    I need to use parameters or variables in child page, these parameters are sent from a parent page, for example:

    this is my application, the home page (parent page) is composed of a viewport with a TabPanel in the center and on the left menu:

    Click image for larger version.  Name: Captura.JPG  Views: 125  Size: 41.5 KB  ID: 5572

    By clicking on any of the menu options, for example I click on "Contracts", shows the following:

    Click image for larger version.  Name: Captura2.JPG  Views: 143  Size: 95.3 KB  ID: 5573

    shows the catalog of contracts (child page), it and each of the menu items are aspx files

    I want to click on the contracts or any other, send a parameter that can be used in the codebehind of contratos.aspx (child page)

    I hope to be clear in my problem and I hope you can help me,
    thanks!

    If you're loading the inner page into an iframe, how about send the extra information as a parameter of the Url?

    maybe I did not explain well,

    in the codebehind of page contratos.aspx, I need to use a variable that contains an identifier of the option contratos.aspx, that identifier or parameter is extracted from the database,

    I will use this parameter to validate permissions on contratos.aspx.

    Permissions to modify, to add new record, to delete a record, etc.

    Hello!

    I don't quite understand you.

    You have a Parent Page which has some parameter and you want to use this parameter on CodeBehind side of second page when it opens? If I'm right please try the following approach:

    ParentPage.aspx
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        Window win = new Window()
        {
            ID = "Window1",
            Title = "Child Page",
            Width = Unit.Pixel(400),
            Height = Unit.Pixel(200),
            Modal = true,
            AutoRender = false,
            Collapsible = true,
            Maximizable = true,
            Hidden = true,
            Loader = new ComponentLoader
            {
                Url = "~/ChildPage.aspx",
                Mode = LoadMode.Frame,
                LoadMask =
                {
                    ShowMask = true
                }
            }
        };
        
        // Here you can put any value
        win.Loader.Params.Add(new Ext.Net.Parameter("myparam", "Parameter from parent page", ParameterMode.Value));

        this.Form.Controls.Add(win);
    }
</script>

    hi - Regarding this Thread: The Solution above seems good if you only need to pass in a single parameter.

    Could you expand on this, and recommend a solution for passing more complex data to the child form?
    For example:

    Question: How would you suggest to pass a "HashTable" from parent page, into the child page?

    Hi @VirtualArtists,

    According to the fact that a request can transmit strings only. A HastTable should be serialized on the parent page and deserialized on the child page. It looks the only solution if you need to send that parameter through a request. Another solution could storing the parameter somewhere on the server, for example in the Application global object.

    I think it is a candidate for a new forum thread. Please start. If you feel the threads are related, please feel free to cross-link between the two.
