    [CLOSED] Form authentication caused a problem with LoadControl and returning field values

    Repost of I question I asked 2.x help


    I'm having problems with the LoadControl method in combination with form authentication.
    When I use form authentication my input fields are not filled with the Request.Form values.

    How do I get this code to work in combination with Form authentication.


    I'm using Ext.NET Pro version 2.5.2.10712


    In my code I'm using a custom control, but I have managed to reproduce the symptoms when dynamically creating a window.


    Request body with <authentication mode="Forms">


    The value is pressent : 'UC_UCrfText=MyValue' but not set in the TextField

    The 'UC_UCrfText=MyValue' is pressent and also set in the TextField.

    When using this in the web.config I cannot get the Textfield value
    <authentication mode="Forms">
        <forms loginUrl="~/WebForm.aspx" />
        </authentication>
        <authorization>
    </authorization>

    Thanks,
    Marc

    Hi,

    Did you try to recreate your user control in Page_Init instead Page_Load?

    Thank you,

    Moving the code to the Page_Init and removing the check IsLoaded fixed the problem.
    Will need to investigate if I need to check that the control is already loaded.

    Its still strange why changing the authentication mode changes ASP.NET behavior.


    protected void Page_Init(object sender, EventArgs e)
    {
     //   if (IsLoaded())
     //   {
            this.LoadUserControl(controlUrl);
     //   }
    }
