    [CLOSED] UserControlLoader getValue from DirectMethod

    I want to set [DirectMethod] strA() in a.aspx to txtb in b.ascx
    I don't know Button1_Click content in a.aspx
    I don't know how to get strA() from a.aspx in b.ascx

    pls help me, thanks very much.

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

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

<script runat="server">

    protected void Page_Init(object sender, EventArgs e)
    {
        UserControlLoader ul1 = new UserControlLoader();
        ul1.ID = "uc1";
        ul1.Path = "b.ascx";
        Panel1.Items.Add(ul1);
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack && !X.IsAjaxRequest)
        {

        }
    }

    [DirectMethod]
    public string strA()
    {
        string str1 = "a-Value" + DateTime.Today.AddMonths(-1).ToString("yyyy-MM-dd");
        return str1;
    }

    protected void Button1_Click(object sender, DirectEventArgs e)
    {
        UserControlLoader ul1 = X.GetCmp<UserControlLoader>("uc1");
        ul1.Render(); //??? I dont know how to refresh
    }
</script>

    Hi @CPA1158139,

    You could do the following in the user control.

    Example
    <ext:TextField 
    ID="txtb" 
    runat="server" 
    FieldLabel="txtB" 
    LabelWidth="25">
    <Listeners>
        <Render Handler="var field = this; 
                         App.direct.strA({
                             success: function(result) {
                                 field.setValue(result);
                             }
                         });" />
    </Listeners>
</ext:TextField>
    As for refreshing a UserControlLoader, I would wrap it in an additional Container:
    <ext:Container ID="Container1" runat="server" />
    Container1.Items.Add(ul1);
    and call
    this.Container1.UpdateContent();
    But it is not working. Probably, a defect in Ext.NET. We will try to fix.

    As a solution you can do the following.

    1. Place this into the Panel1's Items.
    <ext:Container ID="Container1" runat="server" Layout="AnchorLayout" />
    2. Use these methods:
    protected void Page_Init(object sender, EventArgs e)
{
    this.Container1.ContentControls.Add(this.LoadControl("TestUC.ascx"));
}
    protected void Button1_Click(object sender, DirectEventArgs e)
{
    this.Container1.UpdateContent();
}

    It works fine.Thanks very much!

    Sorry, by the way,how to getValue without TextField? I get a error msg


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

<script type="text/javascript"> 
        App.direct.strA({
            success: function (result) {
                alert(result);
            }
        });
   
</script>

    I get a error msg
    Please always post the error and Exception messages.

    I guess there is something like "App.direct is undefined".

    It means that the script executes too early, before creating of the App.direct namespace.

    You can use:
    <script>
    Ext.onReady(function() {
        App.direct.strA({
            success: function(result) {
                alert(result);
            }
        });
    });
</script>

    Sure,Daniil,you are great.
    I understand Ext.onReady is used to initialize. How to render?

    How to render?
    How to render what? Can you provide some more details, or an updated sample demonstrating the scenario you are attempting to get working.

    It has been fixed in the revision #6021.
