    Hi,

    Did you try just
    Ext.net.DirectMethod.request('DoSomething')
    ?

    It should work.

    If the issue persist please provide us with a sample code like the following one.

    Example
    <%@ Page Language="C#" %>

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

<script runat="server">
    [DirectMethod]
    public void TestDirectMethod()
    {
        X.Msg.Alert("DirectMethod", "Hello!").Show();
    }
</script>

        <Listeners>
            <Click Handler="Ext.net.DirectMethod.request('TestDirectMethod');" />
        </Listeners>
    </ext:Button>
    </form>
</body>
</html>

    Hi,

    Well, thereoretically it should works. Just I suggest to use 
    type:'load'
    also you can add failure handler to see the problem
    <Click Handler="Ext.net.DirectMethod.request('DoSomething',{url:'Page.aspx', type:'load', failure: function(error){Ext.Msg.alert('Error', error);}})" />
    But IMHO it is bad design to call cross page direct methods. If you have logic which must be shared then you can use webservice (it is more effectively)

    hi vlademir , "type : load" does not solve my problem . also it doesn't show any error. in debuging , result of this call process is undefined. i can't use webservice because i refresh UI in method.

    Hi,

    I just tested it with success.
    Please look at the following example.

    If the issue persist please provide us with a sample code.

    Example Page
    <%@ Page Language="C#" %>

<%@ 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">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Ext.Net Example</title>
</head>
<body>
    <form runat="server">
    <ext:ResourceManager runat="server" />
    <ext:Button runat="server" Text="Test DirectMethod from another page">
        <Listeners>
            <Click Handler="Ext.net.DirectMethod.request('Test', {url: 'AnotherPage.aspx'});"/>
        </Listeners>
    </ext:Button>
    </form>
</body>
</html>
    Example Another Page
    <%@ Page Language="C#" %>

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

<script runat="server">   
    [DirectMethod]
    public void Test()
    {
        X.Msg.Alert("AnotherPage", "Hello!").Show();
    }

    ok. i have a page( page1) and it contains two user control (i.e uc1 & uc2).uc1 contains ext grid and some ext controls . i open uc2 in ext window and it contains some ext field controls and a panel to show page2 in iframe . in page2 , user do some crud processes and click save button . after click save button , i want to refresh grid in uc1 and some updates on controls. so

    i have method in page1.

    [DirectMethod]        
        public  void AfterSave()
        {
             //this method call the uc1's method to update UI.
        }

    in page2 save button click

    parent.Ext.getCmp(parent.document.ctlKuralEditorWindowId).close(); // to close uc2's parent window.
Ext.net.DirectMethod.request('AfterSave', { url: '~/Pages/Users/Provizyon/ProvizyonKural/default.aspx', type: 'load', failure: function (error) { Ext.Msg.alert('Error', error); } }); // to refresh uc1's grid and control in page1
    as a result AfterSave method isn't called from client side.

    thanks for interest.

    Hi,

    You have to call direct method right context
    parent.Ext.net.DirectMethod.request('AfterSave', { failure: function (error) { Ext.Msg.alert('Error', error); } });

    Hi,

    Could you provide us with a simplified sample code reproducing the issue?

    You can base on the following code which works fine.

    Example
    <%@ Page Language="C#" %>

<%@ 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">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Ext.Net Example</title>
</head>
<body>
    <form runat="server">
    <ext:ResourceManager runat="server" />
    <ext:Button runat="server" Text="Test DirectMethod from another page">
        <Listeners>
            <Click Handler="Ext.net.DirectMethod.request('Test', {url: 'AnotherPage.aspx'});"/>
        </Listeners>
    </ext:Button>
    </form>
</body>
</html>
    AnotherPage.aspx
    <%@ Page Language="C#" %>

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

<script runat="server">   
    [DirectMethod]
    public void Test()
    {
        X.Msg.Alert("AnotherPage", "Hello!").Show();
    }
</script>
