    Hi,

    All fields (Ext.Net.Field inheritors) have the client side .isValid() method.

    validation

    how can I test whether a control can be validated or not? I ask this because a Panel I can not call the isValid ()

    You can use the following code:

    if (c.isValid) {
    c.isValid();
}

    continuation

    I created the function below but when I call the method validCtr gives error. Where might be the problem? The call is validCtr (panel1);

            Ext.onReady(function () {
            var isValidControls = true;

            var validCtr = function (container) {
                container.items.each(function (controlId) {

                    if (controlId.isValid) {
                        if (!controlId.isValid()) {
                            isValidControls = false;

                        }
                    }
                    //if (controlId1.getXType() == "panel") {
                    if (controlId.id != container.id) {
                        if (typeof (controlId.items) == "object") {

                            return validCtr(controlId);

                        }
                    }


                });

            }        
           
        });

    I have tested your code and it appears to be working fine.

    Why do not you want to use .cascade() method? I would extremely reduce validation code.

    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>

    <script type="text/javascript">
        var validate = function (container) {
            container.myIsValid = true;
            container.cascade(
                function (c) {
                    if (c.isValid) {
                        this.myIsValid = c.isValid();
                    }
                },
                container); 
            alert(container.myIsValid);   
        }
    </script>
</head>
<body>
    <form runat="server">
    <ext:ResourceManager runat="server" />
    <ext:Panel ID="Panel1" runat="server">
        <Items>
            <ext:NumberField runat="server" AllowBlank="false" />
            <ext:TextField runat="server" AllowBlank="false" />
            <ext:Panel runat="server">
                <Items>
                    <ext:NumberField runat="server" AllowBlank="false" />
                    <ext:TextField runat="server" AllowBlank="false" />
                    <ext:Panel runat="server">
                        <Items>
                            <ext:NumberField runat="server" AllowBlank="false" />
                            <ext:TextField runat="server" AllowBlank="false" />
                        </Items>
                    </ext:Panel>
                </Items>
            </ext:Panel>
        </Items>
    </ext:Panel>
    <ext:Button runat="server" Text="Validate">
        <Listeners>
            <Click Handler="validate(Panel1)" />
        </Listeners>
    </ext:Button>
    </form>
</body>
</html>
