    [CLOSED] Dropdown Field List Position

    Hi,
    How can I set the position of Dropdown Field List from bottom to top?

    I am loading a page in iframe and in the bottom of tht page there is a DropDownField which has a panel as its component. Since there is no place, an ideal behaviour shud be to show the panel on top of dropdownfield, but instead it shows at the bottom, resulting in scroll bars.

    Check attached image.

    Thanks,

    Hi,

    DropDownField has ComponentAlign property (ComboBox has ListAlign)

    Unfortunately, it's not so informative.

    .ComponentAlign works fine in the following example.

    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">

</head>
<body>
    <form runat="server">
    <ext:ResourceManager runat="server" />
    <ext:DropDownField runat="server" ComponentAlign="bl-tl?" Y="300">
        <Component>
            <ext:Panel runat="server" Height="200" Width="200" />
        </Component>
    </ext:DropDownField>
    </form>
</body>
</html>

    Could you clarify why do you use LazyMode="Instance" for Panel?

    It breaks DropDownField logic. Please remove this property, and things will work fine.

    Hi,
    The panel and its dropdown component are in hidden parent Panel. They are not instantiated by default and I need the values inside the panel which are in a checkbox group even if the parent panel is hidden.

    Please set LazyInit="false" for DropDownField.

    I think you did not notice, but there is already LazyInit=false in the code sample I provided. It still does'nt work.

    Thanks

    Hi,

    If remove LazyMode from the panel (as Daniil mentioned) then all works as expected
