    Spring.NET validation integration

    Hi,

    I do realize this is a bit of a big subject but here goes:

    My current project requires me to work with the Spring.NET framework. This framework provides validation including a control. Since this control does not subclass Coolite.Ext.Web.Component I cannot use it inside an AnchorLayout. Instead Spring.NET comes with a ValidationError control that subclasses AbstractValidationControl that subclasses System.Web.UI.Control.

    Requirements are:
    - Must participate in ext layouts
    - Must be able to display/hide and change message after an asynchronous callback

    Unfortunately this seems tricky since both these requirements seem to depend on subclassing a concrete class rather than implementing an interface. At the moment it seems easiest to write sort of an adaptor control that subclasses Coolite.Ext.Web.Component and references a Spring.Web.UI.Controls.AbstractValidationControl that defers rendering of validation errors to the Coolite.Ext.Web.Component.

    Any thoughts or pointers on this?

    Regards,

    Dirk Louwers

    Hi Dirk,

    What about if place to AnchorLayout the Coolite Panel, set for panel Border="false" and no header. Then you can put your control to the panel body.


    Is it acceptable solution?

    Hi,

    That would solve part of the problem, but would it also allow for asynchronous callbacks to update the message and toggle visibility? I am striving for as tight an integration as possible.

    Best,

    RE: Spring.NET validation integration

    I've ran some tests to see if at least it can be used inside a form layout but that causes problems. I need to multiple controls on a single line inside a form layout with a single label. The anchor can only contain a single control. Therefore I have used a panel with a 3 column table layout inside. The third cell contains a panel containing the validation control.

    This leaves me with no way to set the label, because the anchor doesn't pick it up any more because the panel doesn't have a FieldLabel property. I think anchor should have a FieldLabel property to set the field label in case the control contained doesn't have the FieldLabel property (like Panel).

    Best,

    Hi Dirk,

    Please see the following example which shows how to place several fields in one line

    Hi Vladimir,

    I have seem these examples. None of them illustrate what I need. I need multiple controls with a single label. All the examples illustrate one label per control situations.

    Hi Dirk,

    You can hide labels for controls which don't require show a label
    Please see the following example
    <%@ Page Language="C#" EnableViewState="false" %>
<%@ Import Namespace="System.Globalization"%>
<%@ Register Assembly="Coolite.Ext.Web" Namespace="Coolite.Ext.Web" TagPrefix="ext" %>
