Render Widget as HTML in Code Behind - kentico

I have come across a situation where I'm needing to retrieve the rich text content of a page type column, and return that data/HTML as it would appear on a rendered page. A custom web part then serves aggregated data as nodes of XML or JSON.
For the most part this was easy enough in the code behind using DocumentQuery, however the problem is with widgets that have been inserted into the content.
My question is: How do I "render" a widget purely in code? Or even, what process is Kentico doing to render a widget that I might be able to reproduce?
I am somewhat familiar with the widget/web part/user control relationship, so I'm thinking a web part would need to be instantiated (somewhere, somehow) using the properties on the widget, and then accessing the RenderedHTML property of the web part.
Due to the format that widgets are stored in the data, I was hoping that they could just be Resolved with the MacroResolver, but that doesn't seem to be the case.
For reference, here is an example of how the out-of-the-box DateTime widget shows up:
{^widget|(jsuseservertime)False|(name)DateTime|(widget_displayname)Date+%26+time|(width)|(height)^}
Any input is greatly appreciated!

Have you checked this article http://devnet.kentico.com/articles/how-to-resolving-the-inline-controls? It is pretty old. But CMS.ExtendedControls.ControlsHelper.ResolveDynamicControls is available in newer Kentico versions. I think it might resolve you issue.

Proper Kentico object for non-user-editable block of static html/javascript

The Situation: I've got a mid-sized chunk of html/javascript that contains an authentication script/input (it's a text input, radio control, and a combo box and a few buttons). What it is is less important than the concept that it's a mass of static client side code that the marketing department can pretty easily accidentally the whole thing.
The Desire: I want the users to be able to add it as a whole to a page, but not be able to modify it. When something needs to change, I want to change it in one place and have it be changed on all the pages.
What I've Tried: Widget with a default text. It works, but feels wrong. Users can edit it, and if they do when I fix it one place it doesn't propagate to all the instances. I'm a bit of a Kentico noob, but it seems like there should be a better way to do this.
Also note: I'm using portal engine if that makes a difference.
A widget is the proper usage. What you make your widget inherit from is the key in this case. I'd suggest creating a new widget based on a static HTML webpart. This way you can set the static HTML markup and hide the property from the content editor on the front end. You can do this by going to the Properties tab of the widget and setting the visibility of the field on the form. Don't delete the field, just hide it. It should be a checkbox that says hide on public form or editing form.
** Edit **
As I read through my answer and comments, I realized I meant to say clone the static HTML webpart and set its default text to your javascript. Then create a widget based on that cloned webpart. The text will reside in the web part and will allow you to update it in one place later, if needed.
I will not do it this way because you will be not able to make changes in the future. You can better create a new webpart this can be an empty webpart and then create a custom layout. In this layout you can put you're code. In this way you can always change you're code in the future and then it will be changed on all the places where the widget is placed.
I'd use a new widget based on the Static HTML webpart (make the field read only or hide it as Brenden mentioned), but store the data in a new custom setting.
no coding needed (only a macro to read the custom setting)
able to edit the script on the fly on any instance in the settings module. If you have multiple of these settings you won't need to go through all kinds of widgets to adjust their default setting but find them on a central place.
Cheers!

In this case I think it makes sense to create a custom web part to store all your code in it and use it that way. If you want to achieve it without creating a custom web part, you have to store the code in some non-web part and not widget specific object. I like the suggestion of creating a custom setting. You can then access this custom setting via a macro. This macro can be used as a default property of a newly created web part (inherited e.g. from the static text web part, you'd use the text property). You may as well create a widget out of it. Another approach is to use Kentico localization keys as a workaround. you can create a key in the Localization application and access it again, via a macro, e.g. {?customkey.myhtml?}. The approach with a custom setting however sounds cleaner to me.
This syntax should be working to access a custom setting value via macro:
{%Settings.CustomSettings.xxx%}
{%Settings.CustomSettings["xxx"]%}
{%Settings.CustomSettings.GetValue("xxx")%}

Command Not Handled Exception

I'm new to Domino Designer. I'm trying to modify an existing application which is running on a remote server. I create a blank xPage and view in browser and it works. I add a label and view in browser and it works. I add a combo box and setup a data source for my xPage. The data source is in the current application and I'm using a view. I setup my combo to point to that data source and specify BindTo value. I view it in browser and I get Error 500 "HTTP Web Server: Command Not Handled Exception" I can open the view that I've used and see all the data in the view. I can even add, edit, and delete from the view.
Ideas... Thnxs in advance.
Additional Info. I've added a "View" from "Container Controls" and used the same data source and the same view and it also works in the browser.
The error being printed is:
javax.faces.el.PropertyNotFoundException: Error getting property 'CompanyName' from bean of type lotus.domino.local.View

This was already answered in the comments, but I want to write a better answer.
The problem in this case is that a view data source is being used for editing a document. Directly, this is not a possibility, though there are a few great ways to get around this. The first way, and my favorite, is to use an inline form. I think the Extension Library Demo database offers a few great examples of how to go about doing this. One way is to use a tooltip dialog. Another way is an inline form. A repeater is used and for every row in the view, a hidden panel can be made which contains the document data source and all field which are required to be changeable. By clicking on a button or link, the panel is made visible. This is my favorite variant because it is simple, quick, and generally looks great.
Another way to go about this is to have a view data source only, but use scripts to retrieve the document and set the values in the background and then save and release. It all depends on what you are trying to achieve.
My main recommendation is to look at the ExtLib demo and take a look at what they are doing there.

Reusable edit form in Apache Wicket

I have a simple ContactEditPanel which contains a form and a number of textfields. Up until now I included an AjaxSubmitLink in this panel which, if the form content is valid, saves/updates the Contact instance contained in the Panel model. So far so simple. However now I'd like to remove the link in order that I may, depending on the context in which I use the ContactEditPanel, place the submit link at different levels of my overall component hierarchy. For instance in one context I'd like to use to flip between ContactEditPanel and ContactViewPanel with a bar of actions above the current view (edit | save , cancel). Another context would be to use ContactEditPanel in a standalone way (maybe part of a multi-step process) with just a save link below.
I was contemplating refactoring my ContactEditPanel to extends FormComponentPanel rather than Panel as described here but I'm not sure whether this is the right approach and I'm having trouble wrapping my head around this.
Any help would be most appreciated!
Many Thanks,
A
Your using the panel like a FormComponent so extend FormComponentPanel, it will allow you to keep all the validation you write contained to the component and also allow you to reuse it as you wish.
Just think of it as you've created a new FormComponent, like a TextField or DropDownChoice.

In XPages Mobile App / Mobile Control, how to make picklist

I have two pages, one page for input, another page for the options, how to send value form page to another page on xPages Mobile Controls, or is there another way to make like this.
See my sample page:
1. Page 1:User Input
http://i1248.photobucket.com/albums/hh490/dannysumarnach/page_1_form_user_input.jpg
Page 2:Picklist
http://i1248.photobucket.com/albums/hh490/dannysumarnach/page_2_user_choice_PickList.jpg
note: the built-in typeahead not posible
Regards,
Danny
The in built type ahead is missing the dojo tundra.css file when using the single page app control. This file comes with Dojo its just not being included. Import this file to get the type ahead to work.
I'm unsure as to what you mean about passing value from one page to another, you can submit data to a document and open it in another page, add it to a scoped variable, add a parameter to the URL. All of these options will work.
Have a look at my blog post on this topic. There are a couple of gotchas to get around, most notably, ensuring the the page with your document datasource gets recalculated at the correct time. I'm working on a NotesIn9 on it.
Part 3 covers a couple of amendments to get it working with existing documents and includes a sample page that will work in the Extension Library Demo db. Note the extra view that needs to be created and other details in Part Two.

jsf popupwindow with a datatable

I have a form which one of it's fields is a code and description, also a button for opening a popup window that contains a list of all of the available codes.
when the user double clickes a row from that table i want to set these values to the code and description. - how can this be done?
Another question, I want to create this popup and table to be initialized dynamically - by that i mean that if i have a few forms in my application, when ever i have a field which has a description i want to be able to open this popup and to see the available list for that field. (every field can be from a diffrent table). is it possible to create something like that? if so, how?
Any help will be appritiated,
Thank's In Advance.
Yes, it is possible. Even more, many component libraries have ready to use popup/dialog components, such as RichFaces with <rich:popupPanel> and PrimeFaces with <p:dialog>.
If you do not want to use a component library for some reason, you would need to create a custom component for this which generates basically an absolutely positioned HTML <div> element with a CSS overlay which get shown/hidden by JS on a particular click/action. The HTML/CSS/JS part should be relatively simple if you are familiar with those languages. The JSF part is somewhat hard if you have never created a custom component before, but it should be possible with a composite component as well, so you could also just create one with pure XHTML. The updating/refreshing can just take place by the usual <f:ajax> means.
