We have a dialog inheriting MvxDialogViewController containing two Sections - TheRadios and TheList.
In response to the user changing the radio within TheRadios, we repopulate TheList (in the view model).
How can we bind a Section of a MvxDialogViewController to a dynamic list?
Looking through all the mvvmcross samples I couldn't find an example of this being done. I considered inserting a MvxActionBasedTableViewSource into the relevant Section's TableView but the property is null.
If you do want to bind a list within a Dialog section to a list, then I believe this extension may help you - https://github.com/asednev/MvvmCross.AlexeysExtensions
I'm afraid it is for vNext rather than v3 currently, but I think it should port very easily - I think the only changes needed would be just a few namespace changes (if you do port it, then please send them a pull request with the changes)
Alternatively
it is open source, so it may give you alternative ideas
you could consider using a custom or manual binding to INotifyPropertyChanged in order to achieve the table changes you are looking to achieve

My scenario:
The xpage ( document content ) has a complex structure. I have a 1st button which opens this xpage, having in the postNewDocument:
Contr.replaceItemValue("txt_codformularmain","01") // I use this field as a flag.
Now, there is another button which compose the same xpage ... but in this case, I do want the xpage to be different, in other words to have some additional / showed fields.
I could add another code at the postNewDocument, like this:
Contr.replaceItemValue("txt_codformularmain2","01")
Later on, in some views I will filter the listed documents by this 2 fields: some views will be listing the documents where txt_codformularmain=01, other views for txt_codformularmain2=01, and so on.
All the fields are on the same form element. ( I could create easily 2 different xpages, with 2 document contents, but in the form Properties at onOpen and onWebAccess settings, I can add only one xpage )
But, I think it isn't the best approach for this. Because in both cases, postNewDocument takes place, and both fields are having the value 01.
In classic lotus notes programming, I had used only one field ( flag ) and for every different button, inside the button's code I just changed the field value: 01, 02, and so on, before the newDocument had been composed.
Should I use another/ a better approach?
I might go for creating a new form with the fields needed there, and creating a new XPage binded to that form...
dominoDocument.isNewNote() will tell you if it's a new document or not. You can compute visibility based on that.
If it's based on a field value, then again set the visibility based on what the value should be for the panel to be visible - instead of getComponent().getValue() use dominoDocument.getItemValueString() assuming it's a Text field for best practice. In the onblur event of the control that's bound to the field you're checking against, trigger a partial refresh. You will need to amend the default partial refresh settings if there is validation on the page.
Once you're comfortable with that technique, start thinking about using a dataContext to hold whether or not an area should be visible, and referencing that dataContext variable in the rendered property. The benefits of this are not only performance, but youo can give a better variable name to the dataContext to make it clearer when supporting the application what the logic is behind it being visible. For someone supporting the Notes Client app, for example, it's unclear without hunting what state "01" or "02" means. Descriptors like "newDoc", "published", etc have an advantage there.
Another method of optimisation would be to use a Dynamic Content control.
But it sounds like your XPage is going to be complex enough without adding more complexity at this stage.
I have a fairly straightforward and common use case. A panel, in which resides a repeat control. The repeat control gets its content from a view lookup by key. Below that repeat control is another panel. This panel has a data binding to a new notesdocument. The panel has a couple of fields on it for the new document and a submit button.
It all works, however after submit (presumably in the "postSaveDocument()" event) I want to call back up to the repeat control and have it re-perform its lookup and refresh its content.
I'm looking to understand syntactically, how I can reference the repeat control and its properties and methods from elsewhere on the document -- and secondarily (though I can look this up once I get the first part figured out) what the refresh() method would be for that that repeat control.
Ideally, I think its something like: xp:page.repeatcontrolname.refresh() -- though I know that isn't right.
I'm sure once I see an example, it will apply to a myriad of other things.
Update :
I discovered that the repeated elements were actually refreshing but I wasn't seeing a new entry added to the list. The reason, ultimately, turned out to be that to add another entry to the repeat list I needed a new "control" -- but I'd checked that box (on the repeat control) that said "Create Controls at Page Creation". It was preventing my XPage from creating another entry for the new document to display!
This article explains the syntax for doing what you describe:

I have a feeling that this one captures the actual use case.

The key setting that people tend to miss is "ignoreRequestParams".
Andrew,
The 'XSP.PartialRefreshGet' call was broken in Domino release 8.5.3 which results in the '_c9 is undefined' error.
Have a look at the article posted by Tommy Valand:
http://dontpanic82.blogspot.com.au/2012/03/patch-for-bug-in-xsppartialrefreshget.html
Basically to work around the problem a second argument is required to be passed to the call, for example:
XSP.partialRefreshGet("#{id:ExistingDevicesList}", "")
This is what I am trying to do, when my apps load, user is presented with a bunch of options ( These options are coming from a server) and when user selects one of those options I have to create a new tab bar controller with number of tabs, their name, their layout all coming from a server in the xml format. So the first question is it possible to do this in iphone, that is create all the view controller programmatically on the run time, if yes can you please point me to some reference, i have been searching in google, but may be my search terms are not good, I am not getting back any results.
Of course, it's possible. Anything that can be done using IB can also be done in code. In your particular case, you have to subclass the UITabBarController class and then use the viewControllers property to populate the bar at runtime, depending on your XML.
Please refer to the class reference at Apple.com for more information.

I've got a requirement to hold a DateTime value in a SharePoint field but to customise the display in a list view so that it shows as a mmmm string. The underlying value must remain as the DateTime so the sort is chronological rather than alphabetical.
So I think that a Custom Field is the way to go, I'll also get some added benefit in restricting the user interface to a month picker so even if there is another solution I'll likely go down this route to get that.
I've read that I can apply custom templates to the new, edit and display actions but I can't seem to find anything saying how to alter the list view (display patterns doesn't seem to be enough).
Anyone got any ideas?
Thanks
Justin
I dont know if this is what you are looking for but I have used a solution with a custom fieldcontrol that overrides RenderFieldForDisplay like:
protected override void RenderFieldForDisplay(HtmlTextWriter output)

Is there a way to handle the DropDownSelectedIndexChanged for list item new form.
Let say I have a custom list named Temp having Title, Products (which is a DropDownList) and Color Shade (which is a TextBox).
When I create a list item I want to select a product from DropDownList and on the selected index changed I want to write the
business logic such as fetching the row from Color Shade list and bind the data to TextBox of Color Shade. Now I can say ok so that
a list item will be created. Is it possible using VS 2008 sharepoint object model.
you could add a custom control to your masterpage which resursively traverses your control tree (start from this.Page) to find your dropdown and attaches the event handler (which itself is defined in your custom control). Also set the AutoPostBack property to true on the dropdown once you found it.
In terms of getting a reference do your textbox within your eventhandler, you could also apply the same approach of traversing the control tree.
note, you need to ensure that event handler is attached before eventhandlers are run.

I am not sure if I understand what you mean.
An alternative approach, and probably less work, would be to use javascript (I would recommend using the jQuery library) to automatically populate your textbox when the selection of the dropdown changes. Everything would be done clientside.
Jaap
There are some third party components that do this sort of thing as custom column types, but if you're developing from scratch you'll probably find it a lot easier doing a custom form. If you do a fully custom version of newform.aspx, you'll still be using the standard new item menu.
If you try to modify the standard controls you'll run into issues like security errors if the submitted value wasn't in the original list.
If you don't want to write your own saving code, hiding the standard new form with css and modifying the values with javascript from your custom control can work quite well.
