I read the Supporting Focus Within Your App and I'm still missing how can I shift focus to some custom view programmatically.
I know there are setNeedsFocusUpdate and preferredFocusedView methods. However, I'm looking for a method like [button bringIntoFocus].
Does something as simple as this exist?
There is no such way, it all needs to be indirectly done. You configure the Focus-chain from the higher up view (or view controller) to end up on the view you need to be focused. So yes, you need to check state at every view/VC in between and grant preferred focus conditionally.

I need to implement a drop-down which has a delete 'X' option next to each option item. Somewhat like the image shown below.
The drop-down is populated dynamically and I need a way that does not inlvolve using list as an alternative.
EDIT: The icons next to each dropdown item refers to 'Edit'/'Delete'
You cannot put a checkbox into the usual <select> or multi-select HTML element.
However, here is another question where several good options are discussed.
This looks like the most useful and best suited to your purpose:

UPDATE:
Given that you need both the HTML markup and the javascript to make it do what you want, you have two (possibly 3) steps to do:
This answer provides a good example of how to create the custom-rolled <select> control.
This answer shows you how to replace the checkbox created in step 1 with an icon/image of your choosing.
The javascript to remove the x'd <option> is very simple:
$(this).closest('option').remove();
IF you also need to save these results, then you also need to learn:
4a. Server-side SESSIONS (so that each user's customizations are saved for them)
4b. A login system, so you know for which user to save the current customizations.
4c. Just the basics of how to use a back-end database, such as MySQL/MariaDB, in which to store the user customizations.
4d. AJAX - so you can schlep info to the back-end for insertion into the database without refreshing (or navigating away from) the current page. AJAX replaces the ancient and no-longer-used <form> construct. Frankly, once you've used AJAX a couple of times, you'll never go back. Totally easy.
If you are in a bind and need someone to create the whole thing for you, I refer you to one of these websites - I have used such services myself and can recommend them.
We have built custom state saving functionality into our web app, based largely on the "Screenshot Manager" extension that Philippe created. We are having an issue with selection, wherein some components that where hidden when the state was saved are being shown when the state is loaded. I have replicated it on viewer.autodesk.io with the vanilla states manager code.
To be precise, components already visible in the viewer that are hidden by CTRL-clicking them on the model browser initially disappear in the viewer. However, when you save this state and then recall the state at a later time, the components hidden in this way re-appear.
Can you please investigate - is this a bug in the states manager code (we had a look but can't find it - the hidden components are being recorded in the state) or in the viewer itself?
Thanks,
Chris
I check what happen when you select components, those 2 states are incompatible: the child gets hidden but the parent gets isolated, hence it is displaying all its children and hide the rest of the components in the model.
In order to get the behavior you "would" expect, you would need to hide all components without isolating the parent sub-assemlbly, then create your first state, then hide the child, create your second state. You may achieve that by writing your handler when clicking a browser node. For that you would need to implement your own ModelStructurePanel.
I've got a basic example which can help you getting started:
ModelStructurePanel
I will take a look at the click handler and add an example there. For the time being, you can check in the source of the viewer3D.js which methods you need to overwrite.
Hope that helps
We are porting our MFC based client to Dojo. Is there any widget similar to listbox control. At present I am using DataGrid, but that seems heavy and overkill for our purposes. Alternatively what is best widget to replace listbox.
Update: I have already looked at dijit.form.multiselect, and I dont think that meets my requirement. MFC Listbox typically looks like this. I dont see (or rather dont know) how to replicate this with multiselect. It is possible that DataGrid is best fit for the control.
If you use dojo 1.7, take a look at the new DGrid.
For an example looking like yours, go to the tests page and pickup the Selector.html example.
Here are some options depending on which part of the ListBox you want to create:
dijit.Dialog to create a basic dialog box.
dijit.form.FilteringSelect to create a drop-down with your options (single select only).
You could also use radio buttons or checkboxes for your options depending on whether multiple selections are allowed.
I have a basic ASP.Net MVC 3 application which has a number of controllers and a number of actions (and subsequently views)
A common feature of the application is to show a pop-up dialog window for basic user input. One of the key features of this dialog process is a faded mask that gets shown behind the dialog box.
Each of these dialog window controls is in a separate Partial View page.
Now, some view pages may use multiple dialog boxes, and therefore include multiple partial views in them - which as is would mean multiple instances of the "mask" element.
What I am trying to find a solution for is to only need to create one instance of a "mask" element regardless of the number of dialog partial views I include, and then the script in each partial dialog will have access to this element (so basically it just needs to be on the page somewhere)
The only real idea I have come up with so far is to add the "mask" element to the master page (or in the original view page) and this will mean it only gets added once. The problem here is that it will be added even when it is not needed (albeit one small single element)
I can live with this, but I would like to know if there is a better way to handle these kinds of scenarios?
A quick idea that came to mind is some kind of master page inheritance hierarchy, So I may have a DialogMasterPage that inherits from the standard current master page. How does that sound for an approach?
Thanks
To do something like this, where each module can register their need for a certain thing in the master page, you can use HttpContext to store a flag of whether you need to write the mask div, and just set that property in each partial. At the end of the master page, if the flag is set, you can then write the mask div if its set to true.
Obviously to make this cleaner you could wrap it all in an HtmlHelper extension or something.
My initial thought is for you to use something like jQuery UI where it handles the masking for you or if you are using something custom you can load the content for the dialog via ajax then show it in the single dialog on the master page.
I was using a combobox on my search form to select whether to consult or modify a record.
To make it more user friendly (IMO), I put a togglebutton on a form, which controls the .AllowEdits property of my form. This way you can easily switch from reading to writing.
However I run into a problem; once .AllowEdits is switched to false, the togglebutton is not clickable
anymore !
What are my options ?
You must use a command button instead. It will not get locked.
You will however run into similar problems with other controls like a combo box you would use for quick searching a record. If you have that problem, use the solution here to lock/unlock all your bound controls.
