I have a few draggable objects which I would like the user to drag around and then press "save" and return to the page the next day to drag them some more.
The draggable objects include dynamic html with event handlers etc.
I want to store these objects in the DB and then be able to reload them.
What would be a good approach to achieve this?
One possible way I came up with is to store all DOM code within a container div, in the DB as a string, and then insert it into the page and run scripts to add new event handlers for the specific elements...
I guess storing them as a string is the best solution. Just put the column type "Long text" in the database!

I have TextField and onChange function it filters ListView, so is it better get whole item from table and save them in list then when change text filter that list or open stream get data from table every single change in search TextField?
I have lists in my app with elements, is it preferable when I go to another page or when I don't use the items, clear them every time or it is ok, it doesn't affect the app?
I have a view of entities which are being displayed based on an entity type filter. I now need to reorder these and would like to use the built in 2sxc functionality to do this, so I have a created a new view of the data using the "module data source" so that the ordering will work.
But how do I now make all of the existing entities of the same type (definition) appear in this new view? The view now displays one item by default and I can replace that one item. But how do I add multiple existing items? I need the Entity ID's to remain the same for Query String usage and SEO.
Thanks, hope the question makes sense.

I believe that you are asking "how can I add many items to an instance (module) manually, so that I can also sort them manually" - is this correct?
If yes, then you must make sure your template supports lists (checkbox in the template settings). This then gives you a [+] button; but you don't want to use that, as it would be for typing in new data. There's another button called "add an empty demo entry" which you'll see as a round (+) after pressing the more ... button once. Pressing this will give you empty entries, into which you can then replace existing items.
I have just started using visual studio c++ (2010) with windows forms, but have cannot for the life of me find out how to create new UI items in response to events. What I would want to happen is click a button, and have a new row, with a couple of text boxes and buttons appear, with onebutton to delete the row if I keep clicking, more rows will appear, named row0, row1 etcv. I looked at this page, (http://msdn.microsoft.com/en-us/library/aa984255(v=vs.71).aspx), about adding controls programmatically, but when I add a new text box inside a click event, the text box is only created inside the scope of the event (as expected!), but I want to be able to create it insde the newRow click event, but access it and . I thought of making a 'row' class, with row.text and row.deleteButton properties, and at each creation of a row, respective events will be created for button clicks and text edits.
Is there anyway to do this, ie a function that can be created that creates new objects by passing the required name?
The trick for this to work is that you need to have declarations outside of the event handler to keep track of the newly added UI components. In the link you've given the added TextBox is locally scoped within the event function, and this will be removed from the heap (i.e. memory) when the event is finished.
So one solution would be to add a list of UI components to your form, and then have the events add to or remove from this list of components. To get this solution working you possibly need to read up on lists of objects (or possibly dictionaries) and how to handle these.
Sorry for a rather general answer, but the question is also very broad... :)
Is it possible to push a view over the active view and remove that pushed view when we are done with it? (something like a slide panel?)
I'd prefer doing that to destroying and recreating view all day?
You can use a card layout to define multiple components and display only one of them at a time. Or maybe you're rather looking for a modal container that doesn't completely hide the content beneath it (but prevent to interact with it)?
I created a model with ~30 columns, so every time I need to edit or delete something in CRUD, I have to scroll to the rightmost to find the edit or delete button. Is it possible to move them to the first 2 columns in the grid?
Also, it seems the CRUD class is derived from "View" rather than "Grid", so the addPaginator() function does not work here. Is there any way I can separate the data into different pages in CRUD? Thanks
CRUD is a container for both Grid and Form. Depending on how the page is called, it will initialize a proper sub-element. To do something with grid, such as adding pagination, you need this:
if($crud->grid)$crud->grid->addPaginatior();
Also if you are looking to re-order columns, then this is what you need to do:
if($crud->grid)$crud->grid->addOrder()
->move('edit','first')
->move('delete','after','edit')
->now();
Edit button moves just as Romaninsh said, but I'n not able to move the delete button...
