I am not sure whether webix support this and I didn't find a workable code snippet to dynamically add/delete/udpate tree node and corresponding table rows in the treetable.
Don't know what you mean by "dynamic".
But yes, webix treetable allow "manual" add/delete/update of items :
See the documentation here : https://docs.webix.com/datatree__nodes_manipulations.html#addingnodes
Basic code to add item in treetable :
$$('treetable').add({value:'Hey !', state:'ok', hours:42}, 0, parentId);
See snippet for demo : https://snippet.webix.com/pcjwpwfs

I am using OData API to read data in my Fiori Application. The issue is, in Odata API, the latest data entry is at the end rather it should be at the top. How do i do that ie put my latest data on top.
You can use the $orderby to decide what order the data is returned in. See the docs for more info. This URL is an example of ordering (using the OData TripPin example service) that sorts by the LastName property:
http://services.odata.org/V4/TripPinServiceRW/People?$orderby=LastName
We can use this same process to order by a DateTime value or an ID value to get your latest entries at the top. For example, here we order by the DateTimeOffset field StartsAt putting the latest entries first:
http://services.odata.org/V4/TripPinServiceRW/People('russellwhyte')/Trips?$orderby=StartsAt desc

As mentioned before, you might have a look at server side sorting using “$orderby” as seen here.

You might also want to check out the following tutorial on Sorting:
“
items="{
path : 'invoice>/Invoices',
sorter : {
path : 'ProductName'
}
}"
We add a declarative sorter to our binding syntax.
As usual, we transform the simple binding syntax to the object notation, specify the path to the data,
and now add an additional sorter property.
We specify the data path by which the invoice items should be sorted, the rest is done automatically.
By default, the sorting is ascending, but you could also add a property descending with the value true inside the sorter property to change the sorting order.”
Please see here and here

This here might also be helpful:
“In this step, we will create a button at the top of the table which will change the sorting of the table.
When the current sorting state of the table is changed, the sorting state will be reflected in the URL.
This illustrates how to make the table sorting bookmarkable.”

Anybody know how to/or it is possible - create a Table with column specific order; configuration order which was before save - example in DB,
and uploaded at specific view on? also I wonder how to take generate this columns headers and content from POJOS class - beans.
Any good ideas?
setVisibleColumns
The Table::setVisibleColumns does double-duty:
Controls which columns are visible, and
Sets the order in which the columns appear.
Call Table::getVisibleColumns to see current ordering.
Doc
This is well described in:
Book of Vaadin > Table
Sampler > User Interface > Data Presentation > Table
Table API JavaDoc
Example Code
Basically, you need the code like this to control columns order and also set list of bean instances as datasource.
Code is not tested, just a demonstration. Valid for Vaadin 6, but I guess no significant changes comparing to Vaadin 7.
table = new Table();
// Wrap your beans collection into vaadin data container. There are many
// types of them , check Book of Vaadin.
BeanItemContainer<Bean> container = new BeanItemContainer<Bean>(Bean.class)
container.addBean(new Bean());
// Set collection of your beans as data source.
// Columns will be created for each property, vaadin uses reflection.
table.setContainerDataSource( container );
// You can select to display only properties you want, not all.
// Order matters. You can get columns list from any source - for example
// store in your DB.
table.setVisibleColumns( new Object[] {"prop1", "prop2"} );
// You can set column headers (by default vaadin will set them same as bean
// properties names). Order matters, should match above order.
table.setColumnHeaders( new String[] {"Property 1", "Property2"} );
The answer by Sergey Makarov is correct. This answer provides further information.
User’s Reordering
You may allow the user to drag-and-drop columns in a table to re-order them at runtime. To enable this feature, call isColumnReorderingAllowed.
You can use a listener to be informed when such a reorder event occurs.
The user’s re-ordering lasts only for this work session. If you want to maintain the user’s order in future work sessions, you must somehow persist their desired order and apply the order when instantiating the table again.
Losing The Order
If you replace the data source of the table, your column order will be reset. You can get the current order before the change, then restore. Example code follows.
// Visible status & ordering.
java.lang.Object[] visibleColumns = this.exampleTable.getVisibleColumns();
// ------| Fresh Data |--------------
// Put fresh data into the Table.
this.exampleTable.setContainerDataSource( freshBeanItemContainer );
// ------| Restore Config |--------------
// Visible status & ordering.
this.exampleTable.setVisibleColumns( visibleColumns ); // Assumes the table has the same properties.
By the way, as with visibility and order, being collapsed will also be reset with fresh data. You may want to track and restore column collapsing as well as ordering.
I am trying to localize selectOptions on the Visual Force page.
Here is the .class code snippet:
List<SelectOption> options = new List<SelectOption>();
List<MyOption__c> dropDownValues = [SELECT Id, Display_Label_Name__c FROM MyOption__c];
for (MyOption__c val : dropDownValues) {
// Display_Label_Name__c field is the label from *.labels that needs to be translated
options.add(new SelectOption(val.Id, val.Display_Label_Name__c));
}
Here is the .page code snippet:
<apex:selectList value="{!myVal}">
<apex:selectOptions value="{!options}"/>
</apex:selectList>
Right now the dropdown displays the Display_Label_Name__c verbose. I am trying to see how I can display the translated version from the .labels file. Is it possible? If not, what's the work around?
Thank you for your responses!
All localisation of page text can be done with Custom Labels.
Enable the translation workbench with the languages you require.
Create labels for all the localisible text on the page.
Replace the page text with the labels.
Add a translation for each label.
Change your profile langauge to test.
But for your case you pull the select option text from a custom object. If the values of the select list are not expected to change frequently, less than once a week or so, then I would change to using custom labels.
Otherwise, you lose the value of Salesforce automatic language selection and have to implement something yourself.
I would recommend extending the custom object MyOption__c to have columns for all the supported languages. You could use an if/else block or dynamic apex to select the select option text.
Sample using Dynamic Apex
string language = ParseForSupportedLangauges(UserInfo.getLanguage()); // includes __c
list<sobject> dropDownValues = Database.query('SELECT Id, '+language+' FROM MyOption__c');
for (sobject val : dropDownValues) {
options.add(new SelectOption(val.get('Id'), val.get(language)));
}
ParseForSupportedLangauges() would be a custom method that checks for supported languages and assigns the default when necessary.
EDIT
Turns out there is a solution: Don't look for something until you need it, right?
Introduced in Spring '12 is the ability dynamicaly select the label to display suing array syntax. Also, the ability to create visualforce components from the controller was added but using the array syntax would be sufficient for your problem. This method would allow you to select the labels you want by using the query results from MyOption__c.
Using a repeat in visualforce to loop over the query results
<apex:repeat value="{!displayResultsValues}" var="labelName">
<apex:outputText value="{!$Label[labelName]}"/>
</apex:repeat>
Here is a good article to show the usage and syntax.
I've just updated my project from jquerymobile 1.0a1 to version 1.0.
I've encountered a problem with dynamic content. Based on an ajax search I populate an unordered list with list items. Previous the following code refreshed the list so that all the styling appeared correctly:
$('#myContent').find("ul").listview();
$('#myContent').find("ul").listview('refresh');
However as of 1.0 this no longer seems to work.
The list appears but the styling is all wrong and the data-theme on all the elements gets ignored.
Has anyone come across a similar issue with updating and come across the solution.
Updating lists If you add items to a listview, you'll need to call the refresh() method on it to update the styles and create
any nested lists that are added. For example:
$('#mylist').listview('refresh');
Note that the refresh() method only affects new nodes appended to a
list. This is done for performance reasons. Any list items already
enhanced will be ignored by the refresh process. This means that if
you change the contents or attributes on an already enhanced list
item, these won't be reflected. If you want a list item to be updated,
replace it with fresh markup before calling refresh.
http://jquerymobile.com/demos/1.0/docs/lists/docs-lists.html
if #myContent is the listview you can do this:
$('#myContent').listview('refresh');
if #myContent is the page you can do something like this:
$('#myContent').trigger('create');
Create vs. refresh: An important distinction Note that there is an important difference between the create event and refresh method
that some widgets have. The create event is suited for enhancing raw
markup that contains one or more widgets. The refresh method should be
used on existing (already enhanced) widgets that have been manipulated
programmatically and need the UI be updated to match.
For example, if you had a page where you dynamically appended a new
unordered list with data-role=listview attribute after page creation,
triggering create on a parent element of that list would transform it
into a listview styled widget. If more list items were then
programmatically added, calling the listview’s refresh method would
update just those new list items to the enhanced state and leave the
existing list items untouched.
http://jquerymobile.com/demos/1.0/docs/pages/page-scripting.html
What you want can be achieved by replacing your 2 lines of code with the following:
$('#myContent ul').listview('create');
Hope this helps...
I've had this issue. The reason you are getting things all messed up is you are initalizing and refreshing the element multiple times. I noticed I had 2 different functions running that would call .listview('refresh') on the same element. After I took one out the themes and data went back to looking normal. Also are you getting any JS errors?
EDIT:
To be more specific you are calling .listview() somewhere in your code 2 times which is initializing it twice. I would wait to before you page is loaded to run the refresh so you only call it once.
Another thing you could do is check if the element is initialized already or not so you don't do it twice. Just check the element or in some cases the parent to see if the class ui-listview is present.
var element = $('#myContent').find('ul');
if ($(element).hasClass('ui-listview')) {
//Element is already initialized
$(element).listview('refresh');
} else {
//Element has not been initiliazed
$(element).listview().listview('refresh');
}
Just an FYI you can chain those events to look like $('#myContent').find('ul').listview().listview('refresh');
It cand be achived through.
$('#myContent').listview('refresh');
The below snippet shows you to load data from xml and dynamically create a list view.
function loadData()
{
$.ajax({
url:"BirthdayInvitations.xml",
dataType: "xml",
success: function(xml)
{
$(xml).find("event").each(function()
{
$("#mymenu").append('<li>' + this.textContent + ' </li>');
});
$("#mymenu").listview('refresh');
}
});
}
See if this is related to ur question http://www.amitpatil.me/demos/jquery-mobile-twitter-app/ and this one also http://www.amitpatil.me/demos/ipad-online-dictionary-app/
In first example i am using listview('refresh'); method and in second example i am using
$(document).page("destroy").page();
I have two tables with different structure:
TableSource:
intId(not null), txtSummary, strDetail
TableDesc:
guidId(not null), guidFK(not null), Name, Detail
I want to migrate data from two fields of tableSource(txtSummary, strDetail) to
two fields of tableDesc(Name, Detail).
guidId is auto generation and guidFK should be assigned to a fixed value.
I'v tried writing some t-sql code lines but not success. Could anyone help me?
Something like:
INSERT into TableDesc (Name, Detail)
SELECT txtSummary, strDetail
FROM TableSource
should work, if the other fields are auto-generated on insert like you said.
Which database is this using?
