Can I use setFilteringMode of ComboBox in ListSelect ? I didn't found anyway to do this. I am so supprised due to this mothod didn't support in ListSelect. I don't think ComboBox and ListSelect are too many differences. So , if I want to use Filtering in ListSelect , how can I figure it out ?
As a possible solution, you can create a textfield below your ListSelect and use a filterable container (https://vaadin.com/api/com/vaadin/data/Container.Filterable.html) as the data source of your ListSelect and apply a container filter e.g. on each "return" in this textfield or even on each text-change event.
IndexedContainer c = new IndexedContainer();
listSelect.setContainerDataSource(c);
Filter filter = new SimpleStringFilter("name", "Douglas", true, false);
c.addContainerFilter(filter);
See the Book of Vaadin - Filterable Containers

I was wondering if you guys can help me with something.
i have the following code set:
$(document).on('mouseenter','input',function(){
soundHover.play();
});
$(document).on('mouseleave','input',function(){
soundHover.pause();
soundHover.currentTime = 0;
});
I also have a Jquery UI controlGroup formed from different controls.
I would want to use 1 function for all different controls something like instead of 'input' use 'input label select'. I works for each separately, but when i use them together, it does not work.
Is it possible to refer to multiple controls in a control group? if yes, how can I do it?
Regards,
I was using the wrong delimiter, if i use "," between the control it works as intended.
$(document).on('mouseenter','input,label,a',function(){
soundHover.play();
});
$(document).on('mouseleave','input,label,a',function(){
soundHover.pause();
soundHover.currentTime = 0;
});
I still have not gotten the 'select' part to work though.
I know if i have a select2 and i want to set one of the options, i can do run this code.
$(document).ready(function(){
$('#btn').change(function(){
$('#select').val(4).trigger("change")
});
});
Lets say i want to get the text of the option
<option value=4>California</option>
but if i want to set it based on the text not the value, how do i do it?
I tried doing
$("#select").select2(data.text(), "California");
but it didnt work.
How can i do this programatically in jquery or javascript.
Any help is appreciated
For example: If you need to find Australia among other countries
let long_name = 'Australia';
let $element = $('.country-js')
let val = $element.find("option:contains('"+long_name+"')").val()
$element.val(val).trigger('change.select2');
Other answers did not work for me, probably because I use newer version of select2
In addition for multi selects use this, for not losing already selected values
var selected=$("#foo option:selected").map(function(){ return this.value }).get();
selected.push( $("#foo option:contains('text')").val() );
$("#foo").val(selected).trigger('change');
Further to Shakeel Ahmed's answer, you should call .trigger('change'), so in total something like this:
$("#select").select2("val", $("#select option:contains('Text')").val()).trigger('change');
You can use following codes
$("#select").select2("val", $("#select option:contains('Text')").val() );
If will select option using your Text
In the Grid widget in Vaadin 7.5.3, we can determine the current selection of rows by calling SelectionEvent::getSelected or Grid::getSelectedRows.
So how do we set the selection programmatically?
While that's true that official documentation for Grid class doesn't have this method stated, still you can do it programmatically. I won't argue whether it's a bug or not. Firstly you need to know what is your SelectionMode. Then you can select a row (or rows):
#Override
protected void init(VaadinRequest request) {
final VerticalLayout layout = new VerticalLayout();
Customer c = new Customer(1);
container = new BeanItemContainer<>(Customer.class, Arrays.asList(c, new Customer(2)));
grid = new Grid(container);
grid.setSelectionMode(SelectionMode.SINGLE);
SingleSelectionModel m = (SingleSelectionModel) grid.getSelectionModel();
m.select(c);
layout.addComponents(grid);
setContent(layout);
}
In newer Vaadin (in my case 7.5.6) there is select(Object) method directly in Grid interface.
Example:
Grid grid = new Grid(container);
grid.setSelectionMode(Grid.SelectionMode.SINGLE);
grid.select(row);
The row object for example could be taken from SelectionListener event or from added before object (as in #kukis answer).
Setter Method Missing (bug?)
The Book of Vaadin mentions the setter method Grid::setSelectedRows along with a getter.
The currently selected rows can be set with setSelectedRows() by a collection of item IDs, and read with getSelectedRows().
However, the Grid class doc does not list that method. Nor does NetBeans 8.0.2 suggest that method in its auto-complete.
So apparently a bug. See Ticket # 18,580.
1. Binding Lists
I wonder how I could bind a ObservableCollection to a Radiogroup:
new Section(){
new RootElement("Mandanten", new RadioGroup("mandanten", 2)) {
new Section(){
new RadioElement("Kupus", "mandanten"),
new RadioElement("Kajmak", "mandanten")
}
}
}
as you see here I'm creating 2 Items/Elements manually but I miss something like an "ItemsSource".
If its not possible, what recommendation would you give me? To use witch Control (to bind Lists)?
2. CommandBinding
As I see theres no "button" in MonoTouch.Dialog. So I saw that we'll use "StringElement".
I tried it, but after tapping on the "button" nothing happened:
new StringElement("Login").Bind(this, "SelectedCommand LoginCommand")
I'm not sure whats wrong, maybe I need to use here the new "variant", like that:
new EntryElement ("User", "Loginuser", ViewModel.User).Bind(target, v => v.Value, t => t.User),
But I'm not sure how to build that similiar code to bind a command for a particular "stringelement" (in that case - a button with the ontap event)..
Any help appreciated!
1. Binding lists
An example of binding dynamic ObservableCollection lists is in https://github.com/slodge/MvvmCross-Tutorials/blob/master/DialogExamples/DialogExamples.Touch/Views/ThirdView.cs - it uses some custom elements from https://github.com/slodge/MvvmCross-Tutorials/tree/master/DialogExamples/DialogExamples.Touch/BindableElements - which was based on the sample from https://github.com/asednev/MvvmCross.AlexeysExtensions
Because of the way Radio lists are internally implemented, I don't know if the same ObservableCollection binding approach would work for radio lists - someone would need to prototype and experiment to work this out. However, a simple fixed radio list is shown in https://github.com/slodge/MvvmCross-Tutorials/blob/master/DialogExamples/DialogExamples.Touch/Views/FirstView.cs
2. CommandBinding
See an example in: https://github.com/slodge/MvvmCross-Tutorials/blob/master/DialogExamples/DialogExamples.Touch/Views/FirstView.cs
new Section("Action")
{
new StringElement("Second").Bind(bindings, element => element.SelectedCommand, vm => vm.GoSecondCommand),
new StringElement("Bindable Elements").Bind(bindings, element => element.SelectedCommand, vm => vm.BindableElementsCommand)
},
I want to create Vaadin drop down with 2 separators in it. I couldn't find a way to implement that, can anyone help me to solve this issue?
This is the way I want to display my drop down:
Option 1
Option 2
------------;
select 1
select 2
-----------;
group 1
How can I do that?
There is no built-in way to add separators to selects. The only way I can think of is to add an item with the desired separator as its caption. For example if you use the default caption (item id) select.addItem("-----"); should be enough. This should work for both ComboBoxes and NativeSelects.
You can implement a new Vaadin component including the client behaviour, but this is not an easy solution. This page https://vaadin.com/book/-/page/gwt.html of "Book of Vaadin" and Vaadin forum can help for that.
Also, creating your own component using existing components is another solution. You can implement a special combobox which takes values of String or Component arrays. The way of doing this is using Vaadin panels, layouts and windows with size and locations and click listeners.
I haven't tried it myself but give a go at NativeSelection dropdown.
You can always do
{select.addItem("-----");}
Once I also wanted a do something like that but there was no proper way to do that with Vaadin. I actually created a Vaadin widget extending the Combo Box. In the client side widget of Vaadin they filter out the HTML content before adding items to the list. So Using the client side code I override that functionality and use HTML tag "" to add the line.
select.addItem("-----");
looks like the best way, I dont know about some other
Btw if you are reading items from some list you can combine that with some item counter and (itemsCount%n)==0 operator to set separator after 'n' items inserted :)
You can add the item to the selected (as mentioned before) and then disable the separators with some javascript:
add the item to the select.
cb.addItem("separator");
cb.setItemCaption("separator", "-------------");
execute the javascript
final String javascript = ""
"var selects = document.getElementsByTagName('select');"
"for(var j = 0;j < selects.length;j++){"
"var op = selects[j].getElementsByTagName('option');"
"for (var i = 0; i < op.length; i++) {"
" if(op[i].text == '" + separatorText + "') op[i].disabled = true;"
"}}";
Page.getCurrent().getJavaScript().execute(javascript);
Is there a reason that you use the ComboBox instead of the Select, because with the select you can do that.
Select select = new Select();
select.setItems("Option 1", "Option 2", "select 1", "select 2", "group 1");
select.addComponentAtIndex(2, new Hr());
select.addComponentAtIndex(5, new Hr());
Or you can use a MenuBar but it looks very diferent that the ComboBox.
menuBar = new MenuBar();
MenuItem menuItem = menuBar.addItem("Select");
menuItem.getSubMenu().addItem("Option 1");
menuItem.getSubMenu().addItem("Option 2");
menuItem.getSubMenu().addItem(new Hr());
menuItem.getSubMenu().addItem("select 1");
menuItem.getSubMenu().addItem("select 1");
menuItem.getSubMenu().addItem(new Hr());
menuItem.getSubMenu().addItem("group 1");
