I am trying to find out a solution to implement save functionality after the values in the ag-grid is changed.
I have an angular2 ag-grid with almost 100 columns but only 4 columns are editable. And on click of a save button on my web page i want to post only the changed values if any by the user, to the database. Is there any event which i can use to identify changed rows in the grid? Or any other suggestion to implement such scenario?
I looked at rowValueChanged and cellValueChanged event, but these event will trigger after every change? I need to get the values only after the user hits save button.
I have some data input fields inside a sap.m.table. Wanted to use Tab key to navigate to the input fields but it doesn't work.
It seems the SAP application interface hasn't implemented this feature.
I tried with some custom function and not working.
Any solution or alternative for this feature?
SAP itself now come up with the solution. Navigation with the TAB key is available form SAPUI5 version 1.44.
SAP NOTE 2387996 - SAPUI5 unable to use Tab to move to next field.
We have to press F2 key to activate this.
It's no longer necessary to use a custom solution for this. As of SAPUI5 version 1.38.0 sap.m.table has a property called 'keyboardMode' that can be set to 'Edit' which will change the tab behaviour to navigate focus through all editable fields in the table.
This mode is suitable if the number of items is limited and if there
are editable fields within the item.
While the last/first interactive element within an item has the focus,
pressing tab/shift+tab moves the focus to the next/previous element in
the tab chain after/before the item .

Attach browser event
new sap.m.Input({
value:"{first}"
}).attachBrowserEvent("keydown",function(oEvent){
if(oEvent.key == 'Tab'){
alert(this);//this reference to input control
//Your logic here
}
})

I have a spring mvc form with a drop down and radio button.
I want to redisplay the form for confirmation and the drop down and radio buttons are not retaining the selections in the command object.
The drop down displays all the contents from the list but doesnt show the selected option from the command as 1st option.
Appreciate your help.
use the spring forms tags and set the path attribute to the name of the variable in which you are storing the radio and drop-down selections.
Make sure that you are using form:radiobutton and not form:input type="radio".
I am trying to develop a quiz application using LWUIT resource editor and am having great difficulty.
I have created two Forms 'GUI1' and 'GUI2' .
GUI1 displays the following:
A question(in the form of a TextField)
5 RadioButtons belonging to the same group
A Button which says 'OK'
GUI2 displays the following:
A TextField
A Button to go back to GUI1
Now the problem is:
Initially GUI1 is displayed. When the user chooses a RadioButton , I wish to know which RadioButton was selected. If that RadioButton was indeed the correct answer, then when the user clicks on the 'OK' Button on GUI1, I wish to display the text 'correct' in the TextField on GUI2 and then display the GUI2.
If the user chose the wrong answer, then I wish to display the text "Wrong" in the TextField on GUI2 and then display the GUI2.
How can this be done with resource editor? I am very foxed. Please help.
I wish to refer to the TextField on GUI2 when I am currently on GUI1. How can this be done with resource editor? Writing a manual code for all this would be very time consuming.
Ok I will try to explain the best I can.
When you design the first Form GUI1 the five RadioButtons must be in the same group. I don't know how to do that in the resource editor (I think there is a field called ButtonGroup in the RadioButton, but I can't remeber). What I would do is take the five RadioButton by code in the before method of GUI1 and add them to a ButtonGroup element.
With ButtonGroup you can know which element is selected using ButtonGroup.setSelectedIndex(). When you press the Button take this value and act as appropriate to the situation.
If you don't understand anything please tell me and I will try to help you.
Is not a hard thing to do. There must be a way to do it with the Resoruce editor but at the moment I don´t know how.
As Shai mentioned, the best thing to do is to use listeners to set the "state" of the buttons on clicking them and when you move to the next form you just retrieve the state of the previous text field.
Manual code may actually be faster for you, do most of the UI in the resource editor and transfer to a form that is written manually. That way you have full control over your objects and transfer back into the GUI builder form when needed.
I have an application, that uses the MultiSelectionModel, and it works great, but I need the site I'm developing to work on mobile devices, and so I can't use the keyboard to assist in selecting the elements (since it doesn't exist). EX: On the desktop I just hold ctrl and click on all the element that I want to select.
So on the mobile device, I would like to modify the default behavior of the MultiSelectionModel so that when you click on a CellList item, it toggles the selection state of that item.
I have looked through the source for it and cannot see anyway to implement the behavior that I need. (Mobile MultiSelection).
Whether you add a checkbox column or not, you'll have to add a cell preview handler. The easiest way to define one is to use DefaultSelectionEventManager, either using a checkbox manager in combination with a checkbox column, or creating a custom one (you'd map a click event into a toggle action).
You can see it used, the checkbox variant, in the GWT Showcase; it uses the setSelectionModel overload with two arguments to add the CellPreviewEvent.Handler at the same time.
Just adding an extra checkbox column would be a more user friendly solution.
