In one of my UI5-Dialogs, I implemented a combobox which is invisible when the screen is initially loaded.
In the method onAfterRendering, I start with setting the input to read-only:
onAfterRendering: function(oEvent) {
var oShovel = this.getView("View0200").byId("comboShovel");
oShovel.$().find("input").attr("readonly", true);
this.setVisibleByListKey();
},
After this the method setVisibleByListKey is called, the property visibleShovel will be set to false.
setVisibleByListKey: function(oEvent) {
var oModel = this.getView("View0200").getModel("Data0200");
this.setVisibleByListKey1(oModel);
// ...
},
setVisibleByListKey1: function(oModel) {
oModel.setProperty("/visibleShovel", false);
},
The property is bound to the attribute visible on my combobox.
Because of this behavior, the method onAfterRendering will be called again, the attribute readonly is not available (because of invisibility).
<ComboBox id="comboShovel"
editable="true"
enabled="true"
visible="{Data0200>/visibleShovel}"
valueState="None"
change=".changeCombo">
<items>
<core:Item text="Ja" enabled="true" key="0" />
<core:Item text="Nein" enabled="true" key="1" />
<core:Item text="Nicht erforderlich" enabled="true" key="2" />
</items>
</ComboBox>
I tried to call the set method in onInit or onBeforeRendering but at this time the input attributes can not be changed (because of invisibility again).
So how can I set the input of the combobox to read-only when I set the named visible property?
Solution would be either to use sap.m.Select or to implement a "change" event handler for the sap.m.Combobox and use a coding similar to this sample:
handleChange: function(oEvent) {
var oValidatedComboBox = oEvent.getSource();
var sSelectedKey = oValidatedComboBox.getSelectedKey();
var sValue = oValidatedComboBox.getValue();
if (!sSelectedKey && sValue) {
oValidatedComboBox.setValueState("Error");
oValidatedComboBox.setValueStateText("Please enter a valid country!");
} else {
oValidatedComboBox.setValueState("None");
}
},
Instead of using jquery, use UI5 control's methods and properties:
The sap.m.ComboBox borrows the following two methods from sap.m.InputBase:
setEditable
setEnabled
or since you are using property binding for the visibility, do the same for the editable property, e.g. {Data0200>/editableShovel}

I have an input box as you can see in the code below.
The data inside the input box is set using model#setProperty, but my onValueChange gets triggered only when I enter the value directly into the input box. It's not triggered when the value is manipulated via binding.
<!-- ... -->
<table:Column xmlns:table="sap.ui.table">
<Label xmlns="sap.m" text="{i18n>ItemCode}" required="true" />
<table:template>
<Input value="{model1>itemCd}" change=".onValueChange" />
</table:template>
</table:Column>
<!-- ... -->
onValueChange: function(oEvent){
console.log("inside function onValueChange");
},
Try with liveChange beacause from library doesn't exist event change, but event liveChange. Perhaps is deprecated?
As #Marc mentioned change event is part of the Input, not of the model. So it is only triggered if you change the actual Input and not the bound value. Its true but there is a workaround for it.
You can achieve it using input fireLiveChange event and formatter.
View.xml
<Input value="{path: 'ipModel>/text', formatter: 'assets.util.Formatter.triggerLiveChange'}"
liveChange="ipLiveChange" />
Controller.js
onInit: function() {
this.setInputModel();
},
setInputModel:function() {
var oModel = new sap.ui.model.json.JSONModel();
oModel.setData({ text: "Test Value"});
this.getView().setModel(oModel, "ipModel");
},
ipLiveChange: function(oEvent) {
console.log("LiveChange triggered!!");
}
Formatter.js
jQuery.sap.declare("assets.util.Formatter");
assets.util.Formatter = {
triggerLiveChange: function (value) {
this.fireLiveChange();
return (value);
}
};
I am using ColumnListItem to display a list of Sales Orders in Overview.view.xml. When the user clicks on an item of the list (of Sales Orders), the App should navigate to the Detail.view.xml.
I have defined the onPress event handler in Overview.Controller.js. But the App did not execute the function (I put an alert() there and it was not triggered). Why the onPress() is not triggered? How do I debug?
<Table items="{myOdata>/SalesOrderSet}">
<ColumnListItem type="Navigation" detailPress=".onPress">
<!-- ... -->
</ColumnListItem>
<columns>
<!-- ... -->
</columns>
</Table>
onPress: function (oEvent) {
//This code was generated by the layout editor.
alert("In");
var loOverview = "Data from Overview";
var oItem = oEvent.getSource();
var loRouter = sap.ui.core.UIComponent.getRouterFor(this);
loRouter.navTo("Detail", {
value: oItem.getBindingContext("oModel").getPath().substr(1)
});
},
The press function is not working as you have not written the correct handler for it. As per your code, the handler is written for detailPress. Just a typo, change the handler to press and it should just work.
Current:
<ColumnListItem type="Navigation" detailPress=".onPress">
Change required:
<ColumnListItem type="Navigation" press=".onPress">
the property that you should bind on the Table control is itemPress and your ColumnListItem need to have the type equals to Navigation
Can you check those?
ComboBox is not showing state like Error, Warning with highlight around the borders. But it does change the state. For example, if it is error state, and if I try to enter new value in combobox, it will show that "invalid Entry" tip near the box. But the box borders are never highlighted in red. Below is the code:
XML.view
<core:FragmentDefinition xmlns="sap.m" xmlns:core="sap.ui.core" xmlns:l="sap.ui.layout">
<Dialog id......>
<ComboBox id="combo1" change="cChanged" items="{path: '/results'}">
<items>
<core:Item key="{ID}" text="{Name}"/>
</items>
</ComboBox>
</Dialog>
Controller.js
cChanged: function(oEvent) {
var newval = oEvent.getParameter("newValue");
var key = oEvent.getSource().getSelectedItem();
if (newval !== "" && key === null) {
sap.ui.getCore().byId("combo1").setValueState("Error");
oEvent.getSource().setValue("");
sap.m.MessageToast.show("Please select from existing IDs")
flag = false;
} else {
oEvent.getSource().setValueState('None');
}
You can also access combo1 control instance by using oEvent.getSource() event OR use byId() from the sap.ui.core.Fragment class and not sap.ui.getCore().byId()
Also, if you are writing a logic only to validate if what the user input in the combobox is a valid item, consider replacing your ComboBox by the sap.m.Select control.
Both ComboBox and Select has same look and feel, but Select does not allow a manual input. It can also have an empty option if you use the property forceSelection
I'm building a master-detail app. I'm using sap.m.StandardListItem for listing master objects. I want that selected master object appear on a detail page.
<List id="lstRequest" headerText="Custom Content" selected="true" items="{
path: '/Requests',
parameters: {
expand: 'RequestTypeDetails'
}
}">
<StandardListItem
title="{RequestTypeDetails/RequestType2} - {RequestCode}"
description="{TotalAdvance}"
icon="sap-icon://request"
iconDensityAware="false"
iconInset="false"
type="Navigation"
press="onSelectApprovation"
/>
</List>
I'm following the guide from here but it doesn't work in my case.
var source = event.getSource();
var bindingobject = event.getBindingContext("Requests");
bindingobject is undefined.
Inside onSelectApprovation do the following:
var oItem = oEvent.getParameter("listItem") || oEvent.getSource());
var oCtx = oItem.getBindingContext();
var requestCode = oCtx.getProperty("RequestCode");
By the way: sap.m.List does not have a property called "selected" of type boolean. However, it has a select event that could also be used instead of using the press event of the StandardListItem...
Give the logical name while setting json model to list like below.
this.getView().byId("lstRequest").setModel(oListJson,"List");
oListJson will be your array of data.
now use your code for accessing list object in your onSelectApprovation fuction as below
onSelectApprovation : function(oEvent){
var bindingobject = oEvent.getSource().getBindingContext("List");
}
I have this fragment retrieve by this page https://openui5.hana.ondemand.com/explored.html#/sample/sap.m.sample.TableViewSettingsDialog/code
<core:FragmentDefinition
xmlns="sap.m"
xmlns:core="sap.ui.core">
<ViewSettingsDialog
confirm="handleConfirm" id='viewSettingsDialogId'>
<sortItems id="sortItemsId">
<!-- <ViewSettingsItem text="Product" key="Name" selected="true" />
<ViewSettingsItem text="Supplier" key="SupplierName" />
<ViewSettingsItem text="Weight" key="WeightMeasure" />
<ViewSettingsItem text="Price" key="Price" /> -->
</sortItems>
</ViewSettingsDialog>
</core:FragmentDefinition>
I want insert manually the sortItems in the control (or by data-binding in the xml-View).
How can I do it?
I try to do it by code in my controller:
//IF CLICK ON SETTINGS BUTTON
handleViewSettingsDialogButtonPressed: function (oEvent) {
if (!this._oDialog) {
this._oDialog = sap.ui.xmlfragment("apps.appIntra.fragment.settingDialog", this);
}
// toggle compact style
jQuery.sap.syncStyleClass("sapUiSizeCompact", this.getView(), this._oDialog);
this._oDialog.open();
var element=sap.ui.getCore().byId("sortItemsId");
this.byId('sortItemsId').addSortItem(new sap.m.ViewSettingsItem({text:"field1", key:"Price"}));
this.byId('sortItemsId').addSortItem(new sap.m.ViewSettingsItem({text:"field2", key:"PLUTO"}));
},
But it not work...
I see this guide http://scn.sap.com/community/developer-center/front-end/blog/2014/02/20/sapui5-dialogwith-businesscard-as-xml-fragment-along-with-controller
but if I use
var element=sap.ui.getCore().byId("sortItemsId");
element value is undefined
The addSortItem is a method that works on the ViewSettingsDialog and not on sortItems.
Therefore, as you have already provided the id viewSettingsDialogId for the ViewSettingsDialog control, in you controller you can do the following,
var oViewSettingsDialog = sap.ui.getCore().byId("viewSettingsDialogId");
oViewSettingsDialog.addSortItem(new sap.m.ViewSettingsItem({text:"field1",
key:"Price"}));
/* and so on... */
This would add the sort items into the sortItems list.
