Data Binding from TableSelectDialog to Form - sapui5

I'm using TableSelectDialog to view some Carrier details. All I need is: If I select any item (row), then all the values from that row should get automatically populated to the form input fields.
In the attached image, if Carrier Name is selected from TableSelectDialog, then the remaining fields should be populated based on that value.

You can achieve the required functionality using the Binding context that you receive from the TableSelcect Dialog.
But for binding context to work properly, both form and the table select dialog should refer to the same Model.
Below is the working code:
VIEW.XML:
Has a Button to trigger the table select dialog.
Has a form.
<l:VerticalLayout class="sapUiContentPadding" width="100%">
<l:content>
<Button class="sapUiSmallMarginBottom" text="Show Table Select Dialog"
press="handleTableSelectDialogPress">
</Button>
<VBox class="sapUiSmallMargin">
<f:SimpleForm id="SimpleFormDisplay354">
<f:content>
<Label text="Supplier Name" />
<Text id="nameText" text="{SupplierName}" />
<Label text="Description" />
<Text text="{Description}" />
<Label text="ProductId" />
<Text text="{ProductId}" />
<Label text="Quantity" />
<Text id="countryText" text="{Quantity}" />
</f:content>
</f:SimpleForm>
</VBox>
</l:content>
</l:VerticalLayout>
Controller:
onInit: function () {
// set explored app's demo model on this sample
var oModel = new JSONModel(jQuery.sap.getModulePath("sap.ui.demo.mock", "/products.json"));
this.getView().setModel(oModel);
},
handleTableSelectDialogPress: function (oEvent) {
if (!this._oDialog) {
this._oDialog = sap.ui.xmlfragment("sap.m.sample.TableSelectDialog.Dialog", this);
}
this.getView().addDependent(this._oDialog);
// toggle compact style
this._oDialog.open();
},
handleClose: function (oEvent) {
var aContexts = oEvent.getParameter("selectedContexts");
if (aContexts && aContexts.length) {
// MessageToast.show("You have chosen " + aContexts.map(function(oContext) { return oContext.getObject().Name; }).join(", "));
this.byId('SimpleFormDisplay354').setBindingContext(aContexts[0]);
}
oEvent.getSource().getBinding("items").filter([]);
}
Now, we also have a Select dialog and on click of any Item we call method : handleClose
In handleClose, we obtain the clicked Item binding context and then tell the form : hey! refer to this context ( which is present in the model). Binding context has a path which tells the form from where to do the relative binding.
Please feel free to contact for more information.

SAP UI5 : Unable to bind a controller variable in xml

Button on click of which the variable is getting changed:
<f:content>
<Button icon="sap-icon://edit" press="editClick" type="Transparent"></Button>
</f:content>
xml code where i need 2-way binding:
<VBox class="sapUiSmallMargin">
<form:SimpleForm id="SimpleFormDisplayColumn_oneGroup">
<form:content>
<Label text="{i18n>contextofusage}"/>
<Text text="{contextofusagetext}" visible="{!isInfoEditable}"/>
<Input type="Text" visible="{isInfoEditable}" value="{contextofusagetext}"></Input>
</form:content>
</form:SimpleForm>
</VBox>
controller:
var isInfoEditable=false;
return Controller.extend("abc.controller.Detail", {
editInfoClick: function(event){
if(isInfoEditable){
isInfoEditable=false;
}
else{
isInfoEditable=true;
}
}
});
It seems like you have tried nothing, but I will try to guide you:
You cannot simply declare a variable in your controller and then use it in your view. That's not how UI5 works. Instead create a model and bind it to your view. I also give my models a name, in this case "view":
onInit: function() {
var oViewModel = new sap.ui.model.json.JSONModel({
isInfoEditable: false
});
this.getView().setModel(oViewModel, "view");
}
Then use it in your view. Make sure that you use the name of your model ("view") in your bindings. If you want to do more than simply use the raw value (e.g. negate it) you have to use expression binding. Also you have to use an absolute path starting with /:
<form:SimpleForm id="SimpleFormDisplayColumn_oneGroup">
<form:content>
<Label text="{i18n>contextofusage}"/>
<Text text="{contextofusagetext}" visible="{= !${view>/isInfoEditable} }"/>
<Input type="Text" visible="{view>/isInfoEditable}" value="{contextofusagetext}"></Input>
</form:content>
</form:SimpleForm>
When you click on the button you have to modify/toggle the value in your model:
editClick: function (oEvent) {
var oViewModel = this.getView().getModel("view");
var bIsEditable = oViewModel.getProperty("/isInfoEditable");
// negate the current value and set it as the new value
oViewModel.setProperty("/isInfoEditable", !bIsEditable);
}
I suggest strongly reading on the basics of UI5. Your approach looks more like Vue.js, but UI5 has its own paradigms.

Add button in sap.m.list row

I want to add buttons to each row in my sap.m.List. On that button I want to open a popup to display further details without navigating to another page.
Any code snippet or examples out there how I can add buttons to each row and bind them to fetch data from another model.
Instead of the StandardListItem you need a CustomListItem. There you can add any control you like:
<List headerText="Custom Content" items="{path: '/ProductSet'}" >
<CustomListItem>
<HBox>
<Label text="{ProductName}"/>
<Button text="More Infos" click="onPressMoreInfos" />
</HBox>
</CustomListItem>
</List>
I think the tricky part here is the binding. One CustomListItem is bound to a single entity of your set. If you add a Button to your CustomListItem (or any other control) they are also automatically bound to the specific entity.
So in your click handler you can do the following:
onPressMoreInfos: function(oEvent) {
var oButton = oEvent.getSource();
// if your model has a name, don't forget to pass it as a parameter
var oContext = oButton.getBindingContext();
// create the popover, either here or in a new method
var oPopover = this.getTheInfoPopover();
// if your model has a name, don't forget to pass it as the second parameter
oPopover.setBindingContext(oContext);
}
Then your Popover has the same binding information as the list item and you can access every property of the specific entity.
Try below code to add a button to each row, in your XML view:
<columns>
<Column id="userNameColumn">
<Text text="userNameLabelText" />
</Column>
<Column id="buttonColumn">
<Text text="Button" />
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<Input value="{UserName}"/>
</cells>
<Button id="buttonId" icon="sap-icon://add" press="handleResponsivePopoverPress"></Button>
</ColumnListItem>
</items>
Controller to handle button press, see example here
https://sapui5.hana.ondemand.com/#/sample/sap.m.sample.ResponsivePopover/preview
You can use sap.m.CustomListItem as a template for items aggregation. There is a sample here. You can add any control to the item.

How can I bind a single property of my OData service to a Form?

Will you please tell me how to refer to the first tabular (and single) record?
There is a table with only one record:
<Table items="{WaybillsPlaces}" mode="SingleSelectMaster">
<columns>
<Column hAlign="Center">
<header>
<Text text="Number" />
</header>
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<Text text="{CoNumber}" />
</cells>
</ColumnListItem>
</items>
</Table>
How can I read the field of the first record without a table?
<Text text="{WaybillsPlaces[0]/>CoNumber}"/>
I get a table reply, but I do not want to display it in the table - I want to display it in the form in text boxes, so there will always be one line in the response.
<entry>
<id>
http://xxxxx.xxx.local:8000/sap/opu/odata/sap/LOGISTICS_SRV/WaybillsPlaces('4610103052')

I have an OData giving me the following entry

<d:CoNumber>46101030520001</d:CoNumber>
</m:properties>
</content>
</entry>
How can I bind the CoNumber property with a Input within a From ??
give and ID to your table, get the table in your controller and call its 'getItems()' method. Then get the first object in the returned array:
In your view
<Table id="myTable" items="{WaybillsPlaces}" mode="SingleSelectMaster">
<columns>
<Column hAlign="Center">
<header>
<Text text="Number" />
</header>
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<Text text="{CoNumber}" />
</cells>
</ColumnListItem>
</items>
</Table>
In your controller
onCertainEvent(evt){
var oTable = this.getView().byId('myTable');
var oFirstItem = oTable.getItems()[0]; // This is your ColumnListItem object in the first row
var oFirstCellItem = oFirstItem.getCells()[0]; // This is your Text object in the first cell of the first row
var sCellText = oFirstCellItem.getText(); // This is the text string in your first cell of the first row
}
EDIT: bind only the first item in your model
In this case you can do aggregation binding. For aggregation binding you need multiplicity greater than 1. So do property binding in yout ColumnListItem with WaybillsPlaces/0/CoNumber
<Table id="myTable" mode="SingleSelectMaster">
<columns>
<Column hAlign="Center">
<header>
<Text text="Number" />
</header>
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<Text text="{WaybillsPlaces/0/CoNumber}" />
</cells>
</ColumnListItem>
</items>
</Table>

EDIT2: Bind a form input to a certain property in a OData Model
Here I'm gonna use Northwind OData service, for ease of use, but you just need to use your own model. I used the "Customers" entitySet (a.k.a "Customers" DB table), and the "CustomerName" property in this entitySet.
In your case (as per the given OData in the description, you should use the 'WaybillsPlaces' entity and your 'CoNumber' property. If you want to access one specific entry, provide the Key between parenthesis in the binding URL (in your case: WaybillsPlaces('4610103052')).
I highly recommend you to read more about OData binding in UI5 (here and here). In a productive application, please set your OData model in the manifest.json file, to be sure that the $metadata call is done when the application starts, avoiding this way performance and many other issues.
HERE THE SNIPPET

oData binding to Simple Form

I'm creating a read only form that will be used to display a summary of information. I need to send a parameter to the backend first before getting the information but I don't seem to see that parameter is reaching it.
It does reach the entity set but it does not show the parameter. Am I binding correctly?
This is on the controller:
onInit: function() {
var urlEnding = "1000012233";
var oFilterDist = new sap.ui.model.Filter("ID",
sap.ui.model.FilterOperator.EQ, urlEnding);
var summaryText = this.getView().byId("summaryForm");
summaryText.bindElement({
path: "/SummaryScreenSet",
filters: [oFilterDist]
});
}
This is on the View
<VBox class="sapUiSmallMargin" fitContainer="true"
height="100%" width="100%" justifyContent="End"
displayInline="true" id="leftVBox" items="{/SummaryScreenSet}">
<items>
<f:SimpleForm editable="true" layout="ResponsiveGridLayout" id="summaryForm" columnsL="1" columnsXL="1" labelSpanL="5" title="Account Summary" labelSpanM="5">
<f:content>
<Label text="Status" id="__label6" design="Bold" class="sizeText"/>
<ObjectStatus text="{CONTRACT_STATUS}" id="__status6" state="Success" class="boldText"/>
<Label text="Permit Required" id="__label10" design="Bold" class="sizeText"/>
<Text text="{PERMIT_REQD}" id="__text32" wrapping="false" class="sizeText"/>
<Label text="Bill Date | Due Date" id="__label11" design="Bold" class="sizeText"/>
<Text text="{BILL_DATE} | {DUE_DATE}" id="__text33" wrapping="false" class="sizeText"/>
<Label text="Last Estimated Date | Next MR Date" id="__label17" design="Bold" class="sizeText"/>
<Text text="{LAST_PAYMENT_DATE} | {nextMRDate}" id="__text39" wrapping="false" class="sizeText"/>
</f:content>
</f:SimpleForm>
</items>
</VBox>
Going to assume you want a single, specific entry. In that case, what you're looking for is the Entity, not the EntitySet + filter. Coincidentally, here's one I wrote yesterday that works. I've changed the paths and ID's to reflect yours:
var form = this.getView().byId('summaryForm');
form.bindElement({
path: "/SummaryScreenSet('" + urlEnding + "')",
events: {
change: function() {
//triggers on error too I think
form.setBusy(false);
},
dataRequested: function() {
form.setBusy(true);
}
}
});
In that case you don't need the VBOX either, just the form. Don't forget to implement SUMMARYSCREEN_GET_ENTITY or whatever the method is on your DPC_EXT.
Edit: might want to set editable on the form to false, it shrinks the layout to suit text instead of inputs.

Get bound values from pressed List Item in UI5 controller

I'm a beginner to SAP Fiori (UI5) and trying to retrieve a value from a table made with sap.m.Table in SAP Web IDE. But I don't succeed. Anybody hints on how to get there?
<Table id="table0" items="{/Entity1_Set}">
<ColumnListItem detailPress=".onShowHello" type="DetailAndActive">
<Text id="text5" maxLines="0" text="{Id}" />
<Text id="text6" maxLines="0" text="{field1}" />
<Text id="text7" maxLines="0" text="{field2}" />
<Text id="text8" maxLines="0" text="Euro"/>
</ColumnListItem>
<columns>
<Column id="column0">
<Label id="label0" text="Floor"/>
</Column>
</columns>
</Table>
sap.ui.define([
"sap/ui/core/mvc/Controller",
"sap/m/MessageToast",
], function(Controller, MessageToast) {
"use strict";
return Controller.extend("QuickStartApplication.controller.View1", {
onShowHello: function(){
MessageToast.show("Hello World!");
},
});
});
In the "hello world"-MessageToast, I would like to display values of the fields in my table.
You can pass parameters in the function, which is called during an event.
Please see also https://sapui5.hana.ondemand.com/#docs/api/symbols/sap.m.ListItemBase.html#event:detailPress
Using these parameters, you can access the bound data.
Please see the following code on how to read the binding context of the ColumnListItem:
detailPress : function(oEventParams){
var oListItem = oEventParams.getSource();
var oBindingContext = oListItem.getBindingContext(); var sSomePropertyValue = oBindingContext.getProperty("<nameOfProperty>"); }
Using .getProperty, you can access your field values.
