Hi All,
I have a form where i have a field - netValue and this field follows by a sap.m.table with mode : multiselect.
In the table we have one column - totalPrice , Now on selection of any row the net Value should be calculated like : new netValue = previous net value - selected rows total price.
And if user deselect the row, then it should become netValue = previous net value + selected rows total price.
The user should also have the option of selecting all rows and deselecting all rows.
any pointers will be helpful.
Thanks

Hi Vishal,
i have tried with your scenario, the following code snip may help you
view1.view.xml
<HBox><Label text="Net Value:" class="sapUiTinyMargin"/><Input value="{viewData>/netValue}" /></HBox>
<Table id="productsTable" items="{data>/ProductCollection}" mode="MultiSelect" selectionChange="onSelect">
<columns>
<Column id="productCol" width="12em"><Text text="Product"/></Column>
<Column id="supplierCol" minScreenWidth="Tablet" demandPopin="true"><Text text="Supplier"/></Column>
<Column id="priceCol" hAlign="End"><Text text="Price"/></Column>
<Column id="netPrice" hAlign="End" mergeDuplicates="true"><Text text="Net Price"/></Column>
</columns>
<items>
<ColumnListItem>
<cells>
<ObjectIdentifier title="{data>Name}" text="{ProductId}" class="sapMTableContentMargin"/>
<Text text="{data>SupplierName}"/>
<ObjectNumber number="{data>Price}"/>
<Text text="{viewData>/netValue}"/>
</cells>
</ColumnListItem>
</items>
</Table>
view1.controller.js
onInit: function() {
var oJsonModel = new JSONModel({
"ProductCollection": [{
"ProductId": "HT-1000",
"Name": "Notebook Basic 15",
"SupplierName": "Very Best Screens",
"Price": 956
}, {
"ProductId": "HT-1001",
"SupplierName": "Very Best Screens",
"Name": "Notebook Basic 17",
"Price": 1249
}, {
"ProductId": "HT-1002",
"SupplierName": "Very Best Screens",
"Name": "Notebook Basic 18",
"Price": 1570
}, {
"ProductId": "HT-1003",
"SupplierName": "Smartcards",
"Name": "Notebook Basic 19",
"Price": 1650
}, {
"ProductId": "HT-1007",
"SupplierName": "Technocom",
"Name": "ITelO Vault",
"Price": 299
}]
});
this.getView().setModel(oJsonModel, "data");
this.iNetValue = 1000;
var oViewModel = new JSONModel({
"netValue": this.iNetValue
});
this.getView().setModel(oViewModel, "viewData");
},
onSelect: function(oEvent) {
var oView = this.getView(),
oJsonModel = oView.getModel("data"),
aListItems = oEvent.getSource().getSelectedItems(),
iNetValue = this.iNetValue;
//loop through the selected items
aListItems.forEach(function(listItem, index) {
var sPath = listItem.getBindingContextPath();
iNetValue += oJsonModel.getProperty(sPath).Price;
});
oView.getModel("viewData").setProperty("/netValue", iNetValue);
}

Hi Vedaradhya,
Thanks , this logic work after small change :)

Hi,
use mode="MultiSelect" selectionChange="<your event name>".
selectRow : function(oEvt){
// Check if all selected
if(oEvt.getSource()._getSelectAllCheckbox().getSelected() == true){
// Loop on your model and add all fields
} else {
if(oEvt.getParameter("selected") == true){
//get rows binding context and total price then subtract from net price
} else {
//add to netprice
}
}
}
Hi Irfan,
Thanks, I am trying this with my code,
can you tell me from where I can get more information on the functions like :
._getSelectAllCheckbox()
Thanks

Hi,
I have found it in a debugger. I'm not sure please check API reference in SapUI5 Demokit
Hi Irfan,
It did not work in one of the case when the user deselect all the rows using the checkbox in header row.
it is working fine 1) when user select all rows 2) select /deselect single row . the sample code is like:
handleSelect: function(oEvent) {
var columnGrPrice = 0.00;
var gPrice = 0.00;
var newRemValue = 0.00;
var initialRemValue = parseFloat(this.getView().byId("idRemainingVal").getText());
// get the number of selected rows from table eg if 3 out of 5 rows are selected
var oTable = this.getView().byId("idItemTable");
var oLength = oTable.getSelectedItems().length;
// get the index of selected row , if only one row is selected / deselected
var selectedIndex = oEvent.getSource()._oItemNavigation.getFocusedIndex();
// Check if all selected
if (oEvent.getSource()._getSelectAllCheckbox().getSelected() == true) {
// Loop on your model and add all fields
for (var s = 0; s < oLength; s++) {
columnGrPrice = columnGrPrice + parseFloat(oTable.getItems()[s].getCells()[4].getValue());
}
newRemValue = initialRemValue - columnGrPrice;
}else{
if (oEvent.getParameter("selected") == true) {
//get rows binding context and total price then subtract from net price
gPrice = parseFloat(oTable.getItems()[(selectedIndex - 1)].getCells()[4].getValue());
newRemValue = initialRemValue - gPrice;
} else {
//add to netprice
gPrice = parseFloat(oTable.getItems()[(selectedIndex - 1)].getCells()[4].getValue());
newRemValue = initialRemValue + gPrice;
}
}
this.getView().byId("idRemainingVal").setText(newRemValue);
},
Thanks
