Hi,
When I am using DataSource for loading XML, the listview shows the data only if there is atleast 2 item in the XML.
import bb.cascades 1.0
import bb.data 1.0
NavigationPane {
id: nav
Page {
id: emp
titleBar: TitleBar {
visibility: ChromeVisibility.Visible
}
onCreationCompleted:
{
dataSource1.load(); //load the xml when page is created
}
actions: [
ActionItem {
title: qsTr("Create List")
ActionBar.placement: ActionBarPlacement.OnBar
onTriggered: {
dialog.open();
}
}
]
Container {
topPadding: 30.0
leftPadding: 20.0
rightPadding: 20.0
ListView {
id:list1
dataModel:dataModel
listItemComponents: [
ListItemComponent {
StandardListItem {
title: {
qsTr(ListItemData.name)
}
}
}
]
}
}
} //page
attachedObjects: [
GroupDataModel {
id:dataModel
},
DataSource {
id: dataSource1
source: "models/employeelist.xml"
query: "/root/employee"
type: DataSourceType.Xml
onDataLoaded: {
dataModel.clear();
dataModel.insertList(data);
}
},
Dialog {
id: dialog
Container {
background: Color.Gray
layout: StackLayout {
}
verticalAlignment: VerticalAlignment.Center
horizontalAlignment: HorizontalAlignment.Center
preferredWidth: 700.0
leftPadding: 20.0
rightPadding: 20.0
topPadding: 20.0
bottomPadding: 20.0
Container {

Label {
text: "Add Employee List"
textStyle.base: SystemDefaults.TextStyles.TitleText
textStyle.color: Color.DarkBlue

textStyle.fontSizeValue: 4.0
}
}
Container
{
topPadding: 30.0
layout: StackLayout {
orientation: LayoutOrientation.LeftToRight
}
Label {
text: "Employee Name "
}
TextField {
id:nametxt
}
}
Container {
topPadding: 30.0
layout: StackLayout {
orientation: LayoutOrientation.LeftToRight
}
Button {
text: "OK"
onClicked:
{
var name=nametxt.text;
if(nametxt.text=="")
{
_model.toastinQml("Please enter a name");
}
else
{
_model.writeEmployeeName(name); //writing name to the employeelist.xml
nametxt.text="";
dialog.close();
dataSource1.load(); //loading the xml
}
}
preferredWidth: 300.0
}
Button {
text: "Cancel"
onClicked:
{
dialog.close();
}
preferredWidth: 300.0
}
}
}
}
]
}//navigation
When I add a name first time to the xml, the list shows nothing.Then when I add a name again, it displays the list.
Why is it so? Is there any mistake I have done?
Please Help!!
Thanks in Advance
Dhanya
