Select Item from Listview using iteminvoke in Javascript.

Question

 Hello, I have a ListView with items. I am trying get clicked item from Listview using "iteminvoked".

    <div id="listView_Id" data-win-control="WinJS.UI.ListView" 
         data-win-options="{
                itemTemplate: select('#smallListIconTextTemplate'),
                selectionMode: 'single',
                tapBehavior: 'none',
                layout: { type: WinJS.UI.GridLayout }
            }">
    </div>

Here ListArray is array of values with filenames picked using 'FilePicker'

                dataList = new WinJS.Binding.List(listArray);
                var listControlDiv = document.getElementById("listView_Id");
                var listControl = listControlDiv.winControl;
                listControl.itemDataSource = dataList.dataSource;

I set ListView dataSource from JS file rather than HTML file by fallowing this question.

I created handler like this.

        document.getElementById("listView_Id").addEventListener("iteminvoked", doClickItem, false);

 But unfortunately, My doClickItem handler doesn't call at any way. While in same manner select item from Listview which is working Fine.

Here is my complete project to try Thanks

Thanks

Hi GEVENDRAK,

I tried your project, and it works with right click event but not left click. I think this is because you set "tapBehavior" as none which block the tap event. Take a look at this: http://msdn.microsoft.com/en-us/library/windows/apps/hh701303.aspx

But you should also be aware that only one MessageDialog is allowed during the app life, in your case, you open two MessageDialog at the same time, one for doClickItem and one for doSelectItem, a "Access denied" error message will be thrown. What I've done is to comment some of your code, works fine now.

    function doClickItem(eventInfo) {
        var listView = document.getElementById("listView_Id").winControl;
        var indexSelect = listView.selection.getIndices();
        var dlg = new Windows.UI.Popups.MessageDialog("Clicked Item Index: " + indexSelect);
        //dlg.showAsync();
    }

 Oh.. My Bad, Now only I realized that.

I have another doubt here. I know it is not proper way to ask another one here; 

But it is relevant to Listview. When I click on Listview I want to navigate to another HTML page(Page Control).

 Using this I am getting selected Item.

function itemInvokedHandler(eventObject) {
                eventObject.detail.itemPromise.done(function (invokedItem) {
   var index = invokedItem.index;
}

Using JavaScript how can I call another JavaScript page with this value "index". If my question not clear please ask any further info regarding this.

Thanks Jamles,
