Issue with JSON in UWP WebView using C# to JavaScript not being read properly

This is rather perplexing. I'm converting an HTML5 game to UWP by using a WebView to host the game content and would like to back up from localStorage in the WebView and create a duplicate in the localStorage for the app as a whole (that is, from browser storage to package storage). This is of course an intended safety net in case the player craps out on hardware (as I obviously want the data to back up to the player's cloud storage) however something's not quite right. Specifically, the backups are written properly but when they're read back from the host app into the HTML5 portion using Javascript methods connected to the host through a WinRT component they're not having an effect on the localStorage in the WebView (which in turn makes it look like there's no save data, so the continue option is disabled).
Here's a code sample for what I'm doing:
var i;
for (i = -1; i <= 200; i++) {
var data = window.UWPConnect.getSaveFile(i);
var key = 'File'+i;
if (i === -1) key = 'Config';
if (i === 0) key = 'Global';
localStorage.setItem(key, data);
}
This first portion reads my WinRT component to load save data from the disk.
public void doSave(int key, string data) {
/*StorageFolder folder = ApplicationData.Current.LocalFolder;
StorageFile saveWrite = await folder.CreateFileAsync("saveData" + key + ".json", CreationCollisionOption.ReplaceExisting);
try { await saveWrite.DeleteAsync(); } catch { }
String[] lines = { data };
await FileIO.WriteLinesAsync(saveWrite, lines);*/
if (key == -1) { System.IO.File.WriteAllText(ApplicationData.Current.LocalFolder.Path + "\\config.json", data); }
else if (key == 0) { System.IO.File.WriteAllText(ApplicationData.Current.LocalFolder.Path + "\\global.json", data); }
else
{
System.IO.File.WriteAllText(ApplicationData.Current.LocalFolder.Path + "\\saveData" + key + ".json", data);
}
}
public void doStartup()
{
StorageFolder folder = ApplicationData.Current.LocalFolder;
for (int i = -1; i <= 200; i++)
{
try {
if (i == -1)
{
saveData[i] = System.IO.File.ReadAllText(ApplicationData.Current.LocalFolder.Path + "\\config.json");
} else if (i == 0)
{
saveData[i] = System.IO.File.ReadAllText(ApplicationData.Current.LocalFolder.Path + "\\global.json");
}
else
{
saveData[i] = System.IO.File.ReadAllText(ApplicationData.Current.LocalFolder.Path + "\\saveData" + i + ".json");
}
Debug.WriteLine(saveData[i]);
}
catch {}
/*Debug.WriteLine(File.Exists(SaveFile));
if (File.Exists(SaveFile)) {
try { saveData[i] = File.ReadAllText(SaveFile);
Debug.WriteLine(saveData[i]); }
catch { }
}*/
}
}
public string getSaveFile(int savefileId)
{
string data;
try
{
data = saveData[savefileId];
if (data == null) data = "";
Debug.WriteLine(data);
}
catch { data = ""; }
return data;
}
And this second portion handles the saving and loading from disk (which is taken from the WinRT component).

I think I figured it out. In the data reader where it loads and saves I had to use a different set of instructions on the WinRT side, so here's the new code structure:
public void doSave(int key, string data) {
if (key == -1) { System.IO.File.WriteAllText(ApplicationData.Current.LocalFolder.Path + "\\config.json", data); }
else if (key == 0) { System.IO.File.WriteAllText(ApplicationData.Current.LocalFolder.Path + "\\global.json", data); }
else
{
System.IO.File.WriteAllText(ApplicationData.Current.LocalFolder.Path + "\\file" + key + ".json", data);
}
}
public void doBackup(int key, string data) {
System.IO.File.WriteAllText(ApplicationData.Current.LocalFolder.Path + "\\backup" + key + ".json", data);
}
public void doStartup()
{
for (int i = 0; i <= 200; i++)
{
if (i == -1)
{
if (System.IO.File.Exists(ApplicationData.Current.LocalFolder.Path + "\\config.json"))
{
saveData[i] = System.IO.File.ReadAllText(ApplicationData.Current.RoamingFolder.Path + "\\config.json");
}
}
else if (i == 0)
{
if (System.IO.File.Exists(ApplicationData.Current.LocalFolder.Path + "\\global.json"))
{
saveData[i] = System.IO.File.ReadAllText(ApplicationData.Current.LocalFolder.Path + "\\global.json");
}
}
else
{
if (System.IO.File.Exists(ApplicationData.Current.LocalFolder.Path + "\\file" + i + ".json"))
{
saveData[i] = System.IO.File.ReadAllText(ApplicationData.Current.LocalFolder.Path + "\\file" + i + ".json");
}
if (System.IO.File.Exists(ApplicationData.Current.LocalFolder.Path + "\\backup" + i + ".json"))
{
backup[i] = System.IO.File.ReadAllText(ApplicationData.Current.LocalFolder.Path + "\\backup" + i + ".json");
}
}
}
}
public string getSaveFile(int savefileId)
{
string data;
try
{
data = saveData[savefileId];
if (data == null) data = "";
Debug.WriteLine(data);
}
catch { data = ""; }
return data;
}
public string getBackup(int savefileId)
{

try
{

if (data == null) data = "";

javascript function pass object with null values

I am doing master/detail using this article as a guide, my case is a little different as I have five different details for single master table and each one with totally different details/columns. I want my users to enter all rows in selected detail table and pass these rows with the master to the controller, but passed parameter is always null. I searched a lot without success.
Solution in this post did not work for me and a couple of others in different forums.
Here is my code:
//JobOrderMaster Action:

action screenshot shows null values
alert msg shows object received ok in js function

The problem is that You don't have the same names of properties in JSON (JavaScript side) and your class WorkOrderDetails in C#:
WorkOrderDetails
JSON
Category_Id
categoryId
Descriptions
descriptions
Qty
quantity
Make the same names in two of these types and it should be ok.
For example:
WorkOrderDetails
JSON
categoryId
categoryId
descriptions
descriptions
quantity
quantity

autocomplete to avoid tab operation for textbox

I am using Autocomlete to show the list of location which come from database. User get the list as expected. but instate selecting from list user just click on the tab button and control going to next button. I want to avoid TAB operation here.Any suggestion how i will do that .
Here is my function :
$(document).ready(function () {
src = 'LocationHandler.ashx';
$('#txtLocationName').autocomplete({
source: function (request, response) {
$.ajax({
url: src,
dataType: "json",
data: {
term: request.term,
type: $("#ddlDivision1").val()
},
success: function (data) {
Object.keys = Object.keys || function (o, k, r) { r = []; for (k in o) r.hasOwnProperty.call(o, k) && r.push(k); return r }
if (Object.keys(data).length == 0) {
$('#txtLocationName').val('');
alert('Location must be selected from the options.');
}
response(data);
}
});
},
min_length: 3,
delay: 300
});
});
My Handler class looks like
public class LocationHandler : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
string term = context.Request["term"] ?? "";
string type = context.Request["type"] ?? "";
// type = "FM";
List<string> listLocationNames = new List<string>();
string cs = ConfigurationManager.ConnectionStrings["EGLFormsDB"].ConnectionString;
using (SqlConnection con = new SqlConnection(cs))
{
SqlCommand cmd = new SqlCommand("spIARLocationNames", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter()
{
ParameterName = "#term",
Value = term
});
cmd.Parameters.Add(new SqlParameter()
{
ParameterName = "#locType",
Value = type
});
con.Open();
SqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
listLocationNames.Add(rdr["Name"].ToString());
}
}
JavaScriptSerializer js = new JavaScriptSerializer();
context.Response.Write(js.Serialize(listLocationNames));
}
public bool IsReusable
{
get
{
return false;
}
}
}

this is how i solve this.
$("#txtLocationName").keydown(function (evt) {
var keyCode = evt.keyCode || evt.which;
if (keyCode == 9) {
//evt.preventDefault();
//alert("TAB not allowed111111. Please select business unit number or name from Search box. ");
var textloc = $("#txtLocationName").val();
var specialChars = "{"
if (textloc.indexOf("{") >= 0) {
//no need to do anything
}
else {
evt.preventDefault();
alert("TAB not allowed. Please select business unit number or name from Search box. ");
}
}
if (evt.key === "Tab")
{
var textloc = $("#txtLocationName").val();
var specialChars = "{"
if (textloc.indexOf("{") >= 0) {
//no need to do anything
}
else {
evt.preventDefault();
alert("TAB not allowed. Please select business unit number or name from Search box. ");
}
}
});

Replace Java Applet with GWT

Hi I have the following class which would like to replace with stjs, but it seems it does not work for me, as stjs does not cover all applet libraries, any though if this is can be done thru stjs or any other technology? Thanks in advance
