State Management :: Class Object Available To Multiple Events In The Code Behind?
Sep 1, 2010I am trying to incorporate AJAX in my web project for the first time and it isn't working. I don't know how to instantiate a class once and use AJAX to update the dataset numerous times before updating the database changes using a postback.
My project is to learn AJAX with a class object. Clicking the button is supposed to increment a count by one using a class to store the count. Here is my class:
[Code]....
Here is my HTML code:
[Code]....
And here are my button click event code snippets:
[Code]....
My problem is that as I step through the code (after clicking on the second button) it instantiates a new class object each time which returns a value of 2 every time. I have tried to fix the problem by putting my counter class instantiation in the pageload event using "If Not IsPostBack Then ..." but my probem there is that the button click event block of code would not recognize the cCount class - it put the blue lines under the cCount
My goal is to have the class object available to multiple events in the code behind: especially using AJAX to build records in one of my DataSet tables Does anyone know how to handle this?

State Management :: Maintain Query String Parameter In All Pages - It Gets Lost In Subsequent Pages
Aug 9, 2010In my Application_BeginRequest I have code that gets query string value ?c=FR or ?c=US and store it in cookies.Based on query string value I have either US or FR,locale is selected from locale table.If ?c=FR then locale will be fr-FR and if it is US then locale will be en-US.My code is below.
void Application_BeginRequest(object sender, EventArgs e)
{
LocalizationInfo loc = GetLocalizationInfo();
if (Request.Cookies["Localization"] == null)
Response.Cookies.Add(new HttpCookie("Localization"));
Response.Cookies["Localization"]["Country"] = loc.Country;
CultureInfo objCI = new CultureInfo(loc.Locale);
Thread.CurrentThread.CurrentCulture = objCI;
Thread.CurrentThread.CurrentUICulture = objCI;
}
public static LocalizationInfo GetLocalizationInfo()
{
string countryCode = "";
string sLocale = "";
if (HttpContext.Current.Response.Cookies["Localization"]["Country"] != null)
countryCode = HttpContext.Current.Response.Cookies["Localization"]["Country"];
if (!string.IsNullOrEmpty(HttpContext.Current.Request.QueryString["c"]))
countryCode = HttpContext.Current.Request.QueryString["c"];
if (countryCode == "")
countryCode = "US";
sLocale = HertzRent2Buy.DataProvider.ListData.GetLocale(countryCode);
LocalizationInfo ret = new LocalizationInfo();
ret.Country = countryCode;
ret.Locale = sLocale;
return ret;
}
public struct LocalizationInfo
{
public string Country;
public string Locale;
}
Now when I run the project and in query string I set [URL] then for the very first page(home page itself) it shows me French translation,but on subsequent page,that query string parameter ?c=FR is lost and hence it shows be English translation not French translation since it does not pickup French resx file.If I manually append ?c=FR in subsequent page then it shows the French translation.Is there is way how I can make that query stringparameter available in all pages.Structure is there to hold Country and locale variables. In all pages I am calling GetLocalizationInfo() method as follow
LocalizationInfo info = some.DataProvider.Globalization.GetLocalizationInfo();
And I create instance info to pass locale and country as parameter. GetProductDetails(id,info.Country,info.locale). why my query string parameters get lost on subsequent pages.

State Management :: Dynamic Controls In A Page With Two Master Pages
Apr 12, 2010I have a nested master page that I use for multiple pages. There is a ContentPlaceHolder that is used for only one page, but it is not shown until after the first postback and some validation. I was first trying to use static controls and set the Visible property on the ContentPlaceHolder to true after the postback and that did not work at all. Then was messing with the visible properties of the Individual controls inside the ContentPlaceHolder which also did not work. I have the EnableViewState set to false for the Page and each of the controls including the ContentPlaceHolder. Is there a better way to do this? I can post my code if need be just wanted to see if there was a better solution to this before I did.
