To Reach A Variable From A Different Code-block Expression Than The Block Where The Variable Was Declared ?

Oct 25, 2010

I have 2 separate code-block asp.Net expressions in an aspx markup, with an html content between (span element in the example below). In the first code-block, there is "i" as an increment variable for the for loop.Then the code-block is cut with an html content.And another code-block expression is opened but as I see I can reach the "i" variable which was declared in the previous code-block.

So, how asp.net handles -compiles- the pieces of code-block experrions declared in the mark up? Does it check the semi-colons and generates some anonymous methods which will end up with many calls to Response.Write in the last place?
<p>
<%for (int i = 0; i < 30; i++)

WebService Debug Synchronization - Breakpoints Give Message "source Code Is Different From Original Version"

Oct 26, 2010

I'm fairly new to web service development, and I am really confused about how ASP.Net Development Server synchronizes with code during debug mode. When I make changes to my service, I cannot figure out how to propigate those changes so that my client can "see" them (I've been able to synchronize through a stumbling series of publishing the service, viewing the service in browser, etc... but I have a feeling there's a more reliable system than my random ritual). Here are the symptoms I'm seeing: After I've made a change to the code behind my service (Service1.svc.cs), started the application through the debugger and attached the debugger to the WebDev.WebServer.exe process as well, my latest changes are not executed, and my breakpoints are not hit (they have the message that "The source code is different from the original version." What really baffles me, though, is that when the ASP.Net Development Server notification pops up in my system tray, its physical path points to my project folder, so I don't understand how it could be looking at anything but my current code files.

AJAX :: Data In A Web Method Block?

Sep 3, 2010

[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]

public static string[] GetCompletionList(string prefixText, int count, string contextKey) {

// Create array of movies [code]..

Problem: The above code works great for me in getting the Autocomplete AJAX control to work. However, what I need is to define the string[] variable outside of the above block. What I'm looking for is the way to define such a variable as a global, or whatever the technical term in asp.net is for a variable that is persistent and recognized wherever it is used in the code-behind. without massive amounts of technical wizardry?

Custom HTTPModule - How To Tell When Writing Last Block Of HTML In Write Method

Jul 2, 2010

I have written an Http Module that hooks onto the Response.Filter property of the current request and does various replacements within the HTML before it is sent to the client.All the work is done in the Write method which is overriding Write in the base class Stream.

The Write method is called multiple times for a single response - the HTML seems to be written to the output stream in chunks. My problem is that I don't have an efficient & reliable way of telling if the current chunk is the last chunk (for why I want to know this see below). The only way I have come up with is to check if the chunk contains a closing html tag - but this is not very efficient or reliable.

The reason this is needed is that the module must add the "Refresh" HTTP header to the response, but only if the HTML fulfills certain conditions (and there are certain conditions that mean the header must not be added). So, only when the last chunk has been seen does the code know if the header can be added or not. So, I either need a test for the last chunk, or on each call to Write I add the header if the current block of HTML passes the test (if it has not already been added) or remove the header if the current block of HTML fails the test (if it has already been added).

So, is there a better way to test for the last chuck OR is there a way to test for a particular header being in the response and delete it (there doesn't seem to be a way to do this - only to append headers)?

How To Get A Listbox To Update After The Add Method Is Called

Mar 10, 2010

I am having a problem with getting a listbox to update after the add method is called. I am using an AsyncFileUpload control and as part of the AsyncFileUpload1_UploadedComplete I am creating a listItem and then adding that to the listbox. The item will not appear in the listbox. I have tried putting the listbox in an update panel and then calling the Update method on the panel from within the AsyncFileUpload1_UploadedComplete procedure and that too fails to update the listbox. I can call the Update method on the panel from a separate procedure and still the listbox will not update with the item added in the AsyncFileUpload1_UploadedComplete method.

Controller Method Not Always Called From $.getJSON Request?

Mar 9, 2010

I have a controller method that returns a jSON object and in one calling situation, it works and in another calling situation, it does not work. When the URL in my browser is this:

http://localhost:65247/Client -- it works.

But, when my url looks like this:

http://localhost:65247/Client/UserAdmin?id=6 -- it DOES NOT work

In a nutshell, clients have users. From within the client, I wish to work on a specific user (this is the UserAdmin view). In this case, the client id is 6. From within the UserAdmin view that was launched with Id=6, I then wish to select a user from a dropdown. The idea was to use javascript and $.getJSON to fetch data for the specific user so as not to have to refresh the entire page. I use this approach in other parts of the app. The only difference I can see is with the URL in the browser. It would appear the presence of parameters via the '?' is futzing things up a bit.

MVC :: Initialize Method Called Multiple Times?

Jul 6, 2010

I'm overriding the Controller.Initialize method to set some stuff before each ActionResult is executed, however I'm finding that the method is being called multiple times for each request (anywhere between 2 - 10 times). I'm running in Cassini.

My hunch is that it is running for all static files (images, css etc) as well as the requested action - although I may be wrong? I thought maybe something was wrong in my web.config but it all looks right to me.

.net - MVC LinkButton Equalization - Overloaded Index() Method Isn't Called?

Feb 4, 2010

I'm rewriting a Web Forms application as an exercise to learn some MVC skills.I have a number of LinkButtons on the original application which postback and raise a serverside event that rebinds data to a datagrid.

E.g.
Event handlers:
protected void lbtnOffset0_Click(object sender, EventArgs e)
{
[code]....

What I currently have in MVC is this:

<%= Html.ActionLink("CurrentYr", "Index", 0)%>
<%= Html.ActionLink("1", "Index", 1)%>
and

public ActionResult Index()
{
return View(MietController.GetMietByYearOffset(0);

[code]...
As the ActionLink renders an tag it doesn't postback so my overloaded Index() method isn't called. What are my options for doing this in MVC?

How Many Times Does HttpModule Init() Method Get Called During Application's Life

Jul 30, 2010

Web application initialization is as follows:

As we know when IIS receives the first request for a particular Asp.net application resource, IIS creates an instance of a HttpApplication (defined in global.asax codebehind).When this new instance is created it's initialization happens that also checks all configured HTTP modules.All modules are then instantiated and put in the application's Modules collection (of type HttpModuleCollection)modules are looped through and their Init() method is called (when they register for request events)

As far as I understand it the above scenario happens when a web application is started/initialized (hence application start event).What happens with modules?

Are they (re)instatiated on each request or reused from the Modules property on each consecutive request while the web application is alive? As I understand IIS and Asp.net they are reused through the whole life of a web application.

If they are reused, can we assume that their Init() method is actually a pseudo event handler for application start event? The thing is we can't attach to application level events within http modules. But if they are being reused we could use Init() as application start event and do whatever we'd put in global.asax instead.

Question,Can we assume that module's Init() method is called only on application start event? Could we use this assumption to i.e. register routes for applications whose global.asax codebehind we can't change? web.config is usually accessible and we can change it the way we want.Would this actually work?

Additional info,We can check HttpApplication code and check its InitModulesCommon() method. This one actually calls Init() of each registered HTTP module. What is more interesting is that this method is only used by InitIntegratedModules() and InitModules() methods. Which are both used only in HttpApplication.InitInternal() method. This is the basis of my assumptions, but I would like to know whether someone has abused IHttpModule.Init() for application start event.

MVC :: Can't Reach Controller - Javascript Library And Method Called From View

Jul 23, 2010

I have a javascript library and in there i have a method that is called from my view. Here it is:

<li><a href="javascript:void 0" onclick="deleteAll('image', '<%= ViewData["FileGroupId"]%>')"><div><%=GetGlobalResourceObject("default", "Delete_all") %></div><div></div></a></li>
and here is my js code in the javascript library:
var deleteAll = function(module, groupId) {
jConfirm(_deleteConfirmAll, _deleteAll, function(r) {
if (r) {
showProgress();
$.ajax({
cache: false,
type: "POST",
url: _baseUrl + "/" + module + "/deleteall/" + groupId,
success: function(msg) {
if (msg == '0') {
location.href = _baseUrl + '/' + module;
}
else {
jAlert(msg, _errorTitle);
}
hideProgress();
}
});
}
});
}
My problem is that i cant reach my controller. Here is my controller code:
#region common methods
List<.CMS.Core.File> GetList(int groupId)
{
List<CMS.Core.File> list = new List<CMS.Core.File>();
CMS.Core.FileFilter filter = new CMS.Core.FileFilter();
filter.GroupId = groupId;
int res = CMS.Core.File.Search(_connection, filter, ref list);
return list;
}
#endregion
public ActionResult DeleteAll(int groupId)
{
List<CMS.Core.File> list = GetList(groupId);
foreach (File item in list)
{
item.Delete();
}
return Json(list);
}
And at last her is my Index method
public ActionResult Index(int? id)
{
if (Request.IsAjaxRequest())
{
JsonPaging paging = new JsonPaging();
int offset = 0;
int page = 0;
if (!String.IsNullOrEmpty(Request.QueryString["page"]))
{
Int32.TryParse(Request.QueryString["page"], out page);
}
if (page > 0)
{
offset = (page * paging.PageSize) - paging.PageSize;
}
FileFilter filter = new FileFilter();
filter.Deleted = false;
filter.MaxRecords = paging.PageSize;
filter.Offset = offset;
if (!String.IsNullOrEmpty(Request.QueryString["keywords"]))
{
filter.FilterType = FilterTypes.AND;
filter.Name = Request.QueryString["keywords"].ToString();
}
if (!String.IsNullOrEmpty(Request.QueryString["sort"]))
{
filter.OrderBy = Request.QueryString["sort"].ToString();
if (!String.IsNullOrEmpty(Request.QueryString["direction"]))
{
filter.OrderBy = filter.OrderBy + " " + Request.QueryString["direction"].ToString();
}
}
if (id > 0)
{
filter.GroupId = id.Value;
}
List<CMS.Core.File> items = new List<CMS.Core.File>();
int results = CMS.Core.File.Search(_connection, filter, ref items);
foreach (CMS.Core.File current in items)
{
JsonItem item = new JsonItem();
item.Id = current.Id;
item.Name = current.Name;

}
return Json(paging, JsonRequestBehavior.AllowGet);

How To Make Sure That CreateChildControls () Method Is Called When Unit Testing Custom .NET Web Controls

Feb 10, 2010

I want to unit test my rendering engine for an ASP.NET app. I have some custom controls created in that app. Most of those control rely on having CreateChildControls() method called by the ASP.Net engine wheather during initial call or a postback.When running a test CreateChildControls() does not get called and the control is in an "invalid" state.

As a workaround to get the tests going I explicitly call some other public method that calls EnsureChildControls() in it. This in effect causes CreateChildControls() to be executed and the control being initialized properly (just as it would normally when hosted on web server). I would like to get rid of that extra method call and the control to still be in a proper state for testing.
