I can't understand why the method LoadViewState() is not called after the postback in my code below.After label1 cahnges its text the "__VIEWSTATE" hidden field is modified, but LoadViewState() is not called.

I am creating an Asp.net web site which will support dynamic data. When I am creating a dynamic web site from Scratch (from template in VS) all is working fine. But when I am trying to add dynamic entity (.edmx) file and running the application I am getting following error
"The method 'Skip' is only supported for sorted input in LINQ to Entities. The method 'OrderBy' must be called before the method 'Skip'. "
Anyone with similar conclusion? GridView does not databind/refresh upon postback unless the postback is called by itself?
View 1 RepliesI'm debugging right now and it seems the Wizard.ActiveStepChanged method is called BEFORE the Page_Init method?!?
I've tried it several times now.
If thats the case: what is called BEFORE Wizard.ActiveStepChanged?
I want to use a function in the code file of ASP.NET such that everytime the function is called, its value increases by 1.I thought of a way but it didn't fully work out. I created a class for this and used a static variable in that but the lifetime of static variable in asp.net is till the time the app does not close.
public class Class1

public Class1()[code]....
How code a time delay before the next method is called? I have the following but I don't think it's waiting 10 seconds before calling CallMethod(). Thread.Sleep(10000); CallMethod();

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.

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.
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.
In one view (view1) there is a text box and a button beside it. i click on that button, i am popping another view (Create view) as a seperate window. in create view i am entering some values and creating a record in db. out of these values one value i have to send back to "View1". how can i send this value? i am opening view2 from view1 like
<input type="button" value="Get ID"
onclick="window.open('<%=Url.Action("Create","Controller1") %>',
'','scrollbars=yes,width=800,height=800,resizable=yes');"
/>
View2 contains some fields like Name,Email etc... and I click "Create" to call HTTPPOST. there i add the values to db including a generated guid. i want to send this ID to view1.
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?
i have two dropdownlist (Country, and State) so when the user select the "country" the "state" will be filled.
So on postback the ajax will work, and i have some javascript function that called on thIe page load.
the javascript didn't called.
In a project of mine I dynamically create controls and add them to the nodes of a radtreeview (a control by telerik) in theLoadViewState event. By the end of this event everything seems fine, but as soon as the
Page_Load event fires the controls have disappeared. No code of mine is executed during this phase.
I'd love to know why this is the case,
When trying to edit the word before the delimiter the service method is not even called in IE but works fine in Chrome.
As an example, while '$' is set as a delimiter;
$csAux.Value$csNeedsPO.Valu
Now, editting the word
csNeedsPO => the autocomplete populates as expected succesfully.
csAux.Value => doesnT trigger the method in the background.
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.
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;
item.ImageText = current.ImageText;
item.Aperture = current.Aperture;
item.TakenOn = current.TakenOn;
item.Camera = current.Camera;
item.ExposureTime = current.ExposureTime;
item.FocalLenght = current.FocalLenght;
item.Tags = current.Tags;
item.Url = current.Url;
item["Active"] = current.Active.ToString();
item["Created"] = current.Created.ToString();
paging.Items.Add(item);
}
return Json(paging, JsonRequestBehavior.AllowGet);
}
else
{
ViewData["FileGroupId"] = id;
return View();
}
}
iam using the Jquery Uframe with asp.net project.Iam getting a postback problem here.
In side the uframe ,button control getting postback the page even the client side method call also.
i tried with the Html button Control also by setting the type="submit" ,iam facing the same problem.
And I got very limited reference about the uframe(codeflex,codeProject).
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.
I am working on a really old site and the following line is causing an error
Code:
Dim newFile As FileStream = New FileStream(Server.MapPath(sSavePath + sFilename), System.IO.FileMode.Create, System.IO.FileShare.ReadWrite)
I cretated my own server control (a dropdownlist) and thus my own LoadViewState and SaveViewState methods. When is the LoadViewState called? I added the control to my page and looked when the methods are called. Only the SaveViewState is called when the page is requested, LoadViewState is not. Do I have to call it manually?
View 2 Repliescan i get a value of a selected radio button in LoadViewState event of the the WebControl and how? All the components are generated in codebehind, so i have those controls:

protected override void LoadViewState(object o)
{
action = rbl.SelectedValue;
action2 = rbl.SelectedItem.Value;

I have a table with columns songID, Album, Artist and title. I have created a method called Updatesong() in data access layer. The SQL qerry in UpdateSong() method is
UPDATE Music
SET Title = @Title, Album = @Album, Artist = @Artist
WHERE (Title = @Title)
In a web page I have called the UpdateSong metod on a button click as
protected void Button3_Click(object sender, EventArgs e)
{
int SongID = Convert.ToInt32(musicAdapter.UpdateSong(TextBox3.Text.ToString(), TextBox4.Text.ToString(),[code]...
Whatever I'm changing in the textbox are getting updated except title column. I dont no whats wrong in that. If I change the SQL querry in tableadapter as

SET Title = @Title, Album = @Album, Artist = @Artist
WHERE (SongID = @Original_SongID)
I get an error saying "No overload for method 'UpdateSong' takes '10' arguments".
