C# - LoadControlState Not Getting Fired?
Jan 10, 2011
I'm having problems with a custom control (which inherits from a user control) - my LoadControlState isn't getting fired.
Well, to be precise: it gets fired normally, but when i override the page's LoadPageStateFromPersistenceMedium and SavePageStateToPersistenceMedium functions, it no longer gets fired.
Are there any typical reasons for the LoadControlState not getting fired that i should look into? Are there any preconditions for when it does get fired?

A breakpoint is set on FillForm() and this method is called two times but I can't explain myself why this happens. I have client side javascript code, when the form is being send, the onsubmit method is also called twice... Where do I have to search?! Is it a (known) bug? Think I could get it to work with this Thread: [URL] But why is the event fired within the onblur-event when it's fired anyway??

Application_Start and Application_End are called only once during the lifetime of the application domain - thus they aren't called for each HttpApplication instance
Application_Start runs when first user requests a page, thus when the first instance of the HttpApplication class is created, while Application_End runs when the last instance of an HttpApplication class is destroyed.
But what if at the time of application domain being restarted there wasn't any user requests and thus no HttpApplication instances created? Will in that case Application_End still be fired?

I'm developing an asp.net model -view-presenter (MVP), and to my surprise i see that when I click on the linkbutton in the window the Page_Load event is fired again. Is that normal? I'm used to webforms where we could just do a if (!Page.IsPostBack) if statement in the Page_Load. I did that but then no action happend when I clicked the linkbuttons in the window.

SelectedIndex_Changed event occurs when selection changes, and selection is changed or not is decided by comparing dropdowns current selectedIndex and its value in viewstate.
When we changes dropdown's selected Item using Javascript, it does not change the viewstate's value (which is previously selectedIndex). Now if you change dropdown's selectedIndex to any new index it will work fine, but if you select the previously selectedIndex (which we reset using javascript), then postback will occur, but selectedIndex_changed function will not get fired because in viewstate of dropdown, selectedIndex is same as the Index we select after resetting it using javascript.

I'm trying to implement the cascading dropdown from the toolkit. I need to get the count in a sub category dropdown, if it's zero then I turn off the visibility of the sub category.If I use the javascript OnChange event then my script fires before the web method, so I need to know how to fire my script AFTER the web method has fired please.
My demo page: http://bit.ly/92RYvq
Below is my code and the order I need it to fire.
[WebMethod]
public CascadingDropDownNameValue[] GetSubCats1(string knownCategoryValues, string category)
{
StringDictionary kv = CascadingDropDown.ParseKnownCategoryValuesString(knownCategoryValues); [Code]....

We are obesrving strange problems when performing sress test of our applciation. We use Application_BeginRequest and Application_EndRequest to log the beginning and end of the web request, together, with the thread id.
However, from our logs, we see that Application_Begin_REquest is not being fired:
We use the following code to do the logging in global.asax.cs:
protected void Application_BeginRequest(object sender, EventArgs e)
{
string url = ""; [code]....
This is our log file. Urls are omitted The 00013 column is thread id.
14.12.10 21:41:25.042 00013 00000 Request: 172.23.26.41
14.12.10 21:41:25.068 00013 00000 End request: 172.23.26.41
14.12.10 21:41:25.212 00013 00000 Request: 172.23.26.41
14.12.10 21:41:25.223 00013 00000 End request: 172.23.26.41
14.12.10 21:41:30.974 00013 00000 End request: 172.23.26.88
You can see that there are two "End request" in the last two lines, but there is no (Begin) Request for the last log line.Our Dbg.WriteLine uses System.Diagnostics trace listeners to ouput data to the file.
Environment: Windows Server 2008 R2, ASP.NET 3.5
This only happens when performin stress test. CPU utilization is around 60%, there are max 10 concurent requests executing.
UPDATE: I have found out that some other also did have similar problems (althoug in different configuration:
http://forums.iis.net/t/1154954.aspx)
Matej
UPDATE#2: This night be related to fact, that Thread.GetHashCode() which is used to print out the thread identifier in our log fies could change. See ASP.NET - Thread.GetHashCode() changes

I have Asp:TextBox,Asp:RegularExpressionValidator and Asp:RangeValidator on .aspx page.
These two validators have ControlToValidate value equal to textBox Id.
RegularExpressionValidator have validation Expression such that it allows only number.
Range validator have maximum value ="100" and if I enter any text then both validators get fired .
Logically only RegularExpressionValidator should fire if I enter any textvalue.
Is there any property of Range validator such that it check for numeric value to compare and disbled if value entered in textBox is some text so that no handling of event(Client side and Server side both) is required.

I have an update panel in my ASP.NET web form with a trigger that will fire a click event when the contents within my update panel is updated (it's a grid view with fields). The event that is fired when then take the changes user made and do some calculation and then update another update panel with that information. This is all fine and dandy when the user tabs along the form and fill out the form in a orderly fashion before hitting any buttons on the page.
If a user accidentally hits another button on the page while changing the content in my grid within the update panel, for example, the user enter a value in my grid view control, without tabbing, the user click the save button. Logically, i believe that the trigger should fire the click event first (event A), and then the save button event (event B). But, consistently I haven't seen event A gets fire correctly while event B gets fire all the time. is there a way to ensure event A always gets fired before event B? also if event A update another update panel without the page will event B fire after the update is complete?

i was debugging a test page when i noticed that its init and load event handlers are being called twice.
i found out by search that this may arise due to some html tags which im not using in my page,
also some line:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load,Me.Load
may cause this problem.
i use c# in the code behind aspx, if such line is the problem, in which file should i look for?

I have a HttpModule that hooks on the EndRequest Event on a IIS6 with a wildcard handler registered and it works fine as long as the request ends on a .aspx page, but NOT if the url is missing (404).I guess it's because of the staticfilehandler ends the request, but is there any good solution for this problem ?I have tried the same solution in IIS7 (pipeline mode) and there it works fine.

I have a gridview that includes dynamically created dropdownlist. When changing the dropdown values and doing a mass update on the grid (btnUpdate.click), I have to create the controls in the page init so they will be available to the viewstate. However, I have several other buttons that also cause a postback and I don't want to create the controls in the page init, but rather later in the button click events.
How can I tell which control fired the postback while in page_init? __EVENTTARGET = "" and request.params("btnUpdate") is nothing
