Timing Of Database Operations In Webpage Lifecycle?

Nov 9, 2010

According to the msdn documentation, as you can see on the diagram, a server control's "Data binding events" occurs after all "control changed events". So in the case of a DetailsView control, the ItemInserted event would happen before the database operation?

Finding Webpage Lifecycle In The ViewState Collection

Feb 8, 2011

When exactly is the view state accessible from the .Viewstate property of a control? From my observations, the closest event is on the Page.PreLoad event (at Page.InitComplete, Viewstate is still unavailable).

However, for controls that implement the IPostBackEventHandler interface the LoadValue() method is called and the .Viewstate collection is available (this occurs after Page.InitComplete and before Page.PreLoad).

Does anyone know of any additional events that can be used to know when Viewstate is available? Or any tricks (not excluding reflection on private/protected/internal members) that can be used to know if the Viewstate has loaded or not?

Web Forms :: Should Be Database Operations Call Asynchronously

Oct 4, 2010

I want to ask that what happens when I make a database request (using Linq-To-Sql). Active thread is blocked and waits for response, or it is used to process other requests?

Do frameworks like Linq-To-Sql or Linq-To-Entities handle this?

If I use Sleep() method on thread, is that thread blocked or is it used to process other requests?

Debugging Timing Out With IIS?

Apr 29, 2010

my client/iis (not sure which) usually times out after about 30s - 1 minute while im debugging (stepping through code) which not only causes me to lose my spot and have to start over (usually stepping faster, making more mistakes) but the IIS Debug session closes completely and I have to warm up the entire session again.

What's the best way to get more time out of a debugging session?

Session Keeps Timing Out?

Sep 4, 2010

My session keeps timing out in just a few minutes even though I've specified a 200 minute expiry.

In my web.config I've set the timeout for the forms and the sessionState. I've looked at some other similar questions on Stack Overflow but still can't suss this.

Web Forms :: Webpages Keep Timing Out?

Mar 6, 2011

we have a reseller web application that uses basically the same asp.net codes on different domains. However we replaced the cookies in the web.config files to the root domain of each domain and the timeout time to 1000

HOwever for the initial site that was setup, it runs well. But every additional site times out after about 2mins

I have looked through the web.config so many times to see if anything is conflicting but cant find anything.

Forms Authentication Timing Out After 1 Minute?

Dec 24, 2010

I'm using ASP.NET MVC 3 with the Authorize attribute, but it keeps kicking me to the logon page after 1 minute, but even though my expiration is set to a very high value, it times out quickly. I check the cookie in my browser and its still there and not set to expire until about a month later, and it's set to be persistent, so I'm not sure why it keeps booting me. It only happens on my published location, locally it works just fine.

var ticket = new FormsAuthenticationTicket(username, true, 500000);
var encryptedTicket = FormsAuthentication.Encrypt(ticket);
var cookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket);
cookie.Expires = ticket.Expiration;
Response.Cookies.Add(cookie);
web.config:
<authentication mode="Forms">
<forms loginUrl="~/Account/LogOn" timeout="7200" slidingExpiration="false"/>
</authentication>

Visual Studio :: Dataset Query Timing Out?

Jul 6, 2010

I have a query that, when run in SQL Server Mgmt Studio query analyzer window, completes in about 5 seconds. However, when I attach this query to a table adapter in visual studio and try to preview the data, I get an error that says:"Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."Please note, the dataset was successfully configured using the TableAdapter Configuration Wizard, so there didn't appear to be any syntax errors with my query. Also note that I have other datasets connecting to the same database that are working as expected, so it doesn't appear that it would be an issue with the server not responding. Does anyone have thoughts on what kinds of things, other than a query taking too long to run, that could cause this specific error?

Web Forms :: Timing Aspx Page Execution/generation?

Jul 2, 2010

I am trying to add some code that logs to a table the time a page has taken to generate, from the request coming in to the response given back. The easiest way to do this is through our master page as it can add the timings of every page.Where I'm a little unsure, is when to put the start and end timings.Currently, I set the start time in the page.unload and the end time as the last part of the page.load on the master page.The figures coming back seem ok, but I'm not sure if I am picking the earliest and latest possible times to get my timings?

Lifecycle To Access Viewstate?

Nov 8, 2010

In building custom controls, I've seen two patterns for using the viewstate. One is to use properties to disguise the viewstate access as persistent data.

public bool AllowStuff
{
get
{
return (ViewState[constKeyAllowStuff] != null) ?
(bool)ViewState[constKeyAllowStuff] : false;
}
set { ViewState[constKeyAllowStuff] = value; }
}

The other is to use private member fields and to override the Load/SaveViewState methods on the control and handle it all explicitly:

protected override object SaveViewState()
{
object[] myViewState = new object[2];
myViewState[0] = base.SaveViewState();
myViewState[1] = _allowStuff;
return myViewState;
}
protected override void LoadViewState(object savedState)
{
object[] stateArray = (object[])savedState;
base.LoadViewState(stateArray[0]);
_allowStuff = (bool)stateArray[1];
}

(I cut out a lot of safety checking for clarity, so just ignore that.) Is there are particular advantage to one method over the other? I can't see how they'd differ much performance wise. Version 1 is lazy, so I guess you save a bit if you don't need that particular value during a pass. Version 1 is also more abstract, hides the details better. Version 2 is clearer about when the data is actually valid and ok to read or modify (between the load and save) because it more clearly works within the ASP.NET lifecycle. Version 2 does tend to require more boilerplate code though (a property, a backing private field, and viewstate handling in two places) as opposed to Version 1 which combines all that into one place.

Preventing Page Lifecycle For One Control?

Dec 16, 2010

I'm using a file manager-type WebControl that does lots of postbacks. It's placed inside a Page that is relatively complex. I would like to prevent the WebControl from causing the whole Page to go through the lifecycle.

Is there any way to isolate the WebControl from the rest of the Page? The only way I can think of is sticking the WebControl in a separate Page and creating an iframe in the original Page. Unfortunately that also means my WebControl properties/settings are no longer in the original Page. If I want two instances of the WebControl with different settings, then I have to create a Page for each setting and reference the correct one in my iframes. Not quite as "drag & drop" as I would like.

Where In The Web Forms Lifecycle Can Re-authenticate A User

Jan 15, 2010

Here's the situation - Most of this ASP.NET Web Forms application (which uses a single master page for all pages) with Forms Authentication, has a standard session timeout, but there are some "modes" where we store an encoded cookie that links the user to their account.

I would like to manually check early on in the page lifecycle for the cookie, and if certain conditions are met, manually re-establish the user's authentication ticket/session.

Where's the best place to do this? Master page Page_Init? Global.asax BeginRequest?

C# - Page Lifecycle Stops After Command From ListView?

Feb 9, 2011

I have a ListView in a web form (c#/.net 4.0). There is an ImageButton in the ItemTemplate.

After a postback, the ItemCommand event fires... and then everythings stops. No other page events occur. (Actually there is one other thing: Dispose() from ExtenderControlBase runs right after the event code finishes - this site has some AjaxControltoolkit controls, though there are none on this particular page).

There are a lot of things involved here so it's not really practical to post all the code, but generally, is there anything that could cause this?

I am rebinding the ListView on each postback, because I'm handling paging on the server side. When I assign the data source to the ListView, it's initially going to have no rows. So at the time the command event fires, the DataSource has no data in it, since it hasn't yet been loaded from the database and rebound. I can't think why this would cause the entire page to just stop loading, though.

The template is just this:

<ItemTemplate>
<tr>
<td class="DataListRow"><asp:ImageButton ID="edit" runat="server" ImageUrl="~/images/nav/datagrid_edit.gif" CommandName="edit" />
</td>
// a few orther cells
</tr>
</ItemTemplate>

C# -remove Client Script Resource In The Lifecycle?

Dec 1, 2010

In a base class,the pre-render adds a Javascript to the page.In my derived class,I want to replace the Javascript with one of my own resource script.If the script is being added like this in the base class:

this.Page.ClientScript.RegisterClientScriptResource(typeof(GeomappingEditor), "SomeSpace.Resources.Scripts.Geomapping.js");

Then can I do something like this:

protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e);

//HOW TO OVERWRITE JAVASCRIPT FILE HERE?
}

The reason why I thought this may be possible is because sometimes Javascript is added onto a page with a key like this:

this.Page.ClientScript.RegisterClientScriptInclude("geomapping", this.ApiScript);
So I know I can add another script in the page with "geomapping" being the key and it will overwrite the previous script. But it does not seem there is a key like this for "RegisterClientScriptResource".Any ideas on how to achieve this?

Events - Dynamically Created Controls And Page Lifecycle?

May 10, 2010

I'm working on an ASP.NET project in which the vast majority of the forms are generated dynamically at run time (form definitions are stored in a DB for customizability). Therefore, I have to dynamically create and add my controls to the Page every time OnLoad fires, regardless of IsPostBack. This has been working just fine and .NET takes care of managing ViewState for these controls.

protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
RenderDynamicControls()
}
private void RenderDynamicControls(){

//1. call service layer to retrieve form definition
//2. create and add controls to page container
}

I have a new requirement in which if a user clicks on a given button (this button is created at design time) the page should be re-rendered in a slightly different way. So in addition to the code that executes in OnLoad (i.e. RenderDynamicControls()), I have this code:

protected void MyButton_Click(object sender, EventArgs e)
{
RenderDynamicControlsALittleDifferently() [code]

My question is, is this really the only way to accomplish what I'm after? It seems beyond hacky to effectively render the form twice simply to respond to a button click. I gather from my research that this is simply how the page-lifecycle works in ASP.NET: Namely, that OnLoad must fire on every Postback before child events are invoked. Still, it's worthwhile to check with the SO community before having to drink the kool-aid.

On a related note, once I get this feature completed, I'm planning on throwing an UpdatePanel on the page to perform the page updates via Ajax.
