C# - Fire Events And Methods Automatically -according To A Schedule?
Dec 20, 2010
Well, I'm sure this is not the first time to see this question. and TBH you can find this question answered on many other websites and blogs -not only here-
But I never saw a complete answer for this question, I mean no one talked about the advantages and the disadvantages. no one shared a real experience.
Although Quartz.NET seems like a good solution but yet, there's no enough reviews or a good comparison between the different ways to achieve such a thing.
As far as I read about it I found this are the possible ways of doing this :
Using a: Web Service, Windows Appliction, Console Application, Quartz.NET.
Examples of stuff I want to achieve with the scheduled or automatic methods/events are like archiving after a certain period, auto deleting/moving records in the database, setting a property of an object after a certain time, automatically run some methods according to my holiday schedule.
I hope you'd share your experience either with one of those approaches or share a new way of doing this.

Can we specify two different methods as SelectMethod of ObjectDataSource at two different events?
I need my Objectdatasource to get filled with one method while at button click event I want to fill it with other overloaded method.
Both the methods have same name and return same data type but they have different input parameters.

I have a large application and I'm going to enabling short-cut key for it. I'd find 2 JQuery plug-ins (demo plug-in 1 - Demo plug-in 2) that do this for me. you can find both of them in this post in StackOverFlowMy application is a completed one and I'm goining to add some functionality to it so I don't want towrite code again.So as a short-cut is just catching a key combination, I'm wonder how can I call the server methods which a short-cut key should fire?
Update: here is the scenario. When User press CTRL+Del the GridView1_OnDeleteCommand so I have this
protected void grdDocumentRows_DeleteCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
try
{
DeleteRow(grdDocumentRows.DataKeys[e.Item.ItemIndex].ToString());
[code]...

is there any tools within VS2008 or Free 3rd Party tools where i can generate a Diagram of Class Methods and Code Behind events. think of the Table Diagram of SQL, it will show all fields, Primary Keys and to what table it is connected via foreign keys, etc.That is what i wish to make, in a much faster way, where it will show all class and within it is all the methods then linking them are the Code behinds and the event where the class is called.

What I did is, I have made 2 user controls. One control is inside the other.
NoW one control has a buttton and a data grid and datalist in it. When pressing button I am filling datagrid while datalist visiblity false. This is working fine. But now when I press some link button in datalist data, it should call item_command event but it is not calling.
I have also used a Updatepanel as a wrapper(all controls are inside it).

I have a Page that does a LoadForm("blah.ascx"). The Page does have a ModalPopupExtender on it (It was on the ascx originally but I moved it to the Page as a test, doesn't work either way). There is a Loop here so the LoadControl() will be called multiple times and will put multiple instances of the ascx on the Page.
Blah.ascx has some buttons on it but when I click the buttons the click event does not fire and the Page gets reloaded without the control on it anymore.
The Page.Page_Load event does fire. And yes, I have the LoadControl() inside an Not IsPostback check. Just the controls events, including Page_Load, do not fire on postback, only on initial load.

A group I am in at school is developing a website for a client. It needs to be able to send weekly emails out to all users, as well perform many other scheduled tasks.My question is: what is the best way to fire events from classes within the solution with a timer? I've read that a Windows Service can be used...?

So I have a page with an UpdatePanel and some controls in there. When I explicitly type/copy+paste the page's address into the address bar, let VS navigate there for me, or follow a link to the page, all of the AJAX works fine. But if I refresh this page, the JS on the page initiates the async postback, but the appropriate event is never called on the server (although Page_Load is) and the client never recieves the markup sent back by the server. This issue seems to be limited to Firefox 3.6 (Gecko build 1/15/2010)(doesn't happen in IE8). I have yet to try on other versions of Firefox.

I'm building a library of custom controls. My controls are inherited from CompositeControl. Depending on the user's answer I have to insert more custom control. I have a PlaceHolder (_ph) passed in from the client code. I insert my controls into that PlaceHolder.
My problem is the control I inserted in the event handler does not fire its event, but it fires the parent event. For example, if I have an EddDropDown A, and the user picks an answer, I have to create EddDropDown B and C in edd_SelectedIndexChanged. When I pick an answer for B, it fires SelectedIndexChanged for A instead of B.
I think it has something to do with entering the page cycle late.
this is an example of my controls:
using System;
using System.Collections.Generic;
using System.Collections;
using System.Linq;
using System.Text;
[Code]....

I have created a custom web control. In that control on CreateChildControls method i dynamically create a Table add rows to it which contains a ImageButton and i am trying to attach an event to this ImageButton but the event never fires?
I tried on Init method too it does not work . The code goes like this on CreateChildControls
I create a Panel . The i create a table with data and an imagebutton on it I add this table to the created panel I add this Panel to the Controls.Add method.
I have also observed that if i add a control directly to the Controls.Add() method and attach an event it works fine .
Meaning ,
1. Create a button attach an event handler
2. Add to the Controls.Add() method
On doing the above it works fine . Only the child controls events do not get fired is there anything that i am missing ??

I am trying to fire one event out of two avalible events based on a check box selectoin, I have already registered the two events in the page_load() and i check if the check box is checked (checkbox is located within a gridview) then i un-register one of the events and just keep one events registered as following(Only relative part is shown):
[Code]....
I am trying to fire one event only based on the checkbox selection. I tryed to debug and noticed that, in fact, both evetns always get fired starting first with Button_SessionStartOrEnd_StartSessino and then Button_SessionStartOrEnd_EndSessino. So how can i fire one event only? please note that my code to check if the ckeckbox is checked within the girdview works fine.

For some reason I can't get the button event to fire...
This is my Accordion:
[Code]....
I dynamically add the panes and buttons...
[Code]....
These two should get fired - but they dont:
[Code]....
I read somewhere that I should add the button to the UpdatePanel
[Code]....
But when I do I get this error :
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

I'm working on a questionnaire type application in which questions are stored in a database. Therefore, I create my controls dynamically on every Page.OnLoad.This works like a charm and ViewState is persisted between postbacks because I ensure that my dynamic controls always have the same generated Control.ID.
In addition to the user control that dynamically populates the questions, my questionnaire page also contains a 'Status' section (also encapsulated by a user control) which represents the status of the questionnaire (choices are 'Complete', 'Started' or 'In Progress'). If the user changes the status of questionnaire (i.e. from 'In Progress' to 'Complete'), I need to postback to the server because the contents of the dynamic portion of the questionnaire depend on the selected status.
Some questions are always present regardless of status, and yet others may not be present at all for the selected status. The point is, when the status changes, I have to postback to the page and render the right set of questions. Additionally, I need to preserve any user entered values for those questions which are 'always available'.
However, due to the page life cycle in ASP.NET, the 'Status' user control's OnLoad, which contains the correct status needed to load the right questions from the DB, doesn't get executed until after the 'dynamic questions' user control has already been populated (with the wrong/stale values).
To get around this, I raise an event from my 'Status' user control to the main page to indicate that the Status has changed. The main page then raises an event on the 'dynamic questions' user control. Since by the time this event bubbles up, the 'dynamic questions' user control has already loaded the 'wrong' questions from the DB, it first calls Controls.Clear. It then happily uses the new status to query the database for the 'correct' questions and does a Control.Add() on each. FYI, Control.IDs are consistent across postbacks.
This solution works...sorta. The correct set of questions for the selected status do get rendered; however ViewState is getting lost for those 'always available' questions. I'm guessing this is because the 'dynamic questions' user control calls Controls.Clear when responding to the status changed event. This must somehow kill the association between ViewState and my dynamic controls, even though the Control.IDs are consistent.
This seems like such a common requirement, I'm virtually certain there is a better, cleaner and less error prone approach to accomplish this. In case its not plainly obvious, I haven't been able to grok the ASP.NET page life-cycle despite working with it for the last year.

I have a textbox on an asp.net page. I use a barcode scanner to get the barcode number into that textbox. I need to then automaticaly fire an event directly after the text box recieves that input. the only event that is exposed is the TextChanged event which doesnt achieve what i need. I am using c# for the code behind.

I'm new to ASP.net 3.5 and testing functionality before developing an asp.net web site. I created a page with a formview. I added several text boxes. I created an event on the FirstName_TextChanged event and added a stop in the sub. When I open the page in the browser and type in some text in the FirstName and press tab, nothing seems to fire.
1) Is this supposed to fire on the client side when text is changed?
2) If so, would the vb.net code entered work like Javascript code on the server?
3) If so again, is it possible to update another textbox based on the text entered into the FirstName on the Client Side (would do this in Javascript in Classic ASP)?
I think I'm totally confused. I've been searching web for article about how to do this.

I have a ListView control on a page that I need to support inline editing and inserting. Before I put it inside an update panel, everything was fine. As soon as I put it in an update panel, I seem to lose theOnItemUpdating, OnItemCanceling events. The OnItemEding event still fires, though.I am doing all updating, inserting manually.

I'm using a standard GridView control inside of a web form. The web form uses a master page. The application is running within sharepoint (wss 3.0) environment. When i attach both the OnRowCommand and OnRowDatabound events to the gridview as shown in the markup below, only the OnRowDataBound event fires. The OnRowCommand never gets hit. When i press a button on a row, it posts back but never hits the onRowCommand event and simply falls through and repaints the page . However if i remove the OnRowDataBound event, the OnRowCommand event starts to fires correctly. I've tried a number of things...1. Hooking up the events in code instead of markup. (inside of PageLoad or PageInit)2. Changing the order in which the events are attached.
