VS 2010 - Event Handler For A Button Created Programmatically
Jan 25, 2012
I need to generate a button way after the page loads but I can't work out how to deal with the Event handler. If I do this when the page loads as shown bellow it works as intended but if I use the exact same method in a button it fails. (it creates the button but when I click the button it just disappears instead of showing a msgbox."I know I shouldn't use Msgbox in a web form but I only do it as a test then remove it"
Code:
Partial Class Default3
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim mybutton As Button
mybutton = New Button
mybutton.Text = "Submit"
[code]...

I'm trying to manually create a button and add a Click event handler for it in code. However when the button is clicked the event handler doesn't seem to react on event (or event isn't called).
we tested the code in Visual Studio 2008 and everything worked just as it should. And I'm using Visual Web Developer 2005 XE. So I assume that I'm missing something to be done manually being in VWD 2005 XE, or the problem is in VWD 2005 XE it self.
here is what I'm doing:

Does anyone have a good vb example of adding an "onClick" event to a button that is dynamically added into a templatefield of a gridview. MSDN just says to use the addhandler statement with no other good info for a 'dynamic' scenario:

I'm dynamically creating a table on my page with rows and controls. It looks like a gridview but it's not (it should've been, but too late now, seriously). I have a first name, last name, date of birth, etc. I want each row to have a button to add rows underneath it. So I create an event handler each time I create a new row and assign it to the click event of a button contained in the row. But it's not getting called.
Is it correct that the event handler doesn't stay established because the buttons are dynically created and are lost when the page posts back?
Code:
ImageButton addDependentButton = new ImageButton();
addDependentButton.ID = ADD_DEPENDENT_BUTTON_ID_BASE + currentSubscriberIDAsString;
addDependentButton.ImageUrl = "/Images/btnAdd.gif";
addDependentButton.Click += new System.Web.UI.ImageClickEventHandler(this.AddDependentButtonByRow_Click);
Control[] addDependentArray = { addDependentButton, addDependentDropDown };
WebControlUtilities.AddMultipleControlCellToRow(currentRow, addDependentArray, Constants.CSS_CLASS_TABLE_TEXT_NORMAL);

I need to run a SELECT box [on]change handler after changing the selectedIndex.
I see the selectBox._events['change'][0].handler() method added by $addHandler, but what is the ASP.NET Ajax way to raise it as an event?
The backup plan is to set sel.onchange directly and skip ASP.NET Ajax events completely.

I have a question connected with controls and event handling. Lets say I want to create a LinkButton.
protected void loadLinkButton()
{
ContentPlaceHolder content = (ContentPlaceHolder)this.Master.FindControl("MainContent");
LinkButton lnk = new LinkButton();
lnk.ID = "lnikBtn";
lnk.Text = "LinkButton";
lnk.Click += new System.EventHandler(lnk_Click);
content.Controls.Add(lnk);
}
Here is the event handler:
protected void lnk_Click(object sender, EventArgs e)
{
Label1.Text = "ok!";
}
If I run the loadLinkButton function inside Page_Load everything is ok. But when I try to run the loadLinkButton by clicking simple button, link button is created but event is not handled.
protected void Button1_Click(object sender, EventArgs e)
{
loadLinkButton();
}
I there any way to solve it? Or loadLinkButton must always regenerated on Page_Load, Page_init etc.

I have a create user wizard on my page and in the event handler (Created User) I get extra information from the user via textboxes within the aspx etc.
I then do a response.redirect to another page.
What I want to happen is this
When the CreatedUser Event is fired, I want a Modal Popup to show up with a message Processing your registration.
once the registration code is processed it will close and the users get redirected.
On my ASPX I have the Modal PopUp and a Panel.
In the code behind in the handler I put ModalPop.show()

Creating a list of users with a "Delete" linkbutton next to each". Seems I got it all wrong (again..away from webforms a long time).
Here's what I do:
Building a list of users with delete buttons:
Code:
foreach (var user in users)
{
var usr = user as UserInfo;
var row = new TableRow();
var cell = new TableCell();
[Code] ....
The "Delete""event handler:
Code:
protected void btnRemoveModUser_Click(object sender, EventArgs e)
{
var button = sender as LinkButton;
var userController = new UserController();
var user = userController.GetUser(PortalId, int.Parse(button.CommandArgument));
RemoveUserFromRole(Enums.KnowledgebaseRole.KB_Moderators, user);
}
I got a hunch though it's because of the when/where I'm loading that list of users. I call the function (getting a list of all users, clearing the table and populate it again):
In the page load, if not a postback.
Every time the "Add user" function have been called (that works fine).
Every time the "Delete user" function are called.
The last will not delete the user (still in database) but reload the ^&* form without any users.
I just found that the delete handler does not get called at all, but the button post back the form, so my list of user's don't get loaded.

I have a button in my aspx file called btnTest. The .cs file has a function which is called when the button is clicked.
btnTest_Click(object sender, EventArgs e)
How can I call this function from within my code (i.e. without actually clicking the button)?

I need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. I´m looking into doing this with button fields right now but I´m curious on how this can be accomplished?

Is there a technical reason for the existence of Page.PreLoad or is this just convenience to have a place where you can neatly place code that always have to be executed before the Load code? Is there a difference between adding code in the PreLoad event handler and adding code at the top of the Load event handler? And what would be a typical scenario where you use PreLoad?

I understand I need to load my dynmaic control on every postback and preferrably in Page_Init(). But my dyanmic controls are loaded from a dropdownlist selectedindexchanged event handler. Now after any postback, my dynamic controls are gone. How would I force it to load on every postback ?

I will describe my problem in simple way so it's not exactly what I'm trying to do but the idea is the same.Here is the problem:
I create dynamic buttons from code behind.I get some id from query string,create button with that id ,dynamic add event handler to click event,and add button to placeholder.I store the list of id-s in session and in page load method recreate these buttons and add to placeholder.One of the id-s is CurrentId and it's also stored in session.Buttons click handler do something like this
Button b=(Button)sender; Session["CurrentId"]=Convert.ToInt32(b.ID);
In page load when I create buttons I want to set button text property different from others if id==Convert.ToInt32(Session["CurrentId"]) when list of id-s are gotten from session.But problem is that click event handler is called after page load,and when I create buttons in page load ,CurrentId in session hasn't been channged by click event handler.Can you suggest any solution to this situation?

The below shown Tree view are dynamically created link buttons.
These link buttons should be created DYNAMICALLY.
I tried to create dynamically and its working fine for 1 and 2 case.
But I am not able to get 3 case dynamically when i clickon from 2 case.
If I click on Products Link Button it'll display all sub products(i.e, computers, mobiles,...) and
if I click on computers and then only it should display all other sub products like Keyboard, Mouse,...
lly, if I click on Mobiles and then only it should display all other sub products like Nokia, Samsung ,...
etc..

I have a scenario where...
1.) Have created a div with a dropdown list and ok, cancel button
2.) On document ready - registering div created on step 1 into a jQuery dialog
3.) on a javascript button click - I am opening this dialog box.
4.) Now, the problem is - the jQuery dialogbox which I have created, needs to be used by other button clicks as well on same page. Now, my div's (which is a dialog at runtime using jQuery) ok button click is already engaged with a javascript function (button1 click) and I can not associate other button's click events with it - thus stuck up here and have no clues or hit to resolve this.

I am building a web site with visual web developer 2010
I have a class (autoButton) that adds a button to a panel (on Default.aspx) and a handler w/i the same class (classifyEventHandler)
The button appears fine, but when clicked the even doesnt fire, what am I doing wrong?
I tried locating the event handler in default.aspx, but it was not found :P
Imports Microsoft.VisualBasic
Public Class autoButton
Public Sub makeClassifyButton(ByVal theCell As Object)
Dim myButton As New Button
myButton.Text = "classify"
myButton.ID = "b_classify_" + theCell.ID
AddHandler myButton.Click, AddressOf classifyEventHandler
theCell.Controls.Add(myButton)
End Sub
Private Sub classifyEventHandler(ByVal sender As Object, ByVal e As EventArgs)
MsgBox("done?!")
End Sub
End Class
