Difference Between Adding Code In The PreLoad Event Handler And At The Top Of The Load Event Handler?

Oct 3, 2010

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?

Web Forms :: Adding Event Handler To DropDown List In A GridView?

Feb 26, 2010

I have a GridView control that contians, among other things, a DropDownList. In this particular case, the DropDownList is in the EmptyDataTemplate, but I suspect I will run into a similar situation when I'm in Data Rows as well.I'm trying to handle the OnSelectedIndexChanged event for the DropDownList and in the .aspx file I have used the declarative syntax to assign the handler OnSelectedIndexChanged="ddlStoreList_SelectedIndexChanged") and have created the handler code to deal with this.

[Code]....

The problem that I'm running into is that the event is not being handled. In other words, when I put a breakpoint in the handler, I find that it is not getting hit when I change the selection of the DropDownList.

Web Forms :: Load A User Control On Link Click Event Of A Link Button During Postback Of Aspx Page?

Mar 2, 2011

Here is my requirement -

1. I need to load a user control on link click event of a link button during postback of aspx page.

2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.

If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.

Web Forms :: Programmatically Created Event Handler For A Button Doesn't Fire Up?

Mar 21, 2010

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:

Forms Data Controls :: Datalist Button Not Firing Event Handler?

May 10, 2010

I put it down for a few weeks to work on other things, but started working on it again because I need to get it to work.

Anyway, I figured if I wanted to put a button in a datalist all I had to do was:

[Code]....

And then in code behind:

protected void datalist1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "submit")
{
// code here
}
}

This is what everyone else says to do when I search google. I put a break on the event but the event never fires. Does it matter if I am using VS 2010 and .net 4.0?

Button Click Event Handler Before Page Load?

Jan 12, 2011

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?

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"

VS 2008 - Event Handler For Dynamically Created Button

Jul 31, 2013

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);
