I have the following Master Page
[Code]....
Which is used in the following Page
[Code]....
With the following code behind
[Code]....
The trouble is while the event handler for the btnSearch fires, the same can not be said for the btnSave handler.
Anyone see what obvious thing I have missed.
I put a break point at the protected void Page_Load(object sender, EventArgs e) method of my master page, but when i start the site it does not hit that break point.
Why is the event not firing? I would like to use this event along with others such as the Init event in order to check to see if the session has expired everytime a page loads...
I'm using SelectedIndexChanged on a gridview row to trigger an event which is working fine in a normal webform. But, when I included "master page", it's not triggering the same event.
everything is same except, I added MasterPageFile location & removed FORM tag.
ASP code
<%@ page title="" language="C" masterpagefile="~/site.master codebehind="test.aspx.cs" inherits="Main.test" enableEventValidation="false"
autoeventwireup="true"%>
<asp:content ID="content1" contentplaceholderid="headcontent" runat="server">
<link href="styles/CS1.css" rel="stylesheet" type="text/css"/>
<asp:content/>
<asp:content ID="content2" contentplaceholderid="maincontent" runat="server">

When master page event fires, content page events are fired first,
is there any content page event that fires after the master page events.
I have a master page with a login box on it. Inside the login box is a button -
[Code]....
NOW ... On my local dev machine this code works fine. The control fires the event and everything is how it should be. When I run this site on a remote web server (tried two of them - both IIS7 running on 2008 R2) the event is never called. I added some logging to see what is happening and the PostBack event on the Master Page does not happen when the button is clicked - the page is just reloaded.
I have a fairly complex web app which has two levels of master page. The top level provides a nav bar constructed from a Menu control across the top of the page. Second level master pages provide menus down the side. It all works well.
On both Menu controls, I need to handle the MenuItemClick event. This works fine on the Menu controls on the second-level master pages. However, the Menu on the top level master does not raise the event at all.
This web site makes extensive use of Ajax and the top-level master page contains the ScriptManager. Before I go to all the work of creating a much simpler test site, why the Menu control is not raising the MenuItemClick event?
Here is the markup for the Menu in the top-level master:
[Code]....
Here is the MenuItemClick event handler:
[Code]....
The logging call in the event handler never gets called. Equivalent code in the Menu on the second-level master does get called.
am using a master page, with children pages.
I am using forms authentication, and a session object to hold user information once the user is authenticated.
I am able to login and log out. I am able to log in and use the "remember me" functionality of the forms authentication.
When attempting to test the "remember me" functionality, the master page load event contains code to check the forms authentication & remember me, and retrieve user info from the database to automatically log the user in. This fires correctly, and the screens all load with the user successfuly logged in, and the users info is successfully stored in a session object.
Without touching anything on the screen, a moment passes and then the master page load event spontaneously fires again, Page.User.Identity.Name still contains the user name, however the session variable is now null, and throws an error.If I tell it to run past this error, it does, and the application continues to function normally, withthe session variables set correctly.
Its almost as if that second firing is ina different session, or something.
I have no problem posting code, but I have a profile class holding / handling the session communication, etc so it is a bit cumbersome.
this is my radio button list:

this is the code behind:

I have a custom class (ServerSideValidator.vb) that validates user input on server side (it doesn't use any of the .NET built in validators, therefore Page.Validate() is not an option for me). I am calling the Validate() method on page.IsPostback event and the class performs without any problem
My issue is, when validation fails (returns false), I want to stop the postback event handler from firing, but load the page along with all the controls and user-input values in them. If I do, Response.End(), the page comes up blank. I can programmatically instruct the page to go to the previous page (original form before postback), but it loses all user-inputs.
I thought of creating a global boolean variable in the page code behind file and check the value before performing any postback method, but this approach takes away from my plan to provide all functionalities inside the class itself. The page object is being referenced to ServerSideValidator.
Seems like all the postback related properties/variables I come across inside Page class are 'Readonly' and I can't assign value(s) to control/prevent postback event from firing.
I have a control which has an ImageButton which is tied to an OnClick event... Upon clicking this control, a postback is performed and the event handler is not called. AutoEventWireup is set to true, and I've double checked spelling etc.... We haven't touched this control in over a year and it has been working fine until a couple of weeks ago.
We have made changes to controls which load this control... so I'm wondering, what kind of changes could we have made to stop this event handler from being called? There is quite a bit of Javascript going on, so this could be the culprit too...
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?
I am trying to create a custom GridView with a header toolbar at the top that will contain icons to export the grid view to different formats like excel, word, etc.. The problem is, I cannot get the method to fire that is assigned to handle the click event for the corresponding Image Button. The page posts back, but the code I have in the method to handle the click event does not fire. I have followed examples in other posts and from what I can tell I have followed what others have done. Can somebody take a look at see if they can find something that I am doing wrong.

I have a web application that shows a page containing between 6 and 20 UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here: [URL]
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)

I have to masterpages for my home page.
1. The first is for the annonymous users which has the login controls. its name is General_Anonymous.master.
2. The second one is for the logged in users which has a logout button and it hasn't the login controls in it. its name is General_LoggedIn.master. in my default.aspx page I wrote the following code
protected void Page_PreInit(object sender, EventArgs e)
{
if (Session["SupId"] == null && Session["CustomerId"] == null)
{
this.MasterPageFile = "~/Masters/General_Anonymous.master";
}
else
{
this.MasterPageFile = "~/Masters/General_LoggedIn.master";
}
}
after the user logs in my website he is redirected to his home page. If he want to return to the home page he uses the home hyperlink which refer to the default.aspx. I think according to my code that when the user comes from his home page he will bring his session with him and when the default.aspx asks for the session value it found the id of whether a customer or supplier and thus it will use the second master page General_LoggedIn.master But my problem is when the user click homepage link the default.aspx uses the 2 masterpages . which means I find the logout button and the login controls . I don't know what is the problem or the error in my code
I am also facing some issues with Back Button of Internet Browser as well. Actully Page Load event of my page is not firing when i click on Back Button of Internet.
View 1 Repliesi hv a gridview in modal popup,I hv taken checkboxes in itemtemplate and written code in javascript function to checked or uncheck the checkboxes.and in pageindexchanged event calling that javascript function to maintain the state of checkboxes.it is working fine.but when i put it inside update panel nothing is happening.
View 1 Repliesi want to give id of dropdowncontrol inside master page, how can i assign this control id in trigger of updatepanel inside content page
View 1 RepliesIs 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 have a page books.aspx that has a control named authors.ascx.
Inside the authors control there is a "select" button I want to add some kind of listener or event handler (not sure of the correct terminology) so on the parent page (books.aspx) I can respond to the "select" button being clicked.
I have to pass the authorID from the user control to the parent page.
In my authors.ascx control I just created this event:
[Code]....
Now I need to write the function for SelectAuthorBtnClick and I think add some kind of listener in the parent page to listen and handle the event.
I have a Silverlight control on page which has a upload control. the silverlight exposes some events such as
StartUpload() => To start the file upload,
StopUpload() => To stop the file upload if running,
CheckFileStatus() => to check the status of the file upload.
The page has aspx Submit button with onclientclick event and ocClick event.
<asp:Button ID="btn_upload" Text="External Upload" runat="server" OnClientClick="Javascript:StartUpload();"
OnClick="btn_upload_Click" />
When I click on the aspx Submit Button, the file selected in Silverlight control should be uploaded and after the completion of upload, the Server side event should get called.
I am feeling that I have terribly wrong somewhere. I was working on a small asp.net app. I have some dynamic themes in the heme folder and have implemented a page base class to load the master page on the fly. The master is having the ContentPlaceHolder like: <asp:ContentPlaceHolder ID="cphBody" runat="server" />
Now I am adding pages that are derived from my base class and added the form elements. I know, Visual Studio has problem showing the page in the design mode. I have a dropdown box and wish to add the event of onselectedindexchange. But it is not working. the page is like this:
<%@ Page Language="C#" AutoEventWireup="true" Inherits="trigon.web.Pages.MIS.JobStatus" Title="Job Status" AspCompat="true" CodeBehind="JobStatus.aspx.cs" %>
<asp:Content ID="Content1" ContentPlaceHolderID="cphBody" runat="Server">
<div id="divError" runat="server" />
<asp:DropDownList runat="server" id="jobType" onselectedindexchange="On_jobTypeSelection_Change"></asp:DropDownList>
</asp:Content>
I have also tried adding the event on the code behind like:
protected void Page_Load(object sender, EventArgs e)
{
jobType.SelectedIndexChanged += new System.EventHandler(this.On_jobTypeSelection_Change);
if (!IsPostBack)
{
JobStatus_DA da = new JobStatus_DA();
jobType.DataSource = da.getJobTypes();
jobType.DataBind();
}
}
protected void On_jobTypeSelection_Change(Object sender, EventArgs e)
{
//do something here
}
When does an event of a master page fire? What is the order of firing events between Master page and Content page in asp.net?
View 1 RepliesI am wondering how to add a javascript event handler using asp.net ajax. I need to add event handlers after ajax update because Jquery plugin to sort tables doesn't work and the onload method to display a screen keyboard does not trigger as well. Is there a way to do that? Maybe I need to switch to some other ajax library or/and try Asp.Net MVC to accomplish?
View 1 RepliesSimple question here, but I've got a nagging feeling that there's a more interesting solution than the one I've chosen:
Page Two consists of a dropdown, and the change event is handled to execute some query.
protected void ddlSavedQueries_SelectedIndexChanged(object sender, EventArgs e)
{
/* stuff happens */
}
Page One is a home page, where I'm providing another version of that dropdown. I'd like the change event in this case to redirect control to Page Two, and then execute the event handler.
My cheap solution is just a Redirect with a querystring value that is handled on page load.
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.
