Timing Of Page_load And Javascript Onload
Dec 19, 2010I have the following call in my master page
[Code]....
So, in the above on the Master Page onload I am calling the javascript to get the screen resolution Then in my default page....which is being used first. My master page is loading and then my default page is loading. I have this is my Page Load event
[Code]....
However, what is happening is that I am getting the MessageBox.Show from the default page saying the screen is <null> by <null> and then I start getting the alert boxes from the javascript saying what the screen width and screen height is. In my page Load event of default. how can I wait until the java script in Master is done? Or is the a better place to put these events?

Javascript To Run After OnLoad But Before Anything Else To Set Defaults
Sep 7, 2010So I have an .aspx page loading up and populating drop downs based on a lookup table in the database. What we want is for the user to be able to configure which of these values comes defaulted by specifying that value in a drop down somewhere else in the app. Now, it's easy to default the "first" value, or something like that, but we want this to act differently. Is there a JavaScript function that can run immediately after onLoad (so the drop downs are populated already), that can go through the drop down and make one of those default so it looks like the page is loading with that set as default and people don't realize the workaround? (weird masking, etc.) I'm not TOO experienced with JavaScript so something like this may already exist. Here is an example of how we add the dropdown control to the page, in case you guys even need that.
With CType(.AddControl(New Controls.ComboBox("CodeId", "../../../../CodeId", "Code")), Controls.ComboBox)
.ForceSelection = True
.ValueField = "LookupID"
.DisplayField = "LookupDesc"
.Validate.AllowBlank = False
.ForceSelection = True
.ReadOnly = EditControl.IsFieldReadOnly(10580)
.BindData(Model.Codes)
End With

Web Forms :: MasterPage Onload Fires Twice?
Jan 20, 2011I have abit of a problem, with the AutoEventWireup setting.
Currently, my master page's onload seems to fire twice. If i set wireup to false, it doesn't fire at all.
All my page, using the masterpage, also has the setting set to true.
Should i only have it set to true in the master?
What happens to my events in the indidual pages then? Does the masterpage handle the wireup, if they are set to false, and it is set to true?

Dynamic Adding Controls During OnLoad Or OnInit?
Sep 17, 2010I want to add more controls to page based on some specific conditions. Those controls don't need any ViewState or binding data, it is as simple as a static link. I wonder where I could write the code: inside OnLoad or OnInit method? and why? If I place it inside OnLoad, should I add following line: if (IsPostBack) return; before any initialization code?

OnLoad Method Where Some Conditions Are True After Refresh/redirect?
Jul 27, 2010HttpContext.Current.Response.Redirect("~/Examples/my.aspx");
//or

the code above generates the error as I mentioned at this topic's title. I simply need to refresh my ASP.NET page, I can't use that code instead:HttpContext.Current.Response.AddHeader("Refresh","2");because it says about IIS pipeline modeThe puprose is that I must get into OnLoad method where some conditions are true after refresh/redirect

Page OnLoad Not Fireing Changing Query String?
Dec 2, 2010I have a problem that the OnLoad event is not fireing when I navigate to a page and just change the query string. If I do a postback it is called, then changing the query string ones more OnLoad gets called.
Here is how i try. I navigate to the page OnLoad fires -> then change the query string page updates (all bound elements get updated) OnLoad does not fire -> I do a postback using a button OnLoad fires -> then change the query string OnLoad fires. I will try to explain in more detail.
The system has log in window when I log in I navigate to an other aspx page sending two query string messages the last query string is a number (page.aspx?key=text82&key2=2010). When I get to the page the first time PageLoad event gets called and all is fine, if I in the browser change the key2 to 2011 and press enter the PageLoad does not get called but all my bound elements get updated (GrivView etc..). If I then do a postback using a button the PageLoad gets called. If I now change the 2011 back to 2010 and press Enter PageLoad is called. I try this is firefox the PageLoad get called every time. I tired to write a test website but I do not get the same problem, but what i found out is that in IE 8 changing the query string to the same number and pressing enter the PageLoad is not called. But doing so in firefox makes the postback fire. Here is the test code

C# - Javascript Event Like Window.onload For Subsequent Loads?
Feb 9, 2011We have a function that changes the iframe height at the window.onload event so we can adjust it to the page contents. The problem is that after clicking in an asp:menu the height its restored to its default and the window.onload event doesnt fire...so we need the event that would fire in subsequent loads (tried window.unload but didnt trigger)
The resize function cant be called on the asp:menu click because the window wouldnt have finished loading so the height calculation would fail...
How To Capture The Onload Event Of A Window With Attachment Response
Jan 26, 2010I have the following download request in javascript:
var exportWindow = window.open('Download.ashx?source=1', '');
exportWindow.onload = function() {
alert('finished');
};
My problem is that the above alert box does not appear. The download.ashx sets up the following response (which will be saved as a csv file), which works fine.
context.Response.ClearContent();
context.Response.ContentType = "application/text";
context.Response.AddHeader("content-disposition", "attachment; filename="" + fileName + """);
context.Response.Write(resultWriter.ToString());
context.Response.Flush();
context.Response.Close();
If I replace the download.ashx with a normal aspx page, then the alert appears. So my question would be: is it possible to know programatically when the dowload.ashx returned with a response?(using FF3)
Use OnLoad Event To Check If There Is A Cache File For This Module?
Dec 27, 2010We are writing a portal and like every portal we store html data in Db fro Modules. So I thought that I can cache each module in files. I use OnLoad event to check if there is a cache file for this Module, use that and else create cache file:
if (!IsPostBack)
{
string Path = AppDomain.CurrentDomain.BaseDirectory + "CacheModules" + ModuleId + ".dat";
if (File.Exists(Path))
{

Override The OnLoad Of The Class That The .aspx Is Directly Inheriting From?
Jan 19, 2010If I'm writing in-line code on a .aspx page is it possible to override the onLoad of the class that the .aspx is directly inheriting from? Right now if I do the override the base.onLoad inline on the .aspx page it is overriding the "Page" object's onLoad event not the class the .aspx is inheriting from.
View 1 RepliesAJAX :: CollapsiblePanelExtender Onload When Using Master/Content Pages?
Oct 4, 2010I'm wondering if anyone else has run into this problem; I have a collapsible panel extender to which I need to add some event handlers via javascript on page load:
$find("behavioridhere").add_expandComplete(expandHandler);
This was working perfectly...*until* I split the page into the Master/Content page scenario. The control, the scriptmanager and the javascript are all declared in the content page right now. Suddenly, all my client side code comes up as the object being null or not found at the window.onload event. After 3 days of chasing this dragon, I added a test button which calls the same functionality which should run onload and when clicked, it has no trouble at all finding the object *after* the page has fully loaded. I've looked into almost all the posts on the web about this and I've found the question...but not the answer. I've played with the recommended fixes dealing with BehaviorID...the ClientID...the ctl100_control_object and ctl100$control$object names and I'm still dead in the water.Somehow, I have to get this code to run at the page onLoad event.
Javascript Error - This.node.onload=function() Is Null Or Not An Object
Oct 27, 2010I am working on ASP.NET 3.5, c#, visual studio 2010. I have made a master file and a default page that uses this master file. I have placed a couple asp:contentplaceholders in the master and corresponding code in the page that uses this master. I have also inserted JavaScript like this in the content page (and not the master):
<asp:Content ID="Content6" ContentPlaceHolderID="Mainpage" Runat="Server">
<script src="path1" type="text/javascript"></script>
<script src="path2" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
var options = {
//some java code
};
$(".mycssclass").effect(options);
});
</script>
</asp:Content>
On running the website I get the following runtime error in visual studio: Microsoft JScript runtime error: 'this.node' is null or not an object and it point to some function inside the JavaScript like this.node.onload=function(){..............//I am not a java guy so do not know much about this Where am I going wrong? Why does the site compile correctly but throw this runtime error? I also tried inserting this java code inside the master file in the <head>, but same error.
Adding / Removing Session Variables On Page OnInit/OnLoad In C#?
Jan 16, 2011I am using C#.
I am having below code in C#:
protected override void OnInit(EventArgs e)
{
try
{
if (Session["boolSignOn"].ToString() == "true".ToString())
{
lblPanelOpen.Text = Session["panelOpen"].ToString();
}
else
{
lblPanelOpen.Text = Session["panelOpen"].ToString();
}
}
catch (Exception ex)
{
Logger.Error("Error processing request:" + ex.Message);
}
}
protected override void OnLoad(EventArgs e)
{
try
{
if (!string.IsNullOrEmpty(Session["panelOpen"].ToString()))
{
lblPanelOpen.Text = string.Empty;
Session.Remove("panelOpen");
}
}
catch (Exception ex)
{
Logger.Error("Unable to remove the session variable:" + ex.Message);
}
}
In above code I am having a Session["panelOpen"] variable which is created from another user control and once my page is trying to render, I am storing Session["panelOpen"] in my hidden lblPanelOpen.Text on page OnInit() method, however when page is loaded completely then I am trying to remove the session variable.
