I 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?
I am trying to get value of a variable"offset" code behind of content page which is set from default.aspx through onload event from master page.But it gives null value every time. Here is my code.

<head>
<asp:ContentPlaceHolder runat="server" id="Headers"> [code]....
I have a MasterPage (MasterPage.master) with 2 child MasterPages (specialMaster.master and standardMaster.master). From the MasterPage.master I need to get at some of the controls in one of the children, specialMaster.master, say for example to hide certain
content if a session variable is not null.
I have 2 masterpages. (Default.master and User.master).I have a hidden field in Default.master then how can i get the hidden field value of Default.master file from User.master.is there any way to access that hidden field like: Request.form("hidID") ?

So 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

I 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?
I'm working on custom web control, inherited form label control. Try to run some JavaScript in page load event. But not working! Or any equivalent onload event for label control?

I am using a RegularExpressionValidator in my code as follows:
<asp:RegularExpressionValidator ID="rev1" runat="server"
ValidationExpression="[a-zA-Z0-9]{5,7}"
ControlToValidate="txtTAM5" ErrorMessage="Please enter a valid value." SetFocusOnError="True"
Display="Dynamic" ValidationGroup="vg1"></asp:RegularExpressionValidator>
I 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?

View 3 RepliesI have one RadionButton and a Button.
When I clik on RadionButton it fires it CheckedChanged Function perfectly.
But, when I click on the Button, it ALSO fires the same RadionButton ChechedChanged Function! I don't know why!!!
I want to avoid that! I don't want the button firing that RadioButton function.
When I start debugging my application using vs2010 before the default.aspx page is rendered the application_error event is fired in global.asax.
There is nothing happening in the page_load of the default.aspx screen.However, if I set a break point on the default.aspx page_load event and the application_error event here are the sequence of events: The page_load event of default.aspx is fired, there is no code to execute there so I hit F5 to continue. The application_error event is then fired.Here are some of the details from Server.GetLastError();
exception message is "File does not exist."
stack trace:
at System.Web.StaticFileHandler.GetFileInfo(String virtualPathWithPathInfo, String physicalPath, HttpResponse response)
at System.Web.StaticFileHandler.ProcessRequestInternal(HttpContext context, String overrideVirtualPath)
[code]...
I have absolutely no idea why this event is fired. Do all of the events in the Global.asax get fired on startup?There is nothing happening on the page_load so how can an error be thrown?
I have this form to update a users details. This really should work but doesn't seem to want to update the email, isApproved etc. The onload data is within "If not ispostback". I can't see why this won't work. It is attached to an update button btw.

View 3 RepliesI have this javascript
function myFunction(source) {
window.open(source, "Title", 'width=400, height=400');
}
and in c# code I call it by
HtmlPage.Window.Invoke("myFunction", source);
which opens up a aspx page and goes to its OnLoad function:
protected override void OnLoad(System.EventArgs e)
{
base.OnLoad(e);
how do I pass in parameters to the event args in the aspx page? or is that even possible? and how can I pass these parameters from my c# code to the javascript?
