Javascript To Run After OnLoad But Before Anything Else To Set Defaults
Sep 7, 2010
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 a couple of fields on a form that will be populated with default values. I would like to put a button that will allow me to reset those fields to their default values if they have been modified. However I would like to avoid the postback so that I don't have data being sent to the database. Is it possible to add a javascript hook such that when that button is pressed I can pull the default values and populate those fields in javascript?

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 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?

In an .aspx page with the vb.net codebehind i am using IFRAME , which would be created inside the repeater control. Since i want to resize the IFRAME based on the content within the page i have been using the resize function Obtained from here on the IFRAME onload as shown below.
<iframe id="IframeSubsectionArea" scrolling="auto" width="100%" onload="resizeIframeToFitContent(this)" runat="server">
However it is throwing the error as the method could not be found in the form. Is there any client side script variant for the onload event? May i know,What might be the reason for the error and its solution?

We 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...

I 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.

I just setup an out of the box "W2K8 R2 Web" server and installed IIS 7 out of the box. Then I installed the .NET4 framework and ran "aspnet_regiis -i" command.
I created a site using .NET 4.0 Integrated app pool.
I created an MVC application using the default MVC project template, without modifying I compiled the project and deploy the files using (Publish) to the virtual directory.
I can pull the site up, but the styles are missing from the page and for some reason it routing to the /Account/LogOn?ReturnUrl=/

explain what the Dynamic Data team was thinking when they designed grid sorting in Dynamic Data scaffolded tables? Sorting defaults to using all columns, in the order the appear in the model, often arbitrary very counter-productive.We've just had a run in with the 'out-of-the-box' sorting, and solved it with a simple SortExpression attribute on MetaTables. Another, even simpler solution would have been for them to avoid any sorting, allowing the DB to provide a default order based on clustered index.

CarType
Id - PK
Name
CarDetail
Id - PK
TypeId - FK to CarType
I have this simple example here and I want to insert a new CarDetail into the database but for some reason I cannot get the EntityKey to work in EF4 and Framework4 beta 2.
If i declare the following
car_detail.CarTypeReference.EntityKey = new System.Data.EntityKey("MyDB.CarType", "Id", 1)
Each time i try to call SaveChanges, it throws a INSERT constraint error saying that there is a conflict between CarType and CarDetail with the FK. It just seems like the hard coded 1 for CarType is NOT being passed through but instead the default value of 0. What is going on?
If i call car_detail.TypeId = 1 then it works fine with the INSERT.
Why doesn't the EntityKey method work?

I have a very vexxing issue. After installing a third-party application and add-in for VSTS 2008, it has corrupted my menus/buttons by duplicating/cascading these throughout studio (i.e. Multiple sets of each menu - File, Edit, View, etc, each of which has multiple submenu entry sets). I have tried to use Add-In Manager to uninstall it and removing the application (which added the Add-in to VSTS). I tried Tools->Customize and resetting the MenuBar and ContextMenu options as well. I tried running each of the following (closing and then reopening VSTS after each) from the command prompt, which completed but did not fix things.
devenv /resetsettings
devenv /resetSkipPkgs
devenv /resetuserdata
devenv /setup
My question then, does anyone know a way to reset the menus/toolbars for VSTS 2008 to their defaults or correct this some other way? I know I can unistalll both products and resolve this but I *really* want to be able to use the third party app (Red Gate's SQL Prompt).

In my detailsview, I have an emptydatatemplate set up to allow users to enter new records. The code works. However, once the record is inserted, the detailsview defaults to a standard insert screen. I know this will cause confusion for the users. I would prefer the detailsview to either show in edit mode or a read-only mode. I have used detailsview.changemode and detailsview.currentmode in the custom sub created for the add new button of the emptydatatemplate- neither of which do what I was hoping. It would be even better if when there was no data, it defaulted to the insert screen (which seems like that should be an easy, no-brainer way for .net to function) but it doesn't. Or, I don't know how to accomplish it.
I don't want to force the user to click cancel after inserting an item through the emptydatatemplate just to be able to use the detailsview for other records.

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?
