Need help with Javascript in a separate .JS file


I have searched hundreds of posts over countless forums, but am unable to run a Javascript that is placed in a separate .js file. If the script is placed directly in the <HTML>, the script runs fine.


I have simplied the example down to an .aspx page with a single button and the codebehind in VB. I am currently running VWD 2010 on the .Net 4 framework. I've been working on this problem on and off over the past 3 weeks and simply cannot get it to work, so I continue to insert the code directly into the markup. I have tried countless changes to the following code, but not once able to get it to work.

Any help, suggestions or recommendations will be graciously accepted and very much appreciated.


The .aspx page is as follows:


<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Test_Script.aspx.vb" Inherits="Test_Script" %>


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

C# data bound combobox: display selected item text in separate label.content


I am new to C# but I'm resisting the urge to run screaming back to VB.NET. I'm working with a WPF application using C# code-behind and a lot of binding to a SQL 2005 database backend.

GOAL: I have a comboBox bound to a tbl_Systems entity which provides a list of systems for user selection. When the User selects a system from the comboBox I want to display the selection's text in a separate Label. The big picture is that several comboBox selections will be used to build a query string that will populate a listbox. So, I want to display these selected values in the Label so the user can see the query string they have dictated.

PROBLEM: When I set the Label content property to the comboBox SelectedItem property the entity tbl_System is displayed in the Label not the comboBox selection text.

SUSPICION: From reading similar examples in VB I suspect that the comboBox SelectedItem is actually a "datarowview" or the C# equivalent. But I don't know how to translate this explanation to C#.

The UI XAML comboBox properties are set as such:


how can i return selected item from comboBox in separate thread ?

How to keep the hover for Parent menu and set the selected menu item css for child menu item?



I'm using cssfriendly control adapter for menu. My asp.net menu control's datasource is a sitemap file I'm using which contains all the urls.

  2. Is there a way to keep the child menu item selected? I am able to set the css for the parent menu, however I was wondering if the same is possible with the child items.

Please help! Smile

ASP.NET 4.0 Menu Top Level selected item style


I want to apply a css class to the level 1 menu item (parent) when it or any or it's children are selected.

I've looked at MSDN documentation and any number of examples and walkthroughs but I haven't come up with a way of managing this. I was thinking something like this might work but the style is not being applied to the parent. To further complicate matters, if I try to apply a css style to StaticSelectedStyle it doesn't pick it up at all.

Menu Markup:

<StaticSelectedStyle  Font-Bold="True" ForeColor="#3333CC" />

Code Behind:

        protected void MenuItemClick_NavMenu(Object sender, MenuEventArgs e)


            MenuItem parentItem = e.Item.Parent;

            if (parentItem != null)


                parentItem.Selected = true;

' Font-Names="Verdana" Font-Size="8pt" Onkeyup= "keyUp(event.keyCode)" Onkeydown="return isAlphaNumeric(event.keyCode);" onpaste="return false;">

Button to copy selected item in dropdown to textbox

Hi, I found this bit of code which I tried and it isn't working. I just want to place a button next to a dropdown, and when clicked, the selected item in the dropdown will put into another textbox. <head><title>Untitled</title></head><body><script type="text/javascript">function copy() {var sel = document.getElementById("names");var text = sel.options.value;var out = document.getElementById("output");out.value += text+"\n";}</script> <select id="names"><option>Product One</option><option>Product Two</option><option>Product Three</option><option>Product Four</option></select><input type="button" onclick="copy()" value="Copy"><textarea id="output"></textarea> </body></html>   I saved this as a file and opened it in IE to test and nothing went into the textarea. Also i tried it in Firefox and the textarea said undefined each time I click the button. Can someone help to get this working?
