Binding Javascript Keypress Events?
Nov 22, 2010
I have a need to monitor the state of the Shift key, whether it is up or down. Its purpose is to notify the user that while the shift key is held down, the drag and drop operation they are about to perform is going to COPY the node(s), and not move them.
I have it working perfectly with the code below, however, if I hold the Shift key and perform the drag and drop, the hook no longer exists; the screen no longer responds to the key press and remains in the "pressed" state.
<form id="form1" runat="server">
<div>
<table>
<tr>
<td valign="top"><ASP:Literal id="treeLeft" EnableViewState="false" runat="server" /></td>
[Code]....

how to execute the code behind function using JavaScript keypress ?
The reason is that the keypress that I'm referring to will be used in searching record so I want that every keypress a result will be shown in the gridview immediately.

I have an ASP page which displays a text box when it loads. It takes an input number, send it to the server through post back, and then displays some record in a grid view. After a number is input into the box, the server fetches some data from a database and add records to the grid view. It also contains a link column, whose URL is set to "#", so that the page isn't redirected when it is clicked.
Now I want to bind a jquery "click" event to that link. How can I do that ? I have tried that to do myself but failed, because it is not available when the DOM is loaded (since it only contains rows when a number is input through the box), and is being modified through ASP.NET Ajax post back.

I'm using a .js file to bind events to controls. I'm also using UpdatePanel to do async postbacks; however, when they postback,the controls lose the events that were initially bound to them. Is it possible to rebind the events in the Page_Load function by using the .js file?

I've been searching a little bit to try and find the answer to this problem. As of right now another person I work with has designed a wizard step with an upload button in part of it. After the person clicks the browse button and selects their file a validation statement comes up saying, "Please click 'upload and continue' or clear the field" and then is supposed to disable the continue button until this is done. He started by adding a RegularExpressionValidator and found it did not solve his problem.
Now that he's out today we're working on trying to solve this and my first though is to actually use a custom validator instead and have it call a function in the back-code for validation which checks to see if the "Upload" click-event has happened. Is there an easy way of verifying whether or not a click-event has occurred. Basically my conditional is shown in the pseudo-code below...

I noticed that the asp:Button for example will work without javascript enabled in the browser. However any other control with an "OnClick" or "OnServerClick" event must use the javascript_doPostback.Are there any controls besides the Button that don't need to use javascript?I want to know because I want to be able to style the Control however I want without it looking like a button, and I want it to still work without the user having javascript enabled.

I am creating a ASP.Net server control to manage locations. The control is a composite control containing several text-boxes, labels, and a link button. I use the AJAX Control Toolkit to provide a modal popup which contains a Bing map. All the Javascript is in its own file and used as an embedded web resource.
The link button is what opens the modal popup. It also needs to call a Javascript function that initializes the Bing map (onclick = "GetMap();"). There are instances when this server control is placed within an Update Panel (and there is no way to avoid this). When in an Update Panel the link button loses its onclick event. I understand that this is because during an async postback the portion of the DOM that defines the content of the Update Panel is thrown out and reinitialized, resulting in the event breaking. When the control is not in an Update Panel everything works as intended.
I have tried registering events on Page.Load and Page.Init, like so:
[Code]....
I have also tried flat out writing the function call to the page:
[Code]....
I have put breakpoints on the lines inside each delegate and they do not get hit. I am not aware of any special way to register events of a composite control's child control or the Page.Load/Page.Init events when being done inside a server control. Is there some special way to register these events? (Note: Both those code blocks above are in my CreateChildControls() method)
Below is the GetMap() Javascript function. As you can see it is pretty straight forward.

I am looking for a Library that allows me to create Charts like the "Annotated Time Lines" that are e.g. used on Google Finance. I can't use the Google API because it relies on Flash and my chart should not only work on all common browsers but also be usable with mobile devices like the ipad. I don't need all of the features of Google's Solution, but displaying linked event flags in the chart is an essential requirement and the ability to arbitrarily zoom and pan the chart would also be nice, the latter feature is however not a must on mobile devices and older browsers.
A serverside solution that transparently generates plain image charts if flash (or other client features like canvas-elements) is not available on the client would also be ok, I have asp.net mvc 2 running on the serverside.
An open source solution would be great, but a commercial library or component is also an option.

I have a user control in an asp.net web application. The control outputs an html list that is customized based on the currently logged in user. The list items are generated from a database look up and the user control is formatted to appear as a drop down list in the page.
The control itself is simple and looks like this:
<%@ Control Language="VB" AutoEventWireup="false" CodeFile="item-lector.ascx.vb" Inherits="includes_usercontrols_item_selector" %>
<!--Item Selector-->
<div id="item-selector">
<%=Me.Output%>
</div>
The code behind file dynamically fills the control's "output" property so the final markup appears as follows:
<div id="item-selector">
<h1>Item 1 - Item 1</h1>
<a href="#" class="changeItem itemArrow">Change item</a>
<ul id="changeItemMenu" class="dropDownMenu">
<li><a href="#">Item 1</a></li>
<li><a href="#">Item 2</a></li>
<li><a href="#">Item 3</a></li>
<li><a href="#">Item 4</a></li>
<li><a href="#">Item 5</a></li>
<li><a href="#">Item 6</a></li>
<li><a href="#">Item 7</a></li>
<li><a href="#">Item 8</a></li>
<li><a href="#">Item 9</a></li>
<li><a href="#">Item 10</a></li>
</ul>
</div>
The ID and class properties are all necessary for formatting and other scripting. The control is meant to be used as a selector and the rest of the page should react to which item the user selects.
What I am trying to do is add click events to the list items. When the user clicks on one of the items in the list, I want to capture which item the user selects in the list (does this require a postback?) and do something with it in the code behind (< this is key).
I am more of a middle tier and db tier developer and UI development is not my strength so please consider me a newbie in that regard. I am not sure how to proceed or what to inject into the output string to enable this.

I was wondering if anyone had an easy way to wire up javascript event handlers to events happening on the server-side. I have a long running process that includes a lot of steps, and would like the client to be continually updated with new information as the steps transition. Will this involve some sort of polling mechanism?

I am developing and Asp.net website. Occsionally I will have to display A Java Script dialog box. The dialog box will have two buttons on it. One labeled "Proceed" and the other labeled "Cancel". Then I need two Java Script methods to respond to which button was pressed. So I suppose my java script methods to handle the button press might look like the code below.
Anyway, I don't know how to invoke these methods when the dialog button are pressed.

I have an application that makes a series of WCF calls that return JSON via JSONP. In turn javascript code will then bind that returned data to HTML controls.
When a bot / spider hits my application, no data would be indexed because javascript would not execute in the bot.
Ideally I'd like to not have to maintain two sets of data-binding code (one on the server side and one on the client side).
Essentially I need the resulting data to come downstream. I had were to.
1) link RSS/ATOM equivalent data
2) a backdoor HTML page
3) an HTML renderer that can execute an ASPX page server side ahead of time and then pass that off to the client

I have a combobox control on my asp.net page and I have created a keypress event for it, however I am unable to wire it up when I go to my properties box. In the events in propertie there is no section listed for key stoke events?I thought that combobox controls can have keypress events.Currently when a user selects the combobox they see a list of batch numbers, they can also type in a batch number which searches the list and brings back a match. I also want the user to be able to type in a number that is not in the list and press enter, which will then bring back the results for that batch number. There is already a SelectedIndexChanged event wired up but I cannot seem to wire up a keypress event for when the user presses the 'enter' key.
