Javascript - Looking For Charts Library That Supports Linked Events?
Nov 16, 2010
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.

Just I started learning MVC pattern, of course i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there)
1 ) MVC does not support server side events, but supports client side events. If it supports client side events, I need html page with jQuery/Javascript (view), but most of the example I absorbed is to display the information(model) in view, I did not see any client side event handling happens in view.
2) Except ViewState and controlState, MVC supports Sessions, Application State management, Cache management.
3) When request goes to MVC engine, the routing module routes the request that is picked up by the controller. The controller in executes the appropriate action and returns the appropriate view.

Google Page Speed is saying we should combine external JavaScript. Fair enough.
I know that the way to do this is to use a CompositeScript tag inside asp:ScriptManager.
<asp:ScriptManager runat="server">
<CompositeScript>
<Scripts>
<asp:ScriptReference Name="AjaxControlToolkit.Common.Common.js" Assembly="AjaxControlToolkit" />
<asp:ScriptReference Name="AjaxControlToolkit.Calendar.CalendarBehavior.js" Assembly="AjaxControlToolkit" />
< ... />
</Scripts>
</CompositeScript>
</asp:ScriptManager>
What I don't know is which script references to add. In my page I have lots of <script src="/ScriptResource.axd?d=big-string-here" type="text/javascript"></script>
How do I discover what <asp:ScriptReference Name="x" Assembly="Y" /> tags I should add to the CompositeScript tag? There's a usercontrol out there with this specific aim, and we even have already used it before, but I can't find it again o Google.
EDIT
The usercontrol I was looking for is ScriptReferenceProfiler. How to use it.

I love the demos of ASTreeView. I'd like to use this in my project, which is completely local and currently only uses HTML, JavaScript, and CSS - i.e. no ASP.net or anything dealing with servers...
Is it possible for me to use this? There is a .dll and a .js included in the package, but I have no clue where to start since this isn't a ASP.net project for me. I can't find any documentation on this library.

I have an ASP.NET application using a master page. I am adding a reference to the JQuery library in the master page however there are some content pages and user controls that reference the JQuery library directly. Will I need to remove each reference from those pages or can I leave them in place even though I am adding a reference into the master page of the application?

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 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>

What is the best library/software to compress the dynamically generated javascript on server? I use javascriptzip to do so statically. Any solution for .Net platform? P.S. compression involves removing unnecessary spaces + language compression like changing new Object() into { }

I have a javascript library and in there i have a method that is called from my view. Here it is:
<li><a href="javascript:void 0" onclick="deleteAll('image', '<%= ViewData["FileGroupId"]%>')"><div><%=GetGlobalResourceObject("default", "Delete_all") %></div><div></div></a></li>
and here is my js code in the javascript library:
var deleteAll = function(module, groupId) {
jConfirm(_deleteConfirmAll, _deleteAll, function(r) {
if (r) {
showProgress();
$.ajax({
cache: false,
type: "POST",
url: _baseUrl + "/" + module + "/deleteall/" + groupId,
success: function(msg) {
if (msg == '0') {
location.href = _baseUrl + '/' + module;
}
else {
jAlert(msg, _errorTitle);
}
hideProgress();
}
});
}
});
}
My problem is that i cant reach my controller. Here is my controller code:
#region common methods
List<.CMS.Core.File> GetList(int groupId)
{
List<CMS.Core.File> list = new List<CMS.Core.File>();
CMS.Core.FileFilter filter = new CMS.Core.FileFilter();
filter.GroupId = groupId;
int res = CMS.Core.File.Search(_connection, filter, ref list);
return list;
}
#endregion
public ActionResult DeleteAll(int groupId)
{
List<CMS.Core.File> list = GetList(groupId);
foreach (File item in list)
{
item.Delete();
}
return Json(list);
}
And at last her is my Index method
public ActionResult Index(int? id)
{
if (Request.IsAjaxRequest())
{
JsonPaging paging = new JsonPaging();
int offset = 0;
int page = 0;
if (!String.IsNullOrEmpty(Request.QueryString["page"]))
{
Int32.TryParse(Request.QueryString["page"], out page);
}
if (page > 0)
{
offset = (page * paging.PageSize) - paging.PageSize;
}
FileFilter filter = new FileFilter();
filter.Deleted = false;
filter.MaxRecords = paging.PageSize;
filter.Offset = offset;
if (!String.IsNullOrEmpty(Request.QueryString["keywords"]))
{
filter.FilterType = FilterTypes.AND;
filter.Name = Request.QueryString["keywords"].ToString();
}
if (!String.IsNullOrEmpty(Request.QueryString["sort"]))
{
filter.OrderBy = Request.QueryString["sort"].ToString();
if (!String.IsNullOrEmpty(Request.QueryString["direction"]))
{
filter.OrderBy = filter.OrderBy + " " + Request.QueryString["direction"].ToString();
}
}
if (id > 0)
{
filter.GroupId = id.Value;
}
List<CMS.Core.File> items = new List<CMS.Core.File>();
int results = CMS.Core.File.Search(_connection, filter, ref items);
foreach (CMS.Core.File current in items)
{
JsonItem item = new JsonItem();
item.Id = current.Id;
item.Name = current.Name;
item.ImageText = current.ImageText;
item.Aperture = current.Aperture;
item.TakenOn = current.TakenOn;
item.Camera = current.Camera;
item.ExposureTime = current.ExposureTime;
item.FocalLenght = current.FocalLenght;
item.Tags = current.Tags;
item.Url = current.Url;
item["Active"] = current.Active.ToString();
item["Created"] = current.Created.ToString();
paging.Items.Add(item);
}
return Json(paging, JsonRequestBehavior.AllowGet);
}
else
{
ViewData["FileGroupId"] = id;
return View();
}
}

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 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 have several web sites, all of which use the same JavaScript library. How can I "reference" this library from each of my web sites? If I just import the library into my web site in Visual Studio, I get in trouble as soon as the library changes, because I then have to update it in all web sites manually. It would be much easier to place the library in an external folder and just reference it from my web sites. How can I do this with Visual Studio?

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 looking at the twitter api page http://apiwiki.twitter.com/ and I noticed that they have already built libraries that are wrappers against the twitter api. So I am thinking this is the best way to go but I am unsure which C# library I should use.
What I am trying to do is make some simple service or cmd line application that will help me automate retweeting.
So I am looking for a library that will allow me to get posts from other twitter accounts and then retweet them from another account.
I am not sure if the library can do this or not. Otherwise I was thinking of getting the RSS feed from the twiter account I want to get the twitters from parse out the new ones and use a library to retweet them on my own account.
I have not used twitter much so I am hopping someone can shed some light on this.

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.
