Re: The name '###' does not exist in the current context - error

You've added a runat="server" to <div id="visualization" ...>. As a result, the client ID will not be "visualization"; it will be "ctl00$MainContent$visualization". As a result, you'll get a "container not defined" error from the Google script.

Either remove the runat="server", or add ClientIDMode="Static".

ASP

<div id="visualization" style="width: 600px; height: 400px;" runat="server" ClientIDMode="Static"></div>

hello Richard.

Thank you once again for your quick response. The code still does not work without the runat or with the clientIDMode tag. I also tired debugging the javascript but I am still unable to pin point where the code is falling.

Any advice would be most welcome.

Thank you so much.

The code works fine for me in Firefox 25, Chrome and IE10.

Hi,

Are you able to see the charts when submitting the search input? Would you mind me asking, what Visual studio you are using? I shall keep trying on my end.

Thank you so much for your help.

Kind regards

I'm using .NET 4.5.1 and a text editor. As long as you're using .NET 4.0 or higher, it shouldn't make any difference.

Are you seeing an empty chart? The String.Contains method[^] is case-sensitive, so if you type "clavs" you'll get no data back. If you want a case-insensitive search, try using the IndexOf method[^]:

[WebMethod]
public static List<Data> GetData(string name)
{
    var dataList = new List<Data>();

    ...

    return dataList.FindAll(r => r.ColumnName.IndexOf(name, StringComparison.CurrentCultureIgnoreCase) != -1);
}

Hi richard,

I really appreciate your support and time into this but for some strange reason, I am still seeing an empty chart whenever I trigger the search function on the client-side.

I changed the search code line from string to index function as you suggested, however still no result. I do not mind it being case sensitive or not. Whenever I type in "CLAVS 2007-1 M2A" into the search textbox, I am still getting a blank page. Confused | :confused:

Many Thanks

Strange - the code works fine for me. The only difference I can see is the base class for your Data class. Try removing it in case there's something odd with the serialization.

public class Data
{
    public string ColumnName;
    public double Value;
    public string Date;

    public Data(string name, double price, string date)
    {
        ColumnName = name;
        Value = price;
        Date = date;
    }
}

Hello Richard.

Sadly, I am still unable to get the charts to display using the search criteria. Cry | :((

I also noticed, my data.cs file is under App_code, could this be issuing the blank charts on the client-side.

I really appreciate your help and time.
Thanks a million.

I doubt having the file under App_Code would make any difference.

Here's the entire file I'm using to test. I have a different master page, a different file name, and I'm not using a code-behind, but otherwise everything should be the same:

ASP

<%@ Page Language="C#"
    MasterPageFile="~/_controls/Site.master"
    Title="Chart Test"
%>

<%@ Import Namespace="System.Web.Services" %>

<script runat="server">

public class Data
{
    public string ColumnName;
    public double Value;
    public string Date;

    public Data(string name, double price, string date)
    {
        ColumnName = name;
        Value = price;
        Date = date;
    }
}

[WebMethod]
public static List<Data> GetData(string name)
{
    var dataList = new List<Data>();

    dataList.Add(new Data("CLAVS 2007-1 M2A", 77, "Oct"));
    dataList.Add(new Data("CLAVS 2007-1 M2A", 0, "Oct"));
    dataList.Add(new Data("CLAVS 2007-1 M2A", 78, "Oct"));
    dataList.Add(new Data("CLAVS 2007-1 M2A", 82, "Oct"));
    dataList.Add(new Data("CLAVS 2007-1 M2A", 425, "Oct"));
    dataList.Add(new Data("CLAVS 2007-1 M2A", 79, "Oct"));
    dataList.Add(new Data("CLAVS 2007-1 M2A", 80, "Oct"));
    dataList.Add(new Data("CLAVS 2007-1 M2A", 57, "Oct"));
    dataList.Add(new Data("CLAVS 2007-1 M2A", 77, "Oct"));
    dataList.Add(new Data("ACCDO 11A B", 2, "Sept"));
    dataList.Add(new Data("ACCDO 11A B", 2, "Sept"));
    dataList.Add(new Data("AELIS 2013-IRAR C", 96.89, "Sept"));

ASP Buttons event not firing

11-Nov-13 3:28

Dear Richard,

Apology for the late response. I am writing to sincerely thank you for helping me on this small task. I really appreciate your support and time into this post. After long struggle, I manage to find the cause of problem which was syntax errors in the #button.click javascript code.

JavaScript

$(document).ready(function () {
           $('#Button2').click(function () {
               $.ajax({
                   type: 'POST',
                   dataType: 'json',
                   contentType: 'application/json',
                   url: 'Default.aspx/GetData',
                   data: "{name:'" + $("#SearchText").val() + "'}",
                   success:
                   function (response) {
                       drawVisualization(response.d);
                   }

               });
               return false;

           });
       });

Thanks a million for help. Have a great day.
Kind regards

Hey all,

I have got a problem with my buttons on my website, the buttons not always causing a postback, sometimes it works and sometime it does not, the buttons CausesValidation are set to false. I am not getting any javascript or server side errors.

Any Idea that will cause this issue?

If you have CausesValidation set to True and you are not getting a postback, then it's possible that your validation controls are firing and not being displayed.

If you have validation controls set up make sure they are displayed properly to a ValidationSummary control. You could also set your CausesValidation property to False to by pass the validation and make sure it's hitting the server.

Hey Joshua,

I have solved the issue, it was my ComponentArt menu on my master page, I have read that it's a common issue with ComponentArt 2007 and framework 3.5, I decided to scrap the component and create my menu from scratch.

MVC4 Ajax call does not reach controller method

I am new to MVC4. I am trying to issue ajax call on the button click to receive partial view with the loaded dropdown list. It looks like Ajax call never reaches controller's method GetMyList(). What is wrong with my code ? Thank you

//in mypage.cshtml
@model IEnumerable<MyProject.Models.MyModel>
@{
ViewBag.Title = "MyPage";
Layout = "~/Views/Shared/_MyLayout.cshtml";
}

</div>

<div id="divWithPartialView">
@Html.Partial("_MyPartialView", Model) // displayed on initial page load
</div>
...
</div>

@section MySection{

<script type="text/javascript">

$('#btnGetList').on('click', function (event) {

alert("go get list"); // shows up

var myName = "Jo";

$.ajax({
type: "POST",
url: "Main/GetMyList",
data: myName,
success: function (data) {
alert("list is here"); //does Not show up
$("#divWithPartialView").html(data);
}

});

alert("after ajax"); //shows up

})
</script>
}

// Controller

public ActionResult MyPage()
{

return View(myList);
}

public ActionResult GetMyList(string myName)
{
MyModel mm = new MyModel();
List<MyModel> myList = mm.GetNames(myName); // using search criteria entered on the previous Application page

return PartialView("_MyPartialView", myList);

}
}
}

//Partial View: _MyPartialView.cshtml
