Not from javascript.

But you can create a web service (in the middle) that grabs the json using the "secret url" then forwards its content to the end user.

The only way to completely hide the URL from the user is to make the request on the server-side. Even if you obfuscate your javascript, most browsers have developer tools which can log network requests.

The simplest option is probably to create a page on your site which loads the data from the remote service and echoes it directly to the response. That way, your script can call a page on your site without having to pass the API key.

UpdatePanel + Timer = Not Working

GenJerDan28-Mar-14 7:15

A simple asp.net page: GridView in an UpdatePanel with a timer to refresh the data every minute.

Works Fine On My Machine, hitting IIS Express.

Doesn't ever refresh when deployed to the actual IIS server. It just sits there and laughs at me.

I've tried various combinations of Timer outside the UpdatePanel with the AsynPostBackTrigger set, Timer inside UpdatePanel with no trigger set. Timer tick explicitly saying to update the UpdatePanel. Etc etc etc, just like the two million Google hits suggest, to no avail.

Every "fix" works fine on my machine.

It just refuses to work on the server.

Is there an IIS setting of some sort that might be causing it? Elsewhere on the page (outside the UpdatePanel) is a Panel with the CollapsiblePanel extender tacked on which works fine, so it isn't a matter of Ajax not being there. Looking at the webpage source from the server and from VS, I see no differences other than the extra crap VS puts in when hosting.

relevent code:

XML

<asp:Timer ID="Timer1" runat="server" OnTick="Timer1_Tick" Interval="60000" Enabled="true" EnableViewState="False">
                                </asp:Timer>
                        <asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="false" UpdateMode="Conditional" EnableViewState="False">

                            <Triggers>

                                <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />

                            </Triggers>

                            <ContentTemplate>
                                <asp:Label ID="lblLast" runat="server" Text="Newest Order: (waiting for update)" EnableViewState="False"></asp:Label>

                                <asp:Label ID="lblStatus" runat="server" Text="Checking for orders..." Visible="False" EnableViewState="False"></asp:Label>
                                <div class="Refreshed">
                                    <asp:Label ID="lblRefresh" runat="server" CssClass="Refreshed" Text="Last Refreshed:" EnableViewState="False"></asp:Label>
                                </div>
                                <br />
                                <asp:GridView ID="grdStatus" runat="server" AutoGenerateColumns="False" CellPadding="4" ForeColor="#333333" Width="100%" CssClass="Grid" EnableViewState="False">

and

protected void Timer1_Tick(object sender, EventArgs e)
{
    string Wards = Session["Wards"].ToString();
    RefreshGrid(Wards);
}

(Ye, I'll rename things if I ever get it to work.)

HTML5's new inputs. Black boxes that make layout a living hell?

Sergejack28-Mar-14 3:22

There are some HTML content which designers has barely control over.
For instance, laying out checkboxes requires a lot of tricks (as far as I know).
Without those tricks, checkboxes can really mess the layout.

For instance (I hope it'll help showing my point) I once had a page having parts using a very big high font-size and having a few checkboxes. On many browsers, the font-size didn't cause a scale of checkboxes. Thus side to some huge text were normal (microscopic looking) checkboxes.

With new inputs like "range", "date", etc. there are now many new element which one doesn't have css control over.

Thus I'm wondering if I should avoid using such inputs.
Or maybe am I missing an important point.

Wath do you think?

I'm not aware of the problem you describe here...
It may be a browser support problem? Different browsers has different support level...
You may give us a specific sample to show your problem?

You could take a look at "range" for instance.
It display slightly differently on different browser.

And you can't set its height in firefox for instance.
So if you make a page whose sole/main purpose is to set a ranged value. And wish to make the slider bigger (the bigger it is, the easier it is for the end user) you actually can't.
Same would go it you were using a checkbox.

I've seen now what are you talking about. I thought you have problem with HTML 5 itself, but it's clear that the problem is with implementation in different browsers.
There is nothing - except opening bug report with the browsers - you can do about it.
HTML 5 is still in 'Candidate Recommendation' state, so things can change...
You may look for JavaScript libraries that aim to provide HTML 5 support for older browser, and try it on FF...

I have seen the tiny check-boxes, myself, on IE8 (most of people here still use that). As you've heard, time and again, IE doesn't play well with others. I've also had layout problems on local vs. thin-client views using the same browser (IE8 or latest FireFox).

One solution I've been forced into is most layouts are now done with position:absolute. In particular, sized and position designated by % were troublesome.

Check-box layout hasn't been a problem, even when created by AJAX. A desperate solution to the positioning could be to create a element to contain your check-boxes, each in it's own column;

MVC WebAPI Controller Parameter Null

Kevin Marois27-Mar-14 10:04

Kevin Marois

27-Mar-14 10:04

First, I a VERY new to WebAPI's and Web development overall, so please bear with me...

I'm calling this method on my controller:

[HttpGet]
public List<DateTime> GetDaysForAssignment(GetDaysForAssignmentEntity entity)
{
    return BO.GetDaysForAssignment(entity);
}

The GetDaysForAssignmentEntity entity is

[DataContract]
[Serializable]
public class GetDaysForAssignmentEntity : _BaseEntity
{
    [DataMember]
    public DateTime BeginDate { get; set; }

    [DataMember]
    public DateTime EndDate { get; set; }

    [DataMember]
    public string PhaseName { get; set; }

    [DataMember]
    public DateTime PhaseStartDate { get; set; }

    [DataMember]
    public string ShiftName { get; set; }

    [DataMember]
    public DateTime ShiftStartTime { get; set; }

    [DataMember]
    public DateTime AssignmentDate { get; set; }
}

Here's my proxy method:

public List<DateTime> GetDaysForAssignment(GetDaysForAssignmentEntity entity)
{
    WebAPIExecutor webAPIExecutor = new WebAPIExecutor("/JobAssignmentHeader/GetDaysForAssignment/", Method.GET);
    webAPIExecutor.AddParameter(entity, "entity");
    List<DateTime> results = webAPIExecutor.Execute<List<DateTime>>();
    return results;
}

I didn't the post the WebAPIExecutor code because it's working in hundreds of other places. I'll post it an anyone needs to see it.

When I make the call, when I get into the controller, the parameter is null.

I really have no clue how to debug this. I appreciate your help.

Complex types by default are resolved from the Body of request, which a Get doesn't use.
Try either
changing the parameter to an integer id
of the parameter to [FromUri] GetDaysForAssignmentEntity entity)

Thanks for the reply. Like I said, I'm very new to Web development.

Can you explain this a bit more.

Matthew Dennis wrote:

Also, I changed it to an HttpPost and it worked, although I don't know why.

I'm no guru, so take this as a guess:

With a Get and parameters are passed from client to server via the URL

e.g.

http://www.myCompany.com/myApplication/myFunction?Id=1640&action=r

Where the two parameters being sent are Id and action.

Fine in this example where Id is an integer and action a character.

But if one of the paramters was a complex object, how do you encode it in a url?

Answer - you don't! You use a Post - which puts parameters in the body which is sent to the server and decoded.

So changing to a Post allowed your complex object to be passed to the web api

the regno can be inserted more than once as well as level and session, also courseid but with previous regno.

i need to prevent duplicate rows with regno, courseid, level, session, on a row.

You have a couple of options.

1. Add a unique index so MySql will not allow it.
2. When you are inserting records first check to see if it exists already.
