C# - How To Utilize A Rest API In 3.5
Nov 29, 2010I have been given some basic documentation of the RazorGator REST API and need to incorporate it into an ASP.NET 3.5 site. I've created my class file to call the API which contains my WebRequest.Create ("URL TO API"). How do I then make the output available so that it can be consumed by other pages? That is, the tickets.aspx page needs to obtain the output results of this API call. What constructs should I use to make this available in tickets.aspx?
Edit
Here's the code I've written thus far:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;
using System.Net;
using System.Text;
namespace SeatEater.Web.UI.search
{
public class RazorGatorService
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://api.razorgator.com/ticketservice/ticets.xml?blahblah") as HttpWebRequest ;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream receiveStream = response.GetResponseStream();
StreamReader readStream = new StreamReader(receiveStream, encode);
response.close();
readStream.close();
}
}
I receive the error message:
A field initializer cannot reference the nonstatic field, method, or property 'field'
in the second line of the above codeblock. I'm very new to using HttpWebRequest and HttpWebResponse. Can you advise me as to how to rectify the error message I'm receiving?
Utilize A 3rd Party API In VB.NET?
Mar 17, 2011I know this may be a simple answer or at least to most people but I'm not getting anywhere when attempting this on my own or through the various resources I have looked up.
Here is my issue:
I am using ASP/VB.NET to build this integration. Visual Studio 2008. I previously had asked a question on API Integration on here and utilized that information to successfully perform the next steps. As this API is written differently I may not be grasping the appropriate functions correctly.
A company has given me several addresses for .ASMX portals. I add these into my service references. I can successfully see objects in my object browser and see all the procedures, etc., but further from here I'm unable to correctly use any objects. I attempted to replicate the integration based on my last API question and advice: Connecting to an API offered by a Company. When I'm attempting to use an object or simply relate a field to something on my script I continually get an error.
For example:
Dim A as New API.AddFunction
A.AccountNo = "123"
When running the page:
Object reference not set to an instance of an object.
Here is only one .ASMX I was given. I cannot release any more, until I receive permission to do so from the provider, I apologize.
[URL]
Anyhow, the root of my question is really how do I correctly interface with this API? What information do responders require so I can clarify this question more?

View 1 RepliesAJAX :: Trying To Utilize An AnimationExtender That Will Fade?
Mar 10, 2010I am trying to utilize an AnimationExtender that will fade in an asp:LinkButton. My page includes 4 user controls that each load information at different intervals. What I am wanting to do is fade in the asp:LinkButton after the last user control has loaded. I have tried using <OnLoad> but the fade in occurs while the user controls are still loading. I have also tried wrapping the user controls in a panel (seen below), using the panel as the TargetControlID of the AnimationExtender. My end goal here is pretty simple: The user should not see the asp:LinkButton until after the page (including the 4 user controls) has loaded.
Here is my markup for this seciont of code:
<div>

<h2>Header Text</h2>
<div>
<cc1:AnimationExtender ID="AnimationExtender1" runat="server" TargetControlID="Panel1">

<FadeIn Duration="2" Fps="20" AnimationTarget="LinkButton1"></FadeIn>

View 1 RepliesHow To Utilize Or Mimic Application OnStart In HttpModule
Apr 2, 2010We are trying to remove the global.asax from our many web applications in favor of HttpModules that are in a common code base. This works really well for many application events such as BeginRequest and PostAuthentication, but there is no Application Start event exposed in the HttpModule.
I can think of a couple of smelly ways to overcome this deficit. For example, I can probably do this:
protected virtual void BeginRequest(object sender, EventArgs e)
{
Log.Debug("Entered BeginRequest...");
var app = HttpContext.Current.Application;
var hasBeenSet app["HasBeenExecuted"] == null ? false : true;
if(!hasBeenSet)
{
app.Lock();
// ... do app level code
app.Add("HasBeenExecuted", true);
app.Unlock();
}
// do regular begin request stuff ...
}
But this just doesn't smell well to me.
What is the best way to invoke some application begin logic without having a global.asax?
Web Forms :: Dynamic Controls Depend On Type Of Control?
Apr 8, 2010I then found an excellent tutorial with code! It is the following: [URL] It works perfectly but only with TextBox controls. Change the TextBox to Label and it doesn't work (neither will ListBox). I have been trying to get it to work and it may have something to do with ViewState not being enabled for these other controls. I managed to get around the MasterPage and container problems, but can't get it to work with either Labels or ListBoxes. (As I understand it, the Load View State stage is not re-populating the controls from the previous time it was posted for these other two controls.) Does anybody know how? If I could get the C# code working (with Label instead of TextBox, e.g.)

View 6 RepliesMVC :: RenderPartial To String For JsonResult While Maintaining Testability?
Mar 28, 2010I would like to wrap a RenderPartial in a JsonResult so that my jQuery can handle placement/positioning of the html data based on additional Json parameters.
e.g. {html: <string returned from RenderPartial>, typeofdata: 1}
After Googling, it seems that the only way to do this is a workaround that hijacks HttpContext in order to spit the PartialViewResult into a string. However, this seems like it would break testability.
Is JsonResult not intended to be used with RenderPartial?
Alternatively, I could set typeofdata as a parameter of the model, and have the PartialView render it as a hidden field, then have jQuery look for it. What is a better way to generate the data that I need?

C# - Retrieving Selected Item Text Within A JsonResult Function
Mar 3, 2011I am creating an MVC project with a table using the JQGrid plugin. I would like to use a DropDownList to allow the user to specify a value, that will be used in an SQL query to retrieve specific data from the table. I.e. user can select a country from the list, and the table will display items only from that country. I cannot figure out how to retrieve the selected item from the DropDownList, within my data bind function for my table, within my controller class.
DropDownList in the View
<%= Html.DropDownList("Countries")%>

//dt is a DataTable which holds the values for my list
