Get A Reference To The Current Class (ascx Or Aspx) Given A Member Object?
Mar 14, 2011Given an instance of a control SomeControl that is in a some file (could be a usercontrol/ascx, or an aspx) how can I get a reference to the class to which it belongs?
In a usercontrol, SomeControl.NamingContainer seems to be reliable.
In a page that inherits from a MasterPage, this will return a reference to the ContentPlaceHolder, not the actual class that defines the aspx. What I would want in that case is SomeControl.Page
Parent will return the parent control in the heirarchy so isn't much use.
Is there any method for getting this directly regardless of what kind of thing it is?
Variables - Using Of Module Private Member Instead Of Application Or Cache Object In Project
Sep 1, 2010In an ASP.NET web app written in VB.NET, I need to load and store a large read-only hash table that is frequently accessed by the application. It only needs to be loaded once on application start, is never updated and can be accessed by any session at any time.
If I load the hash table into a private member in a (global) module, a lookup to it takes one 20th of the time compared to storing the hash table in the Application or Cache object. Is there any reason why I should not do this, or should Application or Cache always be used to store in-memory objects in an ASP.NET web application?
Web Forms :: How To Sign A Potential Member On Member Role With Create User Wizard
Feb 25, 2010I have two member roles at my project:
1.) Administrator
2.) Member
From the toolbox in Visual Studio 2008, I have dragged and dropped the create user wizard into the stage. I aim that a guest can register itself and automatically join the "member" role. Not the role "administrator". How can I do that?
MVC :: Model With List As Member: Member Always Null After Submit?
Nov 25, 2010I have following model class:
public class WebModel
{
public List<ArticleModel> Articles { get; set; }
}
public class ArticleModel
{
public int ID { get; set; }
public double ValueParam { get; set; }
}
Then I have the controller with the two actions:
[Authorize]
public ActionResult Index()
{
WebModel model = new WebModel();
ModelConverter.ConvertToModel(model, controller);
return View(model);
}
[Authorize]
[HttpPost]
[ValidateInput(false)]
public ActionResult Index(WebModel model, string saveButton)
{
ModelValidation.ValidateWebModel(model, ModelState);
if (ModelState.IsValid)
{
return RedirectToAction("Create", "Article");
}
ModelConverter.ConvertToModel(model, controller);
return View(model);
}
And this is my view:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Web.Models.WebModel>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
<%var controller = Session["controller"] as Web.Code.SessionController; %>
<%Html.BeginForm(); %>
<div>
<table width="100%">
<%foreach (var article in Model.Articles)
{%>
<tr style="text-align: right">
<td>
<%:Html.DropDownListFor(m=>m.Articles.FirstOrDefault(f=>f.ID == article.ID).ID, new SelectList(controller.CurrentProdukt.Articles.AsEnumerable(), "ID", "Name", article.ID)) %>
</td>
<td>
<%:Html.TextBoxFor(m => m.Articles.FirstOrDefault(f => f.ID == article.ID).ValueParam)%>
</td>
</tr>
<%} %>
</table>
</div>
<table style="width: 100%">
<tr>
<td>
<input type="submit" name="saveButton" value="Save" />
</td>
</tr>
</table>
<%Html.EndForm(); %>
</asp:Content>
If I press the submit button, I get to the second action method in the controller (the one with the HttpPost attribute). In this action, the object model itself is not null, but the "Articles" list inside is null.

MVC :: Reference To A Non-shared Member Requires An Object Reference In Code Generated?
Oct 4, 2010I am working on converting a project from C# to VB and am facing this weird issue. 1 page cannot compile and I get the reference error, but the weird thing is that the compiler shows the error as coming from ASP.NET generated code. Visual Studio shows me that error is coming from my ASPX page. I cannot seem to figure out why or where this error is occuring. Also if I take the inherits attribute out I don't get the compilation error. The code in aspx page is below:

C# - Declare And Use The Name Of A Function From A Json Object?
Apr 20, 2010I have a json object collection of geo locations that I build in the server. Each of those objects has two properties: "marker" and "onClick". Marker is for storing a Google Maps marker object and the onClick stores the name of the function to be called when that marker is clicked on the map.When I'm pushing the location objects into an array using javascript in the client side, I create the markers and assign them to each location object within the array.
My problem is that when I bind the marker with the onClick property, the function won't be found in the DOM and get an error.Is there a way to declare a property in a json object for using it on an event binding?

How To Call Javascript Function On A Silverlight 3 Object
Jan 12, 2010I have the following Silverlight control defined:
[Code]....
I have exposed the following method in my Silverlight control (Page.xaml.cs) to be accessible to Javascript:
[ScriptableMember]
public bool HasPendingUpdates()
{
return btnSave.IsEnabled;
}
I then have a Javascript test function in my aspx page that is trying to do something with it:
var imageViewer = $("#objImageViewer")[0];
if (imageViewer.Content.Page.HasPendingUpdates())
{
alert("Pending Changes Exist!");
}
else
{
alert("NO Pending Changes Exist!");
}
Problem is that it fails after the Content object. I have tested the following:
var imageViewer = $("#objImageViewer")[0];
imageViewer // Valid
imageViewer.Content // Valid
imageViewer.Content.Page // Invalid
imageViewer.Content.HasPendingUpdates() // Invalid
So I am not sure what I am doing wrong. How do I get to the function within Content?
I am using IE8, Silverlight 3, ASP.NET. The silverlight control is created with the object tag as I don't think the control is an option in Silverlight 3+.

Passing A JSON Object To A Function On Server Side?
Jun 4, 2010I'm trying to create a JSON object on client-side and pass to a server-side function. Then instantiate it on server-side using JSON string representation.
So I create jSON object on client-side
var myJsonObject = {
"arg1": var1,
"arg2": var2
}
and pass it in to
WebForm_DoCallback(controlID, myJsonObject , null, null, null, true);
When I try to retrieve this JSON object on server-size I get as a string representation of JSON [object Object]
So in following server-side function, the argument value is [object Object]
public void RaiseCallbackEvent(string jsonObj)
I was expecting a string representation of JSON object. How do I pass in a string representation?

Javascript Error - This.node.onload=function() Is Null Or Not An Object
Oct 27, 2010I am working on ASP.NET 3.5, c#, visual studio 2010. I have made a master file and a default page that uses this master file. I have placed a couple asp:contentplaceholders in the master and corresponding code in the page that uses this master. I have also inserted JavaScript like this in the content page (and not the master):
<asp:Content ID="Content6" ContentPlaceHolderID="Mainpage" Runat="Server">
<script src="path1" type="text/javascript"></script>
<script src="path2" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
var options = {
//some java code
};
$(".mycssclass").effect(options);
});
</script>
</asp:Content>
On running the website I get the following runtime error in visual studio: Microsoft JScript runtime error: 'this.node' is null or not an object and it point to some function inside the JavaScript like this.node.onload=function(){..............//I am not a java guy so do not know much about this Where am I going wrong? Why does the site compile correctly but throw this runtime error? I also tried inserting this java code inside the master file in the <head>, but same error.
Passing JQuery Object And WebMethod Return Value To OnSuccess Function
Mar 31, 2010I am calling a WebMethod from this code:
if($(this).attr("checked")) {
..
MyWebMethod(variable1, variable2, onSuccessFunction);
}
The MyWebMethod returns an integer, and I want to set $(this).attr("id") of the jQuery object above to the returned integer. Basically, I'm trying to do the equivalent of an MVC Ajax.ActionLink...AjaxOptions {UpdateTargetID =...} However, I can't figure out how to get both a reference to $(this) as well as the returned value. For example, if I do:
MyWebMethod(variable1, variable2, onSuccessFunction($(this)));
I can succesfully manipulate the jQuery object, but obviously it doesn't have the return value from the MyWebMethod. Alternatively, the first code block with a method signature of onSuccessFunction(returnValue) has the correct return value from MyWebMethod, but no concept of the jQuery object I'm looking for. Am I going about this all wrong?
