Is that possible? The reason why am doing this is because I need to parse that variable into a an JQuery function so I wanted JQuery to read that field. Can I Assign that value in base class or I have to do it within default.aspx pageload method?
View 1 RepliesI have a MasterPage project which is a class library project (it includes themes, style sheets, menus etc) and all applications use them.
I am using the BasePage concept for dynamically adding title,meta tags and descriptions. This BasePage Class inherits system.UI.Page and the aspx pages in the project inherits the BasePage class.
Now i need to move this BasePage class from my application to the Master Page Project so that all the projects/applications can reuse the same code.
I tried add the basepage.cs in the App_code folder and tried calling it in the page directive like below
<%@
Page
Language="C#"
MasterPageFile="~/Master/Layout/MasterPage.master"
AutoEventWireup="true"
CodeBehind="xxxx.aspx.cs"
CodeFile="xxxx.aspx.cs"
Inherits="xxxx"
ValidateRequest="false"
EnableEventValidation="false"
ViewStateEncryptionMode="Never"
CodeFileBaseClass="~/Master/App_Code/BasePage<Page>"
Title="Title"
Meta_Keywords="xxxx,yyyy,zzzz"
Meta_Description="This is a test" %>
But i am getting error
Could not load type '~/Master/App_Code/BasePage<Page>'.
This was working fine till the BasePage class was inside the application. But once i moved it out of the project and added it to the master page project i getting this error.
What cool functionality and methods do you add to your ASP.net BasePage : System.Web.UI.Page classes? Here's something I use for authentication, and I'd like to hear your opinions on this:
protected override void OnPreInit(EventArgs e)
{
base.OnPreInit(e);
// Authentication code omitted... Essentially same as below.
if (_RequiresAuthentication && !(IsAuthorized))
{
RespondForbidden("You do not have permissions to view this page.", UnauthorizedRedirect);
return;
}
}
// This function is overridden in each page subclass and fitted to each page's
// own authorization requirements.
// This also allows cascading authorization checks,
// e.g: User has permission to view page? No - base.IsAuthorized - Is user an admin?
protected virtual bool IsAuthorized
{
get { return true; }
}
My BasePage class contains an instance of this class:
public class StatusCodeResponse {
public StatusCodeResponse(HttpContext context) {
this._context = context;
}
/// <summary>
/// Responds with a specified status code, and if specified - transfers to a page.
/// </summary>
private void RespondStatusCode(HttpContext context, System.Net.HttpStatusCode status, string message, string transfer)
{
if (string.IsNullOrEmpty(transfer))
{
throw new HttpException((int)status, message);
}
context.Response.StatusCode = (int)status;
context.Response.StatusDescription = message;
context.Server.Transfer(transfer);
}
public void RespondForbidden(string message, string transfer)
{
RespondStatusCode(this._context, System.Net.HttpStatusCode.Forbidden, message, transfer);
}
// And a few more like these...
}
As a side note, this could be accomplished using extension methods for the HttpResponse object. And another method I find quite handy for parsing querystring int arguments:
public bool ParseId(string field, out int result)
{
return (int.TryParse(Request.QueryString[field], out result) && result > 0);
}
how am I be able to assign a value to my hidden field control? I have this web service that returns member's ID and name (e.g. 0001-John dela Vega). In order for me to search for a member, I'm using an autocomplete extender, now, if in case that I found the member I'd like to assign its member id to a hidden field. I ask this because I'd like to change the way my web service return data so instead of displaying the member's id and name at the same, I'll just show its member name.
View 1 Repliesi have a dropdownlist control in asp.net which resides in a user control .The yuser control has a updatepannel .I want to set the dropdown selected value to a hidden field .How will i do this in javascript /Jquery .I don't want to use server code?
View 3 RepliesI'm struggling to read an int from the hidden field on aspx page.
<input type = "hidden" id = "myIntegerId" name = "integerId" value= "<%: Model.MyObjectId %>" runat = "server" />
The value is definately on the form, I can see it in the debugger and print it with <%: %>
When I read the form values in the controller, instead of an int I recieve a following string: <%: Model.MyObjectId %>
I have tried casting data in the hidden field to string and calling ToString() method on that field, neither has worked.
The data is submitted using the post event.
I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
i would like to call the external js file's function onclientclick event, but how can i pass the parameter, which i get from the hidden field value from the same aspx file.
<asp:button id="btn" onclientclick="javascript:test(hidden_field);"/>
I am beginner in web applications development. I started one little project and host it on source forge "https://homoco.svn.sourceforge.net/svnroot/homoco". And I started implementing authentication in this application to learn how it works. From my experience people never use out of the box things so I want to implement this stuff alone (like in real world projects). So some questions:
1) Is there any reason to use membership out of the box? To use database table schema, stored procedures etc. that tool generate for developer. I think that this lower control over code and I decided to implement it my self. I don't know if I am right.
2) Is my approach in this demo project good or bad (if someone have time I like to do just a little code review)? I created database based on business rules. Not using database schema that membership provider require. Extend "MembershipProvider" class to satisfy my needs. Implement queries to database myself.
3) Now, this question is a little wired but I have to ask it. If we make custom Membership Provider and do sql queries alone, implement all MembershipProvider class methods ourselves, and in application use Membership.blabla() why is this approach different from not extending MembershipProvider class and putting all this methods in some unique class and call its methods then? I hope that someone understand what I ask here.
I am sorry for three questions, but I really trying to find the best way to implement this feature in my demo project like it is a real world application.
I have a user control that i have registered to an aspx page. Now from the aspx page, i am trying to access one of the registered usercontrol's hiddenfield value in my aspx page using javacript using the below code:
tst = document.getElementById('control1$hdnField').value;
I looked into the page's trace, and i could see 'control1$hdnField'. Then why i am not getting its value in my aspx page. I have also confirmed that the hidden field by this name exists in the user control and also has a default value set.
Looking for sample to access the hidden variable which is declared in the aspx page in the webmethod.
View 1 RepliesUsing MySQL 5.
In my SAP.NEt project, defined a constant:

We are trying to use a BasePage class (which inherits from Page) to populate and set the Meta Keywords and Meta Description Tags. I am using masterpages and below is an example code extract... According to examples on the internet, I could then set this also via the Page Directive using the MetaKeywords and MetaDescription properties, but they do not appear.
I have tried setting the CodeFileBaseClass="MyNamespace.UI.BasePage" but this does not work either. Using debug I can see that the BasePage classes' MetaKeywords and MetaDescription properties are not being set within my content page. I can access the properties but not set them.

We are using nested master page the master page is seperate class library project and all the other projects refer to them. We wanted to have a basepage class which load title, meta tags and keywords dynamically. It was working fine till it was inside the main project. We wanted the basepage class to be more generic and to have it reside in a single place. So i tried created a seperate class library project but i getting error "Could not load type" ..
How to have the basepage class outside the project?

I have a 2D array of doubles in my Default class on my Default.aspx.cs page, like so:
protected Double[,] time;
By the time the page loads, I have populated this array from a database. Now, I want to reference this array in another file (Diff.aspx.cs) to avoid visiting the database again. Also, the data is used in a read-only fashion.
here is the code, where i am confused what to write in all the properties and functions of the base class stream?

Question. Say for example if i have a business entity -> Customer, which has customerId, customerName and customerType. I have created an asp:Hidden Variable hdnCustomer to runat="server"
If i wanted to serialize the value of the customer business entity (in the code behind) to the hdnCustomer then how would i do that?
// Psudo code
Collection customerList = new Collection();
customerList = BusinessAccess.GetCustomerList();
hdnCustomer = serialize and assign the value of 'customerList' to hdnCustomer;
...
...
// Later on a select index change of one of the drop down lists
inside the event handler for the drop down list
{
Collection customerList = new Collection();
customerList = deserialize the value from hdnCustomer
int a = Convert.ToInt32(ddlDropDown.SelectedValue);
foreach(a in customerList)
{
// Do something
}
}
I am trying to secure very mixed content that is located in an ASP.NET directory. For purposes of this question, it can be ~/MyApp/.
I want all of the content in the directory and its subdirectories restricted to authenticated users. The default.aspx page, though, should be accessible to everyone. This is the web.config in that directory:
[Code]....
Now if you are an unauthenticated user, everything works fine if you request [code]....
The problem occurs in that visitors do not always request "Default.aspx". We have a default document configured so that they get Default.aspx even if they just request "/MyApp". An authenticated user works fine, but an unauthenticated user is directed to the login page.
Now I know that essentially this happens because even though the request for "/MyApp/" will actually end up serving up "/MyApp/Default.aspx", the security system is only checking for "/MyApp/" since that is what I requested. That is then getting the default security for the directory.
How can you configure an exception to allow access when no particular file is requested in the directory??
Is there some dependency between DefaultDocumentModule and UrlAuthorizationModule? In this environment, the UrlAuthorizationModule has been removed and re-added in order to make sure it fires for non-managed requests. I would not expect that to change the order of execution, though, since UrlAuthorizationModule usually goes after DefaultDocument.
A workaround could be to set up the opposite security with the directory being open, and then trying to secure individual files. Because of the (changing) number of files, and extensions, etc, and the fact that you cannot use wildcards in a <location>, this is not really a workable solution for me.
I'd like to inherit all my controllers from a custom base class that I write myself. I can change the line every time I add a new controller, but it would be nicer if I could somewhere specify the default value that gets set there. That way I wouldn't need to worry about forgetting this, and other people who get added to the project later on would have an easier time.
