I am facing challenge of changing action attribute of html form tag. As my application is on shared hosting (medium trust) environment of godaddy server, I cannot use reflection to get control adapter of html tag page. So, I cannot use the following code in my Url Rewriting module.
[Code]....
Is there any otherway to implement the same functionality without reflection?
I have an app I am transitioning to MVC3 to see what the upgrade path is essentially. I've hit a snag. I believe I've run into a change that may be due to the changes for Dependency Injection in action filter attributes, but I have been unable to track down the cause, and the "correct" solution.This project uses StructureMap and NHibernate. The NHibernate session is started at the beginning of each request, and ends at the end of each request, thanks to a small module. This is just to give an idea of the stack involved...o I have a few custom Authorize attributes (Inheriting from AuthorizeAttribute) that perform some more complicated authorization logic for specific actions that they decorate. Part of their functionality involves using two repositories which they must either (a) have injected, or (b) get from the StructureMap ObjectFactory themselves. In MVC2 I was using option b, so that the CONSTRUCTOR of the attribute looked like this:
[Code]....
This worked fine, as in MVC2 the constructor was called each time the attribute was evaluated. This BREAKS in MVC3, where it would appear that this is no longer the case. Due to this apparent change, the FIRST time this attribute is evaluated, it runs fine, but each subsequent time, any calls in the repositories fails because it claims the NHibernate Session object hasn't been started! The reason being, as far as I can tell, that the CustomAuthorizeAttribute is created once, and then held in whatever state it exists in at that point for the lifetime of the application... Which means that the dependencies inside of it (Which SHOULD go out of scope at the end of each request, and be reinstantiated / fetched at the beginning of subsequent requests), are instead persisting with it becoming stale after the first evaluation.After banging my head against the desk for a few hours, I realized that simply moving these calls to the ObjectFactory into the AutorizeCore method made everything work again.Now, all of this was of course, a hack, because there wasn't a good easy to do real dependency injection into attributes in MVC2. I hear that is changed in MVC3, and I am wondering if this behavior is in response this change, and if so, what do I need to do to make this work?
I am loading the dll as shown below,
Type[] _Type = Assembly.GetAssembly(typeof(StdAdapter)).GetTypes();
Now I want to get all the properties for a particular 'class name' which is being passed as a string.
I am trying to create instance of class by using reflection in ASP.net web site. Class ClassName is defined and located in App_code folder. Following line returns null, what could be wrong.
Type type = Type.GetType("NameSpace.ClassName", false, true);
I have a hyper link control and I set the NavigateURL and the ImageURL property at runtime. I also need to set the class of the image tag that it generates but I cannot figure out how I can do that. The solution mentioned here [URL] does not work because the image url is hard coded.
View 2 RepliesI want to retrieve private (implementation and other) methods of a class which implements an interface and also is derived from (inherits) a base class.
How can I achieve this using reflection? Is there anyother way to achieve this?
This is wat m tryin to do. I need to view these private methods and their contents, I don't want to invoke them.
Dim assembly As System.Reflection.Assembly
Dim assemblyName As String assemblyName = System.IO.Path.GetFullPath("xyz.dll")
assembly = System.Reflection.Assembly.LoadFile(assemblyName)
assembly.GetType("myClass").Getmethods(Bindings.NonPublic)
assembly.GetType("myClass").GetMethods(BindingFlags.NonPublic) isn't working
I have a set of links that exist in the master page. I have a css class i would like to assign to a particular one of them depending on if that is the page you are at during page load. ex: Home will have the current_page_item class if you are at the index page
This is what I have:
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
DirectCast(Me.Master.FindControl("ctl00_homeLi"), HtmlGenericControl).Attributes.Add("class", "'current_page_item'")
End Sub
can we create form action in asp.net or not ?

i have a user web control wich has the website menu. this menu is viewed through out the entire web site.
i would like to mark the selected link, on the menu with in the web user control,in some way (red background or w/e) the thing is, i cannot manage this from client side since there is a page_load on every click on the menu (witch brings up a different page). the only thing i can think of is saving the click to the session and then retrieve what was clicked and change the style accordingly via c# in the code behind.
can anyone make it clear the main purpose of action attribute of form tag in html page?

I created a simple Master Page in Visual Studio 2008:
<%@
Master
Language="VB"
CodeFile="MasterPage.master.vb"
Inherits="MasterPage" %>
<!DOCTYPE
html
PUBLIC
"-//W3C//DTD XHTML 1.0 Transitional//EN"
and got green underlined 'Master' with two warning messages: 1.Validation (ASP.NET): This attribute name must be followed byan equal (=) sign and a value. If the value is in quotation marks, the quotation marks must match. 2. Validation (ASP.NET): Attribute 'Master' is not a valid attribute of element 'Control'.How I can get rid of the messages?
I have an existing class for an input, is it possible to add an additional class for the object in C#.net, instead of doing a if/else and not having a preset class on the object in the first place?

View 2 RepliesI have a form action in an ASCX page set to an external URL
<form id="fLoginForm" runat="server" action="http://external.url" method="post" defaultbutton="bSignIn">
Inside there is a standard ASP linkbutton
<asp:LinkButton CssClass="btn" ID="bSignIn" runat="server" Text="Sign In" OnClick="bSignIn_Click" />
The event "bSignin_Click" never gets fired when I have ction="http://external.url" set on the form tag. However when I remove the action, it works as expected. I thought for runat='server' forms, the form would always post back? I need to read the URL from the action attrib and then redirect to it with some hidden input values also in the page.
After deploying a ASP.NET WebForms application to a production server some of the ajax calls has stopped working for me. After some debugging I found out that the following statement (in the internal client-method WebForm_DoCallback) was causing the problem:
xmlRequest.open("POST", action, true);
The problem seemed to be that the action-variable was empty so after checking the rendered html I found out that the form-tag rendered on the production server looks like:
<form method="post" action="" id="Form1">
However, on my developer machine I get the following:
<form method="post" action="default.aspx" id="Form1">
So, why would the action-attibute render on my dev.machine but not on the production server? This seems to be the case only for one specific web form, when I look on other pages the action-attribute renders correctly.
Is it possible to change the CSS class of the validated control if it's not valid without codebehind or just with less code ex. Set automatic CSS class to "invalid" of all textboxes which have a required field validator? I don't like to make a check for each validator (isvalid) I have, manually.
View 1 RepliesHow can I create an instance of a web control at runtime using reflection? I created a series of controls that implement a common interface and I would like to create these controls based on the name of the control which is stored in my database.
I have attempted (and failed) to create an instance of these controls using Activator.CreateInstance in the following ways:
Activator.CreateInstance("MyUserControl")
and
Activator.CreateInstance("ASP","controls_myusercontrol_ascx")
...and both return null.
I've also attempted to simply get the type of the control by trying..
Type t = Type.GetType("controls_myusercontrol_ascx");
and
Type t = Type.GetType("MyUserControl");
...and it returns null.
If I explicitly declare an object as controls_myusercontrol_ascx or MyUserControl, there is no issue -- but it can't be found with reflection.
Is it possible to create web user controls using reflection at run time? If so, how can I?
I was having issues with a gridview and CSS so I posted my question here and received a wonderful answer which lead me to implementing CSS Friendly Adapters for all of my gridviews.I have a table nested in the EditItemTemplate that holds the textbox and the button for a calendar control where I want them, it inherits the CSS applied from the CSS Friendly Adapters. I don't want it to change the CSS so I have changed the CSS inline, with no success. More importantly...
I also have a Ajax calendarExtender control to change the date for that field. When the popup is displayed the table in which the calendar is shown in also inherits the CSS Friendly Adapters code. I have tried fixing this by creating a external css sheet for the calendarExtender's cssClass property and a blending of CSS occurs where the items not specified by the Friendly Adapter Code are set correctly by the calendar.css file that I created.Is there anything that I can do to force the tables inside of the gridview to ignore the inherited Friendly Adapter Code?
I have the following code:
<object runat="server" id="test1" type="application/x-shockwave-flash" width="2000" height="1000">
<param name="movie" value="Finance/Averdaf.swf" />
<param name="quality" value="high" />
</object>
when running the above asp.net gives an error saying An object tag must contain a Class, ClassID or ProgID attribute. What can I do about this? I need to access the object from code behind because I might change the value path to something else at runtime.
is it possible to change attribute values on a non-asp.net controls (like an image)? I can change attributes on buttons and the like, but not on images? btnID.Style.Add("display", "inline") This works for a btn, but if I try to use this code to reference image (or even just try to make the image disappear) - it does not work Further info: I am using this code on a drop down list - basically when the user makes a selection i want to remove an image (make it invisible or visible) or change its display attribute (e.g. to inline). It does work ok for a real btn - but i can't reference an image ID.
