I am using ASP.NET MVC2 for my project. I want to send the user confirmation messages after actions.
Ideally: User clicks on a link with a query string (i.e. a link to delete an entry) The controller does what the link says, creates the success message, and uses RedirectToAction to get rid of the query string from the URL. The new action displays the success message.
How to manage user messages to avoid hardcoding messages accross the web application.

And Question: I want to select brands (multiple checkboxes) of product manufacturer on Select page and show list of products on Show page. But i can't understand how to pass data (wich checkboxes is selected) from one page to another
View 10 RepliesFor error messages, validation faults etc you have
ModelState.AddErrorMessage("Fool!");
But, where do you put success responses like "You successfully transfered alot of money to your ex." + "Your balance is now zero". I still want to set it at the controller level and preferably in key-value way, the same way as errormessages but without invalidating the modelstate.
i have a problem there that i had an application that is running now i have problem that i have to send messages to all my user that are in my list.

View 2 RepliesIn my ASP.NET MVC application, I do not want to report all exception messages to the user. But there are certain types of exceptions that I'd like to report to the user, so I created an action filter to decide if it's this particular type of exception, and if so then display the exception's message, otherwise display a generic message. So I created a custom exception called ClientException.
My filter looks something like this:
if (filterContext.Exception is ClientException)
message = filterContext.Exception.Message.Replace("
", " ").Replace("
", " ");
else
message = "An error occured while attemting to perform the last action. Sorry for the inconvenience.";
filterContext.HttpContext.Response.Status = "500 " + message;
I read this http://blogs.msdn.com/b/kcwalina/archive/2007/01/30/exceptionhierarchies.aspx where the author recommends using existing .NET exception types to report usage errors. However, by introducing my custom exception, I just have to do a single check in my filter.
I am getting two identical errors message when I view my Web page in my browser:
Valid User Session Variable Not Found: System.NullReferenceException for this line:
Code:
Response.Write(Session("ValidUser").ToString & "<br />") <----------
and the same error for this line:
Code:
Response.Write(Session("strEmail").ToString) <-----------
This is the code in that page:
Code:
Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
Try
Response.Write(Session("ValidUser").ToString & "<br />")
Catch ex As System.Exception
Response.Write("Valid User Session Variable Not Found: " & ex.ToString & "<br />")
End Try
[Code] .....
This the page that users are redirected to after logging on and, after verifying their credentials at the log-on stage, should show 'Hello DonaldDuck@Disney.com, Welcome to my website'.
Do these errors mean that the user cannot be validated in the database?

View 1 RepliesI am writing what i will call a survey system. The surveys will consist of a series of questions, split into sections. The survey definitions will be stored in a database. The questions can be of various types, that have different input methods and validation (e.g.textbox, numeric textbox, selectlist etc.) I am creating a set of user controls that map to different question types. I would like to completely abstract the survey rendering logic from the, survey definition logic. The way i thought i would do this is to use a dumb rendering control that simply takes a collection of controls and renders them out in a for each loop a super simplified version of what I am doing.
private void RenderControls()
{
foreach (UserControl CurrentControl in this.ControlsToRender)
{
MyPlaceholder.Controls.Add(CurrentControl)
}
}
This works in the sense that the correct controls get added to the place holder,however nothing renders. Presumably this is because it does not have the markup in the asxc file.
If i do something like this
private void RenderControls()
{
foreach (UserControl CurrentControl in this.ControlsToRender)
{
MyPlaceholder.Controls.Add(this.LoadControl("path to ascx file")
}
}
It will create the correct number of controls, but i don't want to instantiate the controls here because i would need to to set various properties based on cconditional logic i want to abstract away from this pure rendering layer.
what i want to do is instantiate the controls else where, set the relevant properties and then simply pass a collection of these into the rendering control to render out.
Is there a way to do this with user controls? Would i have to create custom controls instead?
I've implemented a custom ASP.net membership provider to deal with forms authentication. The custom provider uses a custom User object for authentication and authorization. I was wondering If I can pass this object to each WCF call without adding it to the parameters list?

I have two websites both of which will share the same users in a SQL DB for membership. The first site is the standard site while the other is a subdomain for admins.
If the admin logs onto the either site, I don't want that person to have to re log on to either site if he/she is sent there via navigation. To the user it would just seem like one site. Because user would be using same session, if they log off either site they would have to reauthenticate.
How would I go about passing this information?
Again, I am wondering why there is no one asking this kind of question. And may be my idea is wrong. Let's see the code:
<uc1:drilldown ID="drilldown1" runat="server" sType="F.W" rID='<%=request.querystring("r") %>' />
After it passed into my property in user control, the value is <%=request.querystring("r") %>
It is absolutely not reading my function!!
I have a user control that contains a reportviewer control.And I want to send an array of reportparameter to my user control.But I can't figure out how to do.I'm getting "Object reference not set to an instance of an object.

ReportParameter[] parameters = new ReportParameter[4];//parameter number can be different
parameters[0] = new ReportParameter("imza", imzalayacaklar);
parameters[1] = new ReportParameter("Sayi_Son_Eki", "984");

I have a page that contains a few user controls which all use an id in a querystring. I want to change this so that the page can send the id to the user control and can call a function on the user control.
Also is it possible for the user control to get the id from the page or a control on the page as its parent?
I have one ASP.Net web page dynamically loading any one of about twenty User Controls at a given time. Since each user control is somewhat different, I've implemented the following extension to me pass a variable number of parameters to custom user control constructors: [URL]It, by the way, works very well! However, I've now come across the fact that both the web page and the user controls will need to share a few Data Tables. In other words, both the web page and the user control will need to access and manipulate data in these data tables.
To implement this fact I've used the Session object to store each data table. Each of these data tables starts out empty and then starts growing as the user enters more data into the user controls. The initialization of the data tables has to be done in the web page for a series of technical reasons that I won't get into here but rest assured that it does have to occur there.
But I found that in order to ENSURE that the initialization was taking place, it was simplest to just pass a reference to each data table as an extra parameter in the LoadUserControl call. This does work but it seems like overkill to me because on the user control constructor side, nothing is actually done with the data tables at the time of instantiation of the user control.
This made me go back to basics, thinking, "Why include a parameter if you're not actually going to use it?" But yet, it does seem to be the most straightforward way to ensure the data table is initialized and stored in the Session object.
I have a shared module in an asp.net web app which gets various information about a group or user. Since the Iuser account on the web does not have enough rights to query the AD, I need to supply an appropriate userid and passcode for the directoryentry in the shared code. Since my credentials so the have the appropriate rights to query the AD I like to impersonate myself(user.identity). This works fine for a webpage, but I can't pass the user.identity object to shared code. I get an error. Is there a way to pass the user.identity object to a shared function in another module?

what may be the cause. it woks fine from C# code behind.
