I'm in a .NET environment and when a user performs a save or update action, Foundation pops up a status message 'processing...' or 'saving...' or 'refreshing...', then 'saved.' After a given amount of time, the message will disappear,sometimes before the given action is really complete. How can I access this functionality and extend the time these status messages appear on the screen?
View 1 RepliesI am getting an exception that child actions are not allowed to perform redirect actions. Although I can understand that this might is true in most situations I do believe that the framework might allow this to pass when a Child Action is calling another child action like in this example:
I have this code in my CountryController (I compacted it a bit but the main concept remains that I have a controller with Child Actions only):
[Code]....
This exception is being thrown:
Server Error in '/' Application.
Child actions are not allowed to perform redirect actions. Description:An unhandled exception occurred during the execution of the current web request. Review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.InvalidOperationException: Child actions are not allowed to perform redirect actions.
I'm working on a MVC3 application and I created my POCO classes from my database with the DbContext Code Generator. All goes fine until I got stuck in this situation. Note that I use the repository pattern and I use for every entity a dedicated repository that every get a new instance of the DbContext.
Now, I'm in this situation:
object A has a relation one-to-many with B (A can have one or many B)
object B has a relation many-to-one with C (C can have one or many B)
object B has a relation many-to-one with D (D can have one or many B)
I should add a new object B, consider that object C and D are yet existing, so I must only do the relation and the object A can be created or updated. In the specific consider that A is customer and B is subscriptions (C and D are virtual objects properties
in the B).Now If I try to save I got duplicates in C and D tables, while the management of the object seems to work.
Here's the code: [Code]....
And here the add and the save method of the customer repository: [Code]....
Should I check for every relation and modify the state of the entry to Unchanged or something like that ?
I have and Article object that I update in my controller.... the object is passed into the controller and then I just call UpdateModel(inArticle) and it was all good. I now expanded my article to belong to a category and want to do that update there as well. I am not sure if it was the right thing to do but just as a start i hard-coded an update to the ArticleCategory table, just after I do the UpdateModel. This works but I am not sure how to code this update?
I am using the repository patter and i somehow feel that I should be passing an Article and an ArticleCategory object from the view to the controller? While I was writing this I thought that I could just extend my article object to include the categoryID but what if I really wanted to pass two un-related objects from the view to the controller? The UpdateModel persistes the database objects as by VoodooMagic, how would it work if I wanted to update 2 un-related objects?
I used to ADO.NET+DataSet many years ago, but now, I need it again. So what I need is to add related rows with tableAdapter.Update method.Here is my code: [Code]....
but I get the "The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Question_Project". The conflict occurred in database "QTracker", table "dbo.Project", column 'ID'. The statement has been terminated." exception at the "qTA.Update(ds);" row. I have seen many examples that do the same, but my code still throws the exception.
I would like to update new records that get inserted in DataSet to Sql Server Database. Below is a working example of how to do this if you use "DataAdapter.Fill(ds)".
But i don't want to fill data, becouse i don't need data, i only need shema (I will use this dataset to insert new data to Sql), so i would like to use "DataAdapter.FillSchema(ds)"
[Code]....
I have a problem in getting my gridview to update. The datasource gets its data from 2 related tables using the following select statement:
SELECT StudentSubject.StudentID, Students.[1stName], Students.Surname, Students.Grade, StudentSubject.Subject, StudentSubject.GradeOverall, StudentSubject.ReportYear, StudentSubject.ReportSession, StudentSubject.Criteria1Grade, StudentSubject.Criteria2Grade,
StudentSubject.Criteria3Grade, StudentSubject.Criteria4Grade, StudentSubject.Criteria5Grade, StudentSubject.Criteria6Grade, StudentSubject.Criteria7Grade, StudentSubject.Criteria8Grade, StudentSubject.Criteria9Grade, StudentSubject.Criteria10Grade, StudentSubject.Comment
FROM (Students INNER JOIN StudentSubject ON Students.StudentID = StudentSubject.StudentID)
WHERE (StudentSubject.Subject = ?) AND (StudentSubject.ReportYear = ?) AND (Students.Grade = ?) AND (StudentSubject.ReportSession = ?)
The ? stem from combo box controls which I use to filter the results So far so good!
However, when I try to update the data in just one of the tables, nothing happens, no error, just no update. The update statement I'm using is:
UPDATE StudentSubject SET GradeOverall = ?, Criteria1Grade = ?, Criteria8Grade = ?, Criteria7Grade = ?, Criteria6Grade = ?, Criteria5Grade = ?, Criteria4Grade = ?, Criteria3Grade = ?, Criteria2Grade = ?, Criteria9Grade = ?, Criteria10Grade = ?, Comment =?
WHERE (StudentID = ?) AND (Subject = ?) AND (ReportYear = ?) AND (ReportSession = ?)
I've tried this with a similar setup with just on table and it works fine.

How to manage user messages to avoid hardcoding messages accross the web application.
View 17 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.
Lets say i have a button control on a page and a label control. On clicking this button it performs series of actions say Action 1 , Action 2. Action 20 which will take say approx 1 hour to complete. What i need is, once this long processing is started, My web page should show the status of each action on label. Eg. After clicking a button, Label1 text should be "Action 1 is started" after Action1 is completed and Action 2 is started ,.... Label1 text should be "Action 1 Done...Action 2 started" I need this so that my user can see whats the current state of processing.

View 2 RepliesI need to update the status in Twitter in asp.net.I need to use Twitter API to achieve this.
View 1 RepliesI have tried the demo and the code example and it did not work. I was reading that some of the Twitter request uri's have changed and that some are not in use anymore, not sure what that means.
When I run the code it authenticates but when I post I get a 404 error on the Tweet_Click on this line - twitter.Tweet(txtTweet.Text)
On the demo it does not do anything when the button is pressed, the page only refreshes.
For an MVC 2 app that relies on many partial views and almost exclusively uses Ajax for POSTs/GETs, what would be the best way to implement the setting, passing, retrieval and display (using a JavaScript modal) of these messages?
My forms all POST (by way of jQuery $.ajax) to actions that return partial views (html) that are used to update a in the "success:" part of the $.ajax function.
I was hoping for some sort of mechanism in the master view that could "listen" for any messages that any of these partial views might be "delivering"--through their ViewData, for instance.

I'm writing an HTTP handler in ASP.NET 4.0 and IIS7 and I need to generate a file-not-found condition.
I copied the following code from Mathew McDonald's new book, Pro ASP.Net 4 in C# 2010. (The response variable is an instance of the current HttpResponse.)
response.Status = "File not found";
response.StatusCode = 404;
However, I found that the first line generates the run-time error HTTP status string is not valid.
If, instead of the lines above, I use the following:
response.Status = "404 Not found";
Then everything seems to work fine. In fact, I even see that response.StatusCode is set to 404 automatically.
My problem is that I don't want this to fail on the production server. So I'd feel much better if I could understand the "correct" way to accomplish this. Why did the first approach work for Mathew McDonald but not for me? And is the second approach always going to be reliable?
