I want to create a page with a stopwatch. I have a start button and I have a starttime in my model. Now I want to display the running timer in my view and it should reflect the starttime from my model. How do I update the timer with my starttime from my view right after I have pressed the startbutton, and how do I get it to update each second? Do I need to use jQuery for the update?

There is a gridview in my website pulling data from sqlserver2005 . Now i want to update my website after every 5 min so that it can pull fresh data from sql. I know the basic idea that it can be done by using timer. But i don't know how to implement it?
View 5 RepliesGOAL: on a web page (vb.net) content in a placeholder will refresh with a different .ascx (user control) every 30 seconds (rotating 3 in total) and of course i dont want to refresh the whole page, just the placeholder.
I'm new at AJAX (that's my first problem - lol)
I set the timer up to call a function, but not sure how to go about refreshing the placeholder with a different ascx file. I'm sure i'll be using UpdatePanel to do this, but haven't been able to figure this out. Easy to replace a value in a label using AsyncPostBack trigger, but nothing on how to achieve this.
I m facing problem updating a method which shows the count on master page. That method is bind to treeview control.Whenever a data is saved count is incremented to one. but method gets refreshed only when there is a postback. I want it to be updated after every few seconds or whenver there is data saved. there is pretty gud solution with custom ajax that is with json. But that is not possible with exiting solution.i have to redesign the complete treeview structure in html. And with timer control of ajax whole page gets refreshed.
View 2 Replies"When a partial view is instantiated, it gets its own copy of the ViewDataDictionary object that is available to the parent view. The partial view therefore has access to the data of the parent view. However, if the partial view updates the data, those updates affect only the partial view's ViewData object. The parent view's data is not changed."Is there a common way around this? For instance I have a View containing two Partial Views (User Controls) that source the same data from the Parents ViewData. The first Partial View is able to update (add/delete) certain data from the Parents View Data, however the second Partial View sources the same data but obviously isn't reflecting the changes owing to the above MSDN statement.
View 4 RepliesVS2010 ( Vb.net ).I have a masterpage that contains a gridview, giving stats and information on client files sent to us. This gridview is updated by means of a timer control every 10 seconds. In my grid I have an image field, to display either a tick .. if everything is ok or a cross for any problems.When the timer control timer event forces a gridview databind every 10 seconds.When the page first loads, i get the default red Cross in the gridview imagefield, however when the timer loops forces a 'databind' I lose the redCross and it is replaced with the default image control ( as if no url is set ) . Then I get a server 404 error.I am using the OnDataBound event to fire my vb sub. I have commented out evertything just to get a solid starting point but im still getting errors.

I'm searching for an example with an client timer that ticks synchronous with an server timer. Also there must be a button on the client side which can reset the server timer to an default value, and with this it also resets the client timer ofcourse. I tried it myself but it seems that there is some postback delay which makes it impossible for me to make it atleast look like it goes synchronous.
I hope somebody got an example for me, the button part is really important because by pressing that button the delay comes.
I have a view that is based on a view model. This model has a single property called Entity, of type ServiceProvider, which is a Linq2SQL object. This object has relationships to 2 other objects Address and ServiceProviderGroup. In a HTML view I have textboxes that allow the properties of the Entity property to be changed and also the properties of the Address object related to it.
E.g: ViewModel.Entity.Code, ViewModel.Entity.Name, ViewModel.Entity.Address.City, etc, etc.
There is also a selectlist that will allow the Entity.GroupId (int) property to be changed. This defines a relationship to the ServiceProviderGroup class which is also accessible via a Group propery. (standard linq2sql back references)
The Edit[Post] method accepts an instance of this view model and all properties (on the Entity, Entity.Address properties) are set as expected. I then lookup the original object in the database and I also bring back the original address and group data.
E.G: entity => entity.Code == viewModel.Code && entity.Address.Id == viewModel.Address.Id && entity.Group.Id == viewModel.Entity.GroupId (I'm not looking at the code, but it's something similar to this)
Either way the original Entity, Entity.Address, etc, come back from the database. I then apply the changes from the view model to the original object using UpdateModel and everything is updated as expected. But, if I try to change Entity.GroupId, i.e. change the relationship on the entity to another ServiceGroupProvider object, I get an exception in the generated code of the ServiceProvider object.
This happens in the GroupId property of the ServiceProvider class (viewModel.Entity). When it reaches the line if(!this.HasLoadedOrAssignedValue) it enters the "if" statement and throws an exception. When the data is first read from the database it skips this part. But, when UpdateModel attempts to apply the new Entity.GroupId value it throws the exception.
This works in IE8 on my local machine (of course), and works on FireFox on the server, but in IE the content doesn't update unless I manually refresh the View. Here's the code:
[Code]....
So it's just some jQuery that replaces the body html with the PartialView data. As I said, this works locally no matter what, and works with FireFox from the server. I'm not sure why the content isn't updating in IE. The code is running correctly and returning the View as expected. I even slapped the cache: false on the jQuery GET so I didn't run into that delightful problem. why the MVC View isn't updating in IE?

where c.CustomerID == "ABCD"
select c).Single();
customer.Country = "Canada";

How to Print the SQL statement being sent to database server by the above Linq Query?
EDIT: This question is vague and will likely be of little use to anyone. I am awarding internet monies to the gentleman below whom "helped" me.Sorry that the title is a little vague. I am still new to asp mvc & EF. Here is my issue. I have a DB somewhat like this.
Employee
- ID
- Name
- Address
EmployeeJob
- EmployeeID
- JobID
- StartDate
JobTypes
- ID
- JobName
I want a create form that will show all the Employee fields as well as a list of JobTypes for the users to be able to select. Then I will post the results back to the controller and update the DB. I have started looking into custom viewmodels, but am still unsure of exactly how to put that together and get it to work.
I'm quite new to MVC, and only now i got hands-on with Ajax and Jquery as well.I've been reading a lot on blogs and forums, but can't seem to find the exact answer to my question.Here's what i want to do:1) Simple file manager View, where user can upload the file2) After successfully uploading, user is redirected to other View3) Meanwhile, the server starts processing the info existing on the file just uploaded. I want to be able to update the View the user is viewing, with the actions that are being performed on the server. Example (like stages): Reading File, Converting File, Parsing File, etc...4) When all stages are completed, i can show the user some buttons or whatever (until then, he has access to nothing...just view the page changing and processing)So....First, is this feasible?If so, how?I tried many approaches with AsyncController but can't seem to achieve nothing good.
View 1 RepliesI have a table of data from which I am trying to delete a single row using jQuery. While I am having no problems getting a POST delete to work, Iam having issues getting the partial view to update properly to reflect the deleted data.The table resides in a strongly-typed view, Errors.ascx, which is called in my Index.aspx page. Errors.ascx is nothing special, just a table where each row has a delete button that looks like this:
public ActionResult Delete(Guid id)

View 2 RepliesI had another post about this issue, but decided to modify it to drill down and find the issue. I was doing a master/details, and that was not working, so I have changed it to just a single data source with a single details view created entirely via wizards. The issue is, when I click on the auto generated edit link, and change values in the fields, after clicking update the page refreshes without error but does not update the record. Here is the code:
[Code]....
I'm new to asp.net 3.5 and I have been working through the tutorials using a real access database to learn how to use the new controls. I have an extremely simplistic page setup with a master-details view, the master using the gridview, and the detail using the detailsview controls. Everything seemingly functions correctly, except when I try to update the data in the details view. I make changes to the record, click update and the page posts back but nothing is updated in the database. No errors are given either.
View 10 RepliesI have a problem that is driving me insane. I have a simple detailsview that operates as you would expect a detailsview to do - the only difference being that in the updated event I send an email to various people to advise of detail changes (I have conditional testing to do this).
The problem is that if the user goes crazy with left clicking the update button, email recipients can receive multiple duplicate emails.
I have looked all over the net and seen many varied solutions for this problem - mainly using javascript - but none of them seem to be able to block multiple clicks without disabling or hiding the update button - which obviously causes issues with client side validation in the event that information is missing or incorrect.
article on binding to a list and I've got that working fine on one view. But what I'm stuck when doing it off a master record. Everything seems to work except that when I look in the database the detail records previous associated with the current master have their Foriegn key to master set to Null and a new set of detail records have been inserted. I've got a really simple form for this object
[Code]....
The form collection comes back with the expected prefixes:
[Code]....
And the Controller.UpdateModel(master) binds all the properties correctly. But when I call dbContext.SaveChanges it issues the follow sql from sql profiler (psuedo code)
[Code]....
I've got a work around that works but it's pretty hackish and I'm currently not matching up the keys so it's dependent on everything coming back in the right order. Plus I've got to include all the fields that I want updated.
[Code]....
I thought that entity framework's code first was the culprite but I've unit test that and it works fine. I've got a feeling that UpdateModel is somehow removing and re-adding the children. Has anyone else got this to work? Of course, I could throw in the towel and parse the indexed field names myself, but I'm so close!
So I sometimes use app_offline.htm to take an app offline while I upload a new version.However, while I am in the process of uploading larger dll's, I get the yellow error-screen saying the dll could not be loaded.This seems to be out of sync with my expectations of what app_offline.htm does (stops the app entirely), and also provides the users with errors in stead of the nice app_offline.htm I put up.Am I doing something wrong or is this behavior by design?
