MVC :: How Can Add A Plugin Or Similar To Retrieve The Data Across Every Controller
Mar 18, 2010
ASP.NET MVC 2 and the display of commonly used data.Let's say for example, I wanted to have a listing of "Latest News" items on the right hand of my web page. Back in the day, I would made a user control called NewsList.ascx, put some DB data retrieval code in the code-behind and drop the user control intoI would like to do the same thing, but using MVC. Obviously, I don't want to place DB retrieval code into every controller to retrieve news items for the ViewData.How could I add a "Plugin?" or similar to retrieve the data across EVERY controller?
Is there a plugin that can group data and present it in a tiled format? I'd like to implement JQuery in place of the .NET Listviews that I am currently using. My current Listviews dynamically group three fields per div, with each div presented in two columns by three rows with paging.
I've looked at many plugins through numerous Google searches, and have yet to find one.
I am calling a Controller Action from a view, within that controller I need to invoke another Action which I will invoke to save the view to a network location as either HTML or Image.
How do I retrieve the URL to an Action from within a Controller. I need the actual URL, this means RedirectionToAction or View() wont work.
Why? I need to pass in a URL which will contain a call to a View. This view will be used to generate an image or HTML document using the System.Windows.Forms.WebBrowser.
.NET 3.5; C#; MVC 1;
I could do something like this, but its dirty ... well it leaves me with that dirty feeling.
I am having a form in a view page that looks as below:
[Code]...
Now when the form is posted, I am trying to retrieve the values submitted in the controller as below:
[Code]...
The string value shows null when I submit the form by checking some checkboxes. Is this the way to retrieve the values or am I doing something wrong? And I cannot use html control because all other controls on the form are server controls and I am not sure if I can only make this control a html control. And I am not sure how can I bind the values to it?
I have class LoginController, the action login and it run okie:
[Code]....
And on control LoginUserControl that inherits Logon model, I get cookie then login action, but while i debugging, it's cookie is null though login is success.
[Code]....
[Code]....
[Code]....
[Code]....
But variable userName always null, Although I add cookie,
I want to know url of View from another controller. The following is structure
Controller
Home
Account
View
HomeIndex.aspx
AccountLogin.aspx
Now, I want to goto Index view of controller Home from view Login of controller Account
I know I can use method this.RediectToAction("Index", "Home") to do it but I don't want to method. It will fail to redirect when view or controller renamed.
may I ask one seemingly simple question - I have a Javascript function that loops through my checkboxes(they're plain HTML checkboxes, not using the helper methods), and for every checked one it's adding its value to an array. So now, how do I get this array in my controller so that I can assign its values to the fields, i.e. object's properties?
This is my checkbox code:
[Code]....
and the script:
[Code]....
and here's the controller code:
[Code]....
Now, this langID should be assigned every checked checkbox's value, so I guess I'm missing a loop here too, it should go until some border that's gotten from the client script or something, but my bigger problem is how to retrieve the posted values from the javascript, something like PHP's POST["array"]...?
This Request.Form works fine when just one checkbox is checked, but now I need it to work with several checked..
UML and Patterns: An Introduction to Object-Oriented Analysis and Design and Iterative Development, that follows the UP(Unified Process). It uses a Grasp Controller pattern to interact with domain classes by some methods like NewSale(), AddNewItemToSale() and CloseSale. In windows form, I can instantiate a object of this class in the UI and then use its methods to perform the actions. This works well in Client apps, but when I use asp.net mvc, I cannot find a way to instantiate an object (one for each user) that was always visible for a Controller (MVC). I cannot insert as an attribute inside Controller because it always create a new one.
I have data coming from two tables with a foreign key relationship - one User table containing users of the web application, and one Page table containing details about pages visited by each user.I would like to be able to view these data in a gridview or the like on a page. It's easy enough to just show the User table data like so (I'm using the Entity Framework and LINQ):
[Code]....
But how can I show the Page details? I'm not bent on any particular way of showing it, but the only idea I've been able to come up with is to have a dropdown list for each user in a column. But I can't figure out how to get the page data into such a dropdown list. The tables are associated with the primary/foreign key UserID.The closest I've come to finding something similar to this is this for Linq2SQL: http://weblogs.asp.net/scottgu/archive/2007/07/16/linq-to-sql-part-5-binding-ui-using-the-asp-linqdatasource-control.aspx , and this using more traditional data access: ttp://www.highoncoding.com/Articles/169_DropDownList_Inside_GridView__Method_1_.aspx . Either way, regardless of data access technology, I can't relate these solutions to my example and get it to work
want to know the purpose of Report ViewerIs the Report View is similar to the gridview?In my dozens of webpages I have used gridview so is it better to replace the gridviews by Report Viewer?ow to use Report Viewer if I have datatables or is this similar to use the way that we uses objectdatasource to gridview?I couldnot find any video lecture about Report Viewer in asp.net official website.
I'm using a SqlDataAdapter to return search results produced by ddlsearch.selectedvalue and txtsearch.text. The results are returned to a DataTable which is bound to gridview MySearch.
Here's the code I'm working with:
[Code]....
This works great for Exact matches. However, I need to modify the above code so that it will find similar matches also. If I enter screw I need to return all results that have screw in the search field, beginning middle or end.
I think I am struggling with something that may not be entirely relevant to XPath, but this is the function I am trying to use. I have a code snippet here that works,
[Code]....
It prints out: Items for page 1 is: 1 to 10. What have I missed here regarding this issue?
I was requested to develop a GridView like screen to allow easy DataEntry without the need to Click Save/Submit on each row of the GridView.
In other words, the user wants to edit the GridView Cells in a Web Screen as if he is editing Cells in MS Excel. The Data should be saved as soon as he will exit the cell by pressing the down arrow.
It think the only way to do that is to use Ajax technology, right ?
We're thinking of making use of the Facebook Live Stream social plugin for our site (example here), but I wanted to know if it was possible to access this data via the Graph API?
I'm writing new section to a website and am looking to use a UI similar to the MSDN Download page with the Product Details and Keys in an accordian like section. Haven't been able to find a description of how this is done as of yet - still looking though but figured I'd ask if there is an available control or a description of that control instead of reinventing it.
I was wondering is there anyway to create a flag column similar to outlook or is there any 3rd party control out there that already has this feature built in?
my MVC2 delete and only my delete controller is refusing to return any class information. Its really similar to my edit function and the views are all auto-generated so I don't see the problem.
Function Delete(ByVal id As Integer) As ActionResult
I have a simple model where a Person has Gifts. I have a view which is a list of Gifts belonging to one Person.
My problem is with the Create action for a new Gift. I want it to default to the PersonID that we are already viewing the list of Gifts for. I tried simply passing the last PersonID (they are all the same)
Html.ActionLink("Create New", "Create", new { id = Model.Last().PersonID }) which works fine if there is already at least one Gift for that person but if this is the first Gift I don't have a value.
My Gift List controller knows the PersonID I want to pass but the view doesn't.
How do I pass this PersonID from my Gift List controller to my Gift Create controller via the Gift List view? Or is there a better way to do this?
I have a filter on my MVC web site. I display some records in a few different controller actions but when moving from one action to another I want to apply those filter values.
How can I persist values from controller to controller?
Should I use Session? TempData?
I am using Structure Map for IOC.
Maybe I could have a class that contains a Property for each Session Value that I use in my application and inject it on the controllers that need session?
I am working on a project in which i have a master Gridview. It has a DetailsView and two GridViews as its children. I want to have the same master and child combination on two more pages in the application. On the first page i just want to change the select command of the master gridview and everything else remails the same. On the second page i want to change the master gridview to a dropdownlist with the same datasource and everything else remains the same.Can anyone please suggest me what would be the best way to go around it. Right now, all these three pages has its own set of codes and if i do any change to one of them then i have to do it in all three pages. I was looking at usercontrols but i think those won't work since i have do to slight modifications(as suggested above).
