Below is some code. The save() method was pre-existing. I added the saveRanking() method. When I walk through the code, it hits the method, but then it just bails out of it. No exception (that I can see). Do I need that function(data) part?
Code:
function save() {

I have created a web aplication in the following environment Visual studio 2008, IIS 5.0 & OS:Windows XP. It is working fine in my local system. But when I host this application on the server some of the AJAX methods are not working.
The server environment: They have installed Microsoft .Net framework 3.5, IIS 7.0 & OS:Vista.
I am using a text box in that application. When a user types any character say 'a' a div will be opened below the text box displaying all the cities starting with the character 'a'.
for example this is code where I have written the Ajax method
[Code]....
I am calling this Ajax method in the source file through javascript, below is the code
[Code]....
The ajax method which was written in the .cs file returns the response.value correctly in my local system.But in the server the Ajax method is not returning the response.value.
Old school coders are used to having every server control create events in the .cs files.. for example.. Getting the Initial load of data, Saving Data, Deleting data... and then binding datasources to the server control..
New school coders want to do it in Jquery + AJAX calls to .svc files... That gives automatic no post backs so that is a advantage... and I think its a different way of thinking.. All of a sudden the UI related events are all being done in Jquery..
What is the most modern and efficient way to go ? How can I convince the old school coders to let us you this new paradigm ? (assuming it is the better way)
I am using a detailsview control in my form and I want to use the Ajax calendar extender control with some of the fields.
After I have connected the textboxes to the extender and when I click on them there is no calendar displayed.
If this makes any difference I am containing the detailsview in a regular panel control which I make visible through a button click.
Here is the code for the detailsview:

I am trying to get my code working as per the instruction on [URL]

Public Class PredicateWrapper(Of T, A)
Private _argument As A
Private _wrapperDelegate As PredicateWrapperDelegate(Of T, A)

ByVal wrapperDelegate As PredicateWrapperDelegate(Of T, A))
_argument = argument
_wrapperDelegate = wrapperDelegate
End Sub

Return _wrapperDelegate(item, _argument)
End Function
Public Shared Widening Operator CType( _
ByVal wrapper As PredicateWrapper(Of T, A)) _
As Predicate(Of T)
Return New Predicate(Of T)(AddressOf wrapper.InnerPredicate)
End Operator
End Class
Then I have the function which I have modified to use my department id variable (did)
Function DidMatch(ByVal item As ListDataItem, ByVal did As Integer) As Boolean
Return item.AssigneddepartmentID.Equals(did)
End Function
Then I try to call it from my code:
Dim children As List(Of String) = toplevel.FindAll(New PredicateWrapper(Of Integer, Integer)(Did, AddressOf DidMatch))
I then get an error on DidMatch ... Error Method 'Public Function DidMatch(item As DeptMenuData, did As Integer) As Boolean' does not have a signature compatible with delegate 'Delegate Function PredicateWrapperDelegate(Of Integer, Integer)(item As Integer, argument As Integer) As Boolean'.
when I upgraded my root website from ASP.NET MVC 3 Preview 1 to the new Beta 1. I am using RavenDB, which needs to run as a virtual sub-application with Windows authentication instead of Forms authentication. I had raven working like described above just fine in preview 1, but with beta 1, now it won't work. It looks like no matter what I try, the membership provider system for my root website is redirecting me back to the login page, even though I've set my RavenDB virtual directory to use windows authentication and cleared out the membership and roles providers in it's web.config. I guess MS changed something to do with
either routing or authentication between preview 1 and beta 1. If anyone else sees this problem and knows how to fix it, I would be in your debt. I would guess that the easiest way to recreate the problem would be to create a new ASP.NET MVC 3 Beta 1 root website, then add a virtual directory marked as an application. See if you can get the root site to use the forms auth provided by default, but have the virtual directory use windows auth, denying all users but a specific one of your choosing. I can't seem to get this scenario working in the beta like I did in the preview.
I have an ASMX Web Service set up to use the HTTP GET method. Simple methods which take basic String and Int parameters are working ok, and I can call MyService.asmx/MethodName?Param=Value and get a response back in XML.
However, when I have a method which has a nullable Int (i.e. int?), I get this error:
< Method Name > Web Service method name is not valid.
The error message is confusing, as the method does exist, just not in the GET scope. I presume this is because a nullable type is too complex to be passed via the URL, but I can't find any documentation or SO posts on this.
I appreciate that complex types like Lists or custom classes etc will not work using GET, but I would have assumed that a simple nullable int or nullable datetime could be handled natively, simply by detecting whether it was omitted from the URL. Guess it's not that simple!
I wrote some code to connect the application to it's database, then I created some code to use the connection code and retrieve, update or add some values to the database, Also I might have some code to deal with other stuff than to deal with the database
The code is a little complicated, maybe it's simple but it's not short, for example to write a good piece of code to just retrieve a single value so I could set the controller with this value I used this :
SqlConnection sqlconnection= new SqlConnection(ConfigurationManager.ConnectionStrings["DefConnectionString"].ConnectionString);
SqlCommand sqlcommand = new SqlCommand("SELECT name FROM message WHERE id = 3", sqlconnection);
try
{
sqlconnection.Open();
lbl_name.Text = (string)sqlcommand.ExecuteScalar();
Status.Text = "Done";
}
catch (Exception ex)
{
Status.Text = ex.Message;
}
finally
{
sqlconnection.Close();
}
I might even add some code to store some info in the database about any exception is thrown, I think the code is pretty basic, yet it's not small, given that it's the smallest piece I'll need, some huge code is written for adding or editing new items, and also consider that it's not the only code I'll write in the page, the page has more needs.
I've provided a detailed case I hope!...So what do you think will be the best way to make my page fast and easy to read and have an organized code I've started placing every code in an appropriate method, but some methods are common so I create them again in every page that needs them like a ConnectionToDataBase Method, and mean while I think I just organized the page so I could mainly look at Page_Load and see what are the called methods and then scroll down to read the definition but It's still a big page and note the best practice I think
Sorry for all the big question, I just provide details so I could get a reasonable answer for my question, I hope everyone benefits from it as most questions are pretty basic, newbies like me needs some detailed cases and answers to get a better start.
EDIT: I know I'm new, So any comments on my code are more than welcome!
Could anyone tell me where is the best place to put my business methods when using EF4 code first POCOs? Should they go in the POCO class? E.g.
public class customer
public property Id as int32
public property Name as string
public property Archived as boolean
public sub MarkAsArchived
me.Archived = true
end sub
public function EmailAllInvoices as boolean
...
end function
end class
Or should the POCO class be as clean as possible and a seperate class be used for business logic which accepts an instance of a customer POCO in the constructor to work on?
yes client side must be java script but my qustion is not that.i am asking that can i use c# language to implement "actions" fired on "click side events" such as mouse over the reason for this question is that i remember some syntax of registering functions for particular events of formview, which are call when the event occurs (yes there ispostback involved" is something like the above possible for client side events using c# or even vb.net
protected void Page_Load(object sender, EventArgs e)
{
Label3.Text = "this is label three";
Label3.Attributes.Add("OnMouseOver", "testmouseover()");
}
protected void testmouseover()
{
Label4.Text = "this is label 4 mouse is working!!";
}
is there any tools within VS2008 or Free 3rd Party tools where i can generate a Diagram of Class Methods and Code Behind events. think of the Table Diagram of SQL, it will show all fields, Primary Keys and to what table it is connected via foreign keys, etc.That is what i wish to make, in a much faster way, where it will show all class and within it is all the methods then linking them are the Code behinds and the event where the class is called.

I have an extension method as follows:
public static class PageExtensions

public static int GetUserId(this Page targetPage)
{
var user = Membership.GetUser(targetPage.User.Identity.Name);
return (int)user.ProviderUserKey;

Now in a page I need to use this method in a static WebMethod, so I have added another 'extension method' to PageExtensions:
public static int GetUserId()
{
return (int)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey;
}
and I call it as follows in my WebMethod: PageExtensions.GetUserId()

I am trying to use some page methods on an aspx page. I've done this several times before in other asp.net applications and never had issues until now. I believe that maybe the issue has something to do with the methods be exposed to POST but I'm not entirely sure. Everything on the page loads correctly then once it attempts to make an ajax call rather than hitting the "test" function, the page tries to reload and the page_load method is called again. I chacked the URL string on both cases when page_load is called and both are correct. I am suspicous that there is some need to do with the web.config but I'm not sure what. The application is close to 10 years old and has been grandfathered up all the way to ASP.net 3.5. On another note, I can hit asmx functions perfectly fine its only page methods that seem not to work.

I found a write-up somewhere about the multi-handle slider control and in the post there were the following javascript lines:
slider.add_value(value);
slider.add_drag(value);
Slider, in this case, is my slider control... but how did the person know these two methods exists? Is there an API guide somewhere for the Ajax Control Toolkit?

View 5 RepliesScenario is, I have a tab container inside which I placed 5 tabs and each tab having 4 Cascaded dropDown.Now for changing the tab page everytime refreshed and calling all 5 parent control dropwdown to fill.But can I prevent it in that manner so that for changing the tab only that parent webmethods will be called to populate.In page load itself it will call only the active tab parent Cascading dropdown web method.
View 8 RepliesI am showing state,city, zipcode in cascaded format. I designed cascade dropdown with asp dropdown list controls. I am loaing the citys & zipcode based on selection index changed.. here when I am selecting city the request is sending to server & its loading citys....
I don't want see post back operation on my page when I am selecting city & zipcode. So I am thinking to use Ajax cascade dropdown list to avoid sending the request for each selection.
If I use Ajax Cascade dropdownlist can i cascade the loading of citys & zipcode without using webservices?
If I use only webmethods for cascade dropdown it will work ?
