AJAX :: How To Send Parameters To Custom Complex Business Object To WCF Service Using JQuery
Jul 23, 2013
I am trying to call web service from jquery..trying following way but i am not able to pass to complex type parameter to WCF service.My wcf function is as follows
<OperationContract()>
<Web.WebGet(UriTemplate:="/GetData?strErrMsg={strErrMsg}&chrErrFlg={chrErrFlg}", ResponseFormat:=WebMessageFormat.Json, BodyStyle:=WebMessageBodyStyle.Wrapped)> _
Function GetData(ByRef strErrMsg As System.Collections.Generic.List(Of String), ByRef chrErrFlg As String) As String
strErrMsg is System.Collections.Generic.List(Of String)
I am trying to call as follows
var Type;
var Url;
var Data;
var ContentType;
var DataType;
var ProcessData;
var parameters;
[code]...
And I am able to call other methods in same way having string and integer parameter.I have gone through this but didnt get anything. URL...
I am posting a Jquery Json serialized object to my controller but not all of the data is getting passed. One of the members is a complex type that is also Json serialized. This is the one that isn't getting through to the controller.
Here is the class I'm passing to my controller via Ajax post. Note the complex type, RoutingRuleModel.
SourceCodeModel.cs:
[code]....
Problem: SourceCodeModel contains correct values EXCEPT for it's complex member: RuleModel, which comes back as a RoutingRuleModel with default (null or 0's) values.
I put a break point inside MyWebMethod. When I invoke this call on the page, the break point never gets hit. It works fine when I remove all parameters from MyWebMethod's signature and pass in '{}' from JS as parameters. Once I try to pass in a string parameter, it stops working.
I´m using jQuery to make the ajax calls to web services. I´m not using json, I want the information in XML. If I don´t pass parameters and I make the WS parameter less it works but if I want to pass a value as parameter (I tried int and string) it doesn´t work. Here is my code:

The web service

The error that I get from firebug is an exception System.InvalidOperationException and it says that the parameter region_id is missing.It can´t be very difficult because it works without parameters but all the information I find in internet
I'm fairly new to .NET development so I might be missing something very simple here. I'm trying to set up a web service as a data item so that I can bind it to a control on my page. I was reading some tutorials about doing this in an earlier version which seemed very simple. All you had to do was add the web reference, create a data source and use the object type, pick the web service and enter the name of the call that would retrieve the data.
In 2008 the object data source type doesn't seem to be available anymore when creating a new item unde app_data. I get options for SQL Server, XML and XML schema. I've tried adding an existing source and picking each of the files generated for my web service reference, with no success. I suspect that I have to use one of the XML options, though at this point my web service is a simple thing that only returns some strings for prototyping purposes (I'm not the one writing the web service, just the front ends. Our other developer hasn't come up with a stub service yet). I know there must be some way to set a web service up as a business object so that you can bind it to a control like a gridview.
Have try to send the complex string that is created(serilize) from data.If I write just a regular string there is no problem but I want to sendover the array data as a string and then deserilize it does not work.What happens is that the webmethod 'save' never start. No error occurs!I suppose it is becouse the string contains a lot of " but I dont know howto change that and then bee able to deserilize it to the object.The string 'strData':
"{'JSONString': '[{"Show":false,"SortOrder":"","QuestionText":"Ingen rapport lämnas till kund då följande muntliga rapport har lämnats:","DefaultValue":"","CSS":"","Note":"","RQID":"Label","FunctionNr":0},{"Show":false,"SortOrder":"","QuestionText":"Lämnar
I've scenario where I want to insert data into database without post back. there are around 12 to 13 fields which i need to insert. I'm passing DTO from the client side which is actually Json object. Now the problem which i'm facing is how to convert that Json object which i got in webservice to the "class" (in my case class name is User) object.
[Code]....
In the above case AddNewUser method takes the object of User class. But i'm getting casting error. So how do I convert Json object to the "User" class object?
[WebMethod] [SoapHeader("_webServiceAuth")] public User GetUser(string username){ try { this._validationMethods.Validate(_webServiceAuth); User user = new User(username); [code]...
It works but when I'm trying to enter in TextBoxSearch by other language at the other side in my page load of good.aspx I'll get parameters using Request.QueryString["key"] it gives me like this "?????? ???? ????".
That's interesting when I copy and paste text into TextBoxSearch at result it works good at the Goods.aspx Pageload event.
I have two business objects mapped via LINQ to tables. One of the objects contains an instance of the other object and share a key as an identifier.I want to retrieve Class A and within class A all of Class B's values as well. What I am doing is this:
[Code]....
[Code]....
This seems a little clunky, as in slow. Is there a better way to get the Class B (User) information without making a query every time?
This is My Method, How to get Checkbox Value from Gridview and adde that value inti list? Â private List<ActivityList> PopulateData() { string ActivityCode = string.Empty; string ActivityName = string.Empty; List<ActivityList> list = (List<ActivityList>)Session["ActivityToStudent"]; List<ActivityList> listObj = (List<ActivityList>)Session["ActivityToStudent"]; for (int j = 0; j < listObj.Count; j++)
So part of my web app centers around this very important form which is used to create a form. Its like google docs form. The user keys in a type (checkbox, textfield, numericfield) and a label and slaps it into the system, and it generates a form somewhere.
Its a little more complex than google forms, the field types are complex and theres a lot more to that form (It happens to be a form generator for a finance plan)
The app is asp.net, I was thinking of using jquery and jquery's own ajax methods to post the data, but I think it would just turn into a very hairy situation, I then thought silverlight, but Ive never done silverlight before but I am an experienced .net guy.
So what do you guys think, will silverlight be too tough for a first timer for this kinda thing? Or should I stick to jquery. Plus points for silverlight is its an inhouse lan app and this particular page will be used by people with very high bandwidth.
I d like to send bulk emails as part of custom reminder service for my website (500 emails approximately).Which is the better way to send all these emails without spamming? I was thinking of sending 15-20 emails per minute, to avoid overloading mail server. Is it better to use multiple TO recipients or use BCC?The reminder service will run on a background task.
I'm designing a page which makes an ajax call (via jQuery.ajax) to a page method on the server side.On the server side, I have two classes: Agent and Channel.
In the page method, I'd like to return a List<Agent> and a List<Channel> to the client side. How can I return two lists to client side? should wrap them up in one class like:
I'm kinda new to web services and want to make sure I am doing things correctly.
I have a custom object which has sub objects as well. (let's say Company object, sub object is collection of Employee objects)
I want the web service to return a collection of Company objects. Do I make the service return a Dataset and custom generate a dataset with datatables representing the different objects?
What is the best way to do this? I tried to just serialize it, but that doesn't seem to work either.
I tried this dll
[URL]
But the output XML doesn't seem to include the sub object.
I have a custom class declared as follows (in vb.net)
<Serializable()> _ Public Class NumInfo Public n As String Public f As Integer Public fc As char() Public t As Integer Public tc As char() Private validFlag As Boolean = True Public Sub New() End Sub
I also have public properties(read/write) for all the public variables
End Class In my service.asmx codebehind class I have a webmethod as follows: <WebMethod> _ <XmlInclude(GetType(NumInfo))> Public Function ConvertTo(ByVal info As NumInfo) As String Return mbc(info) 'mbc is another function defined in my service.asmx "service" class End Function
The problem is that when I start debugging it to test it, the page that I get does not contain any fields where I could input the values for the public fields of numInfo. How do I initialise the class? There is no "Invoke" button either. All I see are soap details as below:
ConvertTo Test The test form is only available for methods with primitive types as parameters. SOAP 1.1 The following is a sample SOAP 1.1 request and response. The placeholders shown need to be replaced with actual values.

What am I doing wrong? For the record I tried replacing char() with string to see if it was the array causing problems but that didn't help either. I'm fairly new to web services. I tried replacing the custom object parameter with a primitive parameter just to check how things worked and it rendered a page with an input field and invoke button. I just can't seem to get it working with custom object.

Again, I am new to the ASP.NET world, and I come from a Windows Forms background. I'm working with an ObjectDataSource that retrieves a collection of business objects. With the collection, I am going to be binding it to a CheckBoxList and other various controls. The business object that I am using is an Employee.
To get all of the employees, I create an ObjectDataSource and set the "Select" method. I then set the DataSourceID of the CheckBoxList to be that of the ObjectDataSource. When I load the page for the first time, I see all of the employees. Now, the user goes through this page and selects all the employees they want to see information about (by checking the box next to the employee name). Finally, the user hits the button called "Display." Upon postback how do I get a list of those employees? I've tried the following solution, but I'm not sure if it's the best practice in obtaining all those employees again. Here's my solution...
In the CheckBoxList, I set the DataTextField to the Employee's name. I also set the CheckBoxList's DataValueField. This property is a little different. I set this to be a UNIQUE IDENTIFIER, which can distinguish this employee from other employees. Now, when the user hits the button "Display" I use my ObjectDataSource again and MANUALLY call ObjectDataSource.Select(). I cast the returned value as a List<Employee>. Finally, I iterate through all list items in the CheckBoxList...
[Code]....
If the item is selected, I parse through my list of employees that was returned from the bjectDataSource.Select(). I use the item.Value and compare it to each employee's "key." If the key is found, I know that the employee is selected. I put this employee in another list called EmployeesSelected.
Finally, I take EmployeesSelected (which is a List) and set my GridView's .DataSource and call .DataBind() on the GridView.
Is this the "best practice" of re-obtaining the Employees that are selected on my page, or am I making this too complicated?
i want to get the parameters in my page load event (language as C#). i dont know how the get the values for "Label", "ID", "Value" and "Mask" from the query string. all the data need to be put on the array like LabelArr, IDArr, ValueArr and MaskArr.
I have site that I need to have a vendor send an Http Post to us, using querystring parameters, then I have to look up some data and return a few results and parameters back to them. Can this be done using CLASSIC ASP? I ask this because I am still in a learning phase with .NET and have limited resources available to set up a web service.
