I am trying to create a dynamic table that is being built based on the value of a search text box. The Table will have probably 6 columns of 20(max) rows.
My problem is I can't figure out how to return the data from the web-service to the JS function in a way that will allow me to extract the data that I need.
Here is the web-service method I have currently:
[code]....
I need to write a webservice that returns multiple rows from a table. I am familiar with return of a single object.
I am calling a stored procedure in the webservice that populates a data table.
I guess I need to define an object collection to be returned. Should this be an array or can I return the data table itself?
I know i've seen a tutorial for this, but can't locate it anymore. I have a class Employee in c# side, I also have a webservice where I pass in an ID# and an Employee object is returned. Now I want this object returned to Javascript code, I know I've seen it done before, can someone point me to a tutorial that shows something like this being done. I'm using the MicrosoftAjax.js file.
View 3 RepliesI'm calling a web service called GetTooltip from inside Javascript. However, since the web service is called asynchronously, it doesn't wait until I get the return value from the web service, before it continues again. This is a bit of a problem for me, since the web service is in a for-loop. How do I make the Javascript wait until I hear back from the web service, before letting Javascript continue the for-loop?

I created a very simple webService using the VS2008 template. i am planning to use Ajax call for the webService.when i try to open my webservice in IE browser using following link to see the Javascript proxy, it return blank page.[URL]
View 3 RepliesI am struggling to create a webservice method using LINQ technology and to populate a dropdown in a form. Here is the Webservice code.
[WebMethod]
public
string[] GetAllCountries()
{
LinqClassesDataContext db =
new
LinqClassesDataContext();
var q =
from c
in db.ListContinents()select
c;
return q.ToList() ;
}
And here is the form code behind
protectedvoid
Page_Load(object sender,
EventArgs e)
{
WSClass WS =
new
WSClass();//bool
ds = WS.GetAllCountries();
var v = WS.GetAllCountries();
ddlContinent.DataSource = v;
ddlContinent.DataBind();
}
I've created a static table, which looks just as I would expect it to, but I want to reduce my work in the future, as I'll need to create more rows and columns to store extra data that's added to my application.
So rather than creating new rows and columns whenever I need to, I'd like to automate the task by pulling the data from the database and populating a table that's dynamically created based on how much data is pulled.
e.g. if there are 10 rows of items in the database, create 10 columns and 10 rows, if a further 5 things get added next week, I want to add another 5 rows and 5 columns etc
Is this where "Dynamic Data" would play a role? If so, it's completely new to me, my needs are just for a single table on a page, not something that needs to be done en'masse all over the website, if that makes a difference?
Iam getting an array of list from database to client side(javascript array). Now my aim to place those values in a div one by one and that div should attach to the textbox similar to Autocomplete extender.
View 4 RepliesI am trying to consume an array of strings from a webservice that I wrote. I keep getting the error: "System.NullReferenceException: Object reference not set to an instance of an object."
I know I am doing some thing wrong at an extremely basic level, but it's not coming to me.
I have tried adding New but get the error that you can't declare arrays with New
Here is the dummed down webservice method:<WebMethod( _
Description:="Testing ")> _
Public Function TestArray(ByVal Address1 As String, ByVal zip As String) As String()
Dim strTest(4) As String
strTest(0) = "It's"
strTest(1) = "a"
strTest(2) = "great"
strTest(3) = "day"
Return strTest
End Function
<--Here is the call that generates the null reference error-->
Private Sub FindAddress()
Dim svc As ws.Service
Dim strAddresses() As String
strAddresses = svc.TestArray(txtAddress.Text, txtZip.Text)
End Sub
I want to know how we can create a table (or a layout consisting of div's) and poulate it with data from the database. We do this generally using data controls like gridview, datalist etc. But i am restricted by these controls like there is no inbuilt paging with datalist and there is no repeat column in gridview. I just want complete control over the layout as well as the data that goes into it.
I dont know how to do this. Is there anyway of doing it without using the data controls.
The website I am working on will contain a drop-down list that shows a number of reason codes.
Is it possible to populate a drop-down list with an array derived from a custom class?
Something like this:
ASPX Page
<asp:DropDownList ID="ddlReasonsWhy" runat="server"></asp:DropDownList>
ASPX Code Behind
protected void Page_Load(object sender, EventArgs e)
{
//instantiate custom class
Class1 reasonsList = new Class1();
//populate reasons list

I have a array of ArrayList as shown below:ArrayList[] m;My web service method takes this type as parameter.How can I send it to web service?When I do so the Web Service changes my array of ArrayList to Object[][]!

Now I wanna know how can I send Arraylist Array to webservice, because when I want to call this function it wants object[][] data type.
how to pass a C# ASP.NET array to a Javascript array? Sample code will also be nice.
Let's say for simplicity that in my aspx.cs file I declare:
int [] numbers = new int[5];
now I want to pass "numbers" to the client side and use the data in the array within javascript. How would I do this?
I have information in a database wich need to be shared with a java (Flex) application that uses the SpringGraph component to show a network layout.
Since that component creates the graphic structure based on XML, I believe Web Services are the best solution.
The problem is, here's an example of the component's XML:
[Code]....
The sample above means that "e1" is connected to "e2" and "e2" is connected to "e3".
I know how to create a web method that return a "single" class. Like "int IsValidUser" or even "User UserData", but how can I return that structure?
In the web servce I say
public List<Customer> GetCustomers()
{
PR1Entities dc = new PR1Entities();
var q = (from x in dc.Customers
select x).ToList();
return q;
}
(customer is a entity object)
Then I generate the proxy when I add the service.. and in the reference.cd it say
public wcf1.ServiceReference1.Customer[] GetCustomers() {
return base.Channel.GetCustomers();
}
WHY IS IT AN ARRAY? I asked for a List.
I need to create a table with just 1 column containing times (starting from 4hrs) which increase in increments of 10 seconds for each row. So it needs to look something like this:
04hrs 00mins 00secs - 04hrs 00mins 09secs
04hrs 00mins 10secs - 04hrs 00mins 19secs
04hrs 00mins 20secs - 04hrs 00mins 29secs
.....
06hrs 59mins 50secs - 06hrs 59mins 59secs
This will obviously take a long long time to hard code so I'm looking to create it dynamically. Based on what i'm currently trying to learn I'd like to be able to do this using jquery or asp.net (vb) but anything will do as long as it works!

What's wrong?
Edit: And what if I need to return {Message:'',Type:1} ?
Edit2: The answer for the last one is: I can return a Dictionary<string, string>

View 7 RepliesI have to set GridView.DataKeyNames(This is really a question about the syntax for a string array, in VB.Net.)
I am discovering the PrimaryKey columns names from within a loop, ie:
For Each fld As IEntityField In Me.llbDataSource.EntityCollection(0).PrimaryKeyFields 'fld.Name ' this is where the column name is stored, so I have to get this into an array Next I can not use this syntax.
GridView.DataKeyNames = new string() { "PowRatHP", "Voltage", "Phases", "Poles", "Drive" }
So, basically, how does one declare a string array (as required by GridView.DataKeyNames), and then populate the elements of the array from within a loop?

I am trying to return some data as json from an action method.
I have an employee object that looks like this:
public class Employee
{
public int EmployeeID {get; set;}
public string FirstName {get; set;}
public string LastName {get; set;}
//Other irrelevant properties
}
Then I have a view model as follows
public Class EmployeeViewModel
{
public Employee Supervisor{get; set;}
public List<EmployeeViewModel> Employees
}
I need to return a json object that looks exactly like this:
{id: 1, name: John, children: [
{id: 1, name: Joe, children: []},
{id: 1, name: Rob, children: []}
]}
For now I only need to go to the second level as above, returning and supervisor and their staff members beneath them.
How would I go about returning this in my action method(I have the viewModel object hydrated already I just need to return it as json). My problem so far has been that the children property does not get populated.
