I've been using Html.Action("ActionName", "ControllerName") to invoke child actions across controllers without needing to have the view in ViewsShared. This has been working great for displaying things like session or cookie information.
Instead of just accessing cookies, I would like to pass additional parameters to Html.Action("ActionName", "ControllerName") so the action can execute different code based on the the data passed to the original view.
Should I be using a different method to pass parameters to a child action in a different controller?
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 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.
I have a page with list box and user can select multiple values from that lst box. Now what I want to do is when user submits the page I want to generate a comma seprated string that contins the ID's of values selected and pass this string to stored procedure. String would look like something like that '2,5,9'
Now my question is how can I split these ids in my stored procedure and get the records based on these ID's. In want to pass this array to Source coloumn in the follwoing Stored procedure and get the data. Right now following stored procedure is working on the basis of single source id passed to it.
[Code]....
I have the following structure:
private struct S_indiv
{
public int[] x;
public int s;
public S_indiv(int[] p1, int p2)
{
x = p1;
s = p2;
}
}
and array:
private static S_indiv[] ind;
How can I pass this array through Postback?
I am trying to implement the autocomplete method for textboxes.
I would like to use the example based on jquerys autocomplete provided here
<head>
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script>
$(document).ready(function() {
$("input#autocomplete").autocomplete({
source: ["c++", "java", "php", "coldfusion", "javascript", "asp", "ruby"]
});
});
</script>
</head>
The first and Main problem is that i do not know the way of passing my values to the source:
By saying that i mean, supposing i have a a server-side ASP.NET function GetTheResults as listof(string) or GetTheResults as string ()
how am i supposed to pass those values as source required by the auto-complete?
The second problem is that the specific way does not use AJAX.
Which means i guess on the load of the form i will load all the available values to the source. Isn't that an overkill?
I am trying to get this functionality on my jokes website:
www.mysite.com/category/bar
To get all the bar jokes ..etc
The way I have my route right now is:
{controller}/{action}/{id}
which means I have to type:
www.mysite.com/category/index/bar
the problem is that even with that, the string parameter "bar" isn't being acknowledged ! ( I know from debugging). Here is my Index action in the Category controller:

I have some textboxes and a table of data created client side that I want pass to a controller as JSON.
I want to use Jquery to enumerate the table.
Assume I have 2 textboxes called name and age. Assume a table with 2 columns. one column with class called phonetype and one column class called phonenumber.
So how do construct the JSON from this?
I have created a VS 2008 web setup project with a dialog so that I can modify the web.config file at install. The setup worked as expected. However, I can not seem to accept a URL for a property value via custom data. I know directories are escaped with "", is there any similar escaping or tricks for a URL.

My Controller:

PS. Id love to pass the entire model from the View -> Controller - but it complains about not having a parameterless constructor (which i do)
I have the following action executed when a user selects an item from the dropdown;

My problem with the following is how do I send the ModelStateErrors to the action Employee, when I go through the catch part in DeleteEmployee

With return View("Employee", model); I a still not able to send the ID and Name as parameter.
I am having one controller Test having following actions
(1)public ActionResult ABC (string parameter1, string parameter2)
(2)public ActionResult XYZ (string parameter1, string parameter2,string parameter3, string parameter4)
i have added following html.routelinks
<%= Html.RouteLink("ABC","ABC", new { parameter1 = 100, parameter2 = 200 } )%><br />
<%= Html.RouteLink("XYZ", "XYZ", new { parameter1 = 1000 , parameter2 = 2000 }) %>
last two parameters in XYZ action are optionals so i have not passed them in Html.routelink
routes.MapRoute("ABC", "Test/{parameter1}/{parameter2}", new { controller = "Test", action = "ABC", parameter1= 0,parameter2=0 });
routes.MapRoute("XYZ", "Test/{parameter1}/{parameter2}/{parameter3}/{parameter4}", new { controller = "Test", action = "XYZ", parameter1=0,parameter2=0 ,parameter3=UrlParameter.Optional,parameter4=UrlParameter.Optional});
In above senario in both cases same route "ABC" is called eventhough i have clicked on second Html.routelink. can anyone solve this issue ? how can i route according to route name instead of number of parameters?
I'm trying to implement paging in my app, so i need to know what page the user wants to click on, as well as pass the model (for some fields)I'm able to pass the desired page, just not the model (for the search criteria)here is my view:

[Code]....
My ViewModel SearchResults has a string property "Search". When i do it this way searchModel == null in the NextPage Action.
Is there a control that you can use? It can be done by fetching a binaryread from an aspx page but why there isn't a simple free image control that you can put in the page and feed it a byte array?
View 15 RepliesI am passing an array from .aspx page to different .cs page. It's not working for me
View 12 RepliesI have an array which contains around 50-200 hyperlinks. How can I pass this array to the client-side so that I can iterate through the array and display each hyperlinks as a list item?
The array will be stored in 'Application' as it's system wide and rarely changes. Could there be a more efficient way of achieving the hyperlinks as a list?
What I have is a table that holds 3 input elements, They represent order, name, value. The user can add a new row of 3 inputs to add as many of these sets of data as they want.
To accomplish the dynamically adding in of inputs I use jquery's clone method. That works fine and I am able to iterate through each and grab the values, however the real pain I am having is that when the user has entered in all of the data I want to pass that data to an asp.net page through jQuery's post method. How do I go about passing an array of strings so that I send this format to the asp.net page, and when I've done that how do i parse the data on the asp.net side of it.
Desired Data Format:
["Name|Link|Order", "Name|Link|Order", "Name|Link|Order"]
jquery Code so far:
$("#saveBtn").click(function (e) {
e.preventDefault();
$("#addPanel").slideUp(300);
//Perform Save Operation
var saveString = "";
$("#addTable tbody>tr").each(function () {
var o = $(this).find(".hsaorder").val();
var n = $(this).find(".hsaname").val();
var l = $(this).find(".hsalink").val();
saveString += n + "|" + l + "|" + o ;
});
////// Create Array here or some other method?
$.post("/modules/H/Modify.aspx", { OBVIOUSLY SOMETHING GOES HERE});
// Remove all but top table element to return to original state
$("#addTable tbody>tr").not("#addTable tbody>tr:first").remove();
});
How can I pass the content of a File to a array of bytes?
View 3 RepliesIs there any possibility to pass values of form elements to action methods but using parameters?I have a form with a lot of input fields and the method signature will get pretty long. Besides the form elements depend on each other so if the user makes a special choice only a subset of the form elements should be displayed so there are several combinationof values to be passed.Can I access the posted values in a generic way through a collection in the controller or something similar?
View 3 RepliesMy query is somehow related to passing the id values as parameters in MapRoute on RegisteredRoute method
routes.MapRoute("MachineGroupList:, PhysicalMachine/ListGroupMachine/{used}/Page/{page}", new {controller="PhysicalMachine", action="ListGroupMachine",id="XNA"});
How can i use {used} value in id ?
My Page have:
<%: Html.RouteLink("<<<", "MachineGroupList", new{used=Model.UsedBy,page=(Model.PageIndex-1),id=Model.UsedBy})%>
My controller for this Action is:
public ActionResult ListGroupMachine(string id, int page=0)
{
....
}
Everytime I call this Action the Id should be of groupBy column; over here it is 'Used' First time I have called this Action from <%html.ActionLink("Machine","ListGroupMachine", new {id=Model.UsedBy})%> But in my Html.RouteLink the id object is not identified in MapRoute method...
