I want to pass a int value using RedirectToAction() method .
Here i have a Action method Index() which takes 1 parameter id in most of the cases this id cannot be null.
When i submit the form using Action method Edit(), i want to come again on Index page,so i am using method RedirectToAction("Index")
but here with Action Name i want to pass the id also. How can i do it?
My method looks like:
public static RedirectToResult(Controller controller, ...)
{
}
when I do:
controller.
I don't see RedirectToAction, how come?
I get RedirectToAction from within the controller's action, but not when I pass the controller as a parameter to another classes method.
I have the following ActionResult() method:
[Code]....
The method is called once the <form> is submitted. If the validation is good, it moves on to create a new user Once the new user is created, I want to redirect the user to a "ThankYou" page passing along the newly created user (object). The TempData["User"] trick seems to work like a charm! Then inside my ThankYou ActionResult() I do the following:
[Code]....
The problem I have is once the user has been redirected to the "ThankYou" page. If he decides to refresh (F5) his browser, the value in the TempData is lost.
What are my possibilities to overcome this issue?
Instead of passing an entire object to my "ThankYou" page, I initially thought of passing the ID of the newly created user and re-query my database to get the object.
The only problem is that the ID will be seen in the QueryString allowing the user to simply change the ID value and try to find other users...
Is my only other alternative to simply place the user object inside a Session? Is that my only other option?
I am using VS 2008 SP1. My also have included CSS Friendly adapter [URL] in my project ( I mentioned this because my GridView Empty data template is not showing when using GridView's CCS Friendly adapter). I have a GridView and a DetailsView. When a record in GridView is selected its details information is shown in the Details View. Type of Data source I am using is ObjectDataSource. My Insert and Update methods works perfectly. It is only the Delete method that is passing null values to the underlying object delete method. My source codes for both the UI, BLL, DAL is shown below
[Code]....
My Business Object code is below :

My Data Access Layer Code is:

I am probably totally missing the point here but....
How can I pass a 'var' into another method?
(I am using linq to load XML into an Enumerable list of objects).
I have differernt object types (with different fields), but the final step of my process is the same regardless of which object is being used.
XNamespace xmlns = ScehmaName;
var result = from e in XElement.Load(XMLDocumentLocation).Elements(xmlns + ElementName)
select new Object1
{
Field1 = (string)e.Element(xmlns + "field1"),
Field2 = (string)e.Element(xmlns + "field2")
};
var result2 = Enumerable.Distinct(result);
This code will vary for the different type of XML files that will be processed. But I then want to iterate though the code to check for various issues:
foreach (var w in result2)
{
if (w.CheckIT())
{
//do something
}
}
What I would love is the final step to be in a method in the base class, and I can pass the 'var' varible into it from each child class.
public ActionResult RenderMyThing(IList<String> strings)
{
return View("RenderMyView");
}
How do I pass in strings?
routes.MapRoute("MyRoute", "RenderMyThing.aspx", new { controller = "My", action = "RenderMyThing" });
Is there a way I could pass in strings here?
Secondly, how does ASP.NET MVC know that action is my action, and controller is my controller. Like I saw this in samples, and it does work, but isn't it just an anonymous object with no type?
I'm sure something like this worked before for taking a type and pass it to another action method (I cannot / never use TempData)
[Code
i want to pass multidementional array as parameter, below the code i worked, is it right
class ASRateContract
{
public string[,] standardrate = new string[3,2];
public string[,] storagerate = new string[3,3];
public void setstandardrate( string [3,2]name )
{
standardrate = name;
}
public string setstoragerate()
{
return "";
}
public string getstandardrate()
{
return standardrate;
}
I am using ASP.NET MVC 3 and the YUI library.I created my own helper method to redirect to an edit view by passing in the item's ID from the Model as such:
window.location = '@Url.RouteUrl(Url.NewsEdit(@Model.NewsId))';
Now I am busy populating my YUI data table and would like to call my helper method like above, not sure if it is possible because I get the item's ID by JavaScript like:
var formatActionLinks = function (oCell, oRecord, oColumn, oData) {
var newsId = oRecord.getData('NewsId');
oCell.innerHTML = '<a href="/News/Edit/' + newsId + '">Edit</a>';
};
In one view (view1) there is a text box and a button beside it. i click on that button, i am popping another view (Create view) as a seperate window. in create view i am entering some values and creating a record in db. out of these values one value i have to send back to "View1". how can i send this value? i am opening view2 from view1 like
<input type="button" value="Get ID"
onclick="window.open('<%=Url.Action("Create","Controller1") %>',
'','scrollbars=yes,width=800,height=800,resizable=yes');"
/>
View2 contains some fields like Name,Email etc... and I click "Create" to call HTTPPOST. there i add the values to db including a generated guid. i want to send this ID to view1.
I am creating a Web Service, which will be used by a client to send data to our Database.The client will be sending close to 30 fields that will be updated to our table. If I write a Web method, I will need to have all these 30 fields as parameters to that method. Is there a better way than sending all of them as parameters?
View 3 Repliesi have the following method, however i want to pass methods to it, i know how to do it the usual way, however when it comes to Webservices/API's what is the correct way to do it. Here is my method so far;
[Code]....
I have this function:
[System.Web.Services.WebMethod]
public static string EditPage(string nodeID)[code]....
in my Web Form but When I try to reference their IDs they don't auto complete and can't be found.
I have a actionresult index method in my controller and a http post method for the same name. when i run the program the control should go to the http post method but by default it goes to the index method.
[code]...
I have a web service called service1. Is it possible to pass the parameter related to the service to a class library so for e.g.
Service1.service ws = new Service1.service();
Service1.UserDetails ud = null;
now if I call a method that exists in a class and pass ud. Cam i do that because I am trying to do this and I am getting an error. Do i need to add a web
reference to this service in the class library My method call is like this
authenticateUser.Authenticate(ud, UserName);
and in the class libary I have
public void Authenticate( Service1.UserDetails ud , string UserName)
{
}
I am using a template file for the ItemTemplate of the repeater control.
Within the template I am trying to get the value from the current datarow.
The code was then converted from VB to C# and I am getting the following error:
'System.Web.UI.Control' does not contain a definition for 'DataItem'
Below are the C# and VB versions:
[Code]....
Converted C#:
In .ascx...
<%#GetAssociationName((RepeaterItem)Container.DataItem)%>
In .ascx.cs...
Then get the value using the following method.
[Code]....
I'm attempting to use a Button's OnCommand method to handle it's click event so that the event is passed on to OnPreRender method as shown below. So basically the OnPreRender method is called upon a button click. I'm need to use the OnCommand method because I have 2 buttons.
//mark up
<asp:DataPager ID="GroupSearchResultPager" runat="server" OnPreRender="groupSearch_PreRender" >
<asp:Button ID="btnSearchUser" runat="server" Text="Search" OnClick="btnSearchUser_Click" CommandName="searchUser" />
//code behind
protected void btnSearchGroup_Click(object sender, CommandEventArgs e)
{
groupSearch_PreRender(this, e); //call groupSearch_PreRender
}
protected void groupSearchView_PreRender(object sender, CommandEventArgs e)
{
if(e.CommandName=="searchUser")
{
do stuff
}
}
However, this results in the following exception:
CS0123: No overload for 'groupSearch_PreRender' matches delegate 'System.EventHandler' So basically groupSearch_PreRender only takes an EventArg. I've tried casting as shown below but it doesn't seem to work. How else can I pass the button click event to the PreRender method?
protected void groupSearchView_PreRender(object sender, EventArgs e)
{
CommandEventArg entry = (CommandEventArg)e; //casting to CommandEventArg
if(entry.CommandName=="searchUser")
{
do stuff
}
}
input type=..... value="<%= ISO3166CountryList.GetCountryByCode("IE", CurrentLocale).Name %>" />
I'm looking to replace the hardcoded IE with something like
<%#(Container.DataItem as PhoneNumber).ISO%>
No variations of what I've tried worked. How can I get a databinded value when within a <%= code block? Do I need to use an intermediary variable?
I'm fairly new to MVC and admittedly don't fully understand how data is passed between Views and Controllers. That said, here is my issue.
I am working with C#. I have a page which has a list of items. Each item has a radio button set of three associated with it and there are 15 of these sets on the page. Thus I have radio1, radio2....radio15, etc. Each of these has value 0, 1, or 2 upon submit. I can't seem to understand how to get the information out of these radio button sets from the controller without passing 15 different variables to the post method in the controller which is associated with the view; ie passing Int32 radio1, Int32
radio2,.., Int32 radio15, etc.
I tried using ViewData["radio"+i] in a loop to access the value of each radio button set, but this, apparently can only be used to pass data to the View from the Controller and not the other way around.
I want to pass create date in Membership CreateUser(..., ..., ...) method. As It's only providing no such method of passing custom create date of an user(s). Is there a way to pass it? I'm using .NET Framework 2.0. If there is no such way then have any idea my Microsoft is not providing this functionality for passing custom value(s) as store procedure is implemented all the table parameter(s).
View 1 Repliesi want to make some questions about asp.net MVC,actually,i am not familiar with web developing.
But,i am assigned for web part.we are using like this.first,we create get set
properties for person data
public class Person
{
public int personID {get;set;}
public string personName {get;set;}
public string nric {get;set;}
}
and then after login,we put data in that class and we use RedirectToAction method like this,
return RedirectToAction("profile","person",new { personID = Person.personID});
it's working normally,but,parameter are shown at URL,how i hide them and also can i hide action name?
I have created a custom validation attribute for a class. The validation is actually against one property of the class, but since it needs to be compared to another property of the class at runtime, I had to pull in everything from the input form, perform the validation and output the errors. This being the case, I manually added a ModelError to ModelState if the ModelStats.IsValid returned false. I have another thread that goes into this, as I still haven't been able to make the client-side validation work for the custom validation (built-in validation runs client-side without a problem).
Here's the issue: I want to use the Post/Redirect/Get pattern to avoid issues where users refresh their page and cause another post of the form data. If I complete my Controller action and return a View after assigning an error with ModelState.AddModelError, I get the user feedback with the red input field and error message shown. However, just returning a View like this makes you vulnerable to the repeated posts issue. I want to use RedirectToAction to perform a get and avoid this problem, but when I do that I no longer have the ModelState error feedback on my rendered View. Here're the calls I'm making:
[Code]....
I'd like to be able to redirect to a get action and retain the ModelState.
I wish to do something like this:
return RedirectToAction<SomeController>(c => Index(someparameter));
How to do this ?
I use the RedirectToAction with parameters in my action method
return RedirectToAction("ListThreads", "View", new { category = "1", subcategory = "49"});
After redirect the url comes out like this
http://domain/Forum/View/ListThreads?category=1&subcategory=49
I want it to be generated like
http://domain/Forum/View/ListThreads/1/49
How to do it?
Note : I already have a route in global.asax that is used by all the pages/links.
context.MapRoute(
"Forum_subcategory",
"Forum/{controller}/{action}/{category}/{subcategory}",
new { controller = "View", action = "ListThreads", category = "", subcategory = "" }
);
I've a class that hold all the necessary properties. I want to pass the instance of that class in RedirectToAction. Right now, I can pass the instance but the action to which it redirect, doesn't receive that same instance. The target action has new instance of class.
eg.
AbcFilter a = new AbcFilter();
a.ABCname="abc";
RedirectToAction("AbcAction",a);
Public ActionResult AbcAction(AbcFilter a)
{// this method receives the "a" as new instance, but not the same that I pass in RedirectToAction
}
