I am working on an MVC application and I have an index view where I pass model from controller to index view. The index action has no parameters. Now On view I have a jquery calendar. I want to change all the data on view when a date is selected. do I need to use different action method for this as current action method doesn't have parameter. or I can use same ?
View 3 RepliesI have following situation - I am pasing user info object from Controller to View. It contains GUID UserID, which i dont want to be seen on page. So I removed every Html.LabelFor(model => model.UserID), Html.TextBoxFor(model => model.UserID) etc... from generated View source. And because of this when Html.BeginForm() returns that object back to Controller all values is there but UserID is lost??
If I leave Html.LabelFor(model => model.UserID), Html.TextBoxFor(model => model.UserID) etc.. in View everything is fine. But I dont want to show UserID? Where is the problem here?
<%= Html.LabelFor(model => model.C__User_Id) %>
I have a view which takes two objects: booking and list of reasons for canceling that booking.I have two classes: clsBooking, clsBookingCancelationReason I can read both objects in my view - no problems there. After I read the objects, I display the booking details and I generate a list of cancelation reasons in the following way:
[Code]....
The code above generates a list of cancelation reasons.How do I pick up the selected ReasonId from the list?
I need to generate a link that will contain the bookingId and the selected reason for canceling the booking.I can get the bookingId out easily since it's stored in the Model...but how do I go about the selected ReasonId?
(I think) with using a data bound Custom Control on the server to get hold of my data (it will be part of a larger dataset) and to ultimately pass updates to the database. The bit I'm researching at the moment is passing that data to and from the client.One way to pass the data to the client is to use JSON within the Pageload event to construct a set of Javascript objects (one per row in the data). Is that the best way, or am I missing something?
Then, after the data has been manipulated on the client, I need to pass the rows back again so that the server side code can pick them up and process the updates. I've seen a suggestion on here that a hidden text field is one way to do that. Is it the best?Neither of my approaches seem to be at all elegant - and I suspect that I am missing something fundamental in ASP .NET AJAX!
I have a create page which is strongly typed. And when i call this through the create action method[HTTPGET] i pass some data through ViewData.
For ex
I have Event model which has Event.ID and Event.Name and my ViewData["EventData"]=Event which i pass to create page.
Now in create view which is also strongly typed to model Product where Product has Product.Name,Product.Price,Product.EventID.
for user he can only enter values for Product.Name and Product.Price and submit.
Next Create action[HTTPPOST] takes control and does the saving process.
Here is the problem the model Product which Create action[HTTPPOST] receives has Product.EventID =null, but it should be set(Event.Id) to the value which i sent to create view as ViewData[EventData]. But i dont know how to do this.
I've got a LINQ to SQL object, and I want to group the selected data and then pass it into a view. What's the correct way of doing this? I'm sure I need to group the data when I select it rather than grouping it in the view, as this will result in about 200 rather 50000 rows I need to pass into my view. Are there any good examples of this online that anyone has seen?
View 1 RepliesI have setup an httppost that sends a string into my controller, searches for some results using linq, and then sends the results to a view. In debug stepping through the code I can see the data that I am looking for being passed into the return view statement, but the page just appears to refresh (it doesn't render the view as expected with the result). why my controller fails to redender the view? (note: I didn't include the view because I can send a ToList() to it without an issue. For example, return View(_entities.Persons.ToList());
[HttpPost]
public ActionResult RenderSearch(string usersearchtext)
{
if (usersearchtext != null)
{
var search_results = from s in _entities.Persons
where s.Description.Contains(usersearchtext)
select s;
return View("SearchResult", search_results.ToList());
}
else
{
throw new NotImplementedException();
}
}
I have a dictionary I'm passing to a View. I want to be able to pass the values of that dictionary back to a Controller action from this same View. Is there anyway this can be accomplished without using a form? The situation is that I need to be able to pass these back to a controller action that is called when a user clicks an ActionLink from the View, and in my experience an ActionLink cannot be used to submit a values of a form, i.e. I've only been able to submit values of a form using the form's submit button. Unless there's a way to use an ActionLink to submit values in a form.Controller Action passes Dictionary to Controller in ViewData:
public ActionResult ModifyNewCrossListing(FormCollection form)
{
Dictionary<int, string> prefixlist = new Dictionary<int, String>();

I'm trying to build a Create view in which some fields for the model have been set in the controller and are non-editable. Take for example a post in these forums where the subforum in which you post depends on which forum you're in currently.
I tried to do this by passing an id parameter to the Create action like this:
[Code]....
[Code]....
But somehow the subforum property gets "lost" along the way, but the submitted prop. stays there. I should note here that the subforum property is an entity key.
So in other words: how can I set a few properties before returning the view, and keep these read-only until postback??

How Can we Show Data in a View By passing a jsonResult?
View 1 RepliesIs there a way to easily passed around an ID between controller actions on the same controller?I.E. I have an Index action which takes an ID parameter, and when a user creates a new post I would like them to go back to the index page with the same ID.Currently I am just passing it around in my view model, but it seems real cumbersome and I was wondering if there was a better way to do this?

I have the following to get the Json abject passed from the controller and populate the various textboxes in the view. However, nothing is happening even though controller is passing a valid Json object. What is wrong with this code?
<script language="javascript" type="text/javascript">
$(document).ready(function() {
var url = '<%=Url.Action("DropDownChange") %>';
$("#vendorID").change(function() {
var selectedID = $(this).val();
if (selectedID != "New Vendor Id") {
//$.post('Url.Action("DropDownChange","Refunds")', function(result) {
$.post(url, { dropdownValue: selectedID }, function(result) {
alert(selectedID);
$("#name").val(result.Name);
$("#city").val(result.City);
$("#contact").val(result.Contact);
$("#address2").val(result.Address2);
$("#address1").val(result.Address1);
$("#state").val(result.State);
$("#zip").val(result.Zip);
});
}
});
});
This is the code in my controller;
public JsonResult DropDownChange(string dropdownValue)
// This action method gets called via an ajax request
{
if (dropdownValue != null && Request.IsAjaxRequest() == true)
{
paymentApplicationRefund =
cPaymentRepository.PayableEntity(dropdownValue);
paymentApplicationRefund.Address1.Trim();
paymentApplicationRefund.Address2.Trim();
paymentApplicationRefund.Name.Trim();

return Json(paymentApplicationRefund,"application/json");

I'm using a grid view to display a number of records from a database.
Each row has an Edit Button. When the button is clicked I want an ID to be passed back to a funtion in my .cs file. How do I bind the rowID to the Button field?
I've tired using a hyper link instead but this doens't seem to work because I'm posting back to the same page which already has a Permanter on the URL.
<asp:GridView ID="gvAddresses" runat="server" onrowcommand="Edit_Row">

I have a partial view that has only a dropdown, i have called this partial view from a view. I can able to pass the model to this partial view and it renders successfully. However when some user selects a particular text from the dropdown, the corresponding value should be passed to view and it should be displayed in the label in view.
View 7 RepliesI have 3 drop downs in a details view (populated from a gridview) during insert mode.
Dropdown 1
Dropdown 2 --> Based on drop down one
Dropdown 3 --> Based on drop down two
I am curious of how to handle the autopostback to update 2 and 3 since they are part of the detailsview, there isn't a selected_index_changed event.
I am ok with adding items to them on page load, just not for cascading of them...
'm using a textbox to get the first 5 letters of the name.
An sqldatasource then finds the people who have names > than the five letters and picks up their ID numbers as well as their names.
After that I use a second sqldatasource to get one individual from that dropdownlist's persons name and id number and then using a detailsview I display that person.
Well both sqldatasouces work fine but it just does not pass the ID number when I debug it.
