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?

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 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 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>();

View 4 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'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??

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.Contact.Trim();

paymentApplicationRefund.Zip.Trim();
return Json(paymentApplicationRefund,"application/json");
}

return null;

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">

'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.
Got some records in a sql table. What i would like to do is display all the records on a webpage and group them by state, so that the display would look something like:
California
Entry 1
Entry 2
Entry 3
New York
Entry 1
Entry 2
Entry 3
Other (for entries with no state)
Entry 1
Entry 2
What would be the best method to do this? And I'm open to using anything up to and including .net 4.0/vs2010
