I have asp.net mvc site with full calendar. I also created tables like 'Event' and 'Room'. In my event table i have RoomId field.
This is how my function looks:
$(document).ready(function () {
var events = [];
var selectedEvent = null;
FetchEventAndRenderCalendar();
function FetchEventAndRenderCalendar() {
events = [];
$.ajax({
type: "GET",
url: "/CalendarEvent/GetEvents",
success: function (data) {
$.each(data, function (i, v) {
events.push({
eventID: v.Id,
title: v.Job,
description: v.Description,
start: moment(v.Start),
end: v.DutyEnd != null ? moment(v.End) : null,
room: v.RoomId,
});
})
GenerateCalender(events);
},
error: function (error) {
alert('failed');
}
})
}
On this moment, calendar displays Id. How can I refer to another table?
And this is my controller:
public JsonResult GetEvents()
{
using (Context dc = new Context())
{
dc.Configuration.LazyLoadingEnabled = false;
var events = dc.Event.ToList();
return new JsonResult { Data = events, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
}
}
You will need to join the event table with the room table. In your controller method GetEvents() you can create a select query something along the lines of the following:
var query = (from event in dc.event
join rooms in dc.rooms on event.roomId equals rooms.roomId
select new
{
eventID: event.Id,
title: event.Job,
description: event.Description,
roomId: room.RoomId,
roomName: room.Name
roomSize: room.Size
}).ToList();
Hope this helps.

I am using a multi select dropdown for a particular entry, which is retrieved from a table. If I am trying to edit this entry the selected dropdown is not showing.
This is my script.
<script type="text/javascript">
$(document).ready(function () {
//$('#Supplier').click(function () {
var sku = $("#SKU").val();
alert(sku);
//var pay = null;
//alert(suppid);
$.ajax({
url: '/SKUMasterSetup/supplierlist',
type: 'POST',
dataType: 'json',
data: { id: sku },
success: function (Supplierdata) {
alert("hi");
alert(Supplierdata);
var x = Supplierdata.length();
alert(x);
//<option value="{$T.data.Value}">{$T.data.Text}</option>
//for (var i = 0; i < Supplierdata.length; i++) {
// $("#supplier").append("Selected", Supplierdata[i], "selected").attr('selected', true);
for (var i in Supplierdata) {
var optionVal = Supplierdata[i];
$("#supplier").find("option[value=" + optionVal + "]").prop("selected", "selected");
}
// $('.class1').append("<option>" + "Please select" + "</option>");
},
//error : function (Supplier) { alert("Error !"); };
});
});
</script>
And my controller code is:
[HttpPost]
public JsonResult supplierlist(int id)
{
var Supplierdata = (from item in db.SupplierSKUMaps
where item.SKU == id
select item.SupplierMaster.SupplierName).ToList();
return Json(Supplierdata, JsonRequestBehavior.AllowGet);
}
And my dropdownlist is:
#Html.DropDownList("Supplier", ViewBag.Supplier as MultiSelectList, new { #class = "chosen", #id="supplier", #multiple = "multiple" })
you could always use #Value = #Html.Action(getMyFields) and within your controller, place an action method that returns Content result(MyData.ToList()).
More information on creating dropdowns can be found here: http://odetocode.com/blogs/scott/archive/2013/03/11/dropdownlistfor-with-asp-net-mvc.aspx
I have a problem with cascading dropdownlists where the second ddl should appear in a partial view and I can't handle it by myself. Please help me to figure out why I have the following bag?
So, I have a view with the first ddl where the user can choose a brand:
#Html.DropDownList("brands", new SelectList(
#ViewBag.Brands, "Id", "BrandName"),
"--select a Brand--",
new
{
id = "ddlBrands",
data_url = Url.Action("ChooseModel", "Home")
})
<div id="divModel"></div>
The ChooseModel method returns the following partial view :
<div id="chooseModel">
<div class="lead">Model</div>
#Html.DropDownList("models", new SelectList(Enumerable.Empty<SelectListItem>
(), "Id", "ModelName"),
"--select a Model--",
new { id = "ddlModels" })
</div>
When a user selects an item in ddlBrands another dropdownlist for models should appear. So, the script looks like this:
$(function () {
$("#ddlBrands").change(function () {
var url = $(this).data('url');
var value = $(this).val();
$('#divModel').load(url, { id: value });
var brandId = $(this).val();
$('#divModel').html("");
$.getJSON("../Home/LoadModels", { brandId: brandId },
function (modelData) {
var select = $("#ddlModels");
select.empty();
select.append($('<option/>', {
value: 0,
text: "-- select a Model --"
}));
$.each(modelData, function (index, itemData) {
select.append($('<option/>', {
value: itemData.Value,
text: itemData.Text
}));
});
});
});
});
And, finally, LooksModels method loading the models for the particular brand:
public JsonResult LoadModels(string brandId)
{
if (string.IsNullOrEmpty(brandId))
return Json(HttpNotFound());
var modelList = unitOfWork.ModelRepository
.GetModelListByBrand(Convert.ToInt32(brandId)).ToList();
var modelData = modelList.Select(m => new SelectListItem()
{
Text = m.ModelName,
Value = m.Id.ToString()
});
return Json(modelData, JsonRequestBehavior.AllowGet);
}
So, when I launch the application and choose a brand in the first ddl, the child models showing fine in second one. Then I choose another brand, and again the right models appeared. But when I choose the brand that I chose first time, I can't choose any models - ddlModels shows me only --select a Model--.
Can you please tell me what error in script (I suppose) I have?
Try this Script :
<script type="text/javascript">
$(document).ready(function () {
$("#ddlBrands").change(function () {
firstDDLValue = $("#ddlBrands").val();
$.post('#Url.Action("LoadModels", "Home")', { fstValue: firstDDLValue }, function (result) {
var select = $("#ddlModels");
select.empty();
select.append($('<option/>', { value: '', text: '--Select--' }));
$.each(result, function (index, Data) {
select.append($('<option/>', {
value: Data.Value,
text: Data.Text
}));
});
});
});
});
</script>
Use This at Controller:
public JsonResult LoadModels(string fstValue)
{
YourClassname obj= new YourClassname ();
int Id = 0;
if (fstValue != "")
Id = Convert.ToInt32(fstValue);
var result = obj.GetModelListByBrand(Convert.ToInt32(Id ));
IList<SelectListItem> Data = new List<SelectListItem>();
for (int i = 0; i < result.Count; i++)
{
Data.Add(new SelectListItem()
{
Text = result[i].Text,
Value = result[i].Value,
});
}
return Json(Data, JsonRequestBehavior.AllowGet);
}
I am working on asp.net MVC 3 applciation. I have a jquery ui dialog. On Ok button of this dialog, I am opening another jquery ui dialogue. In order to populate the newly opened popup, I am using jquery ajax call which returns a collection. I am using this collection to create table rows. Code is here:
$("#Prices").dialog({
autoOpen: false,
autoResize: true, buttons: {
"OK": function () {
var PirceCurrencies = $('#PirceCurrencies').val();
jQuery("#hdCurrencyId").val(PirceCurrencies);
jQuery(this).dialog('close');
$.ajax({
type: "POST",
dataType: "json",
url: "/Home/GetRecordingRates",
data: { Id: $("#hdCurrencyId").val() },
success: function (data) {
$("#results").find("tr:gt(0)").remove();
var messages = data.Result;
$.each(messages, function(k, v) {
var row = $('<tr>');
row.append($('<td>').html(v.DialPrefix));
row.append($('<td>').html(v.Rate));
$('#results').append(row);
});
jQuery('#RecordingRates').dialog({ closeOnEscape: false });
$(".ui-dialog-titlebar").hide();
$("#RecordingRates").dialog({ dialogClass: 'transparent' });
$('#RecordingRates').dialog('open');
}
});
}
},
open: function () {
$('.ui-dialog-buttonset').find('button:contains("OK")').focus();
$('.ui-dialog-buttonset').find('button:contains("OK")').addClass('customokbutton');
}
});
and controller action is:
public JsonResult GetRecordingRates(int Id)
{
List<DefaultRateChart> defaultRateCharts = new List<DefaultRateChart>();
Currency currency = new Currency();
using (IDefaultRateChartManager defaultRateChartManager = new ManagerFactory().GetDefaultRateChartManager())
{
defaultRateCharts = defaultRateChartManager.GetAll().Where(rc => rc.Currency.Id == Id
&& (!rc.NumberPrefix.StartsWith("#") && !rc.NumberPrefix.Equals("Subscription")
&& !rc.NumberPrefix.Equals("Default")) && rc.AccountCredit == "Credit").ToList();
}
using (ICurrencyManager currencyManager = new ManagerFactory().GetCurrencyManager())
{
currency = currencyManager.GetById(Id);
ViewBag.currecycode = currency.CurrencyCode;
ViewBag.countrycode = currency.CountryCode;
}
return this.Json( new {
Result = ( from obj
in defaultRateCharts
select new {
Id = obj.Id,
DialPrefix = obj.NumberPrefix,
Rate = obj.PurchaseRates
}
)
}, JsonRequestBehavior.AllowGet);
}
All this works fine but I need to show some other data on newly opened popup other than the collection which populates/create html table rows. Fort that do I need to make another ajax call to another controller action which will return the data ?
Please suggest
Look at what you return now in your controller:
new {
Result = ( ... )
}
You are returning an object with 1 property named Result. In your javascript code you get that object returned named data and you retrieve the Result property as your list.
What stops you from adding more properties to that list?
new {
result = ( ... ),
currencyCode = currency.CurrencyCode,
countryCode = currency.CountryCode
}
In javascript you can then use data.currencyCode and data.countryCode
From Controller Action Method you can Return Dictionary like below.
Sample Code - C#
var dic = new List<KeyValuePair<short, object>>
{
new KeyValuePair<Int16, object>(1, SomeObj),
new KeyValuePair<Int16, object>(2, SomeObj),
new KeyValuePair<short, object>(3, SomeObj),
new KeyValuePair<Int16, object>(4, SomeObj)
};
return Json(dic, JsonRequestBehavior.AllowGet);
Sample Code - JQuery- Access Dictionary objects
var obj1; //Global Variables
var obj2; //Global Variables
var obj3; //Global Variables
var obj4; //Global Variables
$.ajax({
url: url,
async: true,
type: 'GET',
data: JSON.stringify({ Parameter: Value }),
beforeSend: function (xhr, opts) {
},
contentType: 'application/json; charset=utf-8',
complete: function () { },
success: function (data) {
DataSources(data);
}
});
function DataSources(dataSet) {
obj1 = dataSet[0].Value; //Access Object 1
obj2 = dataSet[1].Value; //Access Object 2
obj3 = dataSet[2].Value; //Access Object 3
obj4 = dataSet[3].Value; //Access Object 4
}
return a Dictionary from your controller.
convert your collection to string and other object to string and return
dictionary<int, string>
in your javascript sucess function,
JSON.parse(data[0].key) will give you your collection
This will give you an idea
bool inCart = false;
Cart MyCart = default(Cart);
Dictionary<string, string> Result = new Dictionary<string, string>();
Result.Add("inCart", inCart.ToString().ToLower());
Result.Add("cartText", MyCart.CartText());
string ResultString = new JavaScriptSerializer().Serialize(Result);
return ResultString;
Here I am adding two types to a dictionary and returning my serialized dictionary
I am using jqGrid in a master detail mode. When I click on a row in the master grid I run the SelectedRowHandler javascript function which I want to update the details grid but its not working.
The selected row handler is called and the call to the action is called but the grid does not update.
Here is the js
function SelectedRowHandler(rowId) {
var rowData = this.p.data[this.p._index[rowId]];
$.ajax({
type: "POST",
url: '/Invoice/invoiceitems2',
data: { invoiceId: rowData.Id },
datatype: "json",
success: function (data) {
$("#InvoiceItemsGrid").jqGrid("GridUnload");
var mygrid = $("#InvoiceItemsGrid")[0];
var myjsongrid = eval("(" + data.responseText + ")");
myjsongrid = null;
data = null;
},
viewrecords: true
});
return true;
}
The ActionResult is
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult InvoiceItems2(int invoiceId)
{
var response = new JqGridResponse();
var invoiceItems = _invoiceItemRepository.GetMany(p => p.InvoiceId == invoiceId);
foreach (var x in invoiceItems)
{
response.Records.Add(new JqGridRecord(Convert.ToString(x.InvoiceItemId), new InvoiceItemViewModel()
{
Id = x.InvoiceItemId,
PartNo = x.PartNo,
Description =
x.Description,
Quantity = x.Quantity,
Price = x.Price,
Total =
x.Quantity*x.Price
}));
}
return new JqGridJsonResult() {Data = response};
}
I would appreciate any help.
you are not loading grid, just making an ajax call.
Why are you getting the rowdata using rowid and again using rowdata getting rowid ?
Try this instead of your ajax call
jQuery("#your_detail_grid_id").jqGrid('setGridParam',{url:"/Invoice/invoiceitems2?invoiceId="+rowId,page:1}).trigger('reloadGrid');
See the Master Detail in jqgrid demo

I have the following where I'm trying to send list/array to MVC controller method:
var id = [];
var inStock = [];
$table.find('tbody>tr').each(function() {
id.push($(this).find('.id').text());
inStock.push($(this).find('.stocked').attr('checked'));
});
var params = {};
params.ids = id;
params.stocked = inStock;
$.getJSON('MyApp/UpdateStockList', params, function() {
alert('finished');
});
in my contoller:
public JsonResult UpdateStockList(int[] ids, bool[] stocked) { }
both paramaters are null.
Note that if I change the params to single items
params.ids = 1;
params.stocked = true;
public JsonResult UpdateStockList(int ids, bool stocked) { }
then it works ok, so I don't think it's a routing issue.
Try setting the traditional flag:
$.ajax({
url: '/home/UpdateStockList',
data: { ids: [1, 2, 3], stocked: [true, false] },
traditional: true,
success: function(result) {
alert(result.status);
}
});
works fine with:
public ActionResult UpdateStockList(int[] ids, bool[] stocked)
{
return Json(new { status = "OK" }, JsonRequestBehavior.AllowGet);
}
Besides calling .ajax() instead of .getJSON() as Darin suggests or setting the global jQuery.ajaxSettings.traditional to true as jrduncans suggests, you can also pass the result of calling the jQuery .param() function on your params object:
var id = [];
var inStock = [];
$table.find('tbody>tr').each(function() {
id.push($(this).find('.id').text());
inStock.push($(this).find('.stocked').attr('checked'));
});
var params = {};
params.ids = id;
params.stocked = inStock;
$.getJSON('MyApp/UpdateStockList', $.param(params, true), function() {
alert('finished');
});
Unfortunately, while it seems that jquery provides a "traditional" flag to toggle this behavior on jQuery.ajax, it does not on jQuery.getJSON. One way to get around this would to be set the flag globally:
jQuery.ajaxSettings.traditional = true;
See the documentation for jQuery.param: http://api.jquery.com/jQuery.param/
Also see the release notes for this change: http://jquery14.com/day-01/jquery-14 (search for 'traditional')
In the view, generate multiple named fields (not id, as id should be unique per field), noting the use of Name not name:
#foreach (var item in Model.SomeDictionary)
{
#Html.TextBoxFor(modelItem => item.Value.SomeString, new { Name = "someString[]" })
}
Then retrieve the input field values using jQuery, so:
var myArrayValues = $('input[name="someString[]"]').map(function () { return $(this).val(); }).get();
You can use this directly in jQuery / AJAX as follows:
$.ajax({
type: "POST",
url: "/MyController/MyAction",
dataType: 'json',
data: {
someStrings: $('input[name="someString[]"]').map(function () { return $(this).val(); }).get(),
someDates: $('input[name="someDate[]"]').map(function () { return $(this).val(); }).get(),
Then in the controller action in MVC:
[HttpPost]
public JsonResult MyAction(string[] someStrings, DateTime[] someDates...
