mvc getting and sending data from dropdown and datetimepicker - asp.net-mvc

Question

hello everyone I have a question. I have a form which consist of dropdown textbox and datetimepicker. I can fill my dropdown from my model but I cannot post the data to the database. Here are my codes
My Controller codes this is where the data selected and shown in view
public ActionResult orderProduct()
{
Repository<OrderProduct> _ro = new Repository<OrderProduct>();
IEnumerable<OrderProduct> _orderProduct = _ro.All().OrderByDescending(o => o.id);
return View(_orderProduct);
}
I am filling the dropdownlist from database
public ActionResult addOrderProduct()
{
/*
Repository<Workshop> _rw = new Repository<Workshop>();
IEnumerable<Workshop> _workshop = _rw.All().OrderByDescending(o => o.id);
IEnumerable<SelectListItem> _selectList = from w in _workshop
select new SelectListItem {
Text = w.name,
Value = w.id.ToString()
};
*/
Repository<Workshop> _rw = new Repository<Workshop>();
IEnumerable<SelectListItem> _workshopSelectListItem = _rw.All().AsEnumerable().Select(s =>
new SelectListItem {
Text = s.name, Value=s.id.ToString()
});
ViewData["dropdown"] = _workshopSelectListItem;
return View();
}
here I am trying to post my data to the database. I cannot select data from dropdown and datetimepicker also I cannot post this data by writing manually.
public ActionResult orderProductAdd(int adet, float cmt)
{
Repository<OrderProduct> _rp = new Repository<OrderProduct>();
OrderProduct _orderProduct = new OrderProduct { workshopId = 1, orderId = 1, value = adet, shipDate = new DateTime(2005, 02, 01), cmt = cmt };
return RedirectToAction("orderProduct");
}
this is my model
[Table("OrderProduct")]
public class OrderProduct
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int id { get; set; }
public int orderId { get; set; }
[ForeignKey("orderId")]
public virtual Order order { get; set; }
public int workshopId { get; set; }
[ForeignKey("workshopId")]
public virtual Workshop workshop { get; set; }
public int value { get; set; }
public float cmt { get; set; }
public DateTime shipDate { get; set; }
/*
[id]
,[orderId]
,[workshopId]
,[value]
,[cmt]
,[shipDate]
*/
}
and also this is my view "addOrderProduct"
<form action="/Order/orderProductAdd" class="form-horizontal">
<div class="control-group">
<label class="control-label">Atölye Seçiniz</label>
<div class="controls">
#Html.DropDownList("dropdown",(IEnumerable<SelectListItem>)ViewData["dropdown"],"secim yapınız", new { #class = "span6 chosen" })
#*<select class="span6 chosen" data-placeholder="Choose a Category" tabindex="1">
<option value=""></option>
<option value="Category 1">A1</option>
<option value="Category 2">A2</option>
<option value="Category 3">A3</option>
<option value="Category 4">A4</option>
</select>*#
</div>
</div>
<div class="control-group">
<label class="control-label">Adet Giriniz</label>
<div class="controls">
<input type="text" class="span6 " name="adet" />
<span class="help-inline">Sadece sayı giriniz</span>
</div>
</div>
<div class="control-group last">
<label class="control-label">İhracat Tarihi</label>
<div class="controls">
<div id="ui_date_picker_inline"></div>
</div>
</div>
<div class="control-group">
<label class="control-label">Cmt</label>
<div class="controls">
<input type="text" class="span6 " name="cmt" />
</div>
</div>
<div class="form-actions">
<button type="submit" class="btn btn-success">Onayla</button>
#*<button type="button" class="btn">Cancel</button>*#
</div>
</form>
How can I solve this ? Thank you.

Answer 1

The first argument in the DDL (below) is the assigned parameter being passed back to the server. When you call the action you're not passing the parameter dropdown. You're only calling int adet, float cmt but not a parameter called dropdown
#Html.DropDownList("dropdown",(IEnumerable<SelectListItem>)ViewData["dropdown"],
"secim yapınız", new { #class = "span6 chosen" })
So update your code to something like the one below:
public ActionResult orderProductAdd(int adet, float cmt, string dropdown){
// DO SOMETHING HERE
}
I can't see the input control which is being constructed for the DATETIME part of your query, however it will be similar to the above. Ensure the name of the INPUT matches the parameters being passed back to the server.
