I have one actionlink inside the foreach loop. Depending on the model items I am generating link buttons with values dynamically.
This is how it looks
#foreach (var group in Model.records)
{
<tr>
<td>#Html.ActionLink(#group.clientId.ToString(), "detailsbyClientId", "DocumentVerification", new { id = #group.clientId.ToString()},null)</td>
<td>#group.clientName</td>
<td>#group.Count</td>
</tr>
}
On clicking link button i am calling partial view as below.
[HttpGet]
public PartialViewResult detailsbyClientId(int? clientId)
{
return PartialView();
}
I am receiving a null value for clientId but #group.clientId.ToString() contains a valid value.
The parameter in your method is named clientId but your generating a query string value named id. Change one or the other to match
public PartialViewResult detailsbyClientId(int? ID)
{
....
}
and in the view
#Html.ActionLink(#group.clientId.ToString(), "detailsbyClientId", "DocumentVerification", new { id = group.clientId },null)
Note you do not need the # nor .ToString() in the 4th parameter - just new { id = group.clientId }
Try this:
The point is the name of the variable you are passing and the name of the variable that is expecting the value in the controller should be the same.
#foreach (var group in Model.records)
{
<tr>
<td>#Html.ActionLink(#group.clientId.ToString(), "detailsbyClientId", "DocumentVerification", new { clientId = group.clientId},null)</td>
<td>#group.clientName</td>
<td>#group.Count</td>
</tr>
}
[HttpGet]
public PartialViewResult detailsbyClientId(int? clientId)
{
return PartialView();
}

My Model is
public class IssueEntryModel
{
public IEnumerable<SelectListItem> OrderNumbers { get; set; }
public string SelectedWorkOrder { get; set; }
public string MaterialCode
{
get; set;
}
public List<GroupedIssueData> MaterialData { get; set; }
}
And the view is
#model InventoryEasy15.Models.IssueEntryModel
#{
var issueData = Model.MaterialData;
var workorders = Model.SelectedWorkOrder;
}
#using (Html.BeginForm("SaveIssueEntry", "IssueMaster", FormMethod.Post, new { id = "issueEntryForm" }))
{
#for (int i = 0; i < issueData.Count(); i++)
{
<tr>
<td>#issueData[i].MaterialCode</td>
<td>#issueData[i].MaterialDescription</td>
<td>#issueData[i].Unit</td>
<td>#issueData[i].ReqQty</td>
<td>#Html.TextBoxFor(m => issueData[i].IssueQty, new { style = "width:70px" })#Html.ValidationMessageFor(m => issueData[i].IssueQty)</td>
<td class="text-center">#Html.CheckBoxFor(m => issueData[i].isSavings)</td>
</tr>
}
And I have post method as
public ActionResult SaveIssueEntry(IssueEntryModel model)
{
var result = new Dictionary<string, string>();
And the get contains the details to fill the view as
//Method Get the material details based on the work order id
public async Task<ActionResult> GetWorkOrderMaterialDetails(IssueEntryModel m)
{
During post to a new method , the model is becomes null, Any thoughts?
Razor uses the expression passed to the HTML helpers in order to build the proper name for the inputs that will allow the modelbinder to bind them properly on post. That means the expression needs to match the access method of the property exactly. By saving Model.MaterialData to the issueData variable and utilizing that, you're disrupting this. In other words, you're ending up with inputs named like issueData[0].IssueQty, instead of MaterialData[0].IssueQty. The modelbinder doesn't know what to do with issueData on post, because nothing on your model matches that.
Long and short, your textbox needs to be declared like:
#Html.TextBoxFor(m => m.MaterialData[i].IssueQty, ...)
Similarly for your checkbox:
#Html.CheckBoxFor(m => m.MaterialData[i].isSavings)
I have a textbox in my mvc view.I want to pass the textbox data in beginform route values.how to do that?
View:
#using (Html.BeginForm("Index", "InwardDetail", FormMethod.Post))
{
<fieldset style="width:80%;margin-left:auto;margin-right:auto;margin-top:20px;min-width:60%">
<div>
<table class="tableView" style="width:100%">
<tr>
<td>
#Html.DevExpress().Label(lbl=>{
lbl.Name = "lblFromDate";
lbl.Text = "From Date";
}).GetHtml()
</td>
<td>
#Html.TextBox("txtFromDate", value: DateTime.Now.ToString("dd/MM/yyyy"), htmlAttributes: new {id="fromDate", Class="textbox",style="width:70px"})
</td>
<td>
#Html.DevExpress().Button(but=>{
but.Name = "butView";
but.Text = "View";
but.UseSubmitBehavior = true;
}).GetHtml()
</td>
</tr>
<tr>
<td colspan="9">
#Html.Partial("InwardDetailPartial")
</td>
</tr>
</table>
</div>
</fieldset>
}
Controller:
public ActionResult Index(string fDate)
{
_unitOfWork = new UnitOfWork();
blInwarddetail = new InwardRegisterBL(_unitOfWork);
var result = blInwarddetail.GetInwardList(fDate);
return View("Index", result);
}
If I click Button the values should be passed to controller.
Your use of #Html.TextBox("txtFromDate", ..) means you generate an input with name="textFromDate". When you submit a form, the name/value pairs of the forms controls are sent - in your case it would be txtFromDate: 27/06/2015.
But the method your posting to does not have a parameter named txtFromDate (only one named fDate). You need to change the method to
[HttpPost]
public ActionResult Index(string txtFromDate)
{
....
}
However there are numerous issues with your code that you should address
First you should create a view model to represent what your wanting to display/edit in a view
public class FilterViewModel
{
[Display(Name = "...")] // some user friendly display name
[Required(ErrorMesage = "Please enter a valid date")]
public DateTime Date { get; set; }
}
Note from the code you have shown it appears your entering a date, not a string so the property should be DateTime (not string). This also ensures that you get client and server validation for the property. I also give your properties a more descriptive name that fDate (I can't begin to guess what that might mean - maybe FinishDate?)
In the GET method
public ActionResult Index()
{
FilterViewModel model = new FilterViewModel();
model.Date = DateTime.Today;
return View(model);
}
And in the view
#model yourAssembly.FilterViewModel
#using (Html.BeginForm())
{
....
#Html.LabelFor(m => m.Date)
#Html.TextBoxFor(m => m.Date, "{0:dd/MM/yyyy}", new { #class = "textbox" })
#Html.ValidationMessageFor(m => m.Date)
....
}
Note that you are now strongly binding to your model property. The second parameter specifies the format string. There seems no need to override the id property (which will be id="Date"), and to add a class name use #class = "..". Note also since you are adding a class name, you should remove style="width:70px" and instead use css. You should also remove the table elements. Html table elements are used for tabular data, not for layout.
And finally the post method will be
[HttpPost]
public ActionResult Index(FilterViewModel model)
{
if (!ModelState.IsValid)
{
return View(model);
}
// model.Date will contain the value enter by the user
}
Finally I would question if this really should be a POST. Form the code, you don't appear to be changing any data and perhaps this should be FormMethod.GET? Or better, use ajax to update the current page based on the filter.
I was trying to get my CompanyProfile ID in my UserController
in the first step i get the right ID but in the [HttpPost] the ID value was change into the same value as the user ID
This is my controller
public ActionResult Edit (int id)
{
User user = _db.Users.Find(id);
if ( user == null)
{
return HttpNotFound();
}
ViewBag.CompanyProfile = new SelectList(_db.CompanyProfiles,"ID","NamaProfil", user.CompanyProfile.ID);
return View(user);
}
[HttpPost]
public ActionResult Edit(User user)
{
if (ModelState.IsValid)
{
_db.Entry(user).State = EntityState.Modified;
_db.SaveChanges();
return RedirectToAction ("Index");
}
return View(user);
}
this is the Model
public int ID {get;set;}
public virtual CompanyProfile CompanyProfile {get;set;}
and this is the dropdown in the edit view
<div class= "controls">
#Html.DropDownList("CompanyProfile", null, "--Choose Company--", new {#class="span6 m-wrap"})
</div>
every answer may help,thanks :D
forget to tell this,this is the error message
There is no ViewData item of type 'IEnumerable' that has the key 'CompanyProfile'.
You have a number of issues here. The model you are passing in to your view has a property named CompanyProfile of reference type CompanyProfile. This type cannot be bound to IEnumerable of any kind - those two models simply don't match. Your model property needs to be of type int to match with the selected value you are passing in - user.CompanyProfile.ID.
2nd issue is that you should never name your model property the same as any ViewBag value. Again you have a property named CompanyProfile and you have a ViewBag.CompanyProfile. Those two will be overwriting each other during the model binding...
I suggest you do the following: In your controller bind the select list to a ViewBag without defining the selected value:
ViewBag.CompanyProfileList = new SelectList(_db.CompanyProfiles,"ID","NamaProfil");
Then your model should have the selected company profile id property:
public int CompanyProfileId { get; set; }
And then bind it in your view like this:
#Html.DropDownListFor(m => m.CompanyProfileId, (SelectList)ViewBag.CompanyProfileList, "--Choose Company--", new { #class = "span6 m-wrap" })
I am working on an MVC4 application. In the submit action of the button, i am making a call to a controller action, which will return data back to me as Json. Number of rows in the table is dependent on the number of rows returned by the service.
I have created a new View Model to support this.
public class DataResponse
{
public List<ALSResult> Result { get; set; }
public string ResponseText {get;set;}
}
public class ALSResult
{
public string Name {get;set;}
public string DataResult {get;set;}
}
Controller Action
[HttpPost]
public ActionResult Submit(CViewModel calcModel)
{
try
{
DataResponse response = cRepository.GetDetails(calcModel.SelectedPlan,calcModel.EquipmentPrice,calcModel.DownPayment);
return Json(response, JsonRequestBehavior.DenyGet);
}
}
js file
$("#Submit").click(function () {
other code here
Process("/DPPC/Submit", "POST", JSON.stringify(model), "json", "application/json;charset=utf-8", logError, InvokeSuccess);
}
function InvokeSuccess(result) {
i will get json result in result filed
}
index.cshtml
<table id="tblResults">
<tr>
<td id="tdResultEt"></td>
<td id="tdResultEtPrice"></td>
</tr>
<tr>
<td id="tdResultDt"></td>
<td id="tdResultDtPrice"></td>
</tr>
more rows depending on the number of items in the JSON response
</table>
How do i dynamically bind the response from the Service to create rows for the table and bind the results?
I don't test it, and it maybe contain syntax errors
function InvokeSuccess(result) {
var table = $("#tblResults");
for(var i = 0; i < result.Result.lenght; ++i)
{
var item = result.Result[i];
var newTr = $("<tr>");
var newTd1 = $("<td>");
var newTd2 = $("<td>");
newTd1.text(item.Name);
newTd2.text(item.DataResult);
newTr.append(newTd1);
newTr.append(newTd2);
table.append(newTr);
}
}
I have run into an issue that seems pretty simple, but I have not been able to find a solution. I have created a ReportModel object that is the model in the view. The ReportModel contains a list of FinancialHistory objects. I populate the objects and display them in a table of textboxes within a form in the view using default binding (This works correctly). The user can then submit the form to refresh the FinancialHistory objects from a different datasource, replacing what was previously in the list with the new results. When the new results are returned, I can see that the model contains the expected new values, but when the HTML is rendered, the original amounts still appear. If the new results contains more objects than the original list (as shown in the example code), the added rows do appear with the correct values. So, if the original had 2 objects and the refreshed list has 3, the resulting HTML shows the first 2 rows with the old values and a 3rd row with the new values.
Here are the models:
public class ReportModel
{
public string AccountNumber { get; set; }
public IList<FinancialHistory> FinancialHistories { get; set; }
}
public class FinancialHistory
{
public FinancialHistory()
{
Id = Guid.Empty;
}
public Guid Id { get; set; }
public DateTime TransactionDate { get; set; }
public decimal TotalAmount { get; set; }
}
In the Home/Index view, I use HTML.TextBoxFor() to bind the properties of each FianancialHistory object in the list to textboxes in a table. Here is the Index view:
#model SimpleExample.Models.ReportModel
<form id="FormSave" method="post" name="FormSave" action="/Home/Refresh">
#Html.LabelFor(model => model.AccountNumber) #Html.TextBoxFor(model => model.AccountNumber)
<table class="table" style="width: 95%">
<tr>
<td >Date</td>
<td >Amount</td>
</tr>
#{
if (Model.FinancialHistories != null)
{
for (int index = 0; index <= Model.FinancialHistories.Count - 1; index++)
{
<tr>
<td>#Html.TextBoxFor(model => model.FinancialHistories [index].TransactionDate, "{0:MM/dd/yyyy}", new { #readonly = "true" })</td>
<td>#Html.TextBoxFor(model => model.FinancialHistories[index].TotalAmount, "{0:#,#.00}", new { #readonly = "true" })</td>
<td>#Html.HiddenFor(model => model.FinancialHistories[index].Id)</td>
</tr>
}
}
}
</table>
<input type="submit" id="submit" value="Refresh" class="submit" />
</form>
For this example, my action methods in the controller are very simple. Initially, the Index method populates the list with 2 FinancialHistory Objects. The Refresh method replaces the original 2 objects with 3 new objects, with different amounts.
public class HomeController : Controller
{
public ActionResult Index()
{
ReportModel reportModel = new ReportModel();
reportModel.AccountNumber = "123456789";
IList<FinancialHistory> financialHistories = new List<FinancialHistory>();
financialHistories.Add(new FinancialHistory
{
Id = Guid.NewGuid(),
TransactionDate = DateTime.Parse("3/1/2010"),
TotalAmount = 1000.00M
});
financialHistories.Add(new FinancialHistory
{
Id = Guid.NewGuid(),
TransactionDate = DateTime.Parse("4/1/2011"),
TotalAmount = 2000.00M
});
reportModel.FinancialHistories = financialHistories;
return View(reportModel);
}
public ActionResult Refresh(ReportModel reportModel)
{
FinancialHistoryRepository financialHistoryRepository = new FinancialHistoryRepository();
IList<FinancialHistory> financialHistories = new List<FinancialHistory>();
financialHistories.Add(new FinancialHistory
{
Id = Guid.Empty,
TransactionDate = DateTime.Parse("3/1/2010"),
TotalAmount = 1111.11M
});
financialHistories.Add(new FinancialHistory
{
Id = Guid.Empty,
TransactionDate = DateTime.Parse("4/1/2011"),
TotalAmount = 2222.22M
});
financialHistories.Add(new FinancialHistory
{
Id = Guid.Empty,
TransactionDate = DateTime.Parse("5/1/2012"),
TotalAmount = 3333.33M
});
reportModel.FinancialHistories = financialHistories;
return View("Index",reportModel);
}
}
That's how HTML helpers work and is by design. When rendering they are first looking in the ModelState for values and after that in the model. You are modifying the values of your model in the POST controller action, but the ModelState values still contain the old values which will be used. If you want to modify values of your model in a POST action you should remove the original values from the ModelState if you intend to redisplay the same view:
public ActionResult Refresh(ReportModel reportModel)
{
// clear the original posted values so that they don't get picked up
// by the helpers
ModelState.Clear();
FinancialHistoryRepository financialHistoryRepository = new FinancialHistoryRepository();
...
return View("Index",reportModel);
}
