I have MVC application and I have two entities.
Entity Lead inherits from Customer.
Now, In Lead controllers index view, I have written below code...
public ViewResult Index()
{
var Leads = (from c in db.Customers.OfType<CRMEntities.Lead>()
where(c.IsActive == true) select c);
return View(Leads.ToList());
}
and I have the code below in the index view.
#model IEnumerable<CRMEntities.Lead>
#{
ViewBag.Title = "Index";
}
<h2>Index</h2>
.
.
Records exist in the table it not returning any record.
Is query right?
Full View Code
#model PagedList.IPagedList<CRMEntities.Lead>
#{
ViewBag.Title = "Index";
}
<h2>Index</h2>
<p>
#Html.ActionLink("Create New", "Create")
</p>

Query looks fine from what can be seen.
The view code you are showing will not display anything. Write out #Model.Count() in the view to see how many records you have.
If you don't have a database profiler, I'd recommend getting one.

I am trying to add a checkbox so I can selects a row from my list and from there use that row to generate a letter.
I was wondering how I would be able to add a checkbox and bind it to the data I have tried a few ways using something similar to:
checkbox(m => m[i].Lesson)
However it would never accept the i in brackets and come up with an error. below is the layout of my index for the lessons model currently.
Here is the Lessons Index:
#model IEnumerable<FinalMusicApp.Models.Lesson>
#{
ViewBag.Title = "Index";
}
<h2>Lessons</h2>
<p>
#Html.ActionLink("Create New", "Create")
</p>
#using (Html.BeginForm("Index", "Students", FormMethod.Get))
{
//Search options
<b>Search Options: </b> #Html.RadioButton("Option", "Instrument")<text>Instrument</text>#Html.RadioButton("Option", "Tutor")<text>Tutor</text>#Html.RadioButton("Option", "Term")<text>Term</text>#Html.TextBox("Search")
<input type="submit" name="submit" value="Search" />
}

I am trying to add a checkbox so I can selects a row from my list
Do you want something like below?
In the view add a checkbox, for example I use the property CourseName in my model instead, you can use your property:
#Html.CheckBox("CourseName", new { value = item.CourseName })
#Html.DisplayFor(modelItem => item.CourseName)
Then in the controller, we can get CourseName value, and get other property value accord to the CourseName, but we need load the list again, we cannot send the full list from view to controller :
var courserow = model.FirstOrDefault(m => m.CourseName == CourseName);
result:
When I create a user and he's logged in for the first time I get this error when I try to display(View details) the requests that he created so far(0 request created). Once I rerun the application again with the same user the view works and I get no error. Here's the line that's generates the error:
#foreach (var item in Model)`
Here's the view that generates the error:
#model IEnumerable<Mutuelle.Domain.Entities.Demande>
#{
ViewBag.Title = "DemandesAdherent";
}
#{
Layout = "~/Views/Shared/_LayoutAdherent.cshtml";
}
<h2>DemandesAdherent</h2>
<p>
#Html.ActionLink("Creér nouvelle", "AddDemande")

#Html.DisplayNameFor(model => model.Date)

#Html.DisplayNameFor(model => model.nomBeneficiaire)

#Html.DisplayNameFor(model => model.Nomrubrique)

<th>
#Html.DisplayNameFor(model => model.etat)

#foreach (var item in Model) {

#Html.DisplayFor(modelItem => item.Date)

#Html.DisplayFor(modelItem => item.nomBeneficiaire)

I got this error when I was creating a Edit and Templating for Product.
Templates can be used only with field access, property access, single-dimension array index, or single-parameter custom indexer expressions.
Edit In my Razor View:
<p>
#Html.ActionLink("Create New", "Create")
</p>
<table>
<tr>
<th>
#Html.DisplayNameFor(model => model.Select(m => m.ProductID))
</th>
<th>
#Html.DisplayFor(model => model.Select(m => m.Name))
</th>
<th>
#Html.DisplayFor(model => model.Select(m => m.ListPrice))
</th>
<th></th>
</tr>
#foreach (var item in Model) {
<tr>
<td>
#Html.DisplayFor(modelItem => item.ProductID)
</td>
<td>
#Html.DisplayFor(modelItem => item.Name)
</td>
<td>
#Html.DisplayFor(modelItem => item.ListPrice)
</td>
<td>
#Html.ActionLink("Edit", "Edit", new { id=item.ProductID }) |
#Html.ActionLink("Details", "Details", new { id=item.ProductID }) |
#Html.ActionLink("Delete", "Delete", new { id=item.ProductID })
</td>
</tr>
}
</table>
Do you know what that mean and how to fix it? Thank you so much!
doesnt this just work?
<th> #Html.DisplayFor(model => model.ProductID) </th>
edit, try something like this:
<table id="myTable">
<tr>
<th>
#Html.DisplayNameFor(model => model.ProductID)
</th>
</tr>
#foreach (var item in Model)
{
<tr>
<td>
#Html.DisplayFor(modelItem => item.ProductID)
</td>
<td>
#Html.DisplayFor(modelItem => item.ProductID)
</td>
</tr>

Hi say I have a view containing:
<table>
<tr>
<th>
Invoice Number
</th>
<th>
Invoice Date
</th>
<th>
Organisation
</th>
<th>
Region
</th>
<th>
Total Excluding GST
</th>
<th>
Total Including GST
</th>
<th>
</th>
</tr>
#foreach (var item in Model) {
<tr>
<td>
#Html.DisplayFor(modelItem => item.InvoiceNumber)
</td>
<td>
#Html.DisplayFor(modelItem => item.InvoiceDate, "{0:D}")
</td>
<td>
#Html.DisplayFor(modelItem => item.Organisation.Name)
</td>
<td>
#Html.DisplayFor(modelItem => item.Area.Name)
</td>
<td>
#Html.DisplayFor(modelItem => item.TotalExcludingGst)
</td>
<td>
#Html.DisplayFor(modelItem => item.TotalIncludingGst)
</td>
<td>
#Html.ActionLink("Edit", "Edit", new { id = item.Id })
</td>
</tr>
}
</table>
and each item has a boolean property Editable. Is there a way to make the Edit link visible/invisible based on the value of this property?
You can use an if:
#if (item.Editable) {
#Html.ActionLink(...)
}
Basically you can use css. But if you insist in actionlink
Html.ActionLink(
"LinkName",
"Action",
null,
new { #style = "display:none" });
So if you use it with #if statement in view, you can achieve what you want.
Use CSS
I am invisible
