How to change MVC Web Grid structure? - asp.net-mvc-4

I am trying to show list of items in a MVC 4 Web Grid control. But I am unable to re-format my web grid as table structure below.
Web Grid structure like this.
Table structure like this.
Here is my razor code for web grid.
#{
var grid = new WebGrid(Model.EnrollPlanPriceLevelList, canPage: true, rowsPerPage: 10, selectionFieldName: "id", ajaxUpdateContainerId: "gridContent");
grid.Pager(WebGridPagerModes.NextPrevious);
if (grid.HasSelection)
{
var EnrollPlanPriceLevelID = grid.Rows[grid.SelectedIndex].Value;
}
}
#grid.GetHtml(
tableStyle: "table table-condensed table-striped table-hover no-margin",
headerStyle: "",
mode: WebGridPagerModes.All,
columns:
grid.Columns(
grid.Column("", format: (item) => item.GetSelectLink(item.EnrollPlanPriceLevelID.ToString())),
grid.Column("SchoolYears.Name", "School Year"),
grid.Column("EnrollPlans.PlanName", "Enroll Plan"),
grid.Column("PriceLevels.Name", "Price Level"),
grid.Column("Price", "Price"),
grid.Column("", format: #<text>#Html.Label("Edit", new { #id = item.EnrollPlanPriceLevelID, #class = "badge", #onclick = "bindplanprogram(" + item.EnrollPlanPriceLevelID + ")" }) </text>),
grid.Column("", format: #<text>#Html.ActionLink("Delete", "Delete", new { id = item.EnrollPlanPriceLevelID }, new { #class = "badge" }) </text>)
))
Here is the table structure
<table class="table table-condensed table-striped table-hover no-margin">
<thead>
<tr>
<th>School Year
</th>
<th>Enroll Plan</th>
<th>
<span class="span3">Early Bird</span>
<span class="span3">Value Pricing</span>
<span class="span4">Standard Pricing</span>

I want to reformate my web grid structure as above table structure. Please tell me someone! How to change web grid structure accordingly?

The only way to achieve what you want with the WebGrid is to change the shape of the data you are passing in. Whether you do that in your SQL or whether you do that using LINQ to create a collection of anonymous types that have the appropriate properties is up to you, but the end result must be a collection of items that have public properties that match what you want as column names.

<tr>
<td>

</td>
<td>

</td>
<td class="text-right">
<input id="#item.Items.ItemID + 'UnitPrice'" class="form-control text-right" value="#item.Items.ItemUnitPrice" />
</td>
<td class="text-right">

</td>

I can't get the value of HTML element using javascript is there anyway or proper way of setting an id of each quantity input? Or any keywords to search regarding this one.
According to your code and description, I assume you want to calculate the cost based on the Quantity and the ItemUnitPrice. If that is the case, please refer to the following sample code, you can refer it to change your code:
ViewModel:
public class ItemViewModel
{
public int ItemId { get; set; }
public string ItemDescription { get; set; }
public decimal ItemUnitPrice { get; set; }
public decimalc Quantity { get; set; }
}
Index.cshtml: we could set the id attribute like this id='Quantity_#item.ItemId', after rendering, the output like Quantity_XXX:
#model IEnumerable<WebApplication6.Models.ItemViewModel>
<table class="table">
<thead>
<tr>
...
</tr>
</thead>
<tbody>
#foreach (var item in Model)
{
<tr>
<td>
#item.ItemId
</td>
<td>
#item.ItemDescription
</td>
<td class="text-right">
<input id="ItemUnitPrice_#item.ItemId" class="form-control text-right" type="text" value="#item.ItemUnitPrice" />
</td>
<td class="text-right">
<input id='Quantity_#item.ItemId' class="form-control text-right txtquantity" type="text" value="#item.Quantity" oninput="return change_quantity(this,#item.ItemId)" />
</td>
<td class="text-right">
#(item.Quantity * item.ItemUnitPrice)
</td>
<td>
<a class="btn btn-sm btn-danger btn-rounded" asp-controller="purchaseorderheader" asp-action="Remove" asp-route-id="#item.ItemId"><span class="fa fa-trash"></span></a>
</td>
</tr>
}
</tbody>
</table>
Then at the end of the Index.cshtml page, add the following JavaScript: we could use the parent() and closest() method to find the current row, and then find the relates elements in this row.
#section Scripts{
<script>
function change_quantity(e, itemid) {
//find the item unit price.
var price = $("#" + "ItemUnitPrice_" + itemid).val();
//find the quantity value.
var quantity = $("#" + "Quantity_" + itemid).val();
//calculate the cost and change the html content.
$(e).parent().closest("tr").find(".text-right:last").html((price * quantity).toFixed(2).toString());
}
</script>
}
The output like this:
you can use this approach
#foreach (var item in Model)
{
<tr id="tr-#item.ItemId">
<td>
#item.ItemId
</td>
<td>
#item.ItemDescription
</td>
<td class="text-right">
<input id="ItemUnitPrice_#item.ItemId" class="form-control text-right" type="text" value="#item.ItemUnitPrice" />
</td>
<td class="text-right">
<input id='Quantity_#item.ItemId' class="form-control text-right txtquantity" type="text" value="#item.Quantity" oninput="return change_quantity(this,#item.ItemId)" />
</td>
<td class="text-right">
#(item.Quantity * item.ItemUnitPrice)
</td>
<td>
<a class="btn btn-sm btn-danger btn-rounded" asp-controller="purchaseorderheader" asp-action="Remove" asp-route-id="#item.ItemId"><span class="fa fa-trash"></span></a>
</td>
</tr>
}

How to click on inneHTML String with Selenium?

I am iterating throw a table getting the rows:
<div class="table-responsive">
<table class="table table-striped" id="noteTable">
<thead>
<tr>
<th style="width: 20%" scope="col"></th>
<th style="width: 20%" scope="col">Title</th>
<th style="width: 60%" scope="col">Description</th>
</tr>
</thead>
<tbody>
<tr id="notes" th:each="note : ${notes}">
<td>
<a class="btn btn-success" id="btn-edit-note"
th:onclick="showNoteModal([[${note.id}]],
[[${note.noteTitle}]], [[${note.noteDescription}]])">Edit</a>
<a th:href="#{|/home/delete-note/?title=${note.noteTitle}|}"
id="btn-delete-note" class="btn btn-danger">Delete</a>
</td>
<th scope="row" th:text="${note.noteTitle}"></th>
<td th:text="${note.noteDescription}"></td>
</tr>
</tbody>
</table>
</div>
With this code written below :
public void deleteNote(String title, String description) {
WebDriverWait wait = new WebDriverWait(driver, 2);
WebElement btnDeleteNote;
js.executeScript("arguments[0].click();", tabNotes);
WebElement homeWait = wait.until(webDriver ->
webDriver.findElement(By.id("btn-delete-note")));
for (WebElement note : notes) {
String noteTitle = note.getAttribute("innerHTML");
System.out.println(noteTitle);
if (noteTitle.contains(title)) {
js.executeScript("DELETE NOTE HERE);
}
}
}
When I get the row innerHTML I receive this result as String :
<td>
<a class="btn btn-success" id="btn-edit-note" onclick="showNoteModal(1,
"Note Title Test", "Note Description Test")">Edit</a>
Delete
</td>
<th scope="row">Note Title Test</th>
<td>Note Description Test</td>
- My question is: Thinking that the lines of a Table are Dynamic, how can I click on "< a >" tag element in the string row?
The element has to be unique because it has an id so you can just target it like this:
element = driver.find_element_by_id("btn-delete-note")
print(element.text)

Viewbag can be unreliable so generally it isn't recommended to pass your drop down list data through the viewbag. I would recommend adding it to your view model instead. In your Event_Setup class make sure that you have
public int EventTypeID { get; set; }
and
public List<SelectListItem> EventTypeList { get; set; }
on your controller get you can set EventTypeID to set a default on the drop down so your controller should have something like
Event_Setup es = new Event_Setup();
es.EventTypeID = //default value if you want;
es.EventTypeList = //Method call here where List<SelectListItem> is returned with your event list
then on your view you can change your drop down to
#Html.DropDownListFor(x => x.EventTypeID, Model.EventTypeList)

Accordion within table rows

I am using Twitter Bootstrap. Currently I am working on Master Details looks alike table, which I am planning to place an accordion into each table's row and if it is expanded, the partial view will be reload and displayed.
Somehow it does not work as expected but if I change it to Modal, the partial view loaded perfectly.
This is the controller that process and returning the values:
public ActionResult Index(int id,int? page)
{
List<CustomerProduct> customerProducts =
(from c in RepositoryProduct.Reload(id)
select c).ToList<CustomerProduct>();
return PartialView("_CustomerProducts", customerProducts);
}
and this is the table in the view :
<table id="tbl" class="table table-condensed" style="border-collapse:collapse;">
<thead>
<tr>
<th>
#Html.ActionLink("Customer Name", "Index", new { sortOrder = ViewBag.NameSortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
#Html.DisplayNameFor(model => model.First().CustLocalName)
</th>
<th>
#Html.ActionLink("Country", "Index", new { sortOrder = ViewBag.CountrySortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
#Html.DisplayNameFor(model => model.First().City)
</th>
</tr>
</thead>
<tbody>
#foreach (var item in Model)
{
<tr data-toggle="collapse">
<td style="display:none;">
#Html.DisplayFor(modelItem => item.CustID)
</td>
<td>
#Html.DisplayFor(modelItem => item.CustName)
</td>
<td>
#Html.DisplayFor(modelItem => item.CustLocalName)
</td>
<td>
#Html.DisplayFor(modelItem => item.Country.CountryName)
</td>
<td>
#Html.DisplayFor(modelItem => item.City)
</td>
<td>
<a class="btn btn-small btn-info" type="button" href="#Url.Action("Index", "CustomerProduct", new { id = item.CustID })" data-toggle="collapse" data-target="##item.CustID" >Products</a>
</td>
</tr>
<tr>
<td colspan="6" class="hiddenRow">
<div id="#item.CustID" class="accordian-body collapse" tabindex="-1">
<div class="accordion-header">
<label>
<strong>#item.CustName product(s)</strong>
</label>
</div>
<div class="accordion-body">TEST</div>
</div>
</td>
</tr>
}
</tbody>
</table>
this is part of the code that calling the controller Index function :
<a class="btn btn-small btn-info" type="button" href="#Url.Action("Index", "CustomerProduct", new { id = item.CustID })" data-toggle="collapse" data-target="##item.CustID" >Products</a>
Actually I would like to load the partialview(_CustomerProduct) in the div class="accordion-body" as what I did in div class="modal-body" but no success. May I know if it is possible to do it and if yes, may I know how?
Any help will be appreciated.
for me to get the view to work i used
<td colspan="6" class="hiddenRow">
<div id="#item.CustID" class="accordian-body collapse" tabindex="-1">
<div class="accordion-header">
<label>
<strong>#item.CustName product(s)</strong>
</label>
</div>
<div class="accordion-body">
#Html.Partial("_CustomerProduct")
</div>
</div>
</td>

Saving the value of a Selectlist item when used in a for each loop in a view

Part of my MVC 3 VB.NET has a view that uses a list(of model) and a for each on that model to list all the contents.. The problem is that a selectlist is part of each item.. When the value is selected for each item it is not being posted back to the controller with the rest of the items... The view code is as follows:
#ModelTYPE List(Of xxxxxxx.attendance)
#Code
ViewData("Title") = "Class Attendance Record"
End Code
#Using Html.BeginForm
#<fieldset>
<table>
<tr>
<th>
First Name
</th>
<th>
Last Name
</th>
<th>
Registrant ID
</th>
<th>
Course Status
</th>
<th>
Comments
</th>
</tr>
#For r As Integer = 0 To Model.Count - 1
Dim i As Integer = r
#Html.HiddenFor(Function(m) m(i).id)
#<tr>
<td>
#Html.DisplayFor(Function(m) m(i).firstName)
#Html.HiddenFor(Function(m) m(i).firstName)
</td>.
<td>
#Html.DisplayFor(Function(m) m(i).lastName)
#Html.HiddenFor(Function(m) m(i).lastName)
</td>
<td>
#Html.DisplayFor(Function(m) m(i).reg_id)
#Html.HiddenFor(Function(m) m(i).reg_id)
</td>
<td>
#Html.DisplayFor(Function(m) m(i).Completed_Class)
</td>
<td>
#Html.DropDownList("Completed_Class", New SelectList(ViewBag.courseStatus, "Status", "Status"), New With {.Completed_Class = "Completed_Class"})
#Html.HiddenFor(Function(m) m(i).Completed_Class)
</td>
<td>
#Html.TextBoxFor(Function(m) m(i).Comments, New With {.class = "AttenComment"})
#Html.HiddenFor(Function(m) m(i).Comments)
</td>
</tr>
Next
</table>
<p>
<input type="submit" name="submit" />
</p>
</fieldset>
End Using
Any ideas how I can assign the selectedvalue to the HiddenFor??
Instead of writing loops, I would recommend you using editor templates. Like this:
#ModelTYPE List(Of xxxxxxx.attendance)
#Code
ViewData("Title") = "Class Attendance Record"
End Code
#Using Html.BeginForm
#<fieldset>
<table>
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>Registrant ID</th>
<th>Course Status</th>
<th>Comments</th>
</tr>
#Html.EditorForModel()
</table>
<p><input type="submit" name="submit" /></p>
</fieldset>
End Using
and inside the corresponding editor template (~/Views/Shared/EditorTemplates/attendance.vbhtml or ~/Views/SomeController/EditorTemplates/attendance.vbhtml) which will be rendered for each element of the collection:
#ModelTYPE xxxxxxx.attendance
#Html.HiddenFor(Function(m) m.id)
#<tr>
<td>
#Html.DisplayFor(Function(m) m.firstName)
#Html.HiddenFor(Function(m) m.firstName)
</td>
<td>
#Html.DisplayFor(Function(m) m.lastName)
#Html.HiddenFor(Function(m) m.lastName)
</td>
<td>
#Html.DisplayFor(Function(m) m.reg_id)
#Html.HiddenFor(Function(m) m.reg_id)
</td>
<td>
#Html.DisplayFor(Function(m) m.Completed_Class)
</td>
<td>
#Html.DropDownList("Completed_Class", New SelectList(ViewBag.courseStatus, "Status", "Status"), New With {.Completed_Class = "Completed_Class"})
#Html.HiddenFor(Function(m) m.Completed_Class)
</td>
<td>
#Html.TextBoxFor(Function(m) m.Comments, New With {.class = "AttenComment"})
#Html.HiddenFor(Function(m) m.Comments)
</td>
</tr>
This being said, using all those hidden fields reminds me badly for the classic WebForms ViewState. You don't need it. Believe me, you really don't need this stuff. Use input fields if you allow the user to modify something (text fields, radios, checkboxes, etc...), but hidden fields, come on! A single hidden field containing the id of the model will largely suffice for the controller action to fetch the corresponding model from the datastore that it initially fetched it from.
As far as your dropdown is concerned:
#Html.DropDownList("Completed_Class", New SelectList(ViewBag.courseStatus, "Status", "Status"), New With {.Completed_Class = "Completed_Class"})
You should use a property on your view model to bind to and use the strongly typed version:
#Html.DropDownListFor(Function(m) m.CompletedCLass, New SelectList(ViewBag.courseStatus, "Status", "Status"), New With {.Completed_Class = "Completed_Class"})
