This is a demo of CRUD(Create,Update,Delete) MVC 5 app + Entity Framework + Reactjs
I'm trying to convert the tags below into reactjs components and render whole page but the problem is the razor lines. When rendering it just shows the text.
What should I do?
Customer View Index:
<h2>Index</h2>
<div id="root">
</div>
<p>
#Html.ActionLink("Add New Customer", "Create")
</p>
<table class="table">
<tr>
<th>
#Html.DisplayNameFor(model => model.Name)
</th>
<th>
#Html.DisplayNameFor(model => model.Address)
</th>
<th></th>
</tr>
#foreach (var item in Model)
{
<tr>
<td>
#Html.DisplayFor(modelItem => item.Name)
</td>
<td>
#Html.DisplayFor(modelItem => item.Address)
</td>
<td>
#Html.ActionLink("Edit", "Edit", new { id = item.Id }) |
#Html.ActionLink("Details", "Details", new { id = item.Id }) |
#Html.ActionLink("Delete", "Delete", new { id = item.Id })
</td>
</tr>
}
Reacjs.jsx
class Table extends React.Component {
render() {
return (
<div className="Table">
#Html.ActionLink("Add New Customer", "Create")
</div>
);
}
}
ReactDOM.render(
<Table />, document.getElementById('root')
);
I have written code to implement search using ajax in asp.net MVC. I have written an action inside my controller (Admincontroller) using partial view which is supposed to fetch data. I want to display the partial view result inside table body in my Index page.
The search function is working fine, but it is not displaying the result inside table body with id "searchresult" (Inside Index page). instead of that it is giving result. I wanted the result from search in table format. now result is displayed like below in http://localhost:1274/Admin/Search.

How to handle errors in Razor (i.e. Null Exception)other than (try/catch)?
I do not want to insert (try/catch) block in every razor block.
Example (The (Model.ListofEntity) or (Item.Values) may be null and an exception might occur):
<table class="table">
<tr>
<th>
<div id="chkCheckAll" class="divCheckbox">
</div>
</th>
#foreach (var column in Model.ListofEntity.Columns)
{
int t = Convert.ToInt32(" ");
<th>
#column
</th>
}
</tr>
#foreach (CVMEntities.Item Item in Model.ListofEntity.Items)
{
<tr>
<td>
<div id=#Item.ID class="divCheckbox">
</div>
</td>
#foreach (var Value in Item.Values)
{
<td>
#Value
</td>
}
</tr>
}
</table>
I'm creating a project for my institute. Using Asp.net MVC, I need multiple delete option with selected checkbox.
I have added a check in my view, but not delete multiple Raw. I don't want to use third party plugin. Please help me.
<table class="table table-striped table-condensed table-bordered">
<tr>
<th>
Select
</th>
<th>
#Html.ActionLink("Book Id", "Index", new { sortOrder = ViewBag.IdSortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
#Html.ActionLink("Title", "Index", new { sortOrder = ViewBag.NameSortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
#Html.ActionLink("Date", "Index", new { sortOrder = ViewBag.DateSortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
Price
</th>
<th>
Category
</th>
<th class="text-center">
Photo
</th>
<th>
User
</th>
<th>Edit</th>
<th>Delete</th>
</tr>
#foreach (var item in Model)
{
<tr>
<td>
<input type="checkbox" name="deleteInputs" value="#item.BookId" />
</td>
<td>
#Html.DisplayFor(modelItem => item.BookId)
</td>
<td>
#Html.ActionLink(item.BookTitle, "Details", new
{
id = item.BookId
})
</td>
<td>
#Html.DisplayFor(modelItem => item.PublishDate)
</td>
<td>
#Html.DisplayFor(modelItem => item.Price)
</td>
<td>
#Html.DisplayFor(modelItem => item.Category)
</td>
<td class="text-center">
<img class="img-thumbnail" width="50" height="50" src="~/ContentImages/Full/#item.Photo" />
</td>
<td>
#Html.DisplayFor(modelItem => item.UserName)
</td>
<td>
#Html.ActionLink("Edit", "Edit", new { id = item.BookId })
</td>
<td>
#Html.ActionLink("Delete", "Delete", new { id = item.BookId })
</td>
</tr>
}
</table>
This could be a way to achieve it:
First embed the table within a named form, that executes the batch delete action, like so:
#{ Html.BeginForm("BatchDelete", "Book", FormMethod.Post, new { name = "tableForm" }); }
<table class="table table-striped table-condensed table-bordered">
<tr>
<th>
Select
</th>
<th>
#Html.ActionLink("Book Id", "Index", new { sortOrder = ViewBag.IdSortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
#Html.ActionLink("Title", "Index", new { sortOrder = ViewBag.NameSortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
#Html.ActionLink("Date", "Index", new { sortOrder = ViewBag.DateSortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
Price
</th>
<th>
Category
</th>
<th class="text-center">
Photo
</th>
<th>
User
</th>
<th>Edit</th>
<th>Delete</th>
</tr>
#foreach (var item in Model)
{
<tr>
<td>
<input type="checkbox" name="deleteInputs" value="#item.BookId" />
</td>
<td>
#Html.DisplayFor(modelItem => item.BookId)
</td>
<td>
#Html.ActionLink(item.BookTitle, "Details", new
{
id = item.BookId
})
</td>
<td>
#Html.DisplayFor(modelItem => item.PublishDate)
</td>
<td>
#Html.DisplayFor(modelItem => item.Price)
</td>
<td>
#Html.DisplayFor(modelItem => item.Category)
</td>
<td class="text-center">
<img class="img-thumbnail" width="50" height="50" src="~/ContentImages/Full/#item.Photo" />
</td>
<td>
#Html.DisplayFor(modelItem => item.UserName)
</td>
<td>
#Html.ActionLink("Edit", "Edit", new { id = item.BookId })
</td>
<td>
#Html.ActionLink("Delete", "Delete", new { id = item.BookId })
</td>
</tr>
}
</table>
<!-- Section for buttons -->
<div class="actions">
<a href="javascript:(function(){document.tableForm.submit();return void(0);})()">
Delete selected books
</a>
</div>
#{ Html.EndForm(); }
Note that after the table, before ending the form, I added a link that executes the submit of the form.
Now, on the controller side, asumming its name is "BookController":
public class BookController : Controller
{
// ...
[HttpPost]
public ActionResult BatchDelete(int[] deleteInputs)
{
// You have your books IDs on the deleteInputs array
if (deleteInputs != null && deleteInputs.Length > 0)
{
// If there is any book to delete
// Perform your delete in the database or datasource HERE
}
// And finally, redirect to the action that lists the books
// (let's assume it's Index)
return RedirectToAction("Index");
}
// ...
}
Notice that:
The first two parameter of the Html.BeginForm method, are the action name and controller name (without the "Controller" suffix).
The last parameter of the same method include the name of the form. The name is used in the javascript of the link, in order to indicate which form are you going to submit.
First, you need a different Id for each checkbox so you know which record is to be deleted. Second, if you implement "delete" as a link then the browser will perform a GET action instead of a POST. Assuming you are not using AJAX then you will need a form so you can POST to the controller action which handles the delete.

You want to learn how to ModelBind to a Collection. There are many answers here already for this technique.

Do you mean something like this?.
<table class="table" style="vertical-align: middle;">
<thead>
<tr>
<th>
#Html.DisplayNameFor(model => model.title)
</th>
<th style="text-align: center;">
#Html.DisplayNameFor(model => model.imgAr)
</th>
<th>
#Html.DisplayNameFor(model => model.created)
</th>
<th></th>
</tr>
</thead>
<tbody id="tblOfContent">
#foreach (var item in Model)
{
<tr>
<td>
#Html.DisplayFor(modelItem => item.title)
</td>
<td style="text-align: center;">
<img src="~/newsImages/#item.imgAr" class="img-thumbnail" />
</td>
<td>
#item.created.ToShortDateString()
</td>
<td>
#Html.ActionLink("Details", "Edit", new { id = item.id }) |
#Html.ActionLink("Details", "Details", new { id = item.id })
</td>
</tr>
}
</tbody>
</table>
and in the Controller something like this:
public ActionResult Index()
{
return View(newsService.GetAll().OrderByDescending(x => x.created));
}
