How can I hide a webform button from controller action? or Do I do it in webform itself?
There is a condition to hide/disable the button:
if (StudentType != "Senior")
{
Hide Button
}
Display Button
View:
<form method="post" action="/Student/Dispatch/">
<label for="id">Student Number: </label>
<input type="text" name="id" value="" /> <br /><br />
<input type="submit" value="Get Student(xls)" name="xls" />  
<input type="submit" value="Get Student(pdf)" name="pdf" />
</form>
Controller:
[HttpPost]
public ActionResult Dispatch(string pdf, string id) {
if (!string.IsNullOrEmpty(pdf)) {
// GetPdf submit button was clicked
return StudentPdf(id);
}
// GetXls submit button was clicked
return StudentExcel(id);
}
You can use ViewData dictionary .
Controller:
if (StudentType != "Senior")
{
ViewData["isHideButton"] =true;
}
View:
<form method="post" action="/Student/Dispatch/">
<label for="id">Student Number: </label>
<input type="text" name="id" value="" /> <br /><br />
<% bool hideButton= false;
bool.TryParse(ViewData["isHideButton"],hideButton)%>
<%if(!hideButton)
{%>
<input type="submit" value="Get Student(xls)" name="xls" />
<%}%>
  <input type="submit" value="Get Student(pdf)" name="pdf" />
</form>

I am working on captcha authentication. I want to get user entered captcha value in controller's Index method. Below is my cshtml file code
#{
ViewData["Title"] = "Home Page";
}
<div class="container">
<label for="captcha"><b>Enter chaptcha - </b></label>
<label id="lblshowCaptcha"><b>#ViewData["captcha"]</b></label>
<input id="txtCapValue" type="text" placeholder="Enter captcha" name="cap" required>
<br/>
<button class="button" type="submit">Login</button>
<br />
</div>
When user entering captcha value in txtCapValue and click submit button I need that value in controller. Here is my controller
public IActionResult Index()
{
randnumber = RandomString(6);
ViewData["captcha"] = randnumber;
return View();
}
how can I get txtCapValue input control value when user click on submit button ?
One of the easy ways using the Form Tag Helper:
<form asp-controller="Controller_Name" asp-action="Captcha" method="post">
<div class="container">
<label for="captcha"><b>Enter chaptcha - </b></label>
<label id="lblshowCaptcha"><b>#ViewData["captcha"]</b></label>
<input id="txtCapValue" type="text" placeholder="Enter captcha" name="cap" required>
<br />
<button class="button" type="submit">Login</button>
<br />
</div>
</form>
And on the server side:
[HttpPost]
public IActionResult Captcha(string cap)
{
... using the `cap`
return View("Index");
}
I want to get user entered captcha value in controller's Index
method.
There are two options, you can try:
Option1: use Form Tag Helper
Index method:
public IActionResult Index(string cap)
{
ViewData["captcha"] = 6;//do your staff
return View();
}
Index view:
<form method="get" asp-action="Index">
<div class="container">
<label for="captcha"><b>Enter chaptcha - </b></label>
<label id="lblshowCaptcha"><b>#ViewData["captcha"]</b></label>
<input id="txtCapValue" type="text" placeholder="Enter captcha" name="cap" required>
<br />
<button class="button" type="submit">Login</button>
<br />
</div>
</form>
Option 2: use ajax
Index method:
public IActionResult Index(string cap)
{
ViewData["captcha"] = 6;
return View();
}
Index view:
<div class="container">
<label for="captcha"><b>Enter chaptcha - </b></label>
<label id="lblshowCaptcha"><b>#ViewData["captcha"]</b></label>
<input id="txtCapValue" type="text" placeholder="Enter captcha" name="cap" required>
<br />
<button id="buttonDemo1" class="button" type="submit">Login</button>
<br />
</div>
#section scripts{
<script type="text/javascript">
$(document).ready(function () {
$('#buttonDemo1').click(function () {
var cap = $("#txtCapValue");
$.ajax({
type: 'GET',
url: '/Home/Index',
data: cap
});
});
});
</script>
}
result:
If I click save I want to redirect to userslist view and when I click save and new I want to redirect again to add users view and script "save successfully" but it is too hard to solve. Does anybody have an idea to fix this issue?
This is my view in add form.
<form method="post" action="<?php echo site_url('users/add')?>" >
<label>FirstName</label>
<input type="text" name="first_name" placeholder="Firstname"required>
<label>LastName</label>
<input type="text" name="last_name" placeholder="Lastname"required>
<label>Email</label>
<input type="email" name="email" placeholder="Email"required>
<label>Username</label>
<input type="Username" name="username" placeholder="Username"required>
<label>Password</label>
<input type="password" name="password" id="password" placeholder="Password"required>
<label>Confirm Password</label>
<input type="password" placeholder="Confirm Password" id="confirm_password" required>
<label>Permissions</label>
<input type="text" name="permissions" placeholder="Permissions"required>
<label>Role ID</label>
<input type="text"required name="role_id" placeholder="Role ID"required>

<input type="text"required name="created_by" placeholder="Created By"required>
<button type="submit" value="formSave">SAVE</button>
<button type="submit" value="formSaveNew">SAVE AND ADD NEW</button>
This is my controller to add
public function add()
{
$this->data['page_title'] = "Add User";
$input_data = $this->input->post();
if(!empty($input_data)){
$this->User_model->insert($input_data);
redirect('/users');
} else {
$this->load->view('templates/master', $this->data);
}
}
here is my code
this is simple form. I am trying to call on click event on button click
render: function () {
return (
<form className="commentForm">
<input
type="text"
placeholder="Your name"
value={this.state.author}
onChange={this.handleAuthorChange}
/>
<input
type="text"
placeholder="Say something..."
value={this.state.text}
onChange={this.handleTextChange}
/>
<input type="submit" value="Post" />
</form>
);
You forgot to pass the onSubmit event for form
render: function () {
return (
<form className="commentForm" onSubmit={this.submit}>
<input
type="text"
placeholder="Your name"
value={this.state.author}
onChange={this.handleAuthorChange}
/>
<input
type="text"
placeholder="Say something..."
value={this.state.text}
onChange={this.handleTextChange}
/>
<input type="submit" value="Post" />
</form>
);
submit: function() {
// do your stuff
}
try this:
<form className="commentForm" onSubmit={this.handleSubmit}>
<input
type="text"
placeholder="Your name"
value={this.state.author}
onChange={this.handleAuthorChange}
/>
<input
type="text"
placeholder="Say something..."
value={this.state.text}
onChange={this.handleTextChange}
/>
<input type="submit" value="Post" />
</form>
Can you try like this
handleTextChange(e) {
const { name, value } = e.target;
this.setState({
[name]: value
});
}
_handleSubmit(e) {
e.preventDefault();
let { author, text} = this.state;
// dispatch the submit function
}
render: function () {
return (
<form className="commentForm" onSubmit={this._handleSubmit}>
<input
type="text"
placeholder="Your name"
name="author"
value={this.state.author}
onChange={this.handleAuthorChange}
/>
<input
type="text"
placeholder="Say something..."
name="text"
value={this.state.text}
onChange={this.handleTextChange}
/>
<input type="submit" value="Post" />
</form>
);
u want onclick method here it is onsubmit same work of onclick.
handleSubmit(){
console.log(this.state.author);// u can see the value of autor and say somthing input vale in here it is coming right value or not
console.log(this.state.text);
axios.post(route,{
name:this.state.author, //these name and say are the variable whice are use to take the values to back end
Say :this.state.text
}).then({response}); //here u cn give some thing to disply after data add to database.
}
<form className="commentForm" onsubmit={this.handleSubmit.bind(this)}>
<input
type="text"
placeholder="Your name"
value={this.state.author}
onChange={this.handleAuthorChange}
/>
<input
type="text"
placeholder="Say something..."
value={this.state.text}
onChange={this.handleTextChange}
/>
<input type="submit" value="Submit" />
</form>
You need not have separate onChange for two fields unless you do something different in each of them.
Render:
<form className="commentForm" onSubmit={this.handleSubmit}>
<input
type="text"
placeholder="Your name"
name="author"
onChange={this.handleChange}
/>
<input
type="text"
placeholder="Say something..."
name="text"
onChange={this.handleChange}
/>
<button type="submit" >submit</button>
</form>
When submit is clicked :
handleSubmit = (e) => {
e.preventDefault();
console.log(this.state.author) //whatever you want to process the data with...
}
You can have single handleChange to set the state
handleChange = (e) => {
const { value, name } = e.target;
this.setState({ [name]: e.target.value })
}
Below is a group of radio buttons that appear on my view. I am able to retrieve the selected item via this simple code
string criteria = filter["criteria"];
however I do not know how to retain the selected item. Once the controller posts back to the view the default radio button is always selected.
<form method="post">
#Html.TextBox("searchValue", ViewBag.CurrentFilter as string, new { placeholder = "Search" })
<input type="image" src="#Url.Content("~/Content/Images/Filter.bmp")" alt="Filter" style="padding-top: 0px;" />
<span class="error" style="clear: both;">
#ViewBag.ErrorMessage
</span>
<br />
<br />
<input type="radio" name="criteria" id="bankName" value="bankName" checked="true"/>
<label for="bankName">Bank Name</label>
<input type="radio" name="criteria" id="EPURL" value="EPURL" />
<label for="EPURL">EPURL</label>
<input type="radio" name="criteria" id="specialNotes" value="specialNotes" />
<label for="SpecialNotes">Special Notes</label>
<input type="radio" name="criteria" id="email" value="email" />
<label for="email">Email</label>
<input type="radio" name="criteria" id="dynamicsId" value="dynamicsId" />
<label for="dynamicsId">Dynamics ID</label>
<input type="radio" name="criteria" id="stat" value="stat" />
<label for="fixed">Agent ID </label>
</form>
The answer to this question wound up being incredibly simple. First mistake I made was not using the #Html controls. Second was using FormCollection as an input parameter for the index controller. By changing the radio buttons to the following:
#Html.RadioButton("criteria", "bankName", true)<span>Bank Name</span>
#Html.RadioButton("criteria", "EPURL")<span>EPURL</span>
#Html.RadioButton("criteria", "specialNotes")<span>Special Notes</span>
#Html.RadioButton("criteria", "email")<span>Email</span>
#Html.RadioButton("criteria", "dynamicsId")<span>Dynamics ID</span>
#Html.RadioButton("criteria", "stat")<span>Agent ID</span>
and the signature of the Index method in the controller to this:
public ActionResult Index(string criteria, string searchValue)
The selected radio button stayed selected after the post back.
If I understand your need correctly you could set the name of the item you want checked in the ViewBag (or ViewData or Model) and set the checked property in your view accordingly. Something like this:
<form method="post">
#Html.TextBox("searchValue", ViewBag.CurrentFilter as string, new { placeholder = "Search" })
<input type="image" src="#Url.Content("~/Content/Images/Filter.bmp")" alt="Filter" style="padding-top: 0px;" />
<span class="error" style="clear: both;">
#ViewBag.ErrorMessage
</span>
<br />
<br />
#{
var checkedItemName = ViewBag.CheckedItemName;
}
<input type="radio" name="criteria" id="bankName" value="bankName" checked="#((checkedItemName == "bankName"))"/>
<label for="bankName">Bank Name</label>
<input type="radio" name="criteria" id="EPURL" value="EPURL" checked="#((checkedItemName == "EPURL"))"/>
<label for="EPURL">EPURL</label>
<input type="radio" name="criteria" id="specialNotes" value="specialNotes" checked="#((checkedItemName == "specialNotes"))"/>
<label for="SpecialNotes">Special Notes</label>
<input type="radio" name="criteria" id="email" value="email" checked="#((checkedItemName == "email"))"/>
<label for="email">Email</label>
<input type="radio" name="criteria" id="dynamicsId" value="dynamicsId" checked="#((checkedItemName == "dynamicsId"))"/>
<label for="dynamicsId">Dynamics ID</label>
<input type="radio" name="criteria" id="stat" value="stat" checked="#((checkedItemName == "stat"))"/>
<label for="fixed">Agent ID </label>
</form>
Don't refresh the complete page...Use JQuery and do an Ajax call
$.ajax({
url: "Your Url",
async: true,
type: 'POST',
data: JSON.stringify({ ParameterName: Param_Value }),
beforeSend: function (xhr, opts) {
},
contentType: 'application/json; charset=utf-8',
complete: function () { },
success: function (data) {
//Success Callback
//Code to set value to your control
}
});
I have a basic form for which I want to handle buttons inside the form by calling the ActionResult method in the View's associated Controller class. Here is the following HTML5 code for the form:
<h2>Welcome</h2>
<div>
<h3>Login</h3>
<form method="post" action= <!-- what goes here --> >
Username: <input type="text" name="username" /> <br />
Password: <input type="text" name="password" /> <br />
<input type="submit" value="Login">
<input type="submit" value="Create Account"/>
</form>
</div>
<!-- more code ... -->
The corresponding Controller code is the following:
[HttpPost]
public ActionResult MyAction(string input, FormCollection collection)
{
switch (input)
{
case "Login":
// do some stuff...
break;
case "Create Account"
// do some other stuff...
break;
}
return View();
}
you make the use of the HTML Helper and have
#using(Html.BeginForm())
{
Username: <input type="text" name="username" /> <br />
Password: <input type="text" name="password" /> <br />
<input type="submit" value="Login">
<input type="submit" value="Create Account"/>
}
or use the Url helper
<form method="post" action="#Url.Action("MyAction", "MyController")" >
Html.BeginForm has several (13) overrides where you can specify more information, for example, a normal use when uploading files is using:
#using(Html.BeginForm("myaction", "mycontroller", FormMethod.Post, new {enctype = "multipart/form-data"}))
{
< ... >
}
If you don't specify any arguments, the Html.BeginForm() will create a POST form that points to your current controller and current action. As an example, let's say you have a controller called Posts and an action called Delete
public ActionResult Delete(int id)
{
var model = db.GetPostById(id);
return View(model);
}
[HttpPost]
public ActionResult Delete(int id)
{
var model = db.GetPostById(id);
if(model != null)
db.DeletePost(id);
return RedirectToView("Index");
}
and your html page would be something like:
<h2>Are you sure you want to delete?</h2>
<p>The Post named <strong>#Model.Title</strong> will be deleted.</p>
#using(Html.BeginForm())
{
<input type="submit" class="btn btn-danger" value="Delete Post"/>
<text>or</text>
#Url.ActionLink("go to list", "Index")
}
Here I'm basically wrapping a button in a link. The advantage is that you can post to different action methods in the same form.
<a href="Controller/ActionMethod">
<input type="button" value="Click Me" />
</a>
Adding parameters:
<a href="Controller/ActionMethod?userName=ted">
<input type="button" value="Click Me" />
</a>
Adding parameters from a non-enumerated Model:
<a href="Controller/ActionMethod?userName=#Model.UserName">
<input type="button" value="Click Me" />
</a>
You can do the same for an enumerated Model too. You would just have to reference a single entity first. Happy Coding!
