Make input fields readonly with values based on another input field

I have 3 input fields in the create user form. Based on the selection of status, I want to make the next 2 fields read-only with specific values.
So If the user selects "Full-Time" for Status, the next 2 fields should become read-only with values 5 and 7.6 respectively. For any other selection, it should remain as a normal input field for the user to enter values.
How can I achieve this? Would highly appreciate any help

You can use listener events and jquery's method attr to handle the state of the other two text boxes. Here is an example.
function changeVal(e) {
console.log(e.target.value)
if (e.target.value == "Full Time") {
$("#workingday").val(5)
$("#workinghour").val(7.6)
$("#workingday").attr("readonly", true)
$("#workinghour").attr("readonly", true)
} else {
$("#workingday").val("")
$("#workinghour").val("")
$("#workingday").attr("readonly", false)
$("#workinghour").attr("readonly", false)
}
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<table>
<tr>
<td>status</td>
<td>Working Day in weeks</td>
<td>Working Hours Per Day</td>
</tr>
<tr>
<td>
<select onchange="changeVal(event)">
<option value="">--select--</option>
<option value="Full Time">Full Time</option>
<option value="other">other value</option>
</select>
</td>
<td>
<input type="text" id="workingday" name="workingday" value="0" />
</td>
<td>
<input type="text" id="workinghour" name="workinghour" value="0" />
</td>
</tr>
</table>

add runat attribute to Status
runat="server"
then take the value of Status and compare it to set the parameters of the other fields
String statustxt = Status.Value;
if(Equals(statustxt, targettxt) {
workingdays.Text = "5";
workingdays.ReadOnly = true;
workinghours.Text = "7.6";
workinghours.ReadOnly = true; }
You can also set Editable = false

Angular JS, multiple insert error

I want to fetch data from SQL and display in HTML table using ng-repeat option then I need to edit some values in the table cell. My problem is that I only get initial values in the controller and the changes are not reflected in the controller. Here is my code:
app.controller('CRUD_EntryController', function ($scope, CRUD_InternalEntryService) {
GetStudentMarkDetails();
function GetStudentMarkDetails() {
var PromiseGetMarks = CRUD_InternalEntryService.GetMarkDetails();
PromiseGetMarks.then(function (res) {
$scope.MarkList = res.data;
})
}
$scope.mark = {};
$scope.save = function (MarkList) {
var index = 0;
$scope.MarkList.forEach(function (mark) {
console.log('rows #' + (index++) + ': ' + JSON.stringify(mark));
alert(mark.M1);
}
}
View:
<table class=" table table-condensed" id="myresul">
<tr>
<th>Slno</th>
<th>Name</th>
<th>RegNo</th>
<th>ClassNo</th>
<th>M1</th>
<th>M2</th>
<th>M3</th>
</tr>
<tbody data-ng-repeat="mark in MarkList" >
<tr>
<td class="col-md-1" >#{{$index+1}}</td>
<td class="col-md-2" ng-model="mark.Fname">{{mark.Fname}}</td>
<td class="col-md-2">{{mark.RegNo}}</td>
<td class="col-md-1">{{mark.ClassNo}}</td>
<td class="col-md-1"><input type="number" value="{{mark.M1}}" ng-model="M1" class="form-control" /></td>
<td class="col-md-1"><input type="number" value="{{mark.M2}}" ng-model="M2" class="form-control" /></td>
<td class="col-md-1"><input type="number" value="{{mark.M3}}" ng-model="M3" class="form-control" /></td>
</tr>
<button data-ng-click="save(MarkList)" class="btn btn-success">Save</button>
</tbody>
</table>

Don't think you need to define this: $scope.mark = {}; since mark is set in the scope of your ng-repeat. Remove it because this is somewhat confusing and might cause errors in the future.
Remove the value="{{mark.M1}}" and bind your model to ng-model="{{mark.M1}}". Asuming that you wand to bind to M1, M2 and M3 in your inputs.
Also see the angular docs for ngModel for more details and update your code accordingly.
By the way you don't have to pass MarkList as an argument for Save(..), you can do this:
<button data-ng-click="save()" class="btn btn-success">Save</button>, change the Save method signature to Save() and use $scope.MarkList instead of the argument MarkList.
Or change your method to only save the specific mark instead of the entire list every time.

Error with session mvc 4

When the HomeController start in the Index ActionResults i set a session with the value of 1
Session["login_fail"] = 1;
When the user try to login the sessio variable change to 0 if it fails
Session["login_fail"] = 0;
And if it fails, here what should happen
#using(Html.BeginForm()) {
<fieldset>
<legend>Tbl_Users</legend>
<table>
<tr>
<td>User Name</td>
<td><input type="text" id="username" name="userName" /></td>
<td id="ErrorMessage"></td>
</tr>
<tr>
<td>Password </td>
<td><input type="text" id="pass" name="pass" /></td>
<td id="ErrorMessage"></td>
</tr>
#{
if(Convert.ToInt32(Session["login_fail"]) == 0)
{
<p>User name or password are incorrect. Please, try again.</p> //here should apper the error message if it fails but it doesnt
}
}
</table>
<p>
<input type="submit" onclick="return validate()" value="Login" />
</p>
</fieldset>
Notice that when i submit the form, another action is who recive the values of the post and them check if the user and password are ok, if it doesnt(that i have checked that it does return 0) it will show the error message and will be return to the Index actionresults which is in the same controller as the LoginUser(the one which return 0 or 1)

I found the error. The problem was that when i clicked submit the post values goes to another actionresuts, and then the session's value get 0 if the login failed and them make a redirecttoaction to Index actionresults again and the session's value for some reason, get lost.
The same as if you use a ViewBag, you can not see its value in another view. I dont know why this happen since session should be visible in the whole proyect. But i guest that that was the problem.

It seems like after your LoginUser() method, Index() works again and sets the Session["login_fail"] = 1; again.
You know your [Get] Index() works everytime you load the page. I suggest you to use TempData for passing data throught controller methods.
TempData["login_fail"] = 1;
So you can check if TempData is 1 or 0 in your Index() and set session according to TempData.

How to Get All HtmlInputText Controls Within a Table Row?

I'm trying to create a web page to create small playlists. Once data has been entered into the fields, it needs to be saved to an XML file. Currently the table looks like this:
<%-- song list table --%>
<table runat="server" id="table" class="table">
<%-- info row --%>
<thead>
<tr>
<td>Song Title</td>
<td>Song Artist</td>
<td>Song Album</td>
<td><%-- column for delete button --%></td>
</tr>
</thead>
<%-- input rows --%>
<tbody>
<tr>
<td><input runat="server" placeholder="Title" type="text" /></td>
<td><input runat="server" placeholder="Artist" type="text" /></td>
<td><input runat="server" placeholder="Album" type="text" /></td>
<td>
<a href="#">
<img src="Images/Delete.png" onmouseover="this.src='Images/Delete-Hover.png'" onmouseout="this.src='Images/Delete.png'" alt="Delete" />
</a>
</td>
</tr>
</tbody>
</table>
New rows will be added dynamically with jQuery. When the user clicks save, I need to write the table data into their specific XML file. Currently my backend code looks like this:
//for each row
foreach (HtmlTableRow row in table.Rows)
{
//create row info
textWriter.WriteStartElement("Row");
//for each cell
foreach (HtmlTableCell element in row.Cells)
{
//get inputs
//write current input to xml
}
//close row
textWriter.WriteEndElement();
}
My question is where I go from there with my code to be able to get the values of each input and write them to the XML.

You need to give the element's an ID so you can refer to them by. Also, any dynamically added rows will not be able to be accessed this way; that is because they do not exist in the control tree as a server control, but are a pure client control. You would have to access these using Request.Form collection. You'd have to add them dynamically to the control tree if you want them to persist across postbacks too.
If you are using JQuery, it would be more efficient and easier to grab all the values on the client and send the values to a web service or something like that.

My suggestion would be to re-think how you're gathering the data. I assume that you're going to have this information do an HTTP POST to your server using $.ajax() or something similar - and on the server-side, you're wanting to get all of the instances of the Title, Artist and Album fields, grouped by row.
Instead of posting back the table, which is a set of UI elements that display your data, but do not represent it, consider posting back to the server and having the server expect an IEnumerable of Song objects, which would look something like this:
public class Song {
public String Album { get; set; }
public String Artist { get; set; }
public String Title { get; set; }
}
Now, when you bind the form itself, you can bind something like:
<table>
<thead>
<tr>
<td>Song Title</td>
<td>Song Artist</td>
<td>Song Album</td>
<td><%-- column for delete button --%></td>
</tr>
</thead>
<tbody>
<tr>
<td><input placeholder="Title" type="text" name="Songs[0].Title" /></td>
<td><input placeholder="Title" type="text" name="Songs[0].Artist" /></td>
<td><input placeholder="Title" type="text" name="Songs[0].Album" /></td>
</tr>
</tbody>
</table>
The [0] notation indicates that this element is part of an IEnumerable called Songs, and is at index 0. When your jQuery script then goes and adds new rows, you simply increment the indexes. So - a new row would be something like:
<tr>
<td><input placeholder="Title" type="text" name="Songs[1].Title" /></td>
<td><input placeholder="Title" type="text" name="Songs[1].Artist" /></td>
<td><input placeholder="Title" type="text" name="Songs[1].Album" /></td>
</tr>
The only trick to this is to ensure that you never have gaps in your indexes. I.E. - if you have 5 rows, and you delete the third, you need to re-index rows 4 and 5 (by decrementing the [#] values).
Note: All of the above assumes you are using server-side binding.
If you are already using jQuery, you might also find it simpler to simply parse your table's input elements with jQuery and post things as an object that you have direct control over. This prevents you from having to do any indexing at all. An example would be something like:
$('#submit-button').on('click', function (ev) {
var songs = [];
$('#table > tbody > tr').each(function (index, element) {
var $tr = $(element);
var album = $tr.find('input[placeholder=Album]').val();
var artist = $tr.find('input[placeholder=Artist]').val();
var title = $tr.find('input[placeholder=title]').val();
songs.push({ Album: album, Artist: artist, Title: title });
});
$.ajax({
url: '/my/post/url',
type: 'POST',
data: songs
});
});
On the server-side, you will now receive an HTTP POST to /my/post/url which has a payload containing the song data in the table - without having to worry about funky data-binding syntax or indexing.
Hope this helps.

webBrowser setAttribute

Here is the problem
<input type='text'name='TextBox0001'/>
For example to insert a value for the input of above is just by using this code :
foreach (HtmlElement he in webBrowser1.Document.All.GetElementsByName("TextBox0001"))
{
he.SetAttribute("value", "HI");
}
That's okay but how do I insert a value for the counter if the html code written like below?
<table>
<tr id='set1_row1'>
<td> <input type='text'name='counter'></td>
</tr>
<tr id='set1_row2'>
<td> <input type='text'name='counter'></td>
</tr>
</table>
</table>
I am using c# webBrowser.

For "set1_row1" would be:
foreach (HtmlElement he in webBrowser1.Document.All.GetElementsByName("counter"))
{
if(he.Parent.Parent.getAttribute("id") == "set1_row1")
{
he.SetAttribute("value", "HI");
}
}
You get the idea, so you can figure out your exact logic based on this example.
