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

asp-for binding and route-value issues inside loop

I am building a little website where users can manage personal gear, which has a name and mass among other properties. I want to display all of this gear in a table, using input boxes bound to each item so the user can change values if desired, then hit an edit button and update the gear database. I can get my foreach loop to bind all of the right values, but when it routes to the handler, it always sets the EditGearName and EditGearMass value to whatever value is in the first row.
<table>
#foreach (var g in Model.Gears) {
<tr class="list-table-main">
<td><input class="form-control" asp-for="EditGearName" value="#g.GearName" /></td>
<td><input class="form-control" asp-for="EditGearMass" value="#g.Mass" type="number" min="0" /></td>
<td style="width:12.5%"><button type="submit" asp-page-handler="EditGear" asp-route-groupid="#gg.ID">Save</button></td>
</tr>
}
</table>
Here is an example of my handler method called on the button press. The GearBL.EditGear method is code behind that handles saving it to database. I know this works (so long as the right values are passed in)
public IActionResult OnPostEditGroup(int groupid)
{
try
{
base.OnGetParent();
if (string.IsNullOrEmpty(EditGearName))
throw new ValidationException("Gear name must not be empty");
if (EditGearMass < 0)
throw new ValidationException("Gear mass cannot be less than 0");
GearBL.EditGear(groupid, User, EditGearName, EditGearMass, false);
Response.Redirect("GearList");
}
catch (Core.Domain.ValidationException ve)
{
ModelState.AddModelError("Error", ve.Message);
}
return Page();
}
I am new to asp.net/razor so any help would be appreciated. I'm not sure I even have the best way to implement something like either.

it always sets the EditGearName and EditGearMass value to whatever value is in the first row.
You should add the form tag in the foreach loop to enable one submit for one row.
<table>
<form>
#foreach (var g in Model.Gears) {
<tr class="list-table-main">
<td><input class="form-control" asp-for="EditGearName" value="#g.GearName" /></td>
<td><input class="form-control" asp-for="EditGearMass" value="#g.Mass" type="number" min="0" /></td>
<td style="width:12.5%"><button type="submit" asp-page-handler="EditGear" asp-route-groupid="#gg.ID">Save</button></td>
</tr>
}
</form>
</table>

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.

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.

How to access rows from multiple tbody in a table?

I have something like this:
<table id="tableId" runat="server">
<thead>
<tr>
<th>Example thead1</th>
<th>Example thead2</th>
</tr>
</thead>
<tbody id="tb0">
<tr>
<td>Example 1</td>
<td>Something</td>
</tr>
</tbody>
<tbody id="tb1">
<tr>
<td>Example 2</td>
<td>Something</td></tr>
</tbody>
<tbody id="tb2">
<tr>
<td>Example 3</td>
<td>Something</td>
</tr>
</tbody>
</table>
I use multiple "tbody" with different IDs so I can delete it or create it anytime I want.
What I'd like to do is getting each row from multiple "tbody" from the table "tableId".
In C#, if I use the command "tableId.Rows[0].Cells[0].InnerHtml", I get the result: "Example thead1".
But if I use "tableId.Rows[3].Cells[0].InnerHtml", I can't get the "Example 3" as available in table row, instead of it I get an error which says that row doesn't exist or it's out of index.

I have tested the your code. and found that tableId.Rows[3].Cells[0].InnerHtml will give always Example 3 ..that's is correct as per your aspx markup code.
i think you have place row index incorrect i.e. something like below
tableId.Rows[4].Cells[0].InnerHtml which not exist in your table structure.
that's why you get error of Specified argument was out of the range of valid values.Parameter name: index
Hope this will helps you...happy coding...

Make the tbody elements server controls.
<tbody id="tb2" runat="server">
<tr>
<td>Example 3</td>
<td>Something</td>
</tr>
</tbody>
Then toggle the visibility as you need:
tb2.Visible = true / false;
As per comment:
Probably the designer doesn't create a reference to tb1, tb2, tb3 controls because they are inner controls of tableId.
If so:
var tb2 = tableId.FindControl("tb2");
tb2.Visible = ...

You could use JQuery, something like this....
$('tbody', '#tableid');
But I guess depends on what you want to do with them, and where
