The trouble is that message tells you (and us) nothing useful. And I am afraid I don't know AJAX, so cannot suggest anything on that score. Obviously adding some logging information should go some way to helping you to a solution.

Ok,
I will keep at it.
I would have preferred to NOT go this route of using JSON and Ajax calls but I have not been able to figure out a way to continue using the code Richard D wrote for using AngularJS with the PHP bit.
Thanks for your help though.

I'd start by using Fiddler or the browser's dev tools to see what is being passed to and from your webmethod as that can often help tracking down issues, and if your server code is throwing an exception it often lets you see what that exception is
Using the browser's dev tools to diagnose ajax problems (and other things) | The ASP.NET Forums[^]
I'd also debug the webmethod at the project to inspect the data come into the method and to see if the deserialisation is working or if the code is throwing exceptions.

I am still pretty stumped by this issue.
I have moved past the initial problem.
Right now, when i run the app, it is inserting records to the database correctly.
However, this works for only one class.
When I add a second class or table, I start getting a very deceitful error message.
For instance, when I run the app with one class:
It works.
When I run the second class separately too, it works as well.
However, when I combine them which is the real intent of this project, I keep getting "parameter @name is required but not supplied"
I have tested the stored procedure that I am using in Sql Server Management Studio and it works fine.
There is one critical step that I am missing but not sure how to fix this. I wonder if it is not possible to have multiple INSERT statements using Ajax and webmethods.
Below is the code that I am currently using.
<script type="text/javascript">
$(document).ready(function () {

Look at the sprInsertDisclsosures SP, does it define a "@name" parameter? If so look at the list of params you are adding to the command, none define @name.
You also have nested document.ready functions in your javascript, not sure that is going to work. Define a single document.ready and put everything you need into it.
|
|

|

Hi,
As stated in my last post, I tested the stored proc separately and it works a treat.
So, those params match exactly the ones you see in my code.
That's why I said it is showing deceitful error message.
Normally, that error would indicate that the @parameter is either not supplied or misspelled.
None of this is the case.
All of this struggle is because I am trying to create about 4 dynamic rows each with its own Add More button like the screenshot below:
Dynamic Rows[^]
I was able to do this in PHP with the help of Richard Deeming but management wants it done asp.net after those exhaustive efforts doing it in PHP.
I have scoured everywhere on the web looking for examples but I can find just one with one Add More Row button.

|

Computers don't make mistakes, but people do  If I had a penny for every time a developer swore they hadn't misspelled something only for me to look and realise they had, or were looking at the wrong SP etc, I'd probably have £3.82.

Is that a typo in your question? Based on the rest of your code, the class should be data-contact-person, without the trailing "m".
samflex wrote: parameter @name is required but not supplied
Are you absolutely sure the error message mentions the @name parameter? As F-ES Sitecore said, you're not passing a parameter called @name to the stored procedure, so if that's a required parameter, it would explain the error.
Alternatively, if the error is referring to one of the parameters you have defined, it's probably because one of the properties is Nothing. If you pass Nothing to the command parameter, the parameter will use its default value as defined in the stored procedure. If it doesn't have a default value, you'll get the "parameter not supplied" error.
The simplest solution would be to set a default value on the parameters of your stored procedure:
ALTER PROC sprInsertDisclsosures
(
@ename nvarchar(50) = Null,
@email nvarchar(200) = Null,
@title nvarchar(20) = Null,
@sname nvarchar(50) = Null,
@saddress nvarchar(max) = Null,
@sincome varchar(10) = Null
)
As

Hi Richard,
First of all, just to make sure I have all my information out there, this is where I got the code i am currently using.
Add And Delete HTML Table Rows Dynamically Using ASP.NET[^]
I just modified to what it is right now.
No, that is not a typo.
Those are being called with the ajax call like:
function getAllEmpData() {
var data = [];
$('tr.data-contact-personm').each(function () {
var ename = $(this).find('.employeename01').val();
var etitle = $(this).find('.employeetitle01').val();
var email = $(this).find('.employeeemail01').val();
var alldata = {
'emplName': ename,
'emplTitle': etitle,
'empMail': email
}
data.push(alldata);
});
console.log(data);
return data;
}
Then
function getAllEmpData() {
var data = [];
$('tr.data-contact-person').each(function () {
function getAllEmpData() {
var data = [];
$('tr.data-contact-person2').each(function () {
etc.
In other words, any unique Add More button has its own row as in tr.data-contact-person. At least that's how I understand.
As for the error message, sorry it mentions @sname which is the alias for sourcename.
If I run these dynamic rows individually, they work just fine.
First instance, if I run the row that contains employeename, employeetitle and employeeincome, inserts correctly into the database.
Similarly, if I run the row that contains sourcename (@sname), sourceaddress, and sourceincome, it works just fine.
It is when I try to combine them that I get the error.
I suspect that ajax calls would not allow multiple INSERT statements.
As for the stored proc, I have it declared correctly. I wish that was the source of the error that I am having. I would have resolved it by now.
This is the stored proc just so you know:
CREATE PROCEDURE [dbo].[sprInsertDisclsosures]
@ename varchar(50),
@title varchar(50),
@email varchar(50),
@sname varchar(150),
@saddress varchar(100),
@sincome numeric(18,2)
as
BEGIN
SET NOCOUNT OFF;
INSERT INTO EMPLOYEES (employeeName, empTitle, email) Values (@ename,@title,@email);
declare @ID int
set @ID = SCOPE_IDENTITY()
if @@rowcount > 0
INSERT INTO SourceDetails (sourcename,sourceaddress, sourceincome,EmployeeID) Values (@sname, @saddress,@sincome, @ID);
END
If I test it from SSMS, it inserts records into Employees table, gets the last inserted ID and inserts into SourceDetails table. So, I don't think there is an issue here.

samflex wrote: No, that is not a typo.
Then there's a fundamental problem with your code. $('.data-contact-person') is not going to match a row with the class set to data-contact-personm - the trailing "m" makes it a completely different class name.
samflex wrote: As for the stored proc, I have it declared correctly.
As I said, if you pass a value of Nothing to a parameter without a default value, you'll get the exception.
Your parameters do not have default values. Therefore, if any property on your Employee class is Nothing, you'll get this error.
Also, it's not clear what you're trying to achieve. You have multiple employee rows, and multiple source rows, but there is no connection between the two.
You could have three employees and one source - what values are you going to post for the seconds and third employees?
Conversely, you could have three source rows and no employee rows, which would give you no parent record for the SourceDetails rows.

I am trying to recreate in asp.net what we did in php where we have an employee information just once and then one or more soureces of income (sourcename, sourceaddress and source income).
I could not try to accomplish it with the same AngularJS code because asp.net as you know does not like duplicate control IDs.
Maybe I am using the code I posted incorrectly but the objective is to have a one to many relationship between employee and sourcedetails table and other tables as needed.
The code for employee is . $('.data-contact-personm') which matches this class ata-contact-personm unless I posted something different.

Well, I'm getting confused.
Your first message in this thread[^] has data-contact-person rows containing the source details, and data-contact-person2 rows containing spouse details. Your getAllEmpData function tries to read the spouse details from the source row, which isn't going to work.
Your message from four hours ago[^] has data-contact-personm rows containing the details of multiple employees, and data-contact-person rows containing the source details. Your getAllSourcepData attempts to read both employee and source details from the data-contact-person rows, which won't work.
Your Employee class seems to have a one-to-one relationship between the employee details and the source details. Your SQL tables seem to be set up for a one-to-many relationship between employees and sources, but your stored procedure only allows for a one-to-one relationship. Your description above indicates you want a one-to-many relationship.
If you just want one employee with multiple sources of income, why have you got code to add new employee rows?
"These people looked deep within my soul and assigned me a number based on the order in which I joined."
- Homer

Ok, reset time. Sorry for the confusion.
Here is what I wanted to do initially.
Have an employee row with no option to add more rows.
Then have sourcedetails rows that allows users to click to add more rows.
Then have spouse rows that allows users to click to add more rows.
So essentially, one employee to one or many sources/spouse details.
That was the original intent.
Then I tested for just employee only.
That employee code you see now with the #emptable and #empdata is for the following:
<table id="emptable">
<thead>
<tr>
<th>Employee Name</th>
<th>Title</th>
<th>Email</th>
</tr>
</thead>
<tbody>
<tr class="data-contact-person">
<td>
<input type="text" style="width:200px;" name="employeename" class="form-control employeename01" placeholder="Your name..." /></td>
<td>
<input type="text" style="width:200px;" name="employeetitle" class="form-control employeetitle01" placeholder="Your title..." /></td>
<td>
<input type="text" style="width:200px;" name="employeeemail" class="form-control employeeemail01" placeholder="Your email address..." /></td>
</tr>
</tbody>
</table><br /><br />
So you can see from here that I removed the
Add More button here. This way, employee can only be added once.
When I tested it, it inserted the records successfully.
Then I created one for sourcedetails and again it inserted successfully.
Finally, I created one for spousedetails and once again, it inserted into the database successfully.
Then I started to try to combine employee and sourcedetails.
If that worked, then i would have added SpouseDetails but it didn't work.
So, I started experimenting.
I think that's when the confusion came in.

Hi,
I have a site published on server. There are two gridview in one page, one redirect to a page where user fill the data in gridview and save it. The next gridview show the ids saved by user from first list. when the user click on the id it redirect to same page with data associated to that id. most of the time its working fine but sometime it gives an error of input string was not in a correct format. when i try to debug with my code it works fine and after I recycle the application pool of site it works fine.

It is impossible to guess what may be happening. All you can do is further debugging/logging to capture the data when it fails.

May be it is causing because of syntax error

That is not possible since no one can guess where it occurs or what your code is doing.

Why do you believe that re-installing will fix a (probable) bug in your code.
The only way to resolve issues like this is to do extensive debugging and testing. You first need to identify where the error occurs and try to determine the circumstances that cause it.

Hello, i am in the process of learning ASP.net and ajax and i stumbled upon a issue. I made a web form application in which i have c# method for image upload and also a ajax function which is giving me issues.
this is my Default.aspx file:
<form id="form1" runat="server">
<div>
<asp:FileUpload ID="FileUpload1" runat="server" />
<br />
<br />
<a href="#" id="btnImg" onclick="uploadImg()" runat="server">UPLOAD</a>
</div>
</form>
<script>
function uploadImg(){
var formData = new FormData();
formData.append('FileUpload1', $("input[type=file]")[0].files[0]);
$.ajax({
type: "POST",
url: 'Default.aspx/imageUpload',
data: formData,
contentType: 'application/json; charset=utf-8',
success: function (data) {
alert(data);
}
});
}
</script>
and this is my Default.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
}
[WebMethod]
protected void imageUpload(object sender, EventArgs e)
{
if (FileUpload1.HasFile)
{
string fileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
Guid _fileNameRandom = Guid.NewGuid();
string _fileNameStr = _fileNameRandom.ToString();
FileUpload1.PostedFile.SaveAs(Server.MapPath("/Images/") + (_fileNameStr + fileName));
Response.Redirect(Request.Url.AbsoluteUri);
}
}
When i run it i get this error in the chrome console:
Quote: Uncaught TypeError: Illegal invocation
at e (jquery.min.js:4)
at xb (jquery.min.js:4)
at Function.r.param (jquery.min.js:4)
at Function.ajax (jquery.min.js:4)
at uploadImg (Default.aspx:33)
at HTMLAnchorElement.onclick (Default.aspx:21)
I assume i didnt do the ajax call correctly, but i cant figure out the problem as im farely new in this field.

Hi,
I am facing too many kill wait alerts issue with my web site.. If we are searching for more results or if response time is late then we are facing kill wait continuously.. Is there any way to avoid or close kill wait popups by using asp.net? If possible please let me know.. It is very helpful to me... Thank you in advance...

If you're not working over a particularly slow network connection, then you generally shouldn't be getting those. If you're getting that from trivial operations that would be a strong indicator that something is wrong with either the configuration or the code.
If you have business requirements for intensive, long-running operations then you might want to build a model that stores process results and queries those periodically.

Use asynchronous ajax calls when doing your searching etc and they shouldn't trigger the wait dialog.

Are you referring to when the browser says something like "The page has become unresponsive?" If so, you need to optimize your code. Implement smaller paging of data or at least figure out what is causing so much slowness and then fix it.
There are two kinds of people in the world: those who can extrapolate from incomplete data.
There are only 10 types of people in the world, those who understand binary and those who don't.
