So have I have a modal with a updatepanel and a repeater inside it. I have an open another modal on linkbutton click, I would like to update the 2nd modal with a checkboxlist, but the linkbutton click doesn't fire for me to update the 2nd modal data.

There's a secret error somewhere in your secret code. You should fix that.

document.activeElement.id is not working in safari
|
|
|
|
|
If you wish for help with your problem then you need to edit your question and provide full details. Saying, "not working", tells us nothing.
|
|
|
|
|
Hence, you can change your event handler from:
$('#modalLogout').on('hide.bs.modal', function () {
var activeElement = $(document.activeElement);
to the delegated one:
$('#modalLogout').on('click', '#LogoutOk', function (e) {
var activeElement = $(e.target);

You'll probably want to start with the Media Capture and Streams API[^]. But that's an extremely ambitious project, especially for a beginner.
NB: Asking for help writing something without explaining precisely what help you need, what you have tried, or where you are stuck, will lead people to assume that you want someone to do all the work for you. That's not going to happen.

Can you please help on the best approach to build an API in JAVA/Dotnet which has mainframe as database.
Basically we need to expose product data information so that consumer can use them for their business analysis.
|
|
|
|
|
Exposing production data for analysis is fraught with nightmares. Business analysis is a monster and should only be done against a data wharehouse so the first thing you need to look into is wharehousing strategies. They will depend on your data size, replication speed requirement and budget.
Once you have sorted that then connection to the wharehouse is trivial. Designing the wharehouse on the other hand is an entire career.

suppose i am developing a site with ASP.Net MVC core. i have created a empty project where i add two controller.
one is Home and login controller. Home controller's index action is not protected by Authorized attribute but Home controller's product action is protected.
when user try to access product action then user should be redirected to login page if not signed in. so tell me how to setup project in classic mvc or mvc core where i will mention that user should be redirected to login page if user is not signed in.
i will not use identity rather i will check user credentials from db using ado.net.
please guide me step wise that what i need to follow. Thanks

Sir, my question was bit different. i am trying to know how asp.net mvc engine understand now user need to redirect to login page? if login controller name would be different then how asp.net mvc understand it ? where this binding done in default project when we create a default project from IDE?
i believe there must be a place where we mention that login page should come if user is not signed in when access any protected resource.
please share knowledge if you know. thanks

Please see the code.
using (Html.BeginForm("Login", "Default", new { ReturnUrl = ViewBag.ReturnUrl, data = Request.QueryString["data"] }, FormMethod.Post,
new
{
id = "idtest1",
onsubmit = "this.querySelectorAll('button').forEach(i => i.disabled = false)",
@class = "form-signin",
role = "form"
}))
{
}
specially see this line which is not clear to me. onsubmit = "this.querySelectorAll('button').forEach(i => i.disabled = false)",
in the above code BeginForm html helper has been used to render form at runtime. what will happen when form will be submitted ?
what this line will do when form submit ? onsubmit = "this.querySelectorAll('button').forEach(i => i.disabled = false)",
please help me to understand this JavaScript code objective when form submit. Thanks
|
|
|
|
|
That line sets the onsubmit attribute on the <form> element to the specified Javascript string. It's an old way of attaching an event handler to an element.
When the form is submitted, all buttons on that form will have their disabled property set to false. But that won't actually accomplish anything; a button's name and value are only submitted with the form if you click on that button, and you can't click on a disabled button.

Hello,
Quick intro, My name is Jason and recently a work colleague retired and had developed several ASPX websites of which I have been tasked to support.
My previous background of programming is around Delphi, Intersystems Cache and more recently C# but these websites that I'm now supporting are all written in VB.net, asp.net, aspx or whatever language it is called, as you have probably guessed by now I have never used Visual Studio or produced code that created aspx files.
Anyway as a newbie to this language I have run into a problem that you experts will have learnt in school 
I have a webpage (student.aspx) that contains this snippet of code :
<asp:DropDownList runat="server" ID="ddlCourse" DataTextField="Course"
DataValueField="Course" DataSourceID="SDSCourse"
Width="260px" onChange="CheckNerveCenter"/>
I have added the "onChange" bit
and this bit of code is also existing
<asp:CheckBox ID="chkNerveCentre" runat="server" Text="Nerve Centre" TextAlign="Left" />
So basically the page contains several combo boxes and several check boxes
I need to do some logic for 2 of them, code above.
If the combo box contains text (from database) with the word Nursing, Nurse, Nurses etc. lets say "*Nurs* then teh tick box needs to be disabled so it cannot be ticked
This is the code I have done in the code behind file student.aspx.vb, it just contains a comment now
Function CheckNerveCenter() As Object
'If ID="ddlCourse" contains any word like "*Nurs*" then
'uncheck ID="chkNerveCentre" and then disable ID="chkNerveCentre"
End Function
At first I tried to get it to display a message to show that it was calling the function from the "onChange" but it doesn't seem to work.
As I'm new to this language would you please just help a newbie in the right direction
I did try and use the OnChangeText in visual studio but it just kept showing me this error
"Property Value not valid","Error HRESULT E_FAIL has been returned from a call to a COM component." I have no idea what this means
That's why I decided to try and use a function of my own but now stuck
Any ideas please?
Jason

The OnChange event will run on the server, when the page posts back to the server. That normally only happens when you click a button; if you want it to happen as soon as your list changes, you'll need to set the AutoPostBack property of the list to True.
ListControl.AutoPostBack Property (System.Web.UI.WebControls) | Microsoft Docs[^]
Your event handler method will need to match the expected signature:
Protected Sub CheckNerveCenter(ByVal sender As Object, ByVal e As EventArgs)
...
End Sub
