I have a simple drop down list and I want the indexchange event to
fire when the user changes the index to 0. So, in other words, I want
the form to sumbit only when I change to index = 0, otherwise, it dont
submit.
At first, I turned on autopostback, and asp.net adds the
onchange="__doP ostBack('id', '') to my drop down list on the client
side. This basically just submits everytime I changes the index. With
this code, it event always when I submit.
Then I turned off autopostback, and added attributes to my drop down
list. The attribute added is onchange, value is
"if(this.select edIndex==0){__d oPostBack('id', '')}". So, when the page
is rendered, I get onchange="if(th is.selectedInde x==0){__doPostB ack('id','')}"
in my drop down list. This looks right. So I go about changing the
index. When I change the index to 0, the form submits, BUT the event
does not fire.
I then changed the attribute to just "__doPostBack(' id','')" and with
this attribute, the form submits and the event is fired.
Now, the question is, why doesn't the first attribute work? 0 1123 This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

The following script if run in Internet Explorer should
display a thumbview of a webpage that you point it to.
To test it, replace test.htm with a valid html file.
The problem I'm having is that I can't get onclick to
fire on the rendered Thumbview object. What's strange
is that onmouseover fires. Can anyone see a way?
<html><head><title>test</title></head>

I posted this on the asp.net group, also. I wasn't sure whether this was an
asp.net problem or a javascript problem.
I have a page that was originally created from a program I found on the net
that works well as an html page.
It brings up a modal popup window that I have been trying to work out for

Group,
How would I go about firing a JavaScript method from a C# method in the aspx code behind file? It seems as though this could not be done since JavaScript is executed from within the Web browser and C# is executed on the server.
Thanks for your consideration,
Jim

I've been reading through quite a bit regarding this topic but am
finding myself confused.
Here is the scenario:
I have a javascript class defined with methods whereas each has
references to "this." As everyone is aware of, when you attach and
event from an element to a class method and the class method
references "this", the scope of "this" refers not to the class but
rather to the element firing the event.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
